Geologic mapping of Kentucky: A history and evaluation of the Kentucky Geological Survey--U.S. Geological Survey Mapping Program, 1960-1978
Earle Rupert Cressman, Martin C. Noger
1981, Circular 801
In 1960, the U.S. Geological Survey and the Kentucky Geological Survey began a program to map the State geologically at a scale of 1:24,000 and to publish the maps as 707 U.S. Geological Survey Geologic Quadrangle Maps. Fieldwork was completed by the spring of 1977, and all maps were published...

Ground-water reconnaissance of part of the lower Kenai Peninsula, Alaska
G.L. Nelson, P.R. Johnson
1981, Open-File Report 81-905
Most residential and industrial development of the Lower Kenai Peninsula, Alaska, is along the coast of Cook Inlet. Most of the information about subsurface conditions is obtained from wells along the coast. Ground water is recharged by local precipitation, and slow drainage of ground water to the streams maintains streamflow...

1981, Water-Resources Investigations Report 81-41
A limnological and geochemical survey of Williams Lake, Minnesota, was made in 1979 to provide an initial interpretive description of the lake and the contiguous ground-water system. This survey was made as part of a continuing research program related to the investigation of the interaction of lakes and their contiguous...

Emergency assessment of Mount St. Helens post-eruption flood hazards, Toutle and Cowlitz rivers, Washington
Marshall E. Jennings, V.R. Schneider, P. E. Smith
1981, Circular 850-I
During several periods of volcanic-ash eruption at Mount St. Helens, Wash., (March 30, May 25-26, May 30-June 2, and June 12-13, 1980) strong winds from the north occurred at high altitudes. As a result, the volcanic ash fell some 50 miles to the south in the Bull Run watershed, the...

Stormwater quality processes for three land-use areas in Broward County, Florida
Harold C. Mattraw Jr., Robert A. Miller
1981, Water-Resources Investigations Report 81-23
Systematic collection of rainfall, runoff, and water-quality samples from three small urban areas of Broward County, Florida, were obtained between 1974 and 1977. Stormwater loads for 30 or more storms were computed for the residential, highway, and commercial investigation areas. Stepwise, multiple, linear regression models were constructed for total nitrogen,...
An appraisal of surface-water quality in the Alameda Creek Basin, California, October 1974-June 1979
L.E. Lopp
1981, Water-Resources Investigations Report 81-46
Areal and seasonal variations in the quality of surface water in the Alameda Creek basin, California., from 1974 to 1979 were analyzed to determine the effects of wastewater discharges and imported water releases. Statistically significant differences were found among mean values of constituents in streamflow below the treated wastewater discharge...

Assessment of the Santa Margarita Sandstone as a source of drinking water for the Scotts Valley area, Santa Cruz County, California
K. S. Muir
1981, Water-Resources Investigations Report 81-6
Scotts Valley, Calif., is a rural residential area with a rapidly expanding population. Its mediterranean-type climate yields an average annual rainfall of 40 inches. The Santa Margarita Sandstone is the principal aquifer in the area, supplying about 90 percent of all water for domestic purposes. Sources of recharge for the...

Ground-water resources of the White River basin, Madison County, Indiana
Wayne W. Lapham
1981, Water-Resources Investigations Report 81-35
The ground-water resources of the White River basin in and near Madison County, Indiana, were investigated by mapping the aquifers, estimating their hydraulic properties, determining the distribution of potentiometric head in the aquifers, and estimating some of the components of the ground-water budget from data collected in the field. This...
Kriging analysis of mean annual precipitation, Powder River Basin, Montana and Wyoming
M.R. Karlinger, James A. Skrivan
1981, Water-Resources Investigations Report 80-50
Kriging is a statistical estimation technique for regionalized variables which exhibit an autocorrelation structure. Such structure can be described by a semi-variogram of the observed data. The kriging estimate at any point is a weighted average of the data, where the weights are determined using the semi-variogram and an assumed...

Since April 1970 the U.S. Geological Survey has operated an estuarine water quality monitor in the upper reach of Rhode River, a small embayment on the northwestern shore of Chesapeake Bay. This report analyzes variations in diel oxygen over the period April 1970 through January 1979. The diel oxygen range...
User's guide for a general purpose dam-break flood simulation model (K-634)
Larry F. Land
1981, Water-Resources Investigations Report 80-116
An existing computer program for simulating dam-break floods for forecast purposes has been modified with an emphasis on general purpose applications. The original model was formulated, developed and documented by the National Weather Service. This model is based on the complete flow equations and uses a nonlinear implicit finite-difference numerical...
