The approach is Bayesian, combining the reliable records of hurricane activity during the twentieth century with the less precise accounts of activity during the nineteenth century to produce a best estimate of the posterior distribution on the annual rates. The methodology provides a predictive distribution of future activity that serves as a climatological benchmark. Results are presented for the entire coast as well as for the Gulf Coast, Florida, and the East Coast. Statistics on the observed annual counts of U.S. hurricanes, both for the entire coast and by region, are similar within each of the three consecutive 50-yr periods beginning in 1851. However, evidence indicates that the records during the nineteenth century are less precise. Bayesian theory provides a rational approach for defining hurricane climate that uses all available information and that makes no assumption about whether the 150-yr record of hurricanes has been adequately or uniformly monitored. The analysis shows that the number of major hurricanes expected to reach the U.S. coast over the next 30 yr is 18 and the number of hurricanes expected to hit Florida is 20.</p>","language":"English","publisher":"American Meteorological Society","usgsCitation":"Elsner, J.B., and Bossak, B.H., 2001, Bayesian analysis of U.S. hurricane climate: Journal of Climate, v. 14, no. 23, p. 4341-4350.","productDescription":"10 p.","startPage":"4341","endPage":"4350","costCenters":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":337658,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":337657,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://journals.ametsoc.org/toc/clim/14/23"}],"country":"United States","volume":"14","issue":"23","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58ca52ffe4b0849ce97c8750","contributors":{"authors":[{"text":"Elsner, James B.","contributorId":189356,"corporation":false,"usgs":false,"family":"Elsner","given":"James","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":684574,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bossak, Brian H.","contributorId":10112,"corporation":false,"usgs":true,"family":"Bossak","given":"Brian","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":684575,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The objective of this particular study was to improve our understanding\nof the effects of different river discharges and lake levels of Coeur d'Alene Lake on the transport of cadmium, zinc, and lead within the main stem Coeur d'Alene River. In particular, water-quality data and loads during a broad range of hydrologic conditions were examined to determine if the river channel, flood plain, and associated ground water along the main stem Coeur d'Alene River acted as sources or sinks of trace elements. Water-quality samples were collected at six riverine stations and one lake station along a 35-mile reach during March, June, September, and October of 1999. Samples were analyzed for whole-water recoverable, filtered (0.45 micrometer), and dissolved (0.01 micrometer) concentrations of cadmium, zinc, and lead. Concentrations and loads of cadmium and zinc measured during the four sampling trips were predominately in the filtered and dissolved fraction ,rather than particulate. The smallest concentrations were measured during the June sampling trip when flows were high and snowmelt runoff diluted riverine concentrations. Conversely, the largest concentrations were measured during the latter two sampling trips when flows were low because a larger proportion of the river's discharge was contributed by ground-water inflow. During each sampling trip, cadmium and zinc concentrations generally decreased in a downstream directioeven as discharge increased in a downstream direction. Spatial and temporal trends exhibited by lead concentrations and loads during the four sampling trips were different from those of cadmium and zinc because of the propensity for lead to adsorb to sediment particles. Whole-water recoverable lead concentrations and loads during the four sampling trips were predominantly in the particulate fraction, with filtered and dissolved concentrations and loads composing a much smaller proportion of the recoverable fraction compared to cadmium and zinc. Filtered lead concentrations generally increased at a faster rate in the downstream direction than dissolved lead concentrations; thus, colloidallead either was being formed by complexation reactions or being added by sediment erosion in the downstream direction.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr0134","collaboration":"Prepared in cooperation with U.S. Environmental Protection Agency","usgsCitation":"Woods, P.F., 2001, Concentrations and loads of cadmium, zinc, and lead in the main stem Coeur d'Alene River, Idaho&mdash;March, June, September, and October 1999: U.S. Geological Survey Open-File Report 2001-34, iv, 33 p., https://doi.org/10.3133/ofr0134.","productDescription":"iv, 33 p.","numberOfPages":"39","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":262352,"rank":800,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0034/report.pdf"},{"id":262353,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2001/0034/report-thumb.jpg"}],"country":"United States","state":"Idaho","city":"Coeur D'alene;Cataldo;Harrison","otherGeospatial":"Coeur D'alene Lake;Rose Lake;Post Falls Dam","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.0464,47.1971 ], [ -117.0464,47.9819 ], [ -115.995,47.9819 ], [ -115.995,47.1971 ], [ -117.0464,47.1971 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b16e4b07f02db6a5605","contributors":{"authors":[{"text":"Woods, P.

The program was designed by the U.S. Geological Survey and the Massachusetts Department of Environmental Protection, Division of Watershed Management, with input from many organizations involved in water-quality monitoring in the State, and focuses on inland surface waters (streams and lakes). The proposed monitoring program consists of several components, or tiers, which are defined in terms of specific monitoring objectives, and is intended to complement the Massachusetts Watershed Initiative (MWI) basin assessments. Several components were developed using the Neponset River Basin in eastern Massachusetts as a pilot area, or otherwise make use of data from and sampling approaches used in that basin as part of a MWI pilot assessment in 1994. To guide development of the monitoring program, reviews were conducted of general principles of network design, including monitoring objectives and approaches, and of ongoing monitoring activities of Massachusetts State agencies.Network tiers described in this report are primarily (1) a statewide, basin-based assessment of existing surface-water-quality conditions, and (2) a fixed-station network for determining contaminant loads carried by major rivers. Other components, including (3) targeted programs for hot-spot monitoring and other objectives, and (4) compliance monitoring, also are discussed. Monitoring programs for the development of Total Maximum Daily Loads for specific water bodies, which would constitute another tier of the network, are being developed separately and are not described in this report. The basin-based assessment of existing conditions is designed to provide information on the status of surface waters with respect to State water-quality standards and designated uses in accordance with the reporting requirements [Section 305(b)] of the Clean Water Act (CWA). Geographic Information System (GIS)-based procedures were developed to inventory streams and lakes in a basin for these purposes. Several monitoring approaches for this tier and their associated resource requirements were investigated. Analysis of the Neponset Basin for this purpose demonstrated that the large number of sites needed in order for all the small streams in a basin to be sampled (about half of stream miles in the basin were headwater or first-order streams) pose substantial resource-based problems for a comprehensive assessment of existing conditions. The many lakes pose similar problems. Thus, a design is presented in which probabilistic monitoring of small streams is combined with deterministic or targeted monitoring of large streams and lakes to meet CWA requirements and to provide data for other information needs of Massachusetts regulatory agencies and MWI teams.The fixed-station network is designed to permit the determination of contaminant loads carried by the State's major rivers to sensitive inland and coastal receiving waters and across State boundaries. Sampling at 19 proposed sites in 17 of the 27 major basins in Massachusetts would provide information on contaminant loads from 67 percent of the total land area of the State; unsampled areas are primarily coastal areas drained by many small streams that would be impossible to sample within realistic resource limitations. Strategies for hot-spot monitoring, a targeted monitoring program focused on identifying contaminant sources, are described with reference to an analysis of the bacteria sampling program of the 1994 Neponset Basin assessment. Finally, major discharge sites permitted under the National Pollutant Discharge Elimination System (NPDES) were evaluated as a basis for ambient water-quality monitoring. The discharge sites are well distributed geographically among basins, but are primarily on large rivers (two-thirds or more ","language":"ENGLISH","doi":"10.3133/wri014081","usgsCitation":"DeSimone, L.A., Steeves, P.A., and Zimmerman, M., 2001, Statewide water-quality network for Massachusetts: U.S. Geological Survey Water-Resources Investigations Report 2001-4081, 88 p., https://doi.org/10.3133/wri014081.","productDescription":"88 p.","costCenters":[],"links":[{"id":160301,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":2883,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri014081","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a07e4b07f02db5f9909","contributors":{"authors":[{"text":"DeSimone, Leslie A. 0000-0003-0774-9607 ldesimon@usgs.gov","orcid":"https://orcid.org/0000-0003-0774-9607","contributorId":195635,"corporation":false,"usgs":true,"family":"DeSimone","given":"Leslie","email":"ldesimon@usgs.gov","middleInitial":"A.","affiliations":[{"id":466,"text":"New England Water Science Center","active":true,"usgs":true},{"id":376,"text":"Massachusetts Water Science Center","active":true,"usgs":true}],"preferred":true,"id":204361,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Steeves, Peter A. 0000-0001-7558-9719 psteeves@usgs.gov","orcid":"https://orcid.org/0000-0001-7558-9719","contributorId":1873,"corporation":false,"usgs":true,"family":"Steeves","given":"Peter","email":"psteeves@usgs.gov","middleInitial":"A.","affiliations":[{"id":41514,"text":"Maryland-Delaware-District of Columbia  Water Science Center","active":true,"usgs":true}],"preferred":true,"id":204360,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Zimmerman, Marc James","contributorId":104888,"corporation":false,"usgs":true,"family":"Zimmerman","given":"Marc James","affiliations":[],"preferred":false,"id":204362,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The U.S. Geological Survey designed and operated a streamflow and water quality\nmonitoring network in the basin during the 1999 water year (October 1, 1998, through September 30, 1999) in support of this Remedial Investigation/Feasibility Study. The objective for\nthe network was to quantify the absolute and relative magnitude of hydrologic, trace-element, and nutrient loads transported by numerous stream reaches within the Spokane River Basin. Of the 29 water-quality stations in the network, 19 were in the Coeur d?Alene River Basin, 2 were in the St. Joe River Basin, and the remaining 8 were on the Spokane River downstream from Coeur d'Alene Lake. All stations were sampled for whole-water recoverable and dissolved concentrations of cadmium, lead, and zinc. Nitrogen and phosphorus concentrations were sampled at nine stations to determine loads of nutrients into and out of Coeur d'Alene Lake and transported down the Spokane River into the Columbia River. Mean daily discharge during the 1999 water year was about 120 percent of the long-term average. Trace-element loads to the Columbia River were calculated for the basin's terminal station, Spokane River at Long Lake. For whole-water recoverable cadmium, 2,110 pounds, 92 percent of which was dissolved, was delivered to the Columbia River. The Columbia River received 25,000 pounds of whole-water recoverable lead, 29 percent of which was dissolved, from the Spokane River Basin. The largest trace-element load delivered to the Columbia River by the Spokane River was 764,000 pounds of whole-water recoverable zinc, 76 percent of which was dissolved. The primary source of trace-element loads in the Spokane River Basin was the Coeur d'Alene River Basin. The South Fork Coeur d'Alene River was the largest source of dissolved and wholewater recoverable loads of cadmium and zinc. In contrast, the main stem of the Coeur d'Alene River was the largest source of dissolved and wholewater recoverable loads of lead. Within the South Fork, substantial increases in dissolved loads of cadmium, lead, and zinc were detected in excess of those measured by the monitoring network stations upstream from the terminal station, South Fork Coeur d'Alene River near Pinehurst. Much of the added load was attributed to inflow of traceelement-contaminated ground water. Similarly, increases in whole-water recoverable loads of cadmium, lead, and zinc were detected in the South Fork in excess of measured loads; these were attributed largely to erosion and transport of sediment-associated trace elements during increased stream discharge events. Coeur d'Alene Lake received nearly all its trace-element loads from the Coeur d'Alene River. The lake retained the majority of the dissolved and whole-water recoverable loads of lead input to it, but retained almost none of its dissolved and whole-water recoverable loads of zinc. About one-half of the dissolved and whole-water recoverable loads of cadmium was retained in the lake. Within the Spokane River Basin, the largest loads of total nitrogen, 13,000,000 pounds, and total phosphorus, 677,000 pounds, were measuredat Spokane River at Long Lake, the station closest to the Columbia River. At Coeur d'Alene Lake, total nitrogen loads input to the lake from the Coeur d'Alene and St. Joe Rivers totaled 1,890,000 pounds; the lake discharged 2,430,000 pounds. The lake received 253,000 pounds of total phosphorus and discharged 187,000 pounds; thus, 66,000 pounds was retained by the lake.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr00441","collaboration":"Prepared in cooperation with U.S. Environmental Protection Agency","usgsCitation":"Woods, P.F., 2001, Concentrations and loads of cadmium, lead, zinc, and nutrients measured during the 1999 water year within the Spokane River basin, Idaho and Washington: U.S. Geological Survey Open-File Report 2000-441, iv, 32 p., https://doi.org/10.3133/ofr00441.","productDescription":"iv, 32 p.","numberOfPages":"38","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":262350,"rank":800,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2000/0441/report.pdf"},{"id":262351,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2000/0441/report-thumb.jpg"}],"country":"United States","state":"Idaho","otherGeospatial":"Coeur D'alene River Basin;St. Joe River Basin;Coeur D'alene Lake;Long Lake","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -118.4966,46.753 ], [ -118.4966,47.9947 ], [ -114.9876,47.9947 ], [ -114.9876,46.753 ], [ -118.4966,46.753 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b16e4b07f02db6a55d6","contributors":{"authors":[{"text":"Woods, P.

U.S. Geological Survey studies dating from 1975 to 1996 used these data to identify temporal changes of water levels in wells, regional potentiometric surfaces, and the direction of regional ground-water flow in southern Nevada. In the current study, the ground-water potentiometric surface in a 20,000-square-mile section of the regional carbonate-rock aquifer in southern Nevada and southeastern California was identified based on interpretation of water-level data collected from 1998 through 2000. Also included are hydrographs that were constructed from water-level data collected from 1985 through 2000. The hydrographs and accompanying map provide a generalized picture of water levels in consolidated rocks of the southern portion of the carbonate-rock province.

The quadrangle, situated in Joshua Tree National Park in the eastern Transverse Ranges physiographic and structural province, encompasses parts of the Hexie Mountains, Cottonwood Mountains, northern Eagle Mountains, and south flank of Pinto Basin. It is underlain by a basement terrane comprising Proterozoic metamorphic rocks, Mesozoic plutonic rocks, and Mesozoic and Mesozoic or Cenozoic hypabyssal dikes. The basement terrane is capped by a widespread Tertiary erosion surface preserved in remnants in the Eagle and Cottonwood Mountains and buried beneath Cenozoic deposits in Pinto Basin. Locally, Miocene basalt overlies the erosion surface. A sequence of at least three Quaternary pediments is planed into the north piedmont of the Eagle and Hexie Mountains, each in turn overlain by successively younger residual and alluvial deposits. The Tertiary erosion surface is deformed and broken by north-northwest-trending, high-angle, dip-slip faults and an east-west trending system of high-angle dip- and left-slip faults. East-west trending faults are younger than and perhaps in part coeval with faults of the northwest-trending set. The Porcupine Wash database was created using ARCVIEW and ARC/INFO, which are geographical information system (GIS) software products of Envronmental Systems Research Institute (ESRI). The database consists of the following items: (1) a map coverage showing faults and geologic contacts and units, (2) a separate coverage showing dikes, (3) a coverage showing structural data, (4) a scanned topographic base at a scale of 1:24,000, and (5) attribute tables for geologic units (polygons and regions), contacts (arcs), and site-specific data (points). The database, accompanied by a pamphlet file and this metadata file, also includes the following graphic and text products: (1) A portable document file (.pdf) containing a navigable graphic of the geologic map on a 1:24,000 topographic base. The map is accompanied by a marginal explanation consisting of a Description of Map and Database Units (DMU), a Correlation of Map and Database Units (CMU), and a key to point-and line-symbols. (2) Separate .pdf files of the DMU and CMU, individually. (3) A PostScript graphic-file containing the geologic map on a 1:24,000 topographic base accompanied by the marginal explanation. (4) A pamphlet that describes the database and how to access it. Within the database, geologic contacts , faults, and dikes are represented as lines (arcs), geologic units as polygons and regions, and site-specific data as points. Polygon, arc, and point attribute tables (.pat, .aat, and .pat, respectively) uniquely identify each geologic datum and link it to other tables (.rel) that provide more detailed geologic information.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr0130","usgsCitation":"Powell, R.E., 2001, Geologic map and digital database of the Porcupine Wash 7.5 minute Quadrangle, Riverside County, southern California: U.S. Geological Survey Open-File Report 2001-30, Readme Files, Metadata Files, Pamphlet Files, Pamphlet PDF, Database Files, Files for Viewing and Plotting, https://doi.org/10.3133/ofr0130.","productDescription":"Readme Files, Metadata Files, Pamphlet Files, Pamphlet PDF, Database Files, Files for Viewing and Plotting","additionalOnlineFiles":"Y","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":285889,"rank":6,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr0130.jpg"},{"id":282043,"rank":5,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/of/2001/0030/pwash_readme.txt","linkFileType":{"id":2,"text":"txt"}},{"id":282044,"rank":4,"type":{"id":16,"text":"Metadata"},"url":"https://pubs.usgs.gov/of/2001/0030/pwash_met.html","linkFileType":{"id":5,"text":"html"}},{"id":282063,"rank":3,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0030/","linkFileType":{"id":5,"text":"html"}},{"id":282045,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0030/pdf/pwash_pamph.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":282046,"rank":1,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/2001/0030/pdf/pwash_dmu.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"California","county":"Riverside","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.67,33.4259 ], [ -117.67,34.0799 ], [ -114.4349,34.0799 ], [ -114.4349,33.4259 ], [ -117.67,33.4259 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adee4b07f02db6874e1","contributors":{"authors":[{"text":"Powell, Robert E. 0000-0001-7682-1655 rpowell@usgs.gov","orcid":"https://orcid.org/0000-0001-7682-1655","contributorId":4210,"corporation":false,"usgs":true,"family":"Powell","given":"Robert","email":"rpowell@usgs.gov","middleInitial":"E.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":205332,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The cross sections transect that part of the southern Great Basin that includes Death Valley, the Nevada Test Site, and the potential high-level nuclear waste underground repository at Yucca Mountain. The specific geometric relationships portrayed on the cross sections are discussed in the context of four general sub-regions that have stratigraphic similarities and general consistency of structural style: (1) the Nevada Test Site vicinity; (2) the Spring Mountains, Pahrump Valley and Amargosa Desert region; (3) the Death Valley region; and (4) the area east of the Nevada Test Site. \r\nThe subsurface geologic interpretations portrayed on the cross sections are based on an integration of existing geologic maps, measured stratigraphic sections, published cross sections, well data, and geophysical data and interpretations. The estimated top of pre-Cenozoic rocks in the cross sections is based on inversion of gravity data, but the deeper parts of the sections are based on geologic conceptual models and are more speculative. \r\nThe region transected by the cross sections includes part of the southern Basin and Range Province, the northwest-trending Walker Lane belt, the Death Valley region, and the northern Mojave Desert. The region is structurally complex, where a locally thick Tertiary volcanic and sedimentary section unconformably overlies previously deformed Proterozoic through Paleozoic rocks. All of these rocks have been deformed by complex Neogene ex-tensional normal and strike-slip faults.

Geologic and geophysical data, vertical seepage data from the wetlands, canal discharge data, ground-water-level data, and surface-water-stage data collected during 1995 and 1996 were used as boundary conditions and calibration data for the ground-water flow model and as input for the analytical model. Vertical seepage data indicated that water from the wetlands infiltrated the subsurface, near Levee 30, at rates ranging from 0.033 to 0.266 foot per day when the gates at the control structures along Levee 30 canal were closed. During the same period, stage differences between the wetlands (Water Conservation Area 3B) and Levee 30 canal ranged from 0.11 to 1.27 feet. A layer of low-permeability limestone, located 7 to 10 feet below land surface, restricts vertical flow between the surface water in the wetlands and the ground water. Based on measured water-level data, ground-water flow appears to be generally horizontal, except in the direct vicinity of the canal. The increase in discharge rate along a 2-mile reach of the Levee 30 canal ranged from 9 to 30 cubic feet per second per mile and can be attributed primarily to ground-water inflow. Flow rates in Levee 30 canal were greatest when the gates at the control structures were open. The ground-water flow model data were compared with the measured ground-water heads and vertical seepage from the wetlands. Estimating the horizontal ground-water flow rate beneath Levee 30 was difficult owing to the uncertainty in the horizontal hydraulic conductivity of the main flow zone of the Biscayne aquifer. Measurements of ground-water flows into Levee 30 canal, a substantial component of the water budget, were also uncertain, which lessened the ability to validate the model results. Because of vertical flows near Levee 30 canal and a very low hydraulic gradient east of the canal, a simplified Darcian approach simulated with the ground-water flow model does not accurately estimate the horizontal ground-water flow rate. Horizontal ground-water flow rates simulated with the ground-water flow model (for a 60-foot-deep by 1-foot-wide section of the Biscayne aquifer) ranged from 150 to 450 cubic feet per day west of Levee 30 and from 15 to 170 cubic feet per day east of Levee 30 canal. Vertical seepage from the wetlands, within 500 feet of Levee 30, generally accounted for 10 to 15 percent of the total horizontal flow beneath the levee. Simulated horizontal ground-water flow was highest during the wet season and when the gates at the control structures were open.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri014074","usgsCitation":"Sonenshein, R., 2001, Methods to quantify seepage beneath Levee 30, Miami-Dade County, Florida: U.S. Geological Survey Water-Resources Investigations Report 2001-4074, iv, 36 p., https://doi.org/10.3133/wri014074.","productDescription":"iv, 36 p.","costCenters":[],"links":[{"id":414247,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_42283.htm","linkFileType":{"id":5,"text":"html"}},{"id":160322,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":2881,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri014074/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Florida","county":"Miami-Dad County","otherGeospatial":"Levee 30","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -80.417,\n              25.95\n            ],\n            [\n              -80.5,\n              25.95\n            ],\n            [\n              -80.5,\n              25.758\n            ],\n            [\n              -80.417,\n              25.758\n            ],\n            [\n              -80.417,\n              25.95\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a55e4b07f02db62d22d","contributors":{"authors":[{"text":"Sonenshein, R.S.","contributorId":10415,"corporation":false,"usgs":true,"family":"Sonenshein","given":"R.S.","email":"","affiliations":[],"preferred":false,"id":204353,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The quadrangle, situated in Joshua Tree National Park in the eastern Transverse Ranges physiographic and structural province, encompasses part of the northern Eagle Mountains and part of the south flank of Pinto Basin. It is underlain by a basement terrane comprising Proterozoic metamorphic rocks, Mesozoic plutonic rocks, and Mesozoic and Mesozoic or Cenozoic hypabyssal dikes. The basement terrane is capped by a widespread Tertiary erosion surface preserved in remnants in the Eagle Mountains and buried beneath Cenozoic deposits in Pinto Basin. Locally, Miocene basalt overlies the erosion surface. A sequence of at least three Quaternary pediments is planed into the north piedmont of the Eagle Mountains, each in turn overlain by successively younger residual and alluvial deposits. \r\nThe Tertiary erosion surface is deformed and broken by north-northwest-trending, high-angle, dip-slip faults in the Eagle Mountains and an east-west trending system of high-angle dip- and left-slip faults. In and adjacent to the Conejo Well quadrangle, faults of the northwest-trending set displace Miocene sedimentary rocks and basalt deposited on the Tertiary erosion surface and Pliocene and (or) Pleistocene deposits that accumulated on the oldest pediment. Faults of this system appear to be overlain by Pleistocene deposits that accumulated on younger pediments. East-west trending faults are younger than and perhaps in part coeval with faults of the northwest-trending set. \r\n\r\nThe Conejo Well database was created using ARCVIEW and ARC/INFO, which are geographical information system (GIS) software products of Envronmental Systems Research Institute (ESRI). The database consists of the following items: (1) a map coverage showing faults and geologic contacts and units, (2) a separate coverage showing dikes, (3) a coverage showing structural data, (4) a point coverage containing line ornamentation, and (5) a scanned topographic base at a scale of 1:24,000. The coverages include attribute tables for geologic units (polygons and regions), contacts (arcs), and site-specific data (points). The database, accompanied by a pamphlet file and this metadata file, also includes the following graphic and text products: (1) A portable document file (.pdf) containing a navigable graphic of the geologic map on a 1:24,000 topographic base. The map is accompanied by a marginal explanation consisting of a Description of Map and Database Units (DMU), a Correlation of Map and Database Units (CMU), and a key to point-and line-symbols. (2) Separate .pdf files of the DMU and CMU, individually. (3) A PostScript graphic-file containing the geologic map on a 1:24,000 topographic base accompanied by the marginal explanation. (4) A pamphlet that describes the database and how to access it.

The cornerstone of our effort is to use topographic lidar to acquire pre- and post-storm topography to quantify changes to beaches and dunes. With its rapidity of acquisition and very high density, lidar is revolutionizing the. quantification of storm-induced coastal change. Lidar surveys have been acquired for the East and Gulf coasts to serve as pre-storm baselines. Within a few days of a hurricane landfall anywhere within the study area, the impacted area will be resurveyed to detect changes. For example, during 1999, Hurricane Dennis impacted the northern North Carolina coast. Along a 70-km length of coast between Cape Hatteras and Oregon Inlet, there was large variability in the types of impacts including overwash, dune erosion, dune stability, and even accretion at the base of dunes. These types of impacts were arranged in coherent patterns that repeated along the coast over scales of tens of kilometers. Preliminary results suggest the variability is related to the influence of offshore shoals that induce longshore gradients in wave energy by wave refraction.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Coastal Dynamics '01 : proceedings of the Fourth Conference on Coastal Dynamics, June 11-15, 2001, Lund Sweden","largerWorkSubtype":{"id":12,"text":"Conference publication"},"language":"English","publisher":"American Society of Civil Engineers","usgsCitation":"Sallenger, Krabill, W., Swift, R., and Brock, J., 2001, Quantifying hurricane-induced coastal changes using topographic lidar, <i>in</i> Coastal Dynamics '01 : proceedings of the Fourth Conference on Coastal Dynamics, June 11-15, 2001, Lund Sweden, p. 1007-1016.","productDescription":"10 p.","startPage":"1007","endPage":"1016","costCenters":[{"id":186,"text":"Coastal and Marine Geology Program","active":true,"usgs":true}],"links":[{"id":293566,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":293565,"type":{"id":15,"text":"Index Page"},"url":"https://ascelibrary.org/doi/abs/10.1061/40566%28260%29103"}],"country":"United States","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54101476e4b07ab1cd980acd","contributors":{"authors":[{"text":"Sallenger, Jr.","contributorId":105768,"corporation":false,"usgs":true,"family":"Sallenger","suffix":"Jr.","email":"","affiliations":[],"preferred":false,"id":500444,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Krabill, William","contributorId":69013,"corporation":false,"usgs":true,"family":"Krabill","given":"William","affiliations":[],"preferred":false,"id":500443,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Swift, Robert","contributorId":18280,"corporation":false,"usgs":true,"family":"Swift","given":"Robert","affiliations":[],"preferred":false,"id":500441,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brock, John","contributorId":39011,"corporation":false,"usgs":true,"family":"Brock","given":"John","affiliations":[],"preferred":false,"id":500442,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

It includes an area about the size of the Williston Basin of the north-ern United States and southern Canada (?490,000 square kilome-ters). The province contains one dominant total petroleum system, the Sirte-Zelten, based on geochemical data. The Upper Cretaceous Sirte Shale is the primary hydrocarbon source bed. Reservoirs range in rock type and age from fractured Precam-brian basement, clastic reservoirs in the Cambrian-Ordovician Gargaf sandstones, and Lower Cretaceous Nubian (Sarir) Sand-stone to Paleocene Zelten Formation and Eocene carbonates commonly in the form of bioherms. More than 23 large oil fields (>100 million barrels of oil equivalent) and 16 giant oil fields (>500 million barrels of oil equivalent) occur in the province.\r\nAbstract 1\r\nProduction from both clastic and carbonate onshore reservoirs is associated with well-defined horst blocks related to a triple junc-tion with three arms?an eastern Sarir arm, a northern Sirte arm, and a southwestern Tibesti arm. Stratigraphic traps in combina-tion with these horsts in the Sarir arm are shown as giant fields (for example, Messla and Sarir fields in the southeastern portion of the province). Significant potential is identified in areas marginal\r\nto the horsts, in the deeper grabens and in the offshore area.\r\nFour assessment units are defined in the Sirte Basin prov-ince, two reflecting established clastic and carbonate reservoir areas and two defined as hypothetical units. Of the latter, one is offshore in water depths greater than 200 meters, and the other is onshore where clastic units, mainly of Mesozoic age, may be res-ervoirs for laterally migrating hydrocarbons that were generated in the deep-graben areas.\r\nThe Sirte Basin reflects significant rifting in the Early Cre-taceous and syn-rift sedimentary filling during Cretaceous through Eocene time, and post-rift deposition in the Oligocene and Miocene. Multiple reservoirs are charged largely by verti-cally migrating hydrocarbons along horst block faults from Upper Cretaceous source rocks that occupy structurally low posi-tions in the grabens. Evaporites in the middle Eocene, mostly post-rift, provide an excellent seal for the Sirte-Zelten hydrocarbon\r\nsystem. The offshore part of the Sirte Basin is complex, with subduction occurring to the northeast of the province boundary, which is drawn at the 2,000-meter isobath. Possible petroleum systems may be present in the deep offshore grabens on the Sirte Rise such as those involving Silurian and Eocene rocks; however, potential of these systems remains speculative and was not assessed.","language":"ENGLISH","doi":"10.3133/b2202F","usgsCitation":"Ahlbrandt, T.S., 2001, The Sirte Basin province of Libya; Sirte-Zelten total petroleum system (Version 1.0): U.S. Geological Survey Bulletin 2202, 29 p., https://doi.org/10.3133/b2202F.","productDescription":"29 p.","costCenters":[],"links":[{"id":161338,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":3242,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/bul/b2202-f/","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac6e4b07f02db67a946","contributors":{"authors":[{"text":"Ahlbrandt, Thomas S.","contributorId":57836,"corporation":false,"usgs":true,"family":"Ahlbrandt","given":"Thomas","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":209812,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The U.S. Geological Survey designed and implemented synoptic sampling of a high-flow runoff event at selected water-quality stations during the 1999 water year. The objective was to quantify spatial and temporal differences in constituent concentrations and loads over the ascending and descending limbs of a hydrograph depicting a high-flow runoff event. Discharge and water-quality data were collected during spring 1999 snowmelt runoff (May through early June) at nine water-quality stations, one on the North Fork Coeur d’Alene River and eight on the South Fork Coeur d’Alene River. The nine stations were sam- pled for whole-water recoverable and dissolved concentrations and loads of cadmium, lead, and zinc.\nThe concentrations and loads sampled during the 1999 snowmelt-runoff event represented near-normal conditions, not flood conditions, in that the recurrence interval for discharge near the hydrograph peak was about 2 years. The general trend among the nine stations was an inverse relation between discharge and dissolved concentrations of cadmium, lead, and zinc, and a direct relation between discharge and whole-water recoverable concentrations of these constituents. The smallest loads of dissolved and whole-water recoverable cadmium, lead, and zinc were measured at South Fork Coeur d’Alene River above Deadman Gulch; constituent concentrations at this site were some of the smallest among those sampled, and discharge was also relatively small. The largest loads of dissolved and whole-water recoverable cadmium, lead, and zinc were measured at South Fork Coeur d’Alene River at Pinehurst; constituent concentrations at this site were large and discharge was the second-largest of all the discharge measurements.\nHysteresis effects on concentrations and loads over the ascending and descending limbs of the snowmelt-runoff hydrograph were quite apparent, especially for whole-water recoverable constituents. Hysteresis is present when a property, such as constituent concentration or load, has different values for a given discharge over the ascending and descending limbs of a hydrograph. During this study, loads of whole-water recoverable constituents on the ascending limb were between 1.5 and 3.6 times larger than those mea- sured on the descending limb at nearly equal discharge. In contrast, dissolved constituents showed minimal hysteresis effects.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr00310","isbn":"0094-9140","collaboration":"Prepared in cooperation with U.S. Environmental Protection Agency","usgsCitation":"Woods, P.F., 2001, Concentrations and loads of cadmium, lead, and zinc measured on the ascending and descending limbs of the 1999 snowmelt-runoff hydrographs for nine water-quality stations, Coeur d'Alene River basin, Idaho: U.S. Geological Survey Open-File Report 2000-310, iv, 42 p., https://doi.org/10.3133/ofr00310.","productDescription":"iv, 42 p.","numberOfPages":"48","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":262320,"rank":800,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2000/0310/report.pdf"},{"id":262321,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2000/0310/report-thumb.jpg"}],"scale":"100000","projection":"Albers Equal-Area","country":"United States","state":"Idaho","otherGeospatial":"Bunker Hill Superfund;South Fork","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.4998,47.3499 ], [ -116.4998,47.8014 ], [ -115.4985,47.8014 ], [ -115.4985,47.3499 ], [ -116.4998,47.3499 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db636041","contributors":{"authors":[{"text":"Woods, Paul F.","contributorId":82273,"corporation":false,"usgs":true,"family":"Woods","given":"Paul","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":192779,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Radar logging was conducted in six boreholes using 60-MHz omni-directional electric-dipole antennas and a 60-MHz magnetic-dipole directional receiving antenna.Radar data from five boreholes were interpreted to identify the location, orientation, estimated length, and spatial continuity of planar reflectors present in the logs. The overall quality of the radar data is marginal and ranges from very poor to good. Twenty-seven reflectors were interpreted from the directional radar reflection logs. Although the range of orientation interpreted for the reflectors is large, a significant number of reflectors strike northeast-southwest and east-west to slightly northwest-southeast. Reflectors are moderate to steeply dipping and reflector length ranged from less than 7 m to more than 133 m.Qualitative scores were assigned to each reflector to provide a sense of the spatial continuity of the reflector and the characteristics of the field data relative to an ideal planar reflector (orientation score). The overall orientation scores are low, which reflects the general data quality, but also indicates that the properties of most reflectors depart from the ideal planar case. The low scores are consistent with reflections from fracture zones that contain numerous, closely spaced, sub-parallel fractures.Interpretation of borehole-radar direct-wave velocity and amplitude logs identified several characteristics of the logged boreholes: (1) low-velocity zones correlate with decreased direct-wave amplitude, indicating the presence of fracture zones; (2) direct-wave amplitude increases with depth in three of the boreholes, suggesting an increase in electrical resistivity with depth resulting from changes in mineral assemblage or from a decrease in the specific conductance of ground water; and (3) an increase in primary or secondary porosity and an associated change in mineral assemblage, or decrease in ground water specific conductance, was characterized in two of the boreholes below 300 m.The results of the radar reflection logging indicate that even where data quality is marginal, borehole-radar reflection logging can provide useful information for ground-water characterization studies in fractured rock and insights into the nature and extent of fractures and fracture zones in and near boreholes.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri014014","usgsCitation":"Lane, J., Joesten, P., Pohll, G., and Mihevic, T., 2001, Analysis of borehole-radar reflection logs from selected HC boreholes at the Project Shoal area, Churchill County, Nevada: U.S. Geological Survey Water-Resources Investigations Report 2001-4014, iv, 23 p. , https://doi.org/10.3133/wri014014.","productDescription":"iv, 23 p.

Low-flow characteristics are summarized in this report for 67 continuous-record gaging stations and 121 partial-record measuring sites in the Cape Fear River Basin of North Carolina. Records of discharge collected through the 1998 water year were used in the analyses. Flow characteristics included in the summary are (1) average annual unit flow; (2) 7Q10 low-flow discharge, the minimum average discharge for a 7-consecutive-day period occurring, on average, once in 10 years; (3) 30Q2 low-flow discharge; (4) W7Q10 low-flow discharge, similar to 7Q10 discharge except that only flow during November through March is considered; and (5) 7Q2 low-flow discharge.\r\n\r\nLow-flow characteristics in the Cape Fear River Basin vary widely in response to changes in geology and soil types. The area of the basin with the lowest potentials for sustained base flows is underlain by the Triassic basin in parts of Durham, Wake, and Chatham Counties. Typically, these soils are derived from basalt and fine-grained sedimentary rocks that allow very little infiltration of water into the shallow aquifers for storage and later release to streams during periods of base flow. The area of the basin with the highest base flows is the Sand Hills region in parts of Moore, Harnett, Hoke, and Cumberland Counties. Streams in the Sand Hills have the highest unit low flows in the study area as well as in much of North Carolina. Well-drained sandy soils in combination with higher topographic relief relative to other areas in the Coastal Plain contribute to the occurrence of high potentials for sustained base flows.\r\n\r\nA number of sites in the upper part of the Cape Fear River Basin underlain by the Carolina Slate Belt and Triassic basin, as well many sites in lower areas of the Coastal Plain (particularly the Northeast Cape Fear River Basin), have zero or minimal (defined as less than 0.05 cubic foot per second) 7Q10 discharges. In this area, the poorly sustained base flows are reflective of either (1) thin soils that have very little storage of water to sustain streams during base-flow periods (Carolina Slate Belt), or (2) soils having very low infiltration rates (Triassic basin). As a result, there is insufficient water stored in the surficial aquifers for release to streams during extended dry periods. Within the part of the study area underlain by the Carolina Slate Belt, streams draining basins 5 square miles or less may have zero or minimal 7Q10 discharges. The part of the study area underlain by the Triassic basin has a higher drainage-area threshold at 35 square miles, below which streams will likely have zero or minimal 7Q10 discharges.\r\n\r\nOccurrences of zero or minimal 7Q10 discharges in the Coastal Plain were noted, though on a more widespread basis. In this area, low flows are more likely affected by the presence of poorly drained soils in combination with very low topographic relief relative to other areas in the Coastal Plain, particularly the Sand Hills. In eastern Harnett County and northeastern Cumberland County, basins with less than 3 square miles may be prone to having zero or minimal 7Q10 discharges. Soils in this area have been described as a mixture of sandy and clay soils. In the Northeast Cape Fear River Basin, particularly on the western side of the river, streams draining less than 8 square miles may have zero or minimal 7Q10 discharges. The poorly drained clay soils along with very little topographic relief results in the low potential for sustained base flows in this part of the study area.\r\n\r\nDrainage area and low-flow discharge profiles are presented for 13 streams in the Cape Fear River Basin; these profiles reflect a wide range in basin size, characteristics, and streamflow conditions.
