Stratigraphic and hydrogeologic framework of the Alabama Coastal Plain
M. E. Davis
1988, Water-Resources Investigations Report 87-4112
Tertiary and Cretaceous sand aquifers of the Southeastern United States Coastal Plain comprise a major multlstate aquifer system informally defined as the Southeastern Coastal Plain aquifer system, which is being studied as part of the U.S. Geological Survey's Regional Aquifer System Analysis (RASA) program. The major objectives of each RASA...
Techniques for estimating the magnitude and frequency of floods in Minnesota
J.E. Jacques, D. L. Lorenz
1988, Water-Resources Investigations Report 87-4170
Log-Pearson type III flood-frequency analyses were made of annual series peak-flow records from 246 gaging stations on unregulated streams in Minnesota having watersheds ranging in area from 0.08 to 2,520 square miles. These flood discharges were related to watershed and climatic characteristics by using multiple-regression techniques. On the basis of...
Hydrogeology and simulated effects of ground-water development on an unconfined aquifer in the Closed Basin Division, San Luis Valley, Colorado
G.J. Leonard, Kenneth R. Watts
1988, Water-Resources Investigations Report 87-4284
Wells completed in an unconfined aquifer in the Closed Basin Division of the San Luis Valley Project, Colorado, are expected to provide about 101,800 acre-ft of groundwater/year to the Rio Grande when this project is completed. Lowering of groundwater levels in the unconfined aquifer is expected to decrease the quantity...
Water quality of the Lexington Reservoir, Santa Clara County, California, 1978-80
R.T. Iwatsubo, M. A. Sylvester, I.S. Gloege
1988, Water-Resources Investigations Report 87-4253
Analysis of water samples from Lexington Reservoir and Los Gatos Creek upstream from the reservoir from June 1978 through September 1980 showed that water generally met water-quality objectives identified by California Regional Water Quality Control Board, San Francisco Bay Region. Water-temperature profiles show that Lexington Reservoir is a warm monomictic...
Channel infiltration from floodflows along the Pawnee River and its tributaries, west-central Kansas
James B. Gillespie, C. A. Perry
1988, Water-Resources Investigations Report 88-4055
Most of the streams is west-central Kansas are ephemeral. Natural recharge to the alluvial aquifers underlying these streams occurs during periods of storm runoff in the ephemeral channels. Proposed flood-retarding structures within the basin will alter the downstream runoff characteristics in these channels by reducing the peak flow and increasing...
Reassessment of the Georgetown limestone as a hydrogeologic unit of the Edwards Aquifer, Georgetown area, Texas
L. F. Land, M.E. Dorsey
1988, Water-Resources Investigations Report 88-4190
The Edwards aquifer consists of geologic units known as the Comanche Peak (oldest) and Edwards Limestones, Kiamichi Formation, and Georgetown Limestone. The Edwards Limestone is the main water-bearing zone. The shallow geologic units dip to the east-southeast at a slope of 50 to 100 feet per mile in the Georgetown...
Effects of fluctuating river-pool stages on ground-water levels in the adjacent alluvial aquifer in the lower Arkansas River, Arkansas
D.A. Freiwald, G.D. Grosz
1988, Water-Resources Investigations Report 87-4279
The U.S. Geological Survey conducted a study in cooperation with the U.S. Army Corps of Engineers to determine the effect of fluctuating the lower Arkansas River. A network of 41 wells was used to delineate 4 cross sections adjacent to river pools 2 and 5 of the McClellan-Kerr Arkansas River...
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...
Hydrogeology, aquifer characteristics, and ground-water flow of the surficial aquifer system, Broward County, Florida
J.E. Fish
1988, Water-Resources Investigations Report 87-4034
The surficial aquifer system, in which an unconfined groundwater flow system exists, comprises the sediments from land surface to the intermediate confining unit (formerly called the Floridan aquiclude) in Broward County, Florida. These sediments have hydraulic conductivities that range more than seven orders of magnitude from about 0.001 ft/d to...
Hydrology of the lower Little Red River, Arkansas, and a procedure for estimating available streamflow
G.D. Grosz, J. E. Terry, A.P. Hall
1988, Water-Resources Investigations Report 88-4008
The U.S. Geological Survey, in cooperation with the Arkansas Soil and Water Conservation Commission, conducted a hydrologic investigation of the lower Little Red River from near Searcy, Arkansas (mi 31.7), to the river 's mouth at its confluence with the White River. During 1983 and 1984, data were collected on...
Regionalization of peak discharges for streams in Kentucky
Anne F. Choquette
1988, Water-Resources Investigations Report 87-4209
Multiple regression analysis was used to delineate hydrologically distinct regions in Kentucky, and to develop regression models for estimating peak discharge for unregulated streams in these regions. The regression models provide estimates of flood quantiles with associated average recurrence intervals of 2, 5, 10, 25, 50, and 100 years. The...
Discharge ratings for control structures at McHenry Dam on the Fox River, Illinois
G. G. Fisk
1988, Water-Resources Investigations Report 87-4226
Twenty-three measurement of discharge were used to determine discharge ratings for the five adjustable sluice gates, spillway and fish ladder at McHenry Dam on the Fox River in Illinois. Discharge ratings were determined for free weir, free orifice, and submerged orifice flow regimes. Hydraulic conditions that identify flow regimes at...
Estimating average dissolved-solids yield from basins drained by ephemeral and intermittent streams — Green River basin, Wyoming
L. L. DeLong, D. K. Wells
1988, Water-Resources Investigations Report 87-4222
A method was developed to determine the average dissolved-solids yield contributed by small basins characterized by ephemeral and intermittent streams in the Green River basin in Wyoming. The method is different from that commonly used for perennial streams. Estimates of dissolved-solids discharge at eight water quality sampling stations operated by...
Water resources of Miner County, South Dakota
N.C. Koch, S.D. McGarvie
1988, Water-Resources Investigations Report 86-4035
Miner County is a rural agricultural area of 572 sq mi in east-central South Dakota. All streams in the county are intermittent and usually are recharged only from spring snowmelt and precipitation. Most ponds and sloughs may go dry in summer and during drought conditions, while larger lakes and ponds...
Simulation of quantity and quality of storm runoff for urban catchments in Fresno, California
J. R. Guay, P. E. Smith
1988, Water-Resources Investigations Report 88-4125
Rainfall-runoff models were developed for a multiple-dwelling residential catchment (2 applications), a single-dwelling residential catchment, and a commercial catchment in Fresno, California, using the U.S. Geological Survey Distributed Routing Rainfall-Runoff Model (DR3M-II). A runoff-quality model also was developed at the commercial catchment using the Survey 's Multiple-Event Urban Runoff Quality...

T. M. Crouch, G. E. Welder
1988, Water-Resources Investigations Report 88-4054
Construction of a proposed drainage system could result in a moderate flow increase in the Pecos River downstream from the McMillan delta. The potential effect of a new line channel of the Pecos River in McMillan delta in southeastern New Mexico would be an increase of less than 11,000 acre-ft/year....

J. R. Knapton, W. E. Jones, J. W. Sutphin
1988, Water-Resources Investigations Report 87-4244
The Sun River area was selected for a reconnaissance investigation of irrigation drainage because sufficient information existed to indicate that potential problems of a toxic nature might exist. The area of study included the Sun River Irrigation Project, Freeze-out Lake Game Management Area, and Benton Lake National Wildlife Refuge. Water,...
