Bruce Parks
1983, Water-Resources Investigations Report 83-4173
Water quality and streamflow in the Russian River basin during low-flow seasons (May to October), were studied for water years 1973-78 to document water-quality and streamflow conditions in the basin, and to determine the extent and cause of any water-quality impairment. The most important factors affecting surface-water quality and streamflow...
Effects of the drought of 1980-81 on streamflow and on ground-water levels in Georgia
R.F. Carter
1983, Water-Resources Investigations Report 83-4158
The 1980-81 drought resulted in the lowest rates of streamflow since 1954 in most areas of Georgia, and the lowest since 1925 in some areas. Over most of the State, minimum average streamflows for periods of 1, 7, 30, 60, 90, and 183 consecutive days receded to low levels estimated...

S. N. Hamlin
1983, Water-Resources Investigations Report 82-4121
An injection-extraction well network in the Palo Alto Baylands along the San Francisco Bay, California, was designed to flush the shallow aquifer system of saline water and prevent further inland saline contamination. Clogging processes and solution migration in the vicinity of one injection well were studied. Cyclic evaporative concentration of...
Streamflow losses and changes in ground-water levels along the Salt and Gila Rivers near Phoenix, Arizona — February 1978 to June 1980
L. J. Mann, P. B. Rohne
1983, Water-Resources Investigations Report 83-4043
From March 1978 to June 1980, high runoff from the Salt and Verde drainage basins combined with large carryover storage in a reservoir system led to the release of about 8.26 million acre-feet of water. About 2.89 million acre-feet of the water was diverted above Granite Reef Dam, and about...
Use of flumes in measuring discharge
F. A. Kilpatrick, V.R. Schneider
1983, Techniques of Water-Resources Investigations 03-A14
Flumes for measuring discharge are usually of two general groups-critical-flow flumes and supercritical-flow flumes. In this chapter, the underlying design principles for each group are discussed; the most commonly used flumes are described and their discharge ratings presented. There is also discussion of considerations in choosing and fitting the appropriate...

Subsidence from underground mining; environmental analysis and planning considerations
Fitzhugh T. Lee, John F. Abel
1983, Circular 876
Subsidence, a universal process that occurs in response to the voids created by extracting solids or liquids from beneath the Earth's surface, is controlled by many factors including mining methods, depth of extraction, thickness of deposit, and topography, as well as the in situ properties of the rock mass above...
Computation of inflows and outflows of eight regulated lakes in the Oswego River Basin, New York, 1930-79
Richard Lumia, R. B. Moore
1983, Water-Resources Investigations Report 82-4112
Estimates of daily inflows and outflows of eight regulated lakes in the Oswego River basin and discharges of three rivers draining these lakes were computed and compiled for use in evaluated lake-regulation procedures in the basin 's stream and reservoir system and are stored on computer. This report includes a...
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...
Ground-water hydrology before, during, and after coal strip mining of a small watershed in Coshocton County, Ohio
A. C. Razem
1983, Water-Resources Investigations Report 83-4155
Ground-water conditions before, during, and after surface mining of a small watershed are described as part of a study to determine the effects of mining on hydrologic systems. The watershed was underlain by stratified sedimentary rocks containing three aquifers. The top and middle aquifers were perched above clay beds that...
Estimation of nonpoint source loadings of phosphorus for lakes in the Puget Sound region, Washington
Robert J. Gilliom
1983, Water Supply Paper 2240
Control of eutrophication of lakes in watersheds undergoing development is facilitated by estimates of the amounts of phosphorus (P) that reach the lakes from areas under various types of land use. Using a mass-balance model, the author calculated P loadings from present-day P concentrations measured in lake water and from...
Time-domain electromagnetic tests in the Wadi Bidah District, Kingdom of Saudi Arabia

1983, Open-File Report 83-613
A time-domain electromagnetic (TDEM) method was tested in two areas of mineralization in Precambrian rocks in the Wadi Bidah district, Kingdom of Saudi Arabia. Transient-decay voltages in profile mode were measured across the Sha'ab at Tare and Rabathan prospects by use of three transmitterreceiver loop configurations. At the Sha'ab at...
