Method for estimating historical irrigation requirements from ground water in the High Plains in parts of Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming
Frederick J. Heimes, Richard R. Luckey
1982, Water-Resources Investigations Report 82-40
Historical information on ground-water pumpage for irrigation is required for use with a computer model of the High Plains aquifer. Available historical data on ground-water pumpage in the High Plains were inadequate for use with the computer model. Consequently, a method was developed to estimate historical pumpage data.Two principal components...
Hydrology of the sand-and-gravel aquifer, southern Okaloosa and Walton Counties, northwest Florida
L. R. Hayes, D. E. Barr
1982, Water-Resources Investigations Report 82-4110
The sand-and-gravel aquifer in southern Okaloosa and Walton Counties, northwest Florida, extends from land surface to depth of 50 to 150 feet. Intervening layers of clay generally separate the aquifer into an unconfined surficial zone, composed principally of fine to medium sand, and a lower confined zone, consisting of variable...
Preliminary evaluation of the ground-water-flow system in the Twin Cities Metropolitan area, Minnesota
John H. Guswa, Donald I. Siegel, Daniel C. Gillies
1982, Water-Resources Investigations Report 82-44
A preliminary quasi-three-dimensional finite-difference ground-water-flow model of the seven-county Twin Cities Metropolitan area was constructed and used to evaluate parameter sensitivity and adequacy of available data. Fourteen geologic units that underlie the study area were grouped into nine hydr,bgeologic units and were incorporated into a five-layer model. The layers in...
Evaluation of sediment yield and sediment data-collection network in the Piceance basin, northwestern Colorado
J. E. Kircher, Paul Von Guerard
1982, Water-Resources Investigations Report 82-4046
Statistical relationships were developed between suspended-sediment discharge and several regional factors of climate, physiography, and land use in the Piceance basin, northwestern Colorado. The purpose of the study was to evaluate the existing sediment collection network, especially in regard to detecting changes in suspended-sediment discharge due to the development in...
Evaluation of a predictive ground-water solute-transport model at the Idaho National Engineering Laboratory, Idaho
Barney D. Lewis, Flora J. Goldstein
1982, Water-Resources Investigations Report 82-25
Aqueous chemical and radioactive wastes discharged to shallow ponds and to shallow or deep wells on the Idaho National Engineering Laboratory (INEL) since 1952 have affected the quality of the ground water in the underlying Snake River Plain aquifer. The aqueous wastes have created large and laterally dispersed concentration plumes...
Appraisal of ground-water quality near wastewater-treatment facilities, Glacier National Park, Montana
Joe A. Moreland, Wayne A. Wood
1982, Water-Resources Investigations Report 82-4
Water-level and water-quality data were collected from monitoring wells at wastewater-treatment facilities in Glacier National Park. Five additional shallow observation wells were installed at the Glacier Park Headquarters facility to monitor water quality in the shallow ground-water system.Water-level, water-quality, and geologic information indicate that some of the initial monitoring wells...
Water resources data for Hawaii and other Pacific areas: Volume 1. Hawaii
Water Resources Division, U.S. Geological Survey
1982, Water Data Report HI-81-1
Volume 1 of water resources data for the 1981 water year for Hawaii and other Pacific Areas consists of records of stage, discharge, and water quality of streams; and water levels and water quality in wells and springs. This report contains discharge records for 106 gaging stations; water quality for...
Johnstown-western Pennsylvania storms and floods of July 19-20, 1977
L. Ray Hoxit, Robert A. Maddox, Charles F. Chappell, Stan A. Brua
1982, Professional Paper 1211
Widespread thunderstorms associated with two major squall lines, moved across Pennsylvania between the afternoon of July 19 and morning of July 20, 1977. The western part of outflow boundary produced by the second line became almost stationary in western Pennsylvania and resulted in 6 to 9 hours of nearly continuous...
Saturated thickness of the High Plains regional aquifer in 1980, northwestern Oklahoma
John S. Havens
1982, Open-File Report 82-760
During 1978, the U.S. Geological Survey began a 5-year study of the High Plains regional aquifer system to provide hydrologic information for evaluation of the effects of long-term development of the aquifer and to develop computer models for prediction of aquifer response to alternative changes in ground-water management (Weeks, 1978)....
Potentiometric-surface map of water in the Lakota Formation and equivalent units in the northern Great Plains area of Montana
Gary Wayne Levings
1982, Open-File Report 82-563
The potentiometric surface of water in the lower Cretaceous Lakota Formation and equivalent units (Cut Bank Sandstone Member , Sunburst Sandstone Member, and Moulton Member of Kootenai formation; Third Cat Creek sandstone of Kootenai Formation; Pryor Conglomerate Member of Kootenai Formation) is shown on a base at a scale of...
