Theoretically, habitat loss can have vastly different impacts depending on the site’s importance within the migratory corridor. However, migration network connectivity and the impacts of site loss are not completely understood. Here we used GPS tracking data from four bird species in the Asian flyways to construct migration networks, and proposed a framework for assessing network connectivity for migratory species. We used a node removal process to identify stopover sites with the highest impact on connectivity. In general, migration networks with fewer stopover sites were more vulnerable to habitat loss. Node removal in order from the highest to lowest degree of habitat loss yielded an increase of network resistance similar to random removal. In contrast, resistance increased more rapidly when removing nodes in order from the highest to lowest betweenness value. We quantified the risk of migration network collapse and identified crucial sites by first selecting sites with large contributions to network connectivity, and then identifying which of those sites were likely to be removed from the network (i.e., sites experiencing habitat loss). Among these crucial sites, 42% were not designated as protected areas. Setting priorities for site protection should account for the site’s position within the migration network, rather than only site-specific characteristics. Our framework for assessing migration network connectivity enables site prioritization for conservation of migratory species.","language":"English","publisher":"Wiley","doi":"10.1111/cobi.13383","usgsCitation":"Xu, Y., Si, Y., Takekawa, J., Liu, Q., Prins, H.H., Yin, S., Prosser, D.J., Gong, P., and de Boer, W.F., 2019, A network approach to prioritize conservation efforts for migratory birds: Conservation Biology, v. 34, no. 2, p. 416-426, https://doi.org/10.1111/cobi.13383.","productDescription":"11 p.","startPage":"416","endPage":"426","ipdsId":"IP-104639","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":467484,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/cobi.13383","text":"Publisher Index Page"},{"id":373481,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"34","issue":"2","publishingServiceCenter":{"id":10,"text":"Baltimore PSC"},"noUsgsAuthors":false,"publicationDate":"2019-08-16","publicationStatus":"PW","contributors":{"authors":[{"text":"Xu, Yanjie","contributorId":223541,"corporation":false,"usgs":false,"family":"Xu","given":"Yanjie","email":"","affiliations":[{"id":40738,"text":"Tsinghua University","active":true,"usgs":false}],"preferred":false,"id":785388,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Si, Yali","contributorId":223542,"corporation":false,"usgs":false,"family":"Si","given":"Yali","email":"","affiliations":[{"id":40738,"text":"Tsinghua University","active":true,"usgs":false}],"preferred":false,"id":785389,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Takekawa, John 0000-0003-0217-5907","orcid":"https://orcid.org/0000-0003-0217-5907","contributorId":203688,"corporation":false,"usgs":false,"family":"Takekawa","given":"John","affiliations":[{"id":36688,"text":"Suisun Resource Conservation District","active":true,"usgs":false}],"preferred":false,"id":785390,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Liu, Qiang","contributorId":216855,"corporation":false,"usgs":false,"family":"Liu","given":"Qiang","email":"","affiliations":[{"id":39533,"text":"4.\tGraduate student, CHWR, Hohai University, NO.1, Xikang Road, Nanjing 210098, China","active":true,"usgs":false}],"preferred":false,"id":785391,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Prins, Herbert H.T.","contributorId":223543,"corporation":false,"usgs":false,"family":"Prins","given":"Herbert","email":"","middleInitial":"H.T.","affiliations":[{"id":37803,"text":"Wageningen University","active":true,"usgs":false}],"preferred":false,"id":785392,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Yin, Shenglai","contributorId":223544,"corporation":false,"usgs":false,"family":"Yin","given":"Shenglai","email":"","affiliations":[{"id":37803,"text":"Wageningen University","active":true,"usgs":false}],"preferred":false,"id":785393,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Prosser, Diann J. 0000-0002-5251-1799 dprosser@usgs.gov","orcid":"https://orcid.org/0000-0002-5251-1799","contributorId":2389,"corporation":false,"usgs":true,"family":"Prosser","given":"Diann","email":"dprosser@usgs.gov","middleInitial":"J.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":785394,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Gong, Peng","contributorId":197939,"corporation":false,"usgs":false,"family":"Gong","given":"Peng","email":"","affiliations":[{"id":25577,"text":"Ministry of Education Key Laboratory for Earth System Modeling, Center for Earth System Science, Tsinghua University, Beijing, China","active":true,"usgs":false}],"preferred":false,"id":785395,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"de Boer, Willem F.","contributorId":223546,"corporation":false,"usgs":false,"family":"de Boer","given":"Willem","email":"","middleInitial":"F.","affiliations":[{"id":37803,"text":"Wageningen University","active":true,"usgs":false}],"preferred":false,"id":785396,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Yet there is still a gap in knowledge of how human dimensions of drought impacts, planning, and resilience are similar and different across cases and regions. Building on the natural science understanding developed by the USGS’ various ecological drought projects as well as a range of other place-based social science case studies of drought and its impacts, this project explored human dimensions of ecological drought across the intermountain west from a comparative, regional perspective. The Working Group brought together agency and university experts in the field of drought social science, including researchers affiliated with the North Central and South Central Climate Adaptation Science Centers (USGS), Western Water Assessment (a NOAA RISA program), the Northern Plains Climate Hub (USDA), and the USGS-supported SNAPP Ecological Drought Working Group. The group held three virtual meeting during Spring 2018 in preparation for an extended in-person workshop in June 2018 in Fort Collins, CO, followed by monthly calls to finalize products.  The group’s objectives were to (1) integrate insights from existing social science studies of drought to identify commonalities and trends that generalize across cases while simultaneously accounting for the complexity experienced in particular places by individual decision makers, (2) develop a common lexicon and analytic framework for understanding drought across the Intermountain West from a social-ecological systems perspective, (3) identify emergent research themes, questions, and needs, (4) consider strategies for social scientists to contribute to drought management, (5) facilitate coordination among federal and university researchers for future collaborative activities, and (6) develop a typology of drought decision making that captured group insights. Project outputs included two conference sessions, a typology manuscript to be submitted by the end of FY19, and the conceptual framing of a rapid assessment methodology that was subsequently developed into a standalone project.","language":"English","publisher":"National Climate Adaptation Science Center","usgsCitation":"Wilke, A., Cravens, A.E., and O’Malley, R., 2019, Intermountain west drought social science synthesis working group: Report to the National Climate Adaptation Science Center: Cooperator Report, 5 p.","productDescription":"5 p.","ipdsId":"IP-108543","costCenters":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"links":[{"id":375413,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":366336,"type":{"id":15,"text":"Index Page"},"url":"https://cascprojects.org/#/project/5050cb0ee4b0be20bb30eac0/57fe4a93e4b0824b2d143265"}],"publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Wilke, Adam","contributorId":217942,"corporation":false,"usgs":false,"family":"Wilke","given":"Adam","email":"","affiliations":[{"id":24583,"text":"former USGS employee","active":true,"usgs":false}],"preferred":false,"id":767868,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cravens, Amanda E. 0000-0002-0271-7967 aecravens@usgs.gov","orcid":"https://orcid.org/0000-0002-0271-7967","contributorId":196752,"corporation":false,"usgs":true,"family":"Cravens","given":"Amanda","email":"aecravens@usgs.gov","middleInitial":"E.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":true,"id":767867,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"O’Malley, Robin 0000-0002-4211-3316 romalley@usgs.gov","orcid":"https://orcid.org/0000-0002-4211-3316","contributorId":217943,"corporation":false,"usgs":true,"family":"O’Malley","given":"Robin","email":"romalley@usgs.gov","affiliations":[{"id":477,"text":"North Central Climate Science Center","active":true,"usgs":true}],"preferred":true,"id":767869,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Guidelines are given for interpreting curves showing cumulative infiltration as a function of time measured by the autodisc. The autodisc was used to measure the variability of these soil hydraulic properties in three different sample sets: (a) a reference soil consisting of a nonrepellent, uniform, fine sand; (b) soils with the same soil textural classification derived from the same bedrock geology but having different initial burn severities; and (c) soils from different bedrock geology but having the same burn severity. The autodisc infiltrometer had greater sampling rates and volume resolution when compared with the visual minidisc infiltrometer from previous studies. There was no statistical difference in the mean values measured using the autodisc and visual minidisc, but the variability of the autodisc measurements was significantly less than the visual minidisc for a given set of samples. The greatest variability of soil hydraulic properties in reference samples with uniform particle size was attributed to different pore geometries (coefficient of variation [COV] = 0.28–0.34). Unburned field samples (same soil type) with heterogeneous particle sizes had greater variability (COV = 0.57–0.78) than the reference samples. However, this basic variability decreased or remained constant in these field samples as burn severity increased. Additional sources of variability (COV = 0.53–1.99) were attributed to multiple layers resulting from ash or sediment deposition. Results indicate that resolving differences in soil hydraulic properties from different sites requires more than the common 10 random samples because of the multiple sources of variability.</p></div></div>","language":"English","publisher":"Wiley","doi":"10.1002/hyp.13543","usgsCitation":"Moody, J.A., Martin, R., and Ebel, B., 2019, Sources of inherent infiltration variability in postwildfire soils: Hydrological Processes, v. 33, no. 23, p. 3010-3029, https://doi.org/10.1002/hyp.13543.","productDescription":"20 p.","startPage":"3010","endPage":"3029","ipdsId":"IP-099111","costCenters":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"links":[{"id":408879,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"33","issue":"23","noUsgsAuthors":false,"publicationDate":"2019-09-11","publicationStatus":"PW","contributors":{"authors":[{"text":"Moody, John A. 0000-0003-2609-364X jamoody@usgs.gov","orcid":"https://orcid.org/0000-0003-2609-364X","contributorId":771,"corporation":false,"usgs":true,"family":"Moody","given":"John","email":"jamoody@usgs.gov","middleInitial":"A.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":856137,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Martin, Richard G.","contributorId":195347,"corporation":false,"usgs":false,"family":"Martin","given":"Richard G.","affiliations":[],"preferred":false,"id":856138,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ebel, Brian A. 0000-0002-5413-3963","orcid":"https://orcid.org/0000-0002-5413-3963","contributorId":211845,"corporation":false,"usgs":true,"family":"Ebel","given":"Brian A.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":856139,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The transect of NADP stations (sites) was used to collect continuous precipitation depth and weekly wet-deposition samples in the Denver – Boulder, Colorado urban corridor.  Gradients in reactive inorganic nitrogen (Nr) concentrations and wet deposition were identified along the transect, which included Rocky Mountain National Park. Back trajectory modeling and stable isotopes suggested contribution of agricultural ammonia (NH3) to urban Nr wet deposition in Denver, but apportionment of wet-deposited Nr to agricultural versus urban mobile sources was not possible for this study.  The results demonstrate the importance of multiple monitoring sites across an urban area in defining fine-scale geographic patterns in atmospheric deposition and its sources.  Data from new sites located within 50 km of the urban area demonstrate that the urban influence doesn't extend as far as the Inverse Distance Weighting would have suggested without such empirical monitoring data.

Wetlands may be particularly susceptible to altered flow regimes as they are directly impacted by water flows at a variety of time scales. In Puerto Rico, contemporary water management is decreasing freshwater recharge to wetlands and contributes to the salinization of important coastal wetlands as sea levels rise. Further, downscaled climate models predict an increase in drought frequency, intensity, and duration by mid-century. Conflicts over water allocation seem imminent between human and ecological needs. Current minimum flow policies are insufficient given the complexities of ecosystem processes and the changes in precipitation patterns and sea level rise that are expected in the future. Improved flow policies need to be established that reflect the functional relationships between specific representative ecological resources and components of the natural flow regime across all relevant time scales. Similarly, flow policies need to be developed within a landscape scale to implicitly address the socio-ecological trade-offs as well as the complexities of water management. Multi-disciplinary collaborations will be essential for increasing our resiliency to anticipated future changes.","language":"English","publisher":"Society of Wetland Scientists","doi":"10.1007/s13157-019-01184-5","usgsCitation":"Murry, B., Bowden, J., Branoff, B., Garcia-Bermudez, M., Middleton, B., Ortiz-Zayas, J., Restrepo, C., and Terando, A., 2019, Perspective: Developing flow policies to balance the water needs of humans and wetlands requires a landscape scale approach inclusive of future scenarios and multiple timescales: Wetlands, p. 1-13, https://doi.org/10.1007/s13157-019-01184-5.","productDescription":"13 p.","startPage":"1","endPage":"13","ipdsId":"IP-104897","costCenters":[{"id":565,"text":"Southeast Climate Science Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"links":[{"id":365483,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"publishingServiceCenter":{"id":5,"text":"Lafayette PSC"},"noUsgsAuthors":false,"publicationDate":"2019-07-02","publicationStatus":"PW","contributors":{"authors":[{"text":"Murry, Brent","contributorId":216870,"corporation":false,"usgs":false,"family":"Murry","given":"Brent","affiliations":[{"id":39538,"text":"USFWS Science Applications, San Juan Puerto Rico","active":true,"usgs":false}],"preferred":false,"id":765942,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bowden, Jared","contributorId":197528,"corporation":false,"usgs":false,"family":"Bowden","given":"Jared","affiliations":[],"preferred":false,"id":765943,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Branoff, Benjamin","contributorId":216871,"corporation":false,"usgs":false,"family":"Branoff","given":"Benjamin","affiliations":[{"id":39539,"text":"University of Puerto Rico, San Juan, PR","active":true,"usgs":false}],"preferred":false,"id":765944,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Garcia-Bermudez, Miguel","contributorId":216872,"corporation":false,"usgs":false,"family":"Garcia-Bermudez","given":"Miguel","affiliations":[{"id":39540,"text":"USFWS Science Applications, San Juan, PR","active":true,"usgs":false}],"preferred":false,"id":765945,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Middleton, Beth A. 0000-0002-1220-2326","orcid":"https://orcid.org/0000-0002-1220-2326","contributorId":216869,"corporation":false,"usgs":true,"family":"Middleton","given":"Beth","middleInitial":"A.","affiliations":[{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":765941,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Ortiz-Zayas, Jorge","contributorId":216873,"corporation":false,"usgs":false,"family":"Ortiz-Zayas","given":"Jorge","email":"","affiliations":[{"id":39539,"text":"University of Puerto Rico, San Juan, PR","active":true,"usgs":false}],"preferred":false,"id":765946,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Restrepo, Carla","contributorId":216874,"corporation":false,"usgs":false,"family":"Restrepo","given":"Carla","email":"","affiliations":[{"id":39541,"text":"University of Puerto Rico, San Juan PR","active":true,"usgs":false}],"preferred":false,"id":765947,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Terando, Adam J. 0000-0002-9280-043X","orcid":"https://orcid.org/0000-0002-9280-043X","contributorId":216875,"corporation":false,"usgs":true,"family":"Terando","given":"Adam J.","affiliations":[{"id":565,"text":"Southeast Climate Science Center","active":true,"usgs":true}],"preferred":true,"id":765948,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

As a result, water quality in many of the streams, lakes, and coastal embayments on Cape Cod is impaired by excess nitrogen. To reduce nitrogen loads to these impaired water bodies, watershed-based planning is currently [2019] underway following a regional strategy, the section 208 areawide water-quality management plan update for Cape Cod. In the updated plan, traditional (sewering) and alternative wastewater management options are under consideration for restoring water quality in impaired surface-water bodies. Permeable reactive barriers, which are reactive zones emplaced below the water table for passive treatment of groundwater contaminants, are one of the alternatives being considered by Cape Cod towns as a potentially cost-effective technology for the removal of nitrogen from groundwater. However, the effectiveness of permeable reactive barriers depends on local conditions, and site-specific hydrologic and water-quality data are needed to inform the decision to install a permeable reactive barrier in a given location. These data are not available in most locations on Cape Cod; consequently, site assessments are needed before selecting this treatment option.</p><p>To address this need, the U.S. Environmental Protection Agency, U.S. Geological Survey, and Cape Cod Commission formed a technical team in 2015 to develop and evaluate a hydrologic site-assessment approach for permeable reactive barrier installation. The approach developed by the technical team includes a preliminary regional assessment followed by a phased onsite investigation. The approach was intended to provide the hydrologic data needed to make informed decisions on site suitability and to support installation and monitoring should the site be deemed appropriate for a permeable reactive barrier. The factors that were evaluated to characterize local hydrologic conditions and inform site selection included groundwater flow directions and rates, depth to the water table, hydraulic conductivity and degree of heterogeneity of the aquifer, spatial distribution and concentration of nitrate and oxidation-reduction-sensitive constituents, thickness and depth of the treatment zone, distance to downgradient water bodies, and access for drilling and permeable reactive barrier installation. The approach was demonstrated on Cape Cod by conducting a preliminary assessment of 27 sites, from which 5 sites were selected for onsite investigations. Results indicated that the site-assessment approach was successful for screening sites and characterizing the geologic, hydrologic, and water-quality conditions at the sites selected for onsite investigations. Overall, the phased assessment evaluated in this study provided an efficient means of obtaining the hydrologic information needed to determine if a site was suitable for permeable reactive barrier installation on Cape Cod for the passive treatment of nitrogen in groundwater.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston,

We present 1,456 new fission track ages and 1,372 new U‐Pb ages from double‐dated detrital zircons derived from fourteen samples collected from offshore. We integrate our results with published geochronology and thermochronology data onland and offshore in order to constrain grain provenance. We find that offshore strata deposited east of the fold and thrust belt are sourced from the rapidly exhuming areas along the entire Fairweather Fault, the northeastern part of the syntaxial region, as well as the slowly exhuming Insular superterrane. In contrast, the western strata are sourced from the emerging fold and thrust belt and the Chugach Metamorphic Complex located north of the plate boundary. In these samples we identified a change in sediment provenance, which we suggest marks the capture of the Bagley Ice Valley by the proto‐Bering Glacier at the transition from the early to late Pliocene. This implies that the modern Bagley‐Bering Glacier System is much older than previously known. Strata deposited at ~8.6 Ma suggest that extreme rapid exhumation was already ongoing in the late Miocene, which supports previous findings in deep‐sea deposits. Overall, the data help discern several stages in the evolution of sediment routing patterns in response to dynamic tectonic and surficial processes along this active convergent margin.</p></div>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2019TC005497","usgsCitation":"Bootes, N., Enkelmann, E., and Lease, R.O., 2019, Late Miocene to Pleistocene source to sink record of exhumation and sediment routing in the Gulf of Alaska from detrital zircon fission-track and U-Pb double dating: Tectonics, v. 38, no. 8, p. 2703-2726, https://doi.org/10.1029/2019TC005497.","productDescription":"23 p.","startPage":"2703","endPage":"2726","ipdsId":"IP-104877","costCenters":[{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true}],"links":[{"id":378355,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Gulf of Alaska","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -156.005859375,\n              58.07787626787517\n            ],\n            [\n              -138.779296875,\n              58.07787626787517\n            ],\n            [\n              -138.779296875,\n              62.91523303947614\n            ],\n            [\n              -156.005859375,\n              62.91523303947614\n            ],\n            [\n              -156.005859375,\n              58.07787626787517\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"38","issue":"8","noUsgsAuthors":false,"publicationDate":"2019-08-05","publicationStatus":"PW","contributors":{"authors":[{"text":"Bootes, Nathaniel","contributorId":240603,"corporation":false,"usgs":false,"family":"Bootes","given":"Nathaniel","email":"","affiliations":[{"id":7159,"text":"University of Cincinnati","active":true,"usgs":false}],"preferred":false,"id":798541,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Enkelmann, Eva","contributorId":240604,"corporation":false,"usgs":false,"family":"Enkelmann","given":"Eva","email":"","affiliations":[{"id":16660,"text":"University of Calgary","active":true,"usgs":false}],"preferred":false,"id":798542,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lease, Richard O. 0000-0003-2582-8966 rlease@usgs.gov","orcid":"https://orcid.org/0000-0003-2582-8966","contributorId":5098,"corporation":false,"usgs":true,"family":"Lease","given":"Richard","email":"rlease@usgs.gov","middleInitial":"O.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":119,"text":"Alaska Science Center Geology Minerals","active":true,"usgs":true}],"preferred":true,"id":798543,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Transient crustal motions have been observed following numerous magnitude &gt;~7 earthquakes in various&nbsp;tectonic settings: continental&nbsp;rift zones&nbsp;(Basin and Range), continental&nbsp;plate boundary&nbsp;zones (San Andreas fault corridor; Alaska; Turkey),&nbsp;subduction zones&nbsp;(Japan, Chile, Sumatra), ongoing&nbsp;continental collision&nbsp;zones (Arabia; Tibet), and mid-ocean rifting zones (Iceland). When afterslip can be discriminated from viscoelastic relaxation and when temporal coverage of the postseismic measurements is broad (i.e.,&nbsp;geodetic surveys&nbsp;of at least several years duration are available), a wide spectrum of relaxation timescales are usually identified. Current temporal resolution and modeling approaches (e.g., Burgers body analog) allow identification of transient (Kelvin) and steady-state (Maxwell) viscosities that are operable in the short-term and long-term, respectively. I compile results from 40 studies of post-earthquake motions, augmented by ten studies of contemporary surface loading or unloading, that illuminate current estimates of transient and steady-state viscosity of the lower crust and/or uppermost mantle. Lower crust viscosity estimates range from&nbsp;</span><i>~</i><span>10</span><sup>18</sup><span>&nbsp;to 10</span><sup>21</sup><span>&nbsp;Pa s, with most estimates near the upper end except in areas of overthickened crust.

Though this dynamic behavior has been previously incorporated into soil carbon respiration modeling frameworks, a direct comparison between this active-dormant transition mechanism and a more simplified first-order model has yet to be made. Here, we demonstrate the necessary extent of model complexity needed to reproduce transient carbon respiration rates obtained from a set of soil incubation experiments implemented over a range of soil depths and time intervals. Two approaches are tested, one uses simplified first-order kinetics whereas the other employs a transition between active and dormant biomass. The performance of each model is evaluated using an Akaike Information Criterion (AIC) based on the accuracy with which they reproduce an experimental dataset consisting of two sets of time series soil incubations collected across a range of time and depth resolutions. Based on the AIC evaluation and model-data comparison, we conclude that a dormancy-enabled model featuring two distinct microbial strategists performs best for the majority of the soil profile (above 108 cm) for both high- and low- depth resolution and sampling frequency, despite the added parameters required. In contrast, the first-order model achieves better AIC scores when simulating our deepest soils (112-165 cm), where moisture fluctuations are expected to be less prevalent. These results guide how and where we choose to apply more cost intensive models.","language":"English","doi":"10.1029/2018JG004628","usgsCitation":"Liu, Y., Lawrence, C.R., Mathew Winnick, Hsiao-Tieh Hsu, Maher, K., and Druhan, J., 2019, Modeling transient soil moisture limitations on microbial carbon respiration: A cost-performance comparison: Biogeosciences, v. 124, no. 7, p. 2222-2247, https://doi.org/10.1029/2018JG004628.","productDescription":"26 p.","startPage":"2222","endPage":"2247","ipdsId":"IP-091717","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":467487,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2018jg004628","text":"Publisher Index Page"},{"id":367761,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"124","issue":"7","publishingServiceCenter":{"id":2,"text":"Denver PSC"},"noUsgsAuthors":false,"publicationDate":"2019-07-22","publicationStatus":"PW","contributors":{"authors":[{"text":"Liu, Yuchen","contributorId":219247,"corporation":false,"usgs":false,"family":"Liu","given":"Yuchen","email":"","affiliations":[{"id":39974,"text":"University Illinois","active":true,"usgs":false}],"preferred":false,"id":771792,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lawrence, Corey R. 0000-0001-6143-7781","orcid":"https://orcid.org/0000-0001-6143-7781","contributorId":202390,"corporation":false,"usgs":true,"family":"Lawrence","given":"Corey","email":"","middleInitial":"R.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":771793,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mathew Winnick","contributorId":219248,"corporation":false,"usgs":false,"family":"Mathew Winnick","affiliations":[{"id":36396,"text":"University of Massachusetts","active":true,"usgs":false}],"preferred":false,"id":771794,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hsiao-Tieh Hsu","contributorId":219249,"corporation":false,"usgs":false,"family":"Hsiao-Tieh Hsu","affiliations":[{"id":6986,"text":"Stanford University","active":true,"usgs":false}],"preferred":false,"id":771795,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Maher, Katherine","contributorId":219250,"corporation":false,"usgs":false,"family":"Maher","given":"Katherine","email":"","affiliations":[{"id":6986,"text":"Stanford University","active":true,"usgs":false}],"preferred":false,"id":771796,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Druhan, Jennifer","contributorId":202381,"corporation":false,"usgs":false,"family":"Druhan","given":"Jennifer","email":"","affiliations":[{"id":36403,"text":"University of Illinois","active":true,"usgs":false}],"preferred":false,"id":771797,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Hydroacoustic eruption signals were observed on the regional Mariana seismic network and on distant hydrophones, and NOAA scuba divers working in the area soon after the eruption began heard and felt underwater explosion sounds. The NOAA crew observed yellow orange bubble mats along the shore of neighboring Farallon de Pájaros island, but no other surface manifestations of the eruption were reported by the crew or observed in satellite data. Here, we detail the eruption chronology and its morphologic impacts through analysis of seismic and hydroacoustic recordings and repeat bathymetric mapping. Throughout the 2-week-long eruption, Ahyi produced several thousand short, impulsive hydroacoustic signals that we interpret as underwater explosions as well as tremor near the beginning and end of the sequence. The initial tremor, which occurred for 2 hours, is interpreted as small phreatomagmatic explosions. This tremor was followed by a 90 min pause before the characteristic impulsive signals began. Occasional tremor (lasting up to a few minutes) during the last 1.5 days of the eruption is interpreted as more sustained eruptive activity. Bathymetric changes show that a new crater, about 150 m deep, formed near the former summit and a large landslide chute formed on the southeastern flank. Comparing to other geophysically-detected submarine eruptions, we find that the signals from the 2014 Ahyi eruption were more similar to those from other shallow or at surface submarine eruptions than those at deep (>500 m) eruptions.","language":"English","publisher":"Wiley","doi":"10.1029/2019GC008311","usgsCitation":"Tepp, G., Chadwick, W.W., Haney, M.M., Lyons, J.J., Robert Dziak, Merle, S., Butterfield, D., and Young, C.W., 2019, Hydroacoustic, seismic, and bathymetric observations of the 2014 submarine eruption at Ahyi Seamount, Mariana Arc: Geochemistry, Geophysics, Geosystems, v. 20, no. 7, p. 3608-3627, https://doi.org/10.1029/2019GC008311.","productDescription":"10 p.","startPage":"3608","endPage":"3627","ipdsId":"IP-105686","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":366024,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"20","issue":"7","publishingServiceCenter":{"id":14,"text":"Menlo Park PSC"},"noUsgsAuthors":false,"publicationDate":"2019-07-26","publicationStatus":"PW","contributors":{"authors":[{"text":"Tepp, Gabrielle 0000-0001-5388-5138","orcid":"https://orcid.org/0000-0001-5388-5138","contributorId":206305,"corporation":false,"usgs":true,"family":"Tepp","given":"Gabrielle","email":"","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":767266,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Chadwick, William W.","contributorId":216757,"corporation":false,"usgs":false,"family":"Chadwick","given":"William","email":"","middleInitial":"W.","affiliations":[{"id":39510,"text":"NOAA/CIMRS","active":true,"usgs":false}],"preferred":false,"id":767267,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Haney, Matthew M. 0000-0003-3317-7884 mhaney@usgs.gov","orcid":"https://orcid.org/0000-0003-3317-7884","contributorId":172948,"corporation":false,"usgs":true,"family":"Haney","given":"Matthew","email":"mhaney@usgs.gov","middleInitial":"M.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"preferred":true,"id":767268,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Lyons, John J. 0000-0001-5409-1698 jlyons@usgs.gov","orcid":"https://orcid.org/0000-0001-5409-1698","contributorId":5394,"corporation":false,"usgs":true,"family":"Lyons","given":"John","email":"jlyons@usgs.gov","middleInitial":"J.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"preferred":true,"id":767269,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Robert Dziak","contributorId":217675,"corporation":false,"usgs":false,"family":"Robert Dziak","affiliations":[{"id":39567,"text":"NOAA/PMEL","active":true,"usgs":false}],"preferred":false,"id":767270,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Merle, Susan","contributorId":217676,"corporation":false,"usgs":false,"family":"Merle","given":"Susan","email":"","affiliations":[{"id":39568,"text":"Oregon State University/CIMRS","active":true,"usgs":false}],"preferred":false,"id":767271,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Butterfield, Dave","contributorId":217677,"corporation":false,"usgs":false,"family":"Butterfield","given":"Dave","email":"","affiliations":[{"id":39682,"text":"University of Washington/JISAO","active":true,"usgs":false}],"preferred":false,"id":767272,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Young, Charles W.","contributorId":217678,"corporation":false,"usgs":false,"family":"Young","given":"Charles","email":"","middleInitial":"W.","affiliations":[{"id":39683,"text":"NOAA/PIFSC","active":true,"usgs":false}],"preferred":false,"id":767273,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Despite recent declines, nitrogen and sulfur deposition continue to affect many plant communities in the United States, although which species are at risk remains uncertain. We used species composition data from >14,000 survey sites across the contiguous United States to evaluate the association between nitrogen and sulfur deposition and the probability of occurrence for 348 herbaceous species. We found that the probability of occurrence for 70% of species was negatively associated with nitrogen or sulfur deposition somewhere in the contiguous United States (56% for N, 51% for S). Of the species, 15% and 51% potentially decreased at all nitrogen and sulfur deposition rates, respectively, suggesting thresholds below the minimum deposition they receive. Although more species potentially increased than decreased with nitrogen deposition, increasers tended to be introduced and decreasers tended to be higher-value native species. More vulnerable species tended to be shorter with lower tissue nitrogen and magnesium. These relationships constitute predictive equations to estimate critical loads. These results demonstrate that many herbaceous species may be at risk from atmospheric deposition and can inform improvements to air quality policies in the United States and globally.","language":"English","publisher":"Springer Nature Limited","doi":"10.1038/s41477-019-0442-8","usgsCitation":"Clark, C.M., Simkin, S.M., Allen, E.B., Bowman, W., Belnap, J., Brooks, M.L.,

To investigate the eastern boundary of the prairie-forest ecotone, we conducted a case study of historic and modern vegetation patterns of the Yellow River watershed in northwest Indiana. Historic vegetation came from the Public Land Survey notes collected in the early 1800s, whereas modern vegetation came from the Forest Inventory Analysis and USGS National Land Cover Database. We mapped historical survey vegetation data using GIS to reconstruct the region’s past and current forest composition and structure. We also mapped climate, topography, and soil composition across the watershed to investigate the relationship between historic vegetation and environmental gradients. We found a sharp transition in the presettlement forest structure and composition, with dense deciduous forests in the eastern portion of our study area and open oak savannas in the west. The savanna ecosystem dominated in sandy well-drained soils and was at a slightly lower elevation than the adjacent closed forest. Modest environmental changes accompanied major vegetation changes in the past, which might suggest fire and hydrological patterns helped maintain the sharp ecotone. By contrast, the modern forest shows no difference in tree density and composition across the watershed, which is consistent with major land use and hydrology changes in the watershed since settlement. On the modern landscape, land that was historically closed forest now has higher agricultural productivity compared to land that was historically savanna, whereas the historic savanna currently supports more mesic forest. These results suggest the environmental gradient continues to subtly shape the landscape. Though land use change has largely removed the closed mixed hardwood forests and oak savannas from this area, a better understanding of the historic vegetation and the conditions that supported it can help inform land management and restoration, as well as reveal ecological processes that drive vegetation transitions.","language":"English","publisher":"BioOne","doi":"10.1674/0003-0031-180.1.1","usgsCitation":"Broderick, C.M., Heilman, K.A., Patterson, T., Peters, J., and McLachlan, J.S., 2019, Sharp savanna-forest transitions in the Midwest followed environmental gradients but are absent from the modern landscape: The American Midland Naturalist, v. 180, no. 1, p. 1-17, https://doi.org/10.1674/0003-0031-180.1.1.","productDescription":"17","startPage":"1","endPage":"17","ipdsId":"IP-086114","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":365314,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Indiana","otherGeospatial":"Yellow River Watershed Area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -86.84005737304688,\n              41.24683746537623\n            ],\n            [\n              -86.38412475585938,\n              41.24683746537623\n            ],\n            [\n              -86.38412475585938,\n              41.422134246213616\n            ],\n            [\n              -86.84005737304688,\n              41.422134246213616\n            ],\n            [\n              -86.84005737304688,\n              41.24683746537623\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"180","issue":"1","publishingServiceCenter":{"id":15,"text":"Madison PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Broderick, Caitlin M.","contributorId":216788,"corporation":false,"usgs":false,"family":"Broderick","given":"Caitlin","email":"","middleInitial":"M.","affiliations":[{"id":39516,"text":"University of Notre Dame","active":true,"usgs":false}],"preferred":false,"id":765533,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Heilman, Kelly A 0000-0001-5932-1317","orcid":"https://orcid.org/0000-0001-5932-1317","contributorId":216789,"corporation":false,"usgs":false,"family":"Heilman","given":"Kelly","email":"","middleInitial":"A","affiliations":[{"id":39516,"text":"University of Notre Dame","active":true,"usgs":false}],"preferred":false,"id":765534,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Patterson, Tamatha 0000-0002-1648-8114 tpatterson@usgs.gov","orcid":"https://orcid.org/0000-0002-1648-8114","contributorId":201149,"corporation":false,"usgs":true,"family":"Patterson","given":"Tamatha","email":"tpatterson@usgs.gov","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":765532,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Peters, Jody","contributorId":216790,"corporation":false,"usgs":false,"family":"Peters","given":"Jody","affiliations":[{"id":39516,"text":"University of Notre Dame","active":true,"usgs":false}],"preferred":false,"id":765535,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"McLachlan, Jason S.","contributorId":167179,"corporation":false,"usgs":false,"family":"McLachlan","given":"Jason","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":765536,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

These methods have underrepresented concentrations of suspended sediment in rivers compared to U.S. Geological Survey equal-width increment or equal-discharge-increment (EWDI) field sampling and suspended-sediment concentration (SSC) laboratory analysis methods. Because of this underrepresentation, the U.S. Geological Survey, in collaboration with the Minnesota Pollution Control Agency, collected concurrent grab and EWDI samples at eight sites to compare results obtained using different combinations of field sampling and laboratory analysis methods. Study results determined that grab field sampling and TSS laboratory analysis results were biased substantially low compared to EWDI sampling and SSC laboratory analysis results, respectively. Differences in both field sampling and laboratory analysis methods caused grab and TSS methods to be biased substantially low. The difference in laboratory analysis methods was slightly greater than field sampling methods. Sand-sized particles had a strong effect on the comparability of the field sampling and laboratory analysis methods. These results indicated that grab field sampling and TSS laboratory analysis methods fail to capture most of the sand being transported by the stream. The results indicate there is less of a difference among samples collected with grab field sampling and analyzed for TSS and concentration of fines in SSC. Even though differences are present, the presence of strong correlations between SSC and TSS concentrations provides the opportunity to develop site specific relations to address transport processes not captured by grab field sampling and TSS laboratory analysis methods.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of SEDHYD

Point bars are composed of sediment layers in patterns resulting from the rate and style of channel migration, hydrodynamics, and sediment transport and deposition within the river system (e.g. Jackson, 1976; Dietrich and Smith, 1984; Dietrich, 1987, Abad and Garcia, 2009). The distribution of the sediments preserved in the internal architecture of a river point bar provides a record of channel planform evolution. Geophysical methods are used to gain a large-scale visualization of the subsurface and aid in the interpretation of historic channel patterns (Best et al., 2003; Woodward et al., 2003; Sambrook Smith et al., 2006). Comparing known surficial extents of the point bar to features identified in the subsurface can also enhance the understanding of historic channel planform. This study investigates two point bars along bends with different styles of migration, Maier and TB3, in a well-documented reach of the Wabash River near Grayville, IL. Evidence from historic aerial photography, modern lidar, photogrammetry, and geophysical surveys were used to determine the relationship between the point bar architecture and channel planform. Airborne lidar was flown in 2011 and is used to create the 2011 point bar surface. In 2017, a terrestrial lidar and Real Time Kinematic-Global Navigation Satellite System (RTK-GNSS) topographic survey were combined to create the surface for TB3. In 2018, a photogrammetric survey collected with a small unmanned aerial system (sUAS) was used to create a structure-frommotion (SfM) derived surface for Maier bend. The 2018 survey-based point bar surfaces were differenced from the 2011 point bar surfaces to get a Digital Elevation Model (DEM) of difference (DoD) to visualize areas of erosion and deposition. In addition, geophysical surveys using ground penetrating radar (GPR) were conducted in transverse and streamwise lines across the point bars in 2018. Elevation profiles from the 2011 point bar surfaces are extracted and overlain onto the 2018 GPR images to determine how the point bar is preserving the structure of sediments previously deposited. Results from this study provide an update to current models of point bar architecture. </p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of SEDHYD 2019","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"SEDHYD 2019 Conference","conferenceDate":"June 24-28, 2019","conferenceLocation":"Reno, NV","language":"English","publisher":"Federal Interagency Sedimentation Conference (FISC) and Federal Interagency Hydrologic Modeling Conference (FIHMC)","usgsCitation":"Rowley, T., Konsoer, K., Ursic, M., and Langendoen, E.J., 2019, The relationship of channel planform and point bar architecture on a reach of the Wabash River near Grayville, Illinois, <i>in</i> Proceedings of SEDHYD 2019, v. 1, Reno, NV, June 24-28, 2019, 5 p.","productDescription":"5 p.","ipdsId":"IP-104932","costCenters":[{"id":24708,"text":"Lower Mississippi-Gulf Water Science Center","active":true,"usgs":true}],"links":[{"id":368663,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":368662,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.sedhyd.org/2019/#sedhyd-2019-proceedings"}],"country":"United States","state":"Illinois","city":"Grayville","otherGeospatial":"Wabash River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -87.95722961425781,\n              38.25476238074633\n            ],\n            [\n              -87.901611328125,\n              38.25476238074633\n            ],\n            [\n              -87.901611328125,\n              38.30920107060575\n            ],\n            [\n              -87.95722961425781,\n              38.30920107060575\n            ],\n            [\n              -87.95722961425781,\n              38.25476238074633\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"1","publishingServiceCenter":{"id":5,"text":"Lafayette PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Rowley, Taylor 0000-0003-3786-6273","orcid":"https://orcid.org/0000-0003-3786-6273","contributorId":208374,"corporation":false,"usgs":true,"family":"Rowley","given":"Taylor","email":"","affiliations":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true},{"id":24708,"text":"Lower Mississippi-Gulf Water Science Center","active":true,"usgs":true}],"preferred":true,"id":759117,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Konsoer, Kory","contributorId":220049,"corporation":false,"usgs":false,"family":"Konsoer","given":"Kory","email":"","affiliations":[],"preferred":false,"id":773986,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ursic, Mick","contributorId":220050,"corporation":false,"usgs":false,"family":"Ursic","given":"Mick","email":"","affiliations":[],"preferred":false,"id":773987,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Langendoen, Eddy J.","contributorId":66126,"corporation":false,"usgs":true,"family":"Langendoen","given":"Eddy","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":773988,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Without snowpack to buffer the hydrologic response, the storm caused widespread landslides and debris flows in drainages sourced from every central Cascades volcano. At Mount St. Helens, in southwestern Washington State, intense rainfall in the crater of the volcano caused at least two mass failures with an aggregate volume of 4.5 million m3, which spawned a series of debris flows with velocities as great as 11 m/s. The debris flows incised Loowit Creek as much as 9 m and traveled 16 river km before transforming to hyperconcentrated flow via rapid dilution at the confluence of North Fork Toutle River (NFT), Castle Creek, and Maratta Creek (Figure 1). Reduced channel gradient downstream lowered velocity enough to transform to sediment-laden streamflow less than 40 km from the source, where suspended-sediment concentration (SSC) peaked at 177,000 mg/L. Heavy rain persisted for several days, producing over 100 cm of rainfall in upper NFT basin which caused immediate remobilization of surface deposits; half of the annual suspended-sediment discharge (SSQ) for water year (WY) 2007 was transported in 5 days, despite a relatively low 7-year flood recurrence interval.

Data collected during the flush was used to validate a one-dimensional sediment transport model developed by the USACE. The USACE surveyed 26 cross sections within the reservoir and as far as 1 kilometer (km) upstream from the reservoir pool to about 10 km downstream from the dam before and after the flushing event to measure erosion and deposition. They also collected surficial sediment samples from sandbars within the reservoir. The USGS assisted USACE in its model validation efforts by collecting sediment data before, during and after the flush using both traditional sampling techniques and a continuous laser-diffraction particle-size analyzer. From the context of longitudinal volumetric change, the model replicated erosion in the upper half of the reservoir within four percent of that observed by survey data and it replicated deposition downstream of the dam within 5 percent. However, the model underpredicted the erosion of the accumulated delta sediments in the reservoir by 43 percent. The timing and magnitude of suspended sediment concentrations produced by the model compared reasonably well to the discrete suspended-sediment sample results. These results indicate cross-sectional survey data and discrete sediment data may be adequate for developing sediment flush models for reservoirs in similar well-sorted sand-bed streams.\n\nThe USGS installed a continuous particle-size analyzer immediately downstream from the dam. Although the particle-size analyzer was successful in providing a large dataset during the flushing event, based on discrete point samples, it overestimated the amount of fine particles and underrepresented the amount of coarse material. It also required a significant amount of maintenance during the flushing event because of the large sediment load and the rapid bed aggradation. The maintenance issues with the particle-size analyzer along with uncertainty in the correlation to discrete suspended-sediment samples reduced its value for model validation. However, these issues may have been specific to the flushing event at Spencer Dam, which involved a sand-bed dominated stream and a wide channel. It is foreseeable that other sediment flush models developed for different streams with dissimilar sediment gradations may benefit from similar continuous sediment data, but adequate planning and evaluation should be performed.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of SEDHYD 2019","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"SEDHYD 2019 Conference","conferenceDate":"June 24-28, 2019","conferenceLocation":"Reno, NV","language":"English","publisher":"Federal Interagency Sedimentation Conference (FISC) and Federal Interagency Hydrologic Modeling Conference (FIHMC)","usgsCitation":"Schaepe, N.J., and Boyd, P.M., 2019, Sediment monitoring to support modeling a reservoir sediment flush on a sand-bed river in Northern Nebraska, <i>in</i> Proceedings of SEDHYD 2019, v. 2, Reno, NV, June 24-28, 2019, 14 p.","productDescription":"14 p.","ipdsId":"IP-105260","costCenters":[{"id":464,"text":"Nebraska Water Science Center","active":true,"usgs":true}],"links":[{"id":368654,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://www.sedhyd.org/2019/#sedhyd-2019-proceedings"},{"id":368655,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Nebraska","city":"Spencer","otherGeospatial":"Niobara River, Spencer Dam","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -98.68452072143555,\n              42.79514872764227\n            ],\n            [\n              -98.61997604370117,\n              42.79514872764227\n            ],\n            [\n              -98.61997604370117,\n              42.81391436163743\n            ],\n            [\n              -98.68452072143555,\n              42.81391436163743\n            ],\n            [\n              -98.68452072143555,\n              42.79514872764227\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"2","publishingServiceCenter":{"id":4,"text":"Rolla PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Schaepe, Nathaniel J. 0000-0003-1776-7411 nschaepe@usgs.gov","orcid":"https://orcid.org/0000-0003-1776-7411","contributorId":2377,"corporation":false,"usgs":true,"family":"Schaepe","given":"Nathaniel","email":"nschaepe@usgs.gov","middleInitial":"J.","affiliations":[{"id":464,"text":"Nebraska Water Science Center","active":true,"usgs":true}],"preferred":true,"id":761566,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Boyd, Paul M","contributorId":215066,"corporation":false,"usgs":false,"family":"Boyd","given":"Paul","email":"","middleInitial":"M","affiliations":[{"id":590,"text":"U.S. Army Corps of Engineers","active":false,"usgs":false}],"preferred":false,"id":761567,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Episodic rainfalls feed very large winter floods, but dry summer and fall periods lead to extensive dry alluvial reaches due to surface water infiltration into subsurface aquifers. Within one of these dry reaches, a small inset channel has developed to effectively convey year-round wastewater discharges. This flow creates a coarse bed substrate composed of gravel and cobble that is home for diatoms and algae, the diet for the Santa Ana Sucker, a threatened native fish. \n\nField-based observations include:\n•\tShear stresses in the inset channel are capable of transporting sand as bedload, but not gravel and cobble. Bedload measurements (at several locations and times under wastewater discharge conditions) indicate that about 90% of the bedload is sand. The median grain size of bedload samples is consistently in the 0.5–1-mm range with little longitudinal variability.\n\n•\tThe upstream supply of sand decreases through time as winnowing proceeds in the downstream direction. Bedload transport rates increase in the downstream direction by an order of magnitude over just 7 km, despite the fact that water discharge decreases downstream due to infiltration (typically by 25–50% over the 7-km reach). \n\n•\tThe location of the gravel-to-sand bed transition is variable from year to year and is related to the amount of time that has elapsed since the most recent upstream runoff event. These events supply new sediment to the reach and reset the winnowing process.\n\n•\tDirect observations of the inset channel following upstream runoff events revealed many instances of large areas of substantial sand deposition in the channel, in areas that were previously entirely gravel and cobble sizes.\n\nWe propose a qualitative function to predict the bed substrate of the inset channel at any given time and location. A one-dimensional model of bedload transport and bed substrate in the study reach is being developed to quantify and test the predictive function. Preliminary results indicate that the winnowing process is quite sensitive to wastewater discharge levels. The calibrated model will be used to assess how treatment plant discharge scenarios might be used to strategically manage winnowing rates and the amount of gravel and cobble exposed on the bed in the reach.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Proceedings of SEDHYD 2019","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"SEDHYD 2019 Conference","conferenceDate":"June 24-28, 2019","conferenceLocation":"Reno, NV","language":"English","publisher":"Federal Interagency Sedimentation Conference (FISC) and Federal Interagency Hydrologic Modeling Conference (FIHMC)","usgsCitation":"Wright, S., and Minear, J.T., 2019, Field-scale sediment feed flume: Upper Santa Ana River, California, <i>in</i> Proceedings of SEDHYD 2019, v. 1, Reno, NV, June 24-28, 2019, 2 p.","productDescription":"2 p.","ipdsId":"IP-107058","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":363507,"type":{"id":15,"text":"Index Page"},"url":"https://www.sedhyd.org/2019/#sedhyd-2019-proceedings"},{"id":368653,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"Upper Santa Ana River Valley","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.44178771972656,\n              33.965572781967936\n            ],\n            [\n              -117.24128723144531,\n              33.965572781967936\n            ],\n            [\n              -117.24128723144531,\n              34.11407854333859\n            ],\n            [\n              -117.44178771972656,\n              34.11407854333859\n            ],\n            [\n              -117.44178771972656,\n              33.965572781967936\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"1","publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Wright, Scott 0000-0002-0387-5713 sawright@usgs.gov","orcid":"https://orcid.org/0000-0002-0387-5713","contributorId":1536,"corporation":false,"usgs":true,"family":"Wright","given":"Scott","email":"sawright@usgs.gov","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":762154,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Minear, J.

CRREL operates a custom airborne lidar system that can be deployed in a helicopter-based pod (HeliPod). Data were collected with the HeliPod near existing USGS streamflow information stations on the Knik, Matanuska, Chena, and Salcha Rivers in both 2017 and 2018. Sites on the Tanana and Snow Rivers were added in 2018. In 2018, the HeliPod was modified to accommodate both a thermal infrared and a visible camera. The cameras were integrated with the flight management software to simultaneously acquire imagery with lidar. The Global Navigation Satellite System (GNSS) and inertial measurement unit (IMU) in the HeliPod were used to compute trajectories with precise position and orientation information needed for image orthorectification. The HeliPod sensors provide data for measuring river channel characteristics. Lidar can map the elevation of the water surface and thus be used to measure water-surface slopes and return intensity can be used to delineate the extent of the wetted river channel. Various approaches are currently being evaluated to estimate surface flow velocity from visible and thermal image time series. In this paper, we examine and compare water-surface elevation returns and slopes derived from the HeliPod lidar and found good agreement with measurements made using conventional field-based techniques.","conferenceTitle":"Federal Interagency Sedimentation and Hydrologic Modeling Conference (SEDHYD 2019)","conferenceDate":"June 24-28, 2019","conferenceLocation":"Reno, Nevada","language":"English","publisher":"Federal Interagency Sedimentation and Hydrologic Modeling Conference (SEDHYD 2019)","usgsCitation":"Kinzel, P.J., Legleiter, C.J., Nelson, J.M., Conaway, J., LeWinter, A., Gadomski, P., and Filiano, D., 2019, Near-field remote sensing of Alaskan Rivers, Federal Interagency Sedimentation and Hydrologic Modeling Conference (SEDHYD 2019), Reno, Nevada, June 24-28, 2019, 10 p.","productDescription":"10 p.","ipdsId":"IP-106032","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true},{"id":5044,"text":"National Research Program -
