Water-quality assessment of the Cypress Creek watershed, Warrick County, Indiana
Linda L. Bobo, Charles A. Peters
1980, Water-Resources Investigations Report 80-35
The U.S. Soil Conservation Service needs chemical, biological, microbiological, and hydrological data to prepare an environmental evaluation of the water quality in the Cypress Creek watershed, Warrick County, Ind., before plans can be devised to (1) improve water quality, (2) minimize flooding, (3) reduce sedimentation, and (4) provide adequate outlets...
A technique for estimating flood heights on small streams in the city of Charlotte and Mecklenburg County, North Carolina
William H. Eddins, N.M. Jackson Jr.
1980, Water-Resources Investigations Report 80-106
A method for estimating the height reached by floods having recurrence intervals of 10, 20, and 100 years is defined for unregulated streams in Charlotte and Mecklenburg County draining areas of less than 1.0 square mile. Flood heights, defined as the vertical distance between the streambed at riffles and the...
Nitrogen in ground water and surface water from sewered and unsewered areas, Nassau County, Long Island, New York
Stephen E. Ragone, B. G. Katz, G.E. Kimmel, J.B. Lindner
1980, Water-Resources Investigations Report 80-21
Data on nitrogen in groundwater and surface waters in the sewered and unsewered parts of Nassau County were analyzed to evaluate the principal sources of nitrogen and to determine what factors significantly affect its concentration in the upper glacial aquifer and the underlying Magothy aquifer. Nitrate data for water samples...
Weather forecast needs from the viewpoint of hydrology
Donald M. Thomas, Thomas J. Buchanan
1980, Open-File Report 80-754
Hydrologists now depend on directly observed data in their forecasting and only infrequently use meteorological forecasts. Case studies show how reliable meteorological forecasts could be beneficial in flood and drought situations. Hydrologists need meteorological forecasts that recognize spatial variability, that are unbiased, and that have a specified degree of uncertainty....
Potentiometric map of the Meridian-Upper Wilcox Aquifer in Mississippi, fall 1979
B. E. Wasson
1980, Open-File Report 80-590
The potentiometric map of the Meridian-upper Wilcox aquifer is one of a series of maps, prepared by the U.S. Geological Survey in cooperation with the Mississippi Department of Natural Resources, Bureau of Land and Water Resources, delineating the potentiometric surfaces of the major aquifers in Mississippi. In the outcrop area...
Water quality of the Neuse River, North Carolina: Variability, pollution loads, and long-term trends
Douglas A. Harned
1980, Water-Resources Investigations Report 80-36
A water-quality study of the Neuse River, N.C., based on data collected during 1956-77 at the U.S. Geological Survey stations at Clayton and Kinston, employs statistical trend analysis techniques that provide a framework for river quality assessment. Overall, water-quality of the Neuse River is satisfactory for most uses. At Clayton,...
Water resources and geology of the Los Coyotes Indian Reservation and vicinity, San Diego County, California
A.P. Ballog Jr., W. R. Moyle Jr.
1980, Open-File Report 80-960
The water resources of the Los Coyotes Indian Reservation, San Diego County, Calif., are sufficient to supply the limited domestic and stock-water needs of the present residents of the reservation. Surface-water runoff is derived from direct precipitation on the area and from intermittent spring flow. Groundwater occurs in the alluvial...
Exploratory trench across the Pleasant Valley Fault, Nevada
Manuel G. Bonilla, H. A. Villalobos, R. E. Wallace
1980, Open-File Report 80-1245
An exploratory trench was excavated across the 1915 trace of the Pleasant Valley fault 60 km south of Winnemucca, Nevada, to get information on the history of recent displacements on a fault that had produced a major earthquake in historic time, and on the appearance of such a fault in...
Evaluation of water resources in the Reedsport area, Oregon
Joseph F. Rinella, F. J. Frank, A.R. Leonard
1980, Open-File Report 80-444
The water supply for the Reedsport area is obtained from Clear Lake, a 310-acre coastal lake that contains 16, 600 acre-feet of water at full-pool. The lake receives about 6,000 acre-feet of water annually from runoff and direct precipitation, and it loses about 600 acre-feet by evaporation. The 2,100 acre-feet...
Proceedings of Conference XII; Earthquake prediction information
1980, Open-File Report 80-843
The U.S. Geological Survey in cooperation with five cosponsors: California Division of Mines and Geology, California Emergency Services, California Seismic Safety Commission, City of Los Angeles, and Federal Emergency Management Agency, convened a conference on Earthquake Prediction Information in Los Angeles during the period January 28-30, 1980. More than 100...
