Digital-simulation and projection of head changes in the Potomac-Raritan-Magothy aquifer system, coastal plain, New Jersey
James E. Luzier
1980, Water-Resources Investigations Report 80-11
The Potomac-Raritan-Magothy aquifer system of Cretaceous age, which is the principal source of water to the major population and industrial centers in the Coastal Plain of New Jersey, has undergone continuous and widespread reduction in head. The reduced head, already below sea level throughout most of the aquifer system, in...
Estimation of background loadings and concentrations of phosphorus for lakes in the Puget Sound region, Washington
Robert J. Gilliom
1980, Open-File Report 80-328
For lakes in watersheds that include developed land, evaluation of eutrophication is facilitated by knowledge of changes in the lakes ' phosphorus concentration since development. A method is described for estimating background phosphorus concentration in lakes of the Puget Sound lowland, Washington. Using a mass-balance ' Vollenweider-type ' model, phosphorus...
Ground-water resources investigation in the Amran Valley, Yeman Arab Republic
G. Chase Tibbitts, James Aubel
1980, Open-File Report 80-774
A program of hydrologic studies and exploratory drilling was conducted intermittently between 1974 and 1978 to evaluate the water-bearing properties of the unconsolidated alluvial sediments and associated rocks in the semi-arid Amran Valley basin, an 800-square-kilometer area in north-central Yemen Arab Republic. Inventory data from 395 wells were compiled, observation...
Maps showing ground-water conditions in the Douglas Basin area, Cochise County, Arizona: 1978
Larry J. Mann, C. S. English
1980, Open-File Report 80-700
The Douglas basin area includes about 1,200 square miles in southeastern Arizona. The main use of ground water is for irrigation. For 1955-77, the estimated ground-water pumpage equaled or exceeded 50,000 acre-feet per year, and for 1966-77, the ground-water pumpage averaged about 109,000 acre-feet per year. Ground-water withdrawals have resulted...
Selected hydrologic data, Arkansas River basin, Pueblo and southeastern Fremont Counties, Colorado, 1975-80
Doug Cain, Patrick Edelmann
1980, Open-File Report 80-1185
Selected hydrologic data collected in 1975-80 as part of water-quality investigations by the U.S. Geological Survey in Pueblo and southeastern Fremont Counties, Colo., are presented in this report. The data, in tabular form, consist of streamflow-discharge measurements for 33 sites, channel-geometry measurements for 97 sites, traveltime data for 12 sites,...
An annotated bibliography of devices developed for direct measurement of seepage
Mark R. Carr, Thomas C. Winter
1980, Open-File Report 80-344
The need for information on the interrelationship of groundwater and surface water is causing a growing interest in methods used for direct measurement of seepage to and from surface-water bodies. Instruments developed for measurement of seepage date from about the mid 1940 's largely in response to the need for...
Hydrologic data from upper Grange Hall Creek basin, Northglenn, Adams County, Colorado
Dennis C. Hall, A.C. Duncan
1980, Open-File Report 80-578
Hydrologic data collected during 1977-79 as part of a water-resources investigation of storm runoff in Upper Grange Hall Creek basin, Adams County, Colo., are presented in this report. Data presented in tabular form consist of: (1) Estimated daily precipitation at one site (April through October, 1978 and 1979); (2) mean...
