Quaternary geologic map of the Blue Ridge 4° x 6° quadrangle, United States
Alan D. Howard, Robert E. Behling, Walter H. Wheeler, Raymond B. Daniels, W. C. Swadley, Gerald M. Richmond, Richard P. Goldthwait, David S. Fullerton, William D. Sevon, Robert A. Miller, Charles A. Bush
Gerald M. Richmond, David S. Fullerton, Ann Coe Christiansen, editor(s)
1991, IMAP 1420(NJ-17)
This map is part of the Quaternary Geologic Atlas of the United States (I-1420). It was first published as a printed edition in 1986. The geologic data have now been captured digitally and are presented here along with images of the printed map sheet and component parts as PDF files....
Hydrogeology and ground-water flow in the carbonate rocks of the Little Lehigh Creek basin, Lehigh County, Pennsylvania
R. A. Sloto, L.D. Cecil, L.A. Senior
1991, Water-Resources Investigations Report 90-4076
The Little Lehigh Creek basin is underlain mainly by a complex assemblage of highly-deformed Cambrian and Ordovician carbonate rocks. The Leithsville Formation, Allentown Dolomite, Beekmantown Group, and Jacksonburg Limestone act as a single hydrologic unit. Ground water moves through fractures and other secondary openings and generally is under water-table conditions....
Hydrologic provinces of Michigan
S. J. Rheaume
1991, Water-Resources Investigations Report 91-4120
This report presents the results of a study by the U.S. Geological Survey, in cooperation with the Michigan Department of Natural Resources, Geological Survey Division, to describe the statewide hydrologic variations in Michigan's water resources. Twelve hydrologic provinces, which are based on similarities in aquifer lithology, yield, recharge, and ground-water-...
Low-flow characteristics of Kentucky streams
K.J. Ruhl, G. R. Martin
1991, Water-Resources Investigations Report 91-4097
Low-flow characteristics were determined for 136 continuous-record and 212 low-flow partial-record streamflow gaging stations in Kentucky. Low-flow frequency curves were developed for the continuous-record gaging stations from daily mean streamflows for unregulated periods of 10 years or more. Through graphical correlation with data from one or more of the continuous-record...
The computer program estimate trend (ESTREND), a system for the detection of trends in water-quality data
Terry L. Schertz, Richard B. Alexander, Dane J. Ohe
1991, Water-Resources Investigations Report 91-4040
Computerized statistical and graphical procedures were developed for use in U.S. Geological Survey (USGS) investigations of trend in stream water-quality data. These procedures, identified as EStimate TREND (ESTREND), are described in this paper to assist USGS investigators involved in multiple-station studies of water-quality trends. Additional discussion focuses on certain statistical...
A pilot study for delineation of areas contributing water to wellfields at Jackson, Tennessee
R. E. Broshears, J. F. Connell, N. C. Short
1991, Water-Resources Investigations Report 89-4201
The U.S. Geological Survey, in cooperation with the Tennessee Department of Health and Environment, Division of Groundwater Protection, and the Jackson Utility Division, conducted a pilot study to determine data needs and the applicability of four methods for the delineation of wellhead protection areas. Jackson Utility Division in Jackson, Madison...
National water-quality assessment program : the Albemarle- Pamlico drainage
O. B. Lloyd Jr., C.R. Barnes, M. D. Woodside
1991, Open-File Report 91-156
In 1991, the U.S. Geological Survey (USGS) began to implement a full-scale National Water-Quality Assessment (NAWQA) program. Long-term goals of the NAWQA program are to describe the status and trends in the quality of a large, representative part of the Nation's surface- and ground-water resources and to provide a sound,...
Records of wells, drillers' logs, water-level measurements, and chemical analyses of ground water in Brazoria, Fort Bend, and Waller Counties, Texas, 1985-89
Glenn L. Locke
1991, Open-File Report 90-588
Data for water wells and ground water in Brazoria, Fort Bend, and Waller Counties were collected during 1985-89 by the U.S. Geological Survey. This report presents a compilation of records for 32 wells in Brazoria County, 19 wells in Fort Bend County, and 16 wells in Waller County. Drillers' logs...
Records of wells, drillers' logs, water-level measurements, and chemical analyses of ground water in Harris and Galveston Counties, Texas, 1984-89
L.S. Coplin, Al Campodonico
1991, Open-File Report 90-598
Data for water wells and ground water in Harris and Galveston Counties were collected during 1984-89 by the U.S. Geological Survey. This report presents a compilation of records for 243 wells in Harris and Galveston Counties and drillers' logs for 174 of these wells. Water-level data and chemical-quality data of...
Documentation of a heat and water transfer model for seasonally frozen soils with application to a precipitation-runoff model
Douglas G. Emerson
1991, Open-File Report 91-462
A model that simulates heat and water transfer in soils during freezing and thawing periods was developed and incorporated into the U.S. Geological Survey's Precipitation-Runoff Modeling System. The transfer of heat 1s based on an equation developed from Fourier's equation for heat flux. Field capacity and infiltration rate can vary...
Streamflow entering and leaving Lake Bemidji, Beltrami County, Minnesota, July 1987 through September 1989
M.R. Have
1991, Open-File Report 91-499
The U.S. Geological Survey, in cooperation with the Minnesota Department of Natural Resources, operated three streamflow-gaging stations from July 1987 through September 1989 to determine the volume of streamflow entering and leaving Lake Bemidji. Suspended- and bottom-sediment data were also collected at the gaging stations. Two gaging stations were located...
