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...
Numerical simulation of ground-water flow in lower Satus Creek Basin, Yakima Indian Reservation, Washington
E. A. Prych
1983, Water-Resources Investigations Report 82-4065
A multilayer numerical model of steady-state ground-water flow in lower Satus Creek basin was constructed, calibrated using time-averaged data, and used to estimate the long-term effects of proposed irrigation-water management plans on ground-water levels in the area. Model computations showed that irrigation of new lands in the Satus uplands would...
Sediment transport in the Tanana River near Fairbanks, Alaska, 1980-81
R.L. Burrows, P.E. Harrold
1983, Water-Resources Investigations Report 83-4064
Suspended-sediment- and bedload-transport rates for the Tanana River near Fairbanks, Alaska, can be related to water discharge. Annual sediment loads can be computed using these relations. For a site at Fairbanks, the annual loads in 1980 were 22.0 million metric tons of suspended sediment and 272,000 metric tons of bedload;...
Ground-water quality in the western Snake River basin, Swan Falls to Glenns Ferry, Idaho
D. J. Parliman
1983, Water-Resources Investigations Report 83-4062
Water-quality data were collected from 92 wells in the western Snake River basin, Swan Falls to Glenns Ferry, Idaho. Current data were compiled with pre-1980 data from 116 wells to define water-quality conditions in major aquifers. Factors affecting water quality are composition of aquifer materials, water temperature, and source of...
Appraisal of water-quality conditions, lower Black River, Windsor County, Vermont
K. W. Toppin
1983, Water-Resources Investigations Report 82-4116
Six hydroelectric power dams are planned along a 22-mile reach of the lower Black River in southeastern Windsor County, Vermont. Data were collected at 10 stations, during water years 1977-81, to appraise quality conditions before construction. Average specific conductance of Black River is 101 micromhos indicating low concentrations of dissolved...
Mean annual runoff and peak flow estimates based on channel geometry of streams in northeastern and western Montana
Charles Parrett, R. J. Omang, J. A. Hull
1983, Water-Resources Investigations Report 83-4046
Equations for estimating mean annual runoff and peak discharge from measurements of channel geometry were developed for western and northeastern Montana. The study area was divided into two regions for the mean annual runoff analysis, and separate multiple-regression equations were developed for each region. The active-channel width was determined to...
Flood estimates for ungaged streams in Glacier and Yellowstone National Parks, Montana
R. J. Omang, Charles Parrett, J. A. Hull
1983, Water-Resources Investigations Report 83-4147
Estimates of 100-year discharges were made at 59 sites in Glacier National Park and 21 sites in Yellowstone National Park to assist the National Park Services in quantifying stream inflow and outflow in the Parks. The estimates were made using regression equations previously developed for Montana. The resulting 100-year discharges...
Compilation of revised ages of volcanic units in the San Juan Mountains, Colorado; recalculated K-Ar age determinations using IUGS constants
Ken Hon, Harald H. Mehnert
1983, Open-File Report 83-668
Previously published K-Ar age determinations for the middle to late Tertiary San Juan volcanic field have been recalculated using the 1977 IUGS constants. Revised ages, original analytical data, and brief sample descriptions are presented in table 2 for all available dated volcanic units. A generalized stratigraphic column is also included...
Meteorological, water-temperature, and discharge data for the Mattole River basin, Humboldt County, California
R.D. Noble, Alan P. Jackman
1983, Water-Resources Investigations Report 78-81
To overcome a major difficulty in the testing of the validity of river-temperature models - the lack of adequate precise synoptic data for an entire river basin - synoptic meteorologic, water-temperature, and discharge data were obtained in the Mattole River Basin in northern California during the period June 10 through...
Impact of discharges from point and nonpoint sources on water quality of the upper Reedy River near Greenville, South Carolina
D.I. Cahal, G. K. Speiran
1983, Water-Resources Investigations Report 83-4054
Impacts of discharge from nonpoint sources in the urban area of Greenville, South Carolina and from the point source, the Mauldin Road Wastewater Treatment Plant, on water quality of the Reedy River were studied from October 1979 through September 1980. Streamflow and water-quality data were collected before and during two...
Flood characteristics of urban watersheds in the United States
Vernon B. Sauer, W.O. Thomas Jr., V.A. Stricker, K. V. Wilson
1983, Water Supply Paper 2207
A nationwide study of flood magnitude and frequency in urban areas was made for the purpose of reviewing available literature, compiling an urban flood data base, and developing methods of estimating urban floodflow characteristics in ungaged areas. The literature review contains synopses of 128 recent publications related to urban floodflow....
