Sediment loads, discharges, and yields in the East Branch Mahoning Creek basin, Clearfield and Jefferson Counties, Pennsylvania, June 1979 through September 1981
C. A. Loper, K. L. Wetzel
1988, Water-Resources Investigations Report 85-4213
Rainfall, streamflow, and sediment discharge data were collected from the East Branch Mahoning Creek basin from June 1979 through September 1981 to evaluate sediment discharges from an area in which erosion and sediment controls were being used on surface mined areas. Sediment yields from the basin averaged 144 tons/sq mi/year....
A modification of the U.S. Geological Survey one-sixth order semiquantitative spectrographic method for the analysis of geologic materials that improves limits of determination of some volatile to moderately volatile elements
D.E. Detra, Elmo F. Cooley
1988, Circular 996
A modification of the one-sixth order semi-quantitative emission spectrographic method for the analysis of 30 elements in geologic materials (Grimes and Marranzino 1968) improves the limits of determination of some volatile to moderately volatile elements. The modification uses a compound-pendulum-mounted filter to regulate the amount of emitted light passing into...
Evaluation of the flood hydrology in the Colorado Front Range using precipitation, streamflow, and paleoflood data for the Big Thompson River basin
R.D. Jarrett, J. E. Costa
1988, Water-Resources Investigations Report 87-4117
A multidisciplinary study of precipitation and streamflow data and paleohydrologic studies of channel features was made to analyze the flood hydrology of foothill and mountain streams in the Front Range of Colorado, with emphasis on the Big Thompson River basin, because conventional hydrologic analyses do not adequately characterize the flood...
Geohydrology of the Flathead Indian Reservation, northwestern Montana
S.E. Slagle
1988, Water-Resources Investigations Report 88-4142
The geohydrology of the Flathead Indian Reservation was studied to provide information needed to formulate groundwater development plans. Bedrock in the area consists predominantly of slightly metamorphosed carbonate and fine-grained clasitc rocks of the Precambrian Belt Supergroup. Valley-fill deposits consist of alluvium of Holocene age; glacial and glaciolacustrine boulders, cobbles,...
Effects of urbanization on storm-runoff volume and peak discharge of Valley Creek, eastern Chester County, Pennsylvania
R. A. Sloto
1988, Water-Resources Investigations Report 87-4196
Peak discharge and runoff volume were simulated for 21 storms in the Valley Creek basin using the U.S. Geological Survey Distributed Routing Rainfall-Runoff Model (DR3M). Storm peak discharges ranged from 301 to 900 cubic feet per second. Rainfall was measured at three recording rain gages in the basin. Observed and...
Ground-water flow and solute transport at a municipal landfill site on Long Island, New York – Part 1: Hydrogeology and water quality
E. J. Wexler
1988, Water-Resources Investigations Report 86-4070
Hydrogeology and water quality in a 4 sq mi area surrounding the Brookhaven landfill site in the Town of Brookhaven, New York, were studied in 1981-83. The 60-acre sanitary landfill at the site was excavated in highly permeable glacial outwash that forms the upper glacial aquifer and is lined with...
Simulation of ground-water flow in aquifers along the Susquehanna River in Columbia County, Pennsylvania
J.H. Williams, G.E. Senko
1988, Water-Resources Investigations Report 85-4185
A numerical model of groundwater flow was developed for a 10.3 sq mi area along the Susquehanna River in Columbia County, east central Pennsylvania. Groundwater in the model area primarily is in secondary openings in the carbonate--and clastic-rock aquifers and primary openings in the glacial-outwash aquifer that discontinuously overlies bedrock....
Geologic and geohydrologic reconnaissance of Staten Island, New York
Julian Soren
1988, Water-Resources Investigations Report 87-4048
The public water supply for about 350,000 people on Staten Island (Richmond County)--a mainly suburban 60-sq mi borough of the City of New York is provided by the City from reservoirs in upstate New York. Since 1962, many individuals and businesses have used groundwater for supplemental supply as a result...
Effects of flood controls proposed for West Branch Brandywine Creek, Chester County, Pennsylvania
R. A. Sloto
1988, Water-Resources Investigations Report 86-4054
Twenty-four-hour rainfall, distributed over time according to the U.S. Soil Conservation Service type II rainfall distribution, was used as input to calibrated rainfall-runoff models of three subbasins in the West Branch Brandywine Creek watershed. The effects of four proposed flood controls were evaluated by using these rainfalls to simulate discharge...
Geohydrology and susceptibility of major aquifers to surface contamination in Alabama; area 12
J. C. Scott, R.H. Cobb
1988, Water-Resources Investigations Report 88-4078
This report delineates and describes the geohydrology and susceptibility of major aquifers to contamination in Coffee, Dale, Henry, Houston, and Geneva Counties, Alabama. The major aquifers are the Upper Floridan, Lisbon, Nanafalia-Clayton, and Providence-Ripley aquifers. Estimated groundwater withdrawals for public water supplies are about 42 million gal/day. Maximum withdrawals for...
Distribution of gases in the unsaturated zone at a low-level radioactive-waste disposal site near Sheffield, Illinois
Robert G. Striegl
1988, Water-Resources Investigations Report 88-4025
The unsaturated zone is a medium that provides pneumatic communication for the movement of gases from wastes buried in landfills to the atmosphere, biota, and groundwater. Gases in unsaturated glacial and eolian deposits near a waste-disposal trench at the low-level radioactive-waste disposal site near Sheffield, Bureau County, Illinois, were identified,...
