Results of a test well in the Nanafalia Formation near Melvin, Choctaw County, Alabama
M. E. Davis, A.K. Sparkes, B.S. Peacock
1983, Water-Resources Investigations Report 82-4108
Test drilling at Melvin, Choctaw County, Alabama, discloses that the Nanafalia Formation (Paleocene) contains freshwater in sand at a distance of 25 miles downdip from the outcrop area. A nearby fault on the north side of Gilberttown-Pickens fault zone does not appear to affect either the head or the water...
Storm runoff as related to urbanization based on data collected in Salem and Portland, and generalized for the Willamette Valley, Oregon
Antonius Laenen
1983, Water-Resources Investigations Report 83-4143
Storm runoff as related to urbanization is defined by a series of regression equations for Salem and for the Willamette Valley, Oregon. In addition to data from 17 basins monitored in the Salem area, data from 24 basins gaged in a previous study in Portland, Oregon - Vancouver, Washington were...
Water-level changes in the high plains regional aquifer, northwestern Oklahoma, predevelopment to 1980
J.S. Havens
1983, Water-Resources Investigations Report 83-4073
During 1978, the U.S. Geological Survey began a 5-year study of the High Plains regional aquifer system to provide hydrologic information for evaluation of the effects of long-term development of the aquifer and to develop computer models for prediction of aquifer response to alternative changes in ground-water management (Weeks, 1978)....
Effects of specific land uses on nonpoint sources of suspended sediment, nutrients, and herbicides, Pequea Creek basin, Pennsylvania, 1979-80
P. L. Lietman, J. R. Ward, T.E. Behrendt
1983, Water-Resources Investigations Report 83-4113
The Susquehanna River Basin Commission and the U.S. Environmental Protection Agency cooperated with the U.S. Geological Survey in a study to quantify nonpoint-source loadings from an agricultural area in Pennsylvania. Pequea Creek, a tributary to the Susquehanna River, drains a 154-square mile agricultural area in Lancaster County, Pennsylvania. Previous studies...
Use of rainfall-simulator data in precipitation-runoff modeling studies
G.C. Lusby, R.W. Lichty
1983, Water-Resources Investigations Report 83-4159
Results of a study using a rainfall simulator to define infiltration parameters for use in watershed modeling are presented. A total of 23 rainfall-simulation runs were made on five small plots representing four representative soil-vegetation types of the study watershed in eastern Colorado. Data for three observed rainfall-runoff events were...
Ground water in north Monterey County, California, 1980
M. J. Johnson
1983, Water-Resources Investigations Report 83-4023
Present ground-water demands exceed long-term recharge throughout much of North Monterey County in the shallow Quaternary deposits--principally the upper part of the Aromas Sand--and the overlying alluvium. Recharge occurs largely from local precipitation, although small quantities of potable ground water from outside areas also recharge these aquifers. Water levels in...
The effects of pumpage, irrigation return, and regional ground-water flow on the water quality at Waiawa water tunnel, Oahu, Hawaii
P. R. Eyre
1983, Water-Resources Investigations Report 83-4097
Waiawa shaft is a 1,700-foot long water tunnel which draws water from the top of the Pearl Harbor Ghyben-Herzberg ground-water lens, Oahu, Hawaii. The application of brackish irrigation water to sugarcane fields overlying Waiawa shaft, combined with relatively low pumping rates at the shaft from 1978 to 1980, caused the...
Evaluation of the San Dieguito, San Elijo, and San Pasqual hydrologic subareas for reclaimed water use, San Diego County, California
J. A. Izbicki
1983, Water-Resources Investigations Report 83-4044
A study was made to determine the suitability of three small hydrologic subareas in San Diego County, California, for reuse of municipal wastewater. Ground-water quality has been impacted by agricultural water use, imported water use, changes in natural recharge patterns, seawater intrusion, and intrusion of ground water from surrounding marine...
A summary of ground-water pumpage in the Central Valley, California, 1961-77
Jonathan Diamond, A. K. Williamson
1983, Water-Resources Investigations Report 83-4037
In the Central Valley of California, a great agricultural economy has been developed in a semiarid environment. This economy is supported by imported surface water and 9 to 15 million acre-feet per year of ground water. Estimates of ground-water pumpage computed from power consumption have been compiled and summarized. Under...
Sediment transport in the Tanana River near Fairbanks, Alaska, 1982
P.E. Harrold, R.L. Burrows
1983, Water-Resources Investigations Report 83-4213
Suspended-sediment and bedload-transport rates for the Tanana River near Fairbanks can be related to water discharge, and annual sediment loads can be computed using these relations. For a site at Fairbanks the annual loads in 1982 were 26.1 million metric tons of suspended sediment and 227,000 metric tons of bedload....
Base flow and ground water in upper Sweetwater Valley, Tennessee
R. D. Evaldi, J.G. Lewis
1983, Water-Resources Investigations Report 83-4068
Base flow measurements showed interbasin transfer of water among sub-basins of upper Sweetwater Valley. In general, topographically higher sub-basins have deficient surface outflow unless significant spring flow occurs in the basin. Topographically lower areas adjacent to the main channel of Sweetwater Creek generally have surplus flow. Major flow surpluses were...
Estimating highest ground-water levels for construction and land use planning — A Cape Cod, Massachusetts, example
Michael H. Frimpter, Martha N. Fisher
1983, Water-Resources Investigations Report 83-4112
High ground water is a major cause of septic-system failures, wet basements, and other problems for suburban and rural residents. A technique for estimating the level to which groundwater can rise as a consequence of weather and seasonal factors has been developed. Water-level records from about 160 sites were used...
Uncertainties in records of annual mean discharge in Maine
R. A. Fontaine
1983, Water-Resources Investigations Report 83-4025
This report documents the results of rating analyses of flow during periods of ice-cover at 33 stations on selected rivers in Maine. Results were obtained through linear multiple regression. It also presents functions relating uncertainties in records to the number of discharge measurements made at these and 21 other stations....
