Important multiphase processes include the transport of gases, nonaqueous liquids, and solid particles. Numerous means are available for determination of unsaturated conditions and properties, both measurement (of moisture state, water retention, and dynamic characteristics) and through various formulas and models that are mostly empirical in nature, but in some cases incorporating insight into unsaturated‐zone physical processes. Applications to practical problems include models and techniques relating to distributions of water and energy, fluxes at the land surface, inputs, outputs, and fluxes within the unsaturated zone, all of which are frequently complicated by heterogeneity and preferential flow. Further scientific advance requires new measurement techniques and theoretical constructs that more adequately represent the important physical processes within practical modeling schemes.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Encyclopedia of hydrological sciences, part 13, groundwater","language":"English","publisher":"Wiley","publisherLocation":"Chichester","doi":"10.1002/0470848944.hsa161","usgsCitation":"Nimmo, J.R., 2005, Unsaturated zone flow processes, chap. <i>of</i> Encyclopedia of hydrological sciences, part 13, groundwater, v. 4, p. 2299-2322, https://doi.org/10.1002/0470848944.hsa161.","productDescription":"24 p.","startPage":"2299","endPage":"2322","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":356771,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4","noUsgsAuthors":false,"publicationDate":"2006-04-15","publicationStatus":"PW","scienceBaseUri":"5b98c7c3e4b0702d0e8465d0","contributors":{"authors":[{"text":"Nimmo, John R. 0000-0001-8191-1727 jrnimmo@usgs.gov","orcid":"https://orcid.org/0000-0001-8191-1727","contributorId":757,"corporation":false,"usgs":true,"family":"Nimmo","given":"John","email":"jrnimmo@usgs.gov","middleInitial":"R.","affiliations":[{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true},{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":743504,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Nitrite or iron(III) oxyhydroxides may oxidize U(IV) under nitrate-reducing conditions, and we determined the rate and extent of U(IV) oxidation by these compounds. Fe(III) oxidized U(IV) at a greater rate than nitrite (130 and 10 μM U(IV)/day, respectively). In aquifer sediments, Fe(III) may be produced during microbial nitrate reduction by oxidation of Fe(II) with nitrite, or by enzymatic Fe(II) oxidation coupled to nitrate reduction. To determine which of these mechanisms was dominant, we isolated a nitrate-dependent acetate- and Fe(II)-oxidizing bacterium from a U(VI)- and nitrate-contaminated aquifer. This organism oxidized U(IV) at a greater rate and to a greater extent under acetate-oxidizing (where nitrite accumulated to 50 mM) than under Fe(II)-oxidizing conditions. We show that the observed differences in rate and extent of U(IV) oxidation are due to mineralogical differences between Fe(III) produced by reaction of Fe(II) with nitrite (amorphous) and Fe(III) produced enzymatically (goethite or lepidocrocite).

Unifying concepts are needed to better tie together such complexities. Here we suggest that a biologically based conceptualization, the biodynamic model, provides the necessary unification for a key aspect in risk:  metal bioaccumulation (internal exposure). The model is mechanistically based, but empirically considers geochemical influences, biological differences, and differences among metals. Forecasts from the model agree closely with observations from nature, validating its basic assumptions. The biodynamic metal bioaccumulation model combines targeted, high-quality geochemical analyses from a site of interest with parametrization of key physiological constants for a species from that site. The physiological parameters include metal influx rates from water, influx rates from food, rate constants of loss, and growth rates (when high). We compiled results from 15 publications that forecast species-specific bioaccumulation, and compare the forecasts to bioaccumulation data from the field. These data consider concentrations that cover 7 orders of magnitude. They include 7 metals and 14 species of animals from 3 phyla and 11 marine, estuarine, and freshwater environments. The coefficient of determination (</span><i>R</i><sup>2</sup><span>) between forecasts and independently observed bioaccumulation from the field was 0.98. Most forecasts agreed with observations within 2-fold. The agreement suggests that the basic assumptions of the biodynamic model are tenable.

For this latter reason, their management and long-term fate has many interfaces with environmental microbial communities and processes. The interactions of microorganisms with UMT have been shown to be diverse and with significant consequences for radionuclide mobility and bioremediation. These radionuclides are associated with the U-decay series. The addition of organic carbon and phosphate is required to initiate the reduction of the U present in the groundwater down gradient of the mills. Investigations on sediment and water from the U-contaminated aquifer, indicates that the addition of a carbon source stimulates the rate of U removal by microbial reduction. Moreover, most attention with respect to passive or engineered removal of U from groundwaters focuses on iron-reducing and sulfate-reducing bacteria.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/S0065-2164(05)57004-7","usgsCitation":"Landa, E.R., 2005, Microbial biogeochemistry of uranium mill tailings: Advances in Applied Microbiology, v. 57, p. 113-130, https://doi.org/10.1016/S0065-2164(05)57004-7.","productDescription":"18 p.

While the US population grew by 37% between the 1970 and 2000 censuses, the growth for Albuquerque was 83%. More people mean more development and increased problems of managing runoff from urbanizing watersheds. The U.S. Geological Survey (USGS) in cooperation with the Albuquerque Arroyo Metropolitan Flood Control Authority (AMAFCA) and the City of Albuquerque has maintained a rainfall-runoff data collection program since 1976. The data from measured precipitation events can be used to verify hydrologic modeling. In this presentation, data from a representative gaged watershed is analyzed and discussed to set the overall framework for the rainfall-runoff process in the Albuquerque area. Of particular interest are the basic relationships between rainfall and watershed runoff response and an analysis of curve numbers as an indicator of runoff function. In urbanized areas, four land treatment types (natural, irrigated lawns, compacted soil, and impervious) are used to define surface infiltration conditions. Rainfall and runoff gage data are used to compare curve number (CN) and initial abstraction/uniform infiltration (IA/INF) techniques in an Albuquerque watershed. The IA/INF method appears to produce superior results over the CN method for the measured rainfall events.","largerWorkTitle":"Proceedings of the 2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges","conferenceTitle":"2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges","conferenceDate":"19 July 2005 through 22 July 2005","conferenceLocation":"Williamsburg, VA","language":"English","isbn":"0784407630","usgsCitation":"Anderson, C., Ward, T., and Kelly, T., 2005, Rainfall-runoff in the Albuquerque, New Mexico, area: Measurements, analyses and comparisons, <i>in</i> Proceedings of the 2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges, Williamsburg, VA, 19 July 2005 through 22 July 2005, p. 1787-1796.","startPage":"1787","endPage":"1796","numberOfPages":"10","costCenters":[],"links":[{"id":238502,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a947be4b0c8380cd8142c","contributors":{"editors":[{"text":"Moglen G.E.","contributorId":128404,"corporation":true,"usgs":false,"organization":"Moglen G.E.","id":536627,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Anderson, C.E.","contributorId":26511,"corporation":false,"usgs":true,"family":"Anderson","given":"C.E.","email":"","affiliations":[],"preferred":false,"id":414687,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Ward, T.J.","contributorId":17039,"corporation":false,"usgs":true,"family":"Ward","given":"T.J.","email":"","affiliations":[],"preferred":false,"id":414686,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kelly, T.","contributorId":29993,"corporation":false,"usgs":true,"family":"Kelly","given":"T.","affiliations":[],"preferred":false,"id":414688,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We examined controls on microbially mediated nitrate-dependent U(IV) oxidation in landfill leachate-impacted subsurface sediments. Nitrate-dependent U(IV)-oxidizing bacteria were at least two orders of magnitude less numerous in these sediments than glucose- or Fe(II)-oxidizing nitrate-reducing bacteria and grew more slowly than the latter organisms, suggesting that U(IV) is ultimately oxidized by Fe(III) produced by nitrate-dependent Fe(II)-oxidizing bacteria or by oxidation of Fe(II) by nitrite that accumulates during organotrophic dissimilatory nitrate reduction. We examined the effect of nitrate and reductant concentration on nitrate-dependent U(IV) oxidation in sediment incubations and used the initial reductive capacity (RDC = [reducing equivalents] - [oxidizing equivalents]) of the incubations as a unified measurement of the nitrate or reductant concentration. When we lowered the RDC with progressively higher nitrate concentrations, we observed a corresponding increase in the extent of U(IV) oxidation, but did not observe this relationship between RDC and U(IV) oxidation rate, especially when RDC &gt; 0, suggesting that nitrate concentration strongly controls the extent, but not the rate of nitrate-dependent U(IV) oxidation. On the other hand, when we raised the RDC in sediment incubations with progressively higher reductant (acetate, sulfide, soluble Fe(II), or FeS) concentrations, we observed progressively lower extents and rates of nitrate-dependent U(IV) oxidation. Acetate was a relatively poor inhibitor of nitrate-dependent U(IV) oxidation, while Fe(II) was the most effective inhibitor. Based on these results, we propose that it may be possible to predict the stability of U(IV) in a bioremediated aquifer based on the geochemical characteristics of that aquifer.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/01490450500248911","usgsCitation":"Senko, J.M., Suflita, J.M., and Krumholz, L.R., 2005, Geochemical controls on microbial nitrate-dependent U(IV) oxidation: Geomicrobiology Journal, v. 22, no. 7-8, p. 371-378, https://doi.org/10.1080/01490450500248911.","productDescription":"8 p.

These chemical constituents and their relative abundances are not an equilibrium evaporite assemblage and to a substantial degree have been reworked by aeolian and subaqueous transport. Ultimately they formed by evaporation of acidic waters derived from interaction with olivine-bearing basalts and subsequent diagenetic alteration. The rocks experienced an extended diagenetic history, with at least two and up to four distinct episodes of cementation, including stratigraphically restricted zones of recrystallization and secondary porosity, non-randomly distributed, highly spherical millimeter-scale hematitic concretions, millimeter-scale crystal molds, interpreted to have resulted from dissolution of a highly soluble evaporite mineral, elongate to sheet-like vugs and evidence for minor synsedimentary deformation (convolute and contorted bedding, possible teepee structures or salt ridge features). Other features that may be diagenetic, but more likely are associated with relatively recent meteorite impact, are meter-scale fracture patterns, veins and polygonal fractures on rock surfaces that cut across bedding. Crystallization of minerals that originally filled the molds, early cement and sediment deformation occurred syndepositionally or during early diagenesis. All other diagenetic features are consistent with formation during later diagenesis in the phreatic (fluid saturated) zone or capillary fringe of a groundwater table under near isotropic hydrological conditions such as those expected during periodic groundwater recharge. Textural evidence suggests that rapidly formed hematitic concretions post-date the primary mineral now represented by crystal molds and early pore-filling cements but pre-date secondary moldic and vug porosity. The second generation of cements followed formation of secondary porosity. This paragenetic sequence is consistent with an extended history of syndepositional through post-depositional diagenesis in the presence of a slowly fluctuating, chemically evolving, but persistently high ionic strength groundwater system.</span></p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Earth and Planetary Science Letters","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.epsl.2005.09.041","issn":"0012821X","usgsCitation":"McLennan, S.M., Bell, J., Calvin, W.M., Christensen, P.R., Clark, B.C., de Souza, P., Farmer, J., Farrand, W.H., Fike, D., Gellert, R., Ghosh, A., Glotch, T., Grotzinger, J., Hahn, B., Herkenhoff, K.E., Hurowitz, J., Johnson, J.R., Johnson, S., Jolliff, B., Klingelhofer, G., Knoll, A., Learner, Z., Malin, M.C., McSween, H., Pocock, J., Ruff, S.W., Soderblom, L.A., Squyres, S.W., Tosca, N., Watters, W., Wyatt, M., and Yen, A., 2005, Provenance and diagenesis of the evaporite-bearing Burns formation, Meridiani Planum, Mars: Earth and Planetary Science Letters, v. 240, no. 1, p. 95-121, https://doi.org/10.1016/j.epsl.2005.09.041.","productDescription":"27 p.","startPage":"95","endPage":"121","numberOfPages":"27","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":238422,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Burns formation; Mars; Meridiani Planum","volume":"240","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a8f9de4b0c8380cd7f882","contributors":{"authors":[{"text":"McLennan, S.

The dam is located near Purvis, Mississippi, on Bay Creek, which flows into Lower Little Creek about 1.9 miles downstream from the dam. Lower Little Creek flows into Pearl River about 16.9 miles downstream from the dam. Knowledge of the hydrology and hydraulics of floods caused by dam breaks is essential to the design of dams. A better understanding of the risks associated with possible dam failures may help limit the loss of life and property that often occurs downstream of a dam failure. The USGS recovered flood marks at the one crossing of Bay Creek and eight crossings of Lower Little Creek. Additional flood marks were also flagged at three other bridges crossing tributaries where backwater occurred. Flood marks were recovered throughout the stream reach of about 3/4 to 15 miles downstream of the dam. Flood marks that were flagged will be surveyed so that a flood profile can be documented downstream of the Big Bay Lake dam failure. Peak discharges are also to be estimated where possible. News reports stated that the peak discharge at the dam was about 67,000 cubic feet per second. Preliminary data suggest the peak discharge from the dam failure attenuated to about 13,000 cubic feet per second at Lower Little Creek at State Highway 43, about 15 miles downstream of the dam.","largerWorkTitle":"Proceedings of the 2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges","conferenceTitle":"2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges","conferenceDate":"19 July 2005 through 22 July 2005","conferenceLocation":"Williamsburg, VA","language":"English","isbn":"0784407630","usgsCitation":"Van Wilson, K., 2005, Data collection and documentation of flooding downstream of a dam failure in Mississippi, <i>in</i> Proceedings of the 2005 Watershed Management Conference - Managing Watersheds for Human and Natural Impacts: Engineering, Ecological, and Economic Challenges, Williamsburg, VA, 19 July 2005 through 22 July 2005.","startPage":"1277","costCenters":[],"links":[{"id":238092,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fd6ee4b0c8380cd4e81f","contributors":{"editors":[{"text":"Moglen G.E.","contributorId":128404,"corporation":true,"usgs":false,"organization":"Moglen G.E.","id":536622,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Van Wilson, K.

The framework includes seven distinct hydrogeologic subregions within which the primary natural physical factors affecting the flow and chemistry of shallow ground water and small streams are relatively consistent. Within most subregions, the transport of chemicals from the land surface to ground water and streams can be described by a fairly uniform set of natural processes; some subregions include mixed hydrogeologic settings that are indistinguishable at the regional scale. The hydrogeologic framework and accompanying physiographic and geologic delineations are presented in digital and printed format.</p><p>The seven hydrogeologic subregions that constitute the framework were delineated primarily on the basis of physiography and the predominant texture (typical grain size) of surficial and (where surficial sediments are particularly thin) subcropping sediments. Physiography for the Mid-Atlantic Coastal Plain was constructed by standardizing and extrapolating previously published interpretations for the Coastal Plain of South Carolina and New Jersey, based on similar work in the other States. Surficial and subcropping geology were similarly compiled from previous publications by resolving inconsistencies in nomenclature, interpretation, and scale, and interpolating across unmapped areas. A bulk sediment texture was determined for each mapped geologic unit on the basis of published descriptions.</p><p>Fundamental differences among the seven hydrogeologic subregions are described on the basis of hypotheses about surficial and shallow subsurface hydrology and water chemistry in each, as well as variable land use, soils, and topography. On the regional scale, the Coastal Lowlands (Subregion 1), the Middle Coastal Plain - Fine Sediments (Subregion 3), the Middle Coastal Plain - Sands with Overlying Gravels (Subregion 4), and the Inner Coastal Plain - Upland Sands and Gravels (Subregion 5) are relatively homogeneous in terms of hydrogeology, although an examination of results from small-scale studies within the Coastal Plain demonstrates that even these areas are quite variable, locally. Moderate topographic relief and primarily permeable surficial sediments promote good drainage of the land surface in Subregion 4, for example, but drainage is commonly poor in the Coastal Lowlands (Subregion 1) due to flat topography and low elevations. Agriculture is common in both subregions, although artificial drainage is typically required to support cultivation in Subregion 1. Important physiographic differences are evident among the remaining three subregions, although sediment textures within the Middle Coastal Plain - Mixed Sediment Texture (Subregion 2), the Inner Coastal Plain - Dissected Outcrop Belt (Subregion 6), and the Alluvial and Estuarine Valleys (Subregion 7) are variable even at the regional scale.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/pp1680","isbn":"0607957461","usgsCitation":"Ator, S.W., Denver, J., Krantz, D.E., Newell, W., and Martucci, S.K., 2005, A surficial hydrogeologic framework for the Mid-Atlantic Coastal Plain: U.S. Geological Survey Professional Paper 1680, vi, 44 p., https://doi.org/10.3133/pp1680.","productDescription":"vi, 44 p.","costCenters":[{"id":41514,"text":"Maryland-Delaware-District of Columbia  Water Science Center","active":true,"usgs":true}],"links":[{"id":87128,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/pp/1680/report.pdf","text":"Report","linkFileType":{"id":1,"text":"pdf"},"description":"PP 1680"},{"id":174235,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/pp/1680/report-thumb.jpg"},{"id":398352,"rank":2,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_83500.htm"}],"country":"United States","state":"Delaware, Maryland, New Jersey, North Carolina, Virginia","otherGeospatial":"Mid-Atlantic Coastal Plain","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -80.1123046875,\n              35.02999636902566\n            ],\n            [\n              -78.1787109375,\n              33.687781758439364\n            ],\n            [\n              -76.3330078125,\n              34.84987503195418\n            ],\n            [\n              -75.7177734375,\n              36.4566360115962\n            ],\n            [\n              -75.0146484375,\n              38.89103282648846\n            ],\n            [\n              -74.00390625,\n              40.413496049701955\n            ],\n            [\n              -74.3994140625,\n              40.74725696280421\n            ],\n            [\n              -75.9375,\n              39.605688178320804\n            ],\n            [\n              -76.552734375,\n              39.50404070558415\n            ],\n            [\n              -77.0361328125,\n              38.238180119798635\n            ],\n            [\n              -77.2998046875,\n              37.3002752813443\n            ],\n            [\n              -77.3876953125,\n              35.71083783530009\n            ],\n            [\n              -79.9365234375,\n              34.994003757575776\n            ],\n            [\n              -80.1123046875,\n              35.02999636902566\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","contact":"<p><a href=\"mailto:dc_md@usgs.gov\" data-mce-href=\"mailto:dc_md@usgs.gov\">Director</a>, <a href=\"https://www.usgs.gov/centers/md-de-dc-water\" data-mce-href=\"https://www.usgs.gov/centers/md-de-dc-water\">MD-DE-DC Water Science Center</a><br>U.S. Geological Survey<br>522 Research Park Drive<br>Catonsville, MD 21228</p>","tableOfContents":"<ul><li>Foreword</li><li>Abstract</li><li>Introduction</li><li>Development of the regional surficial hydrogeologic framework</li><li>The regional surficial hydrogeologic framework</li><li>Evaluation of the regional framework at the local scale</li><li>Framework application</li><li>Summary</li><li>References</li><li>Appendix 1.
