Hydrologic data for the south-central area, Nebraska
P.A. Bartz, J. M. Peckenpaugh
1986, Open-File Report 86-246
Hydrologic data were compiled for the South-Central hydrogeology study, which covers an area of approximately 5,600 square miles in south-central Nebraska. Data pertain to the groundwater, surface water, climate, land use, and pumpage and precipitation at water use sites in the study area. Groundwater data include water level elevations from...
Delineation and description of the regional aquifers of Tennessee; basal sandstone aquifer west of the Valley and Ridge Province
J. V. Brahana, M. W. Bradley, J. A. Macy, Dolores Mulderink
1986, Open-File Report 82-762
The basal sandstone aquifer is believed to underlie most of Tennessee west of the Valley and Ridge Province. It is a Cambrian sandstone that overlies the granites of the Precambrian basement complex. The basal sandstone is a poorly known resource defined only by 14 data points (wells) for the entire...
Method for estimating low-flow characteristics of ungaged streams in Indiana
Leslie D. Arihood, Dale R. Glatfelter
1986, Open-File Report 86-323
Equations for estimating the 7-day, 2-year and 7-day, 10-year low flows at sites on ungaged streams are presented. Regression analysis was used to develop equations relating basin characteristics and low-flow characteristics at 82 gaging stations. Significant basin characteristics in the equations are contributing drainage area and flow-duration ratio, which is...
Delineation and description of the regional aquifer systems of Tennessee; Cumberland Plateau aquifer system
J. V. Brahana, J. A. Macy, Dolores Mulderink, Dawn Zemo
1986, Open-File Report 82-338
The Cumberland Plateau aquifer system consists of Pennsylvanian sandstones, conglomerates, shales, and coals which underlie the Cumberland Plateau in Tennessee. Major water-bearing zones occur within the sandstones and conglomerates in interconnected fractures. The water-bearing formations are separated by shale and siltstone that retard the vertical circulation of ground water, The...
Activities of the Water Resources Division, California District, in the 1985 fiscal year
P. W. Anttila (compiler)
1986, Open-File Report 86-244
This report summarizes the progress of water-resources studies in California by the U.S. Geological Survey during the fiscal year 1985. Much of the work was done in cooperation with the State and local agencies. Additional supporting funds were transferred from other Federal agencies or appropriated directly to the Geological Survey....
