Preliminary map showing the difference between the potentiometric surfaces of the Aquia Aquifer of September 1982 and September 1984 in southern Maryland
Frederick K. Mack, Judith C. Wheeler, Stephen E. Curtin, David C. Andreasen
1985, Water-Resources Investigations Report 85-4339
The potentiometric map is highlighted with indications concerning: (1) outcrop areas of the Aquia aquifer; (2) the potentiometric contour of the aquifer; (3) observation and/or supply wells yielding < 10,000 gallons/day (gpd); and (4) other supply wells with yields > 10,000 gpd. (Lantz-PTT)...
Seismic-refraction study of suspected drift-filled bedrock valleys in Ramsey County, Minnesota
D. G. Woodward
1985, Water-Resources Investigations Report 85-4107
Seismic-refraction surveys were made across suspected buried, drift-filled bedrock valleys believed to underlie two sites of known ground-water contamination the Twin Cities Army Ammunition Plant (TCAAP) near New Brighton and the former Koppers Coke Plant in St. Paul, Ramsey County, Minnesota. Refraction data were collected along two lines at each...
Analysis of surface-water data network in Kansas for effectiveness in providing regional streamflow information
K.D. Medina, Gary D. Tasker
1985, Open-File Report 85-680
The surface water data network in Kansas was analyzed using generalized least squares regression for its effectiveness in providing regional streamflow information. The correlation and time-sampling error of the streamflow characteristic are considered in the generalized least squares method. Unregulated medium-flow, low-flow and high-flow characteristics were selected to be representative...
Hydrologic data in small watersheds, coal-mining region, west-central Indiana, October 1980 to June 1983, and instrumentation and methods of collecting the data
D.E. Renn, R.F. Duwelius, C.R. Keeton, J.W. Tyler Jr.
1985, Open-File Report 85-402
Hydrologic data were collected in seven watersheds ranging in area from 0.11 to 4.87 square miles. Principal uses of land include farming in two of the watersheds, farming and forestry in one, farming and unreclaimed surface coal mines in one, reclaimed surface coal mines in two, and an unreclaimed surface...
Reconnaissance of mine drainage in the coal fields of eastern Pennsylvania
D.J. Growitz, L.A. Reed, M.M. Beard
1985, Water-Resources Investigations Report 83-4274
Anthracite has been extensively mined in four areas of eastern Pennsylvania. Almost all underground mining in the four areas, the Northern, Eastern Middle, Western Middle, and Southern Fields, has been discontinued and many mines are abandoned and flooded. Precipitation on much of the 408 square miles of coal fields infiltrates...
The surficial aquifer in Pinellas County, Florida
K.W. Causseaux
1985, Water-Resources Investigations Report 84-4289
The surficial aquifer in Pinellas County, Florida, contains potable water throughout most of the county and is a potential source of water to augment the public supply that is presently imported from adjacent counties. The county accounts for 38 percent of the public supply consumption of ground water in the...
Hydrogeology of the southwestern part of the Town of Hempstead, Nassau County, New York
R.K. Krulikas
1985, Water-Resources Investigations Report 85-4288
The groundwater resources of the southwestern part of the Town of Hempstead in Nassau County, NY were investigated in 1984. The area studied encompasses 85 sq mi, or 68% of the town 's 125-sq mi area. The groundwater reservoir underlying the area consists of unconsolidated gravel, sand, silt, and clay...
Documentation of a numerical code for the simulation of variable density ground-water flow in three dimensions
L.K. Kuiper
1985, Water-Resources Investigations Report 84-4302
A numerical code is documented for the simulation of variable density time dependent groundwater flow in three dimensions. The groundwater density, although variable with distance, is assumed to be constant in time. The Integrated Finite Difference grid elements in the code follow the geologic strata in the modeled area. If...
Water quality of the North Platte River, east-central Wyoming
L. R. Larson
1985, Water-Resources Investigations Report 84-4172
This report is a statistical summary of 40 different constituents and physical characteristics that describe the water quality of the North Platter River between Alcova Dam and Orin, Wyoming, a distance of 143 river miles. Data from seven stations are summarized for 1970-79. Water entering the North Platte River upstream...
