Storm-runoff generation in the Permanente Creek drainage basin, west central California - An example of flood-wave effects on runoff composition
K.M. Nolan, B. R. Hill
1990, Journal of Hydrology (113) 343-367
Variations in the isotopic and chemical composition of storm runoff in the 10.6-km2 Permanente Creek basin, Santa Clara County, California, indicate that changes in water composition lag behind changes in streamflow. This lag occurs even though field observations and rainfall-runoff modeling indicate that much of the storm runoff must be...
Effect of faults on fluid flow and chloride contamination in a carbonate aquifer system
M.L. Maslia, D.C. Prowell
1990, Journal of Hydrology (115) 1-49
A unified, multidiscipline hypothesis is proposed to explain the anomalous pattern by which chloride has been found in water of the Upper Floridan aquifer in Brunswick, Glynn County, Georgia. Analyses of geophysical, hydraulic, water chemistry, and aquifer test data using the equivalent porous medium (EPM) approach are used to support...
A method to extract soil water for stable isotope analysis
Kinga M. Revesz, Peter H. Woods
1990, Journal of Hydrology (115) 397-406
A method has been developed to extract soil water for determination of deuterium (D) and 18O content. The principle of this method is based on the observation that water and toluene form an azeotropic mixture at 84.1°C, but are completely immiscible at ambient temperature. In a specially designed distillation apparatus, the...
Topographic effects on flow path and surface water chemistry of the Llyn Brianne catchments in Wales
D.M. Wolock, G.M. Hornberger, T.J. Musgrove
1990, Journal of Hydrology (115) 243-259
Topographic shape is a watershed attribute thought to influence the flow path followed by water as it traverses a catchment. Flow path, in turn, may affect the chemical composition of surface waters. Topography is quantified in the hydrological model TOPMODEL as the relative frequency distribution of the index ln(atanB), where...
Modelling streamwater chemistry as a mixture of soilwater end-members - An application to the Panola Mountain catchment, Georgia, U.S.A.
R. P. Hooper, N. Christophersen, N.E. Peters
1990, Journal of Hydrology (116) 321-343
Streamwater chemistry at Panola Mountain research catchment, Georgia, U.S.A., is explained as a mixture of representative soilwater solutions that are considered to be temporally invariant to a first approximation. The selection of three end-members from all sampled soil waters is evaluated by comparing the observed and predicted streamwater concentration of...
Modelling streamwater chemistry as a mixture of soilwater end-members - A step towards second-generation acidification models
N. Christophersen, C. Neal, R. P. Hooper, R.D. Vogt, S. Andersen
1990, Journal of Hydrology (116) 307-320
In present acidification models, soilwater characteristics, though modelled, are seldom checked against field observations. Given that such data are now collected as part of many catchment studies, a technique is developed whereby stream water can be predicted as a mixture of the observed soilwater classes or end-members. Provided that a...
Volcanic and seismic hazards on the Island of Hawaii
Water Resources Division, U.S. Geological Survey
1990, Report
The eruptions of volcanoes often have direct, dramatic effects on the lives of people and on their property. People who live on or near active volcanoes can benefit greatly from clear, scientific information about the volcanic and seismic hazards of the area. This booklet provides such information for the residents...

National water summary 1987: Hydrologic events and water supply and use
United States Geological Survey
1990, Water Supply Paper 2350
Water use in the United States, as measured by freshwater withdrawals in 1985, averaged 338,000 Mgal/d (million gallons per day), which is enough water to cover the 48 conterminous States to a depth of about 2.4 inches. Only 92,300 Mgal/d, or 27.3 percent of the water withdrawn, was consumptive use...
Simulation of ground-water flow in aquifers in Cretaceous rocks in the central Coastal Plain, North Carolina
J. L. Eimers, W.L. Lyke, A. R. Brockman
1990, Water-Resources Investigations Report 89-4153
The principal sources of water-supply in Cretaceous rocks in the central Coastal Plain of North Carolina are the Peedee, Black Creek, and upper Cape Fear aquifers. Ground-water withdrawals from these aquifers have increased from about 0.25 million gallons per day in 1910 to over 29 million gallons per day in...

1990, Water-Resources Investigations Report 89-4205
Approximately 2,700 miscellaneous discharge measurements for 171 large springs in 28 counties of East Tennessee, predominantly within the Valley and Ridge physiographic province, were analyzed statistically and results tabulated to summarize data useful to the Appalachian Valleys-Piedmont Regional Aquifer System Analysis study. The number of measurements at each spring ranged...

S. J. Field, D.J. Graczyk
1990, Water-Resources Investigations Report 89-4089
An intensive data-collection program for the Black Earth Creek basin in southern Wisconsin was conducted from October 1984 through September 1986 to assess the hydrology, aquatic macrophytes, and water quality in Black Earth Creek by the U.S. Geological Survey, in cooperation with the Wisconsin Department of Natural Resources. Three sites...
Water resources of Codington and Grant counties, South Dakota
D. S. Hansen
1990, Water-Resources Investigations Report 89-4147
The primary sources of surface water in Codington and Grant Counties are Lakes Kampeska and Pelican and numerous potholes in western Codington County. Seasonal variations in streamflow and lake levels are directly related to seasonal variations in precipitation and evapotranspiration. Dissolved-solids concentrations in water from streams and lakes increase as...

Long-term effects of surface coal mining on ground-water levels and quality in two small watersheds in eastern Ohio
W. L. Cunningham, R.L. Jones
1990, Water-Resources Investigations Report 90-4136
Two small watersheds in eastern Ohio that were surface mined for coal and reclaimed were studied during 1986-89. Water-level and water-quality data were compared with similar data collected during previous investigations conducted during 1976-83 to determine long-term effects of surface mining on the hydrologic system. Before mining, the watersheds were...
