Techniques for estimating peak-flow frequency relations for North Dakota streams
Tara Williams-Sether
1992, Water-Resources Investigations Report 92-4020
This report presents techniques for estimating peak-flow frequency relations for North Dakota streams.  In addition, a generalized skew coefficient analysis was completed for North Dakota to test the validity of using the generalized skew coefficient map in Bulletin 17B of the Hydrology Subcommittee of the Interagency Advisory Committee on Water...
Simulation of water-table response to management alternatives, central part of the western San Joaquin Valley, California
K.R. Belitz, S.P. Phillips
1992, Water-Resources Investigations Report 91-4193
The occurrence of selenium in agricultural drainwater in the central pan of the western San Joaquin Valley, California, has focused concern on alternatives other than agricultural drains for managing shallow, poor-quality ground water. A transient, three-dimensional, finite-difference ground-water flow model was developed to assess the response of the water table...
Description and effects of 1988 drought on ground-water levels, streamflow, and reservoir levels in Indiana
K. K. Fowler
1992, Water-Resources Investigations Report 91-4100
Documentation of the 1988 drought in Indiana was undertaken to aid water-management agencies and planners concerned with periods of below-normal precipitation and their effect on commercial, agricultural, and residential water use. Precipitation, temperature, Palmer Drought Severity Indices, and ground- and surface-water levels from water years 1988 and 1989 were compared...
Evaluation of agricultural best-management practices in the Conestoga River headwaters, Pennsylvania; description and water quality of the Little Conestoga Creek headwaters prior to the implementation of nutrient management
D. K. Fishel, M. J. Brown, K. M. Kostelnik, M.A. Howse
1992, Water-Resources Investigations Report 90-4131
The headwaters of the Conestoga River are being studied to determine the effects of agricultural Best-Management Practices on surface-water and ground-water quality. As part of this study, a 5.82-square-mile area of the Little Conestoga Creek headwaters (Small Watershed) was monitored during 1984-86, prior to implementation of Best-Management Practices. This report...
Sediment properties and water movement through shallow unsaturated alluvium at an arid site for disposal of low-level radioactive waste near Beatty, Nye County, Nevada
Jeffrey M. Fischer
1992, Water-Resources Investigations Report 92-4032
A commercial disposal facility for low-level radioactive waste has been in operation near Beatty, Nevada, since 1962. The facility is in the arid Amargosa Desert where wastes are buried in trenches excavated into unsaturated alluvial sediments. Thick unsaturated zones in arid environments offer many potential advantages for disposal of radioactive...
Low-flow characteristics at selected sites on streams in eastern Puerto Rico
Luis Santiago-Rivera
1992, Water-Resources Investigations Report 92-4063
This report presents analyses of low-flow data for 12 continuous-record streamflow gaging stations and 81 partial-record sites in eastern Puerto Rico. Information on low-flow magnitude and frequency is essential in hydrologic studies and for optimum development of surface water resources. The report includes analyses of low-flow data and...
Hydrogeology, water quality, and potential for transport of organochlorine pesticides in ground water at the North Hollywood Dump, Memphis, Tennessee
R. E. Broshears, M. W. Bradley
1992, Water-Resources Investigations Report 91-4022
Geologic, hydrologic, and water-quality data indicate that ground-water contamination is confined to shallow horizons within the unconfined aquifer underlying the North Hollywood Dump in Memphis, Tennessee. The dump is a closed municipal-industrial landfill that has been ranked as Tennessee's potentially most dangerous hazardous-waste site. Toxic constituents of concern at the...
Documentation of a digital spatial data base for hydrologic investigations, Broward County, Florida
R.S. Sonenshein
1992, Water-Resources Investigations Report 92-4061
Geographic information systems have become an important tool in planning for the protection and development of natural resources, including ground water and surface water. A digital spatial data base consisting of 18 data layers that can be accessed by a geographic information system was developed for Broward County, Florida. Five...
Summary of hydrologic data for the San Gabriel River basin and Edwards Aquifer, Georgetown area, Texas, water year 1990
William E. Reeves, Larry F. Land
1992, Open-File Report 92-160
The Edwards aquifer is the principal source of freshwater for municipal, domestic, and industrial users in the Georgetown area.  Other sources of freshwater are Lake Georgetown and the streams draining the San Gabriel River basin.  Lake Georgetown, located on the North Fork San Gabriel River west of Georgetown, is a...
Water resources of Massachusetts
Alison C. Simcox
1992, Water-Resources Investigations Report 90-4144
This report describes the water resources of Massachusetts. It contains sections describing the location, use, quality, and management of water resources in Massachusetts, followed by a summary of the surface water and ground-water resources of all 27 river basins designated by the State for planning purposes. The data for each...
Effects of low-level radioactive-waste disposal on water chemistry in the unsaturated zone at a site near Sheffield, Illinois, 1982-84
C.A. Peters, Robert G. Striegl, P. C. Mills, R. W. Healy
1992, Water Supply Paper 2390
A 1982-84 field study defined the chemistry of water collected from the unsaturated zone at a low-level radioactive-waste disposal site near Sheffield, Bureau County, Ill. Chemical data were evaluated to determine the principal, naturally occurring geochemical reactions in the unsaturated zone and to evaluate waste-induced effects on pore-water chemistry. Samples...
