Two-dimensional ground-water flow model of the Cretaceous aquifer system of Lee County and vicinity, Mississippi
John Michael Kernodle
1981, Water-Resources Investigations Report 81-70
A two-dimensional ground-water flow model of the Eutaw-McShan and Gordo aquifers in the area of Lee County, Miss., was successfully calibrated and verified using data from six long-term observation wells and two intensive studies of areal water levels. The water levels computed by the model were found to be most...

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...
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...

Limnological and geochemical survey of Williams Lake, Hubbard County, Minnesota
J. W. LaBaugh, G.E. Groschen, Thomas C. Winter
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...

Digital models of ground-water flow in the Cape Cod aquifer system, Massachusetts
John H. Guswa, Denis R. LeBlanc
1981, Open-File Report 80-67
The Cape Cod aquifer system was simulated with three-dimensional finite-difference ground-water-flow models. Five areas were modeled to provide tools that can be used to evaluate the hydrologic impacts of regional water development and waste disposal.The model boundaries were selected to represent the natural hydrologic boundaries of the aquifer. The boundary...

Hydrologic and chemical evaluation of the ground-water resources of northwest Elkhart County, Indiana
Thomas E. Imbrigiotta, Angel Martin Jr.
1981, Water-Resources Investigations Report 81-53
A 3-year study in northwest Elkhart County, Indiana, was done to (1) de-fine the general flow and quality of water in the outwash aquifer system, (2) determine if a well field proposed for a site at the Elkhart Municipal Airport would draw leachate from the Himco landfill, and (3) define...

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...
Selected hydrologic relationships for Soldier Creek, northeastern Kansas
William J. Carswell Jr.
1981, Water-Resources Investigations Report 81-8
Hydrologic data from Soldier Creek basin were compared with relations from statewide data. The quantity and quality of streamflow were affected mostly by soils, slopes, and land use. Average annual precipitation during the study (196476) was 35.12 inches, or 2.3 percent greater than the long-term (1929-76) average. The average streamflow...

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...
