Computed and estimated pollutant loads, West Fork Trinity River, Fort Worth, Texas, 1997
Paul W. McKee, Harry C. McWreath
2001, Water-Resources Investigations Report 2001-4253
In 1998 the U.S. Geological Survey, in cooperation with the Trinity River Authority, did a study to estimate storm-runoff pollutant loads using two models—a deterministic model and a statistical model; the estimated loads were compared to loads computed from measured data for a large (118,000 acres) basin in the Dallas-Fort...
Physical, Chemical, and Biological Methods and Data from the Urban Land-Use-Gradient Study, Des Plaines and Fox River Basins, Illinois, 1999-2001
Debbie L. Adolphson, Terri Arnold, Faith A. Fitzpatrick, Mitchell A. Harris, Kevin D. Richards, Barbara C. Scudder, Jana S. Stewart
2001, Open-File Report 2001-459
Physical, chemical, and biological data were collected at 46 sites in the Fox and Des Plaines River Basins as part of the upper Illinois River Basin study of the U.S. Geological Survey?s National Water-Quality Assessment Program. The data, collected from 1999 to 2001, will be used to determine the effects...
Raster images of geologic maps of Middle Proterozoic Belt strata in parts of Benewah, Bonner, Kootenai and Shoshone Counties, Idaho and Lincoln, Mineral and Sanders Counties, Montana
David E. Boleneus, Larry M. Appelgate, Nancy L. Joseph, Theodore R. Brandt
2001, Open-File Report 2001-438
Geologic maps of the western part of the Belt Basin of western Montana and northern Idaho were converted into digital raster (TIFF image) format to facilitate their manipulation in geographic information systems. The 85-mile x 100-mile map area mostly contains rocks belonging to the lower and middle Belt Supergroup. The...
Numerical simulation of streamflow distribution, sediment transport, and sediment deposition along Long Beach Creek in Northeast Missouri
David C. Heimann
2001, Water-Resources Investigations Report 2001-4269
This report presents the results of a study conducted by the U.S. Geological Survey in cooperation with the Missouri Department of Conservation to describe the hydrology, sediment transport, and sediment deposition along a selected reach of Long Branch Creek in Macon County, Missouri. The study was designed to investigate spatial...
Calculating depths to shallow magnetic sources using aeromagnetic data from the Tucson Basin
Daniel W. Casto
2001, Open-File Report 2001-505
Using gridded high-resolution aeromagnetic data, the performance of several automated 3-D depth-to-source methods was evaluated over shallow control sources based on how close their depth estimates came to the actual depths to the tops of the sources. For all three control sources, only the simple analytic signal method, the local...
Geology, hydrology, and water quality in the vicinity of a brownfield redevelopment site in Canton, Illinois
Robert T. Kay, David B. Cornue, James R. Ursic
2001, Open-File Report 2001-307
The U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency and Environmental Operations, Inc., assisted in the characterization of the geology, hydrology, and water quality at a Brownfield redevelopment site in Canton, Illinois. The investigation was designed to determine if metals and organic compounds historically used in industrial...
Tampa Bay Integrated Science Pilot Study: Baseline mapping, land surface dynamics and predictive modeling, and hazards vulnerability studies
Michael Crane, Kimberly Yates, Robert Clark, Dean Gesch, Kurt Hess, John Koehmstedt, Dennis Milbert, Bruce Parker, Dan Sechrist, Janet Tilley, Robert Wilson
2001, Open-File Report 2001-398
Tampa Bay and its environs have experienced phenomenal urban growth and significant changes in land cover and land-use practices over the past 50 years. This trend is expected to continue, with the impact of human activity broadening geographically and intensifying throughout the region.One of the immediate impacts of urban growth...
Tampa Bay Integrated Science Pilot Study: wetland characterization
Carole C. McIvor, Ellen Raabe, Kimberly Yates, Bill Carter, Mike Crane, Mario Fernandez, Brandt Henningsen, Sara Kruse, Rich Oches, Ed Proffitt, Randy Runnels, Ramesh Shrestha, Tom Smith, Steve Travis
2001, Open-File Report 2001-390
Coastal wetlands in Tampa Bay consist of mangrove forest and tidal salt marsh. Wetlands buffer storm surges, provide fish and wildlife habitat, and enhance water quality through the removal of water-borne nutrients and contaminants. Substantial areas of both mangrove and salt marsh have been lost to agricultural, residential and industrial...
Effects of land use and travel time on the distribution of nitrate in the Kirkwood-Cohansey aquifer system in southern New Jersey
Leon J. Kauffman, Arthur L. Baehr, Mark A. Ayers, Paul E. Stackelberg
2001, Water-Resources Investigations Report 2001-4117
Residents of the southern New Jersey Coastal Plain are increasingly reliant on the unconfined Kirkwood-Cohansey aquifer system for public water supply as a result of increasing population and restrictions on withdrawals from the deeper, confined aquifers. Elevated nitrate concentrations above background levels have been found in wells in the surficial...
User's guide to SSARRMENU
M. C. Mastin, Thanh Le
2001, Open-File Report 2001-439
The U.S. Geological Survey, in cooperation with Pierce County Department of Public Works, Washington, has developed an operational tool called the Puyallup Flood-Alert System to alert users of impending floods in the Puyallup River Basin. The system acquires and incorporates meteorological and hydrological data into the Streamflow Synthesis and Reservoir...
