Geology and water resources of Owens Valley, California
Kenneth J. Hollett, Wesley R. Danskin, William F. McCaffrey, Caryl L. Walti
1991, Water Supply Paper 2370-B
Owens Valley, a long, narrow valley located along the east flank of the Sierra Nevada in east-central California, is the main source of water for the city of Los Angeles. The city diverts most of the surface water in the valley into the Owens River-Los Angeles Aqueduct system, which transports...
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...
Records of wells, drillers' logs, water-level measurements, and chemical analyses of ground water in Chambers, Liberty, and Montgomery Counties, Texas, 1985-89
Glenn L. Locke
1991, Open-File Report 90-594
Data for water wells and ground water in Chambers, Liberty, and Montgomery Counties were collected during 1985-89 by the U.S. Geological Survey. This report presents a compilation of records for 4 wells in Chambers County, 8 wells in Liberty County, and 64 wells in Montgomery County. Drillers' logs of 60...
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...
Simulation of ground-water flow in the coastal plain aquifer system of North Carolina
G. L. Giese, J. L. Eimers, R. W. Coble
1991, Open-File Report 90-372
A 3-D finite difference digital model was used to simulate groundwater flow in the 25,000 sq mi aquifer system of the North Carolina Coastal Plain. The model was developed from a geohydrologic framework that is based on an alternating sequence of 10 aquifers and 9 confining units, which comprise a...
Definitions of database files and fields of the Personal Computer-Based Water Data Sources Directory
J. Wayne Green
1991, Open-File Report 91-184
This report describes the data-base files and fields of the personal computer-based Water Data Sources Directory (WDSD). The personal computer-based WDSD was derived from the U.S. Geological Survey (USGS) mainframe computer version. The mainframe version of the WDSD is a hierarchical data-base design. The personal computer-based WDSD is a relational...
Water resources data, Alabama, water year 1990
J. L. Pearman, F.C. Sedberry, V.E. Stricklin, P.W. Cole
1991, Water Data Report AL-90-1
The Water Resources Division of the U.S. Geological Survey, in cooperation with State and Federal agencies, obtains a large amount of data pertaining to the water resources of Alabama each water year. These data, accumulated during many water years, constitute a valuable data base for developing an improved understanding of...
Tributary-stream infiltration in Marsh Creek Valley, north-central Pennsylvania
John H. Williams
1991, Water-Resources Investigations Report 90-4052
The geohydrology of infiltration from five tributary streams along a 3.6-mile reach of Marsh Creek valley in north-central Pennsylvania was investigated during 1983-85. Marsh Creek valley is underlain by up to 100 feet of stratified drift that overlies Devonian bedrock. The stratified drift is overlain by up to 30 feet...
