Estimation of the recharge area contributing water to a pumped well in a glacial-drift, river-valley aquifer
D. J. Morrissey
1987, Open-File Report 86-543
The highly permeable, unconfined, glacial drift aquifers that occupy most New England river valleys constitute the principal source of drinking water for many communities that obtain part or all of their public water supply from groundwater. Analytical , two-dimensional numerical and three-dimensional numerical models were used to delineate contributing areas...

The U.S. Geological Survey, in cooperation with the city of Houston, began...
Average Annual Runoff in the United States, 1951-80
W.A. Gebert, David J. Graczyk, William R. Krug
1987, Hydrologic Atlas 710
Runoff is the water in a river or stream that results from precipitation falling on the drainage basin. It is the net discharge into the stream from surface-water and ground-water sources with losses occurring from evapotranspiration and other consumptive uses. Runoff can be expressed by a variety of numerical values,...

John E. Moore, C. William Cardin, editor(s)
1987, Open-File Report 87-111
Effective management of water resources requires an understanding of hydrologic systems and the factors that determine the distribution, availability, and quality of water. Within the Federal Government, the U.S. Geological Survey has the principal responsibility for providing hydrologic information and for appraising the Nation's water resources. The water resources activities...
Climatic data for the Cottonwood Lake area, Stutsman County, North Dakota, 1983
A.M. Sturrock, B.A. Hanson, J.L. Scarborough, T. C. Winter
1987, Open-File Report 87-216
Research on the hydrology of the Cottonwood Lake area, Stutsman County, North Dakota, includes study of evaporation. Climatic data needed for energy-budget and mass-transfer evaporation studies that were collected during 1983 include water-surface temperature, sediment temperature, dry-bulb and wet-bulb air temperature, vapor pressure at and above the water surface, wind...
Reflections on writing hydrologic reports
Perry G. Olcott
1987, Open-File Report 87-398
Reporting of scientific work should be characterized by a logical argument that is developed through presentation of the problem, tabulation and display of data pertinent to the problem , and testing and interpretation of the data to prove hypotheses that address the problem. Organization of the report is vital to...
Hydrogeologic characteristics of the Lee Acres Landfill Area, San Juan County, New Mexico
K. D. Peter, R. A. Williams, K. W. King
1987, Water-Resources Investigations Report 87-4246
Identification of the presence of volatile organic compounds in liquid-waste lagoons in New Mexico at the Lee Acres landfill, beneath a refinery south of the landfill, and in nearby residential wells has led to an hydrologic investigation of the area. The alluvium underlying an arroyo adjacent to the landfill mostly...
Hydrologic effects of artificial-recharge experiments with reclaimed water at East Meadow, Long Island, New York
B.J. Schneider, H. F. Ku, E. T. Oaksford
1987, Water-Resources Investigations Report 85-4323
Artificial recharge experiments were conducted at East Meadow, Long Island, New York, from October 1982 through January 1984 to evaluate the degree of groundwater mounding and the chemical effects of artificially replenishing the groundwater system with tertiary-treated wastewater. More than 800 million gallons of treated effluent was returned to the...
Hydrologic data from the integrated lake-watershed acidification study in the west-central Adirondack Mountains, New York : October 1977 through January 1982
N.E. Peters, Peter S. Murdoch, F.N. Dalton
1987, Open-File Report 85-80
Hydrologic data were collected from three forested headwater lake watersheds in Herkimer and Hamilton Counties from October 1977 through early January 1982 as part of the Integrated Lake-Watersheds Acidification Study (ILWAS). ILWAS was established in 1977 to determine why these lakes differ in pH when all receive equal amounts of...
