Geology and hydrology of the Edwards Aquifer in the San Antonio area, Texas
Robert W. Maclay
1995, Water-Resources Investigations Report 95-4186
The Edwards aquifer, which is the sole source of water for the city of San Antonio, is one of the most permeable and productive carbonate aquifers in the United States. The aquifer is composed of extensively faulted, fractured, and cavernous limestone and dolomite of Early Cretaceous age lying within the...
Estimating heat capacity and heat content of rocks
Eugene C. Robertson, Bruch S. Hemingway
1995, Open-File Report 95-622
New heat-capacity measurements are reported for four rock types; Westerly granite from Bradford, RI, andesite from Lake County, OR, peridotite from Sonoma County, CA, and basalt from the Columbia River Group. Measurements were made on powders of the rocks in the temperature range of 340 to about 1000 K. Our measured...
Depth to water, 1991, in the Rathdrum Prairie, Idaho; Spokane River valley, Washington; Moscow-Lewiston-Grangeville area, Idaho; and selected intermontane valleys, east-central Idaho
Charles E. Berenbrock, M. D. Bassick, T. L. Rogers, S. P. Garcia
1995, Water-Resources Investigations Report 94-4087
This map report illustrates digitally generated depth-to-water zones for the Rathdrum Prairie in Idaho; part of the Spokane River Valley in eastern Washington; and the intermontane valleys of the upper Big Wood, Big Lost, Pahsimeroi, Little Lost, and Lemhi Rivers and Birch Creek in Idaho. Depth to water is 400...
Recharge to the surficial aquifer system in Lee and Hendry counties, Florida
R.K. Krulikas, G. L. Giese
1995, Water-Resources Investigations Report 95-4003
Protection of ground-water recharge areas against contamination is of great interest in Florida, a State whose population depends heavily on ground water and that is experiencing rapid growth. The Florida Legislature is considering implementation of a tax incentive program to owners of high-rate recharge lands that remain undeveloped. High-rate recharge...
Contaminants in the Mississippi River, 1987-92
Robert H. Meade
1995, Circular 1133
Contaminants were measured in the Mississippi River and some of its tributaries between Minneapolis, Minnesota, and the Gulf of Mexico on 10 separate occasions between July 1987 and May 1992. Measurements included contaminants dissolved in the river waters, those adsorbed on sediment particles being transported by the rivers, and contaminants...
Land-cover sampling designs, data-collection procedures, and land-cover data for the Central Nebraska Basins, 1993-94
R. B. Zelt, J. T. Dugan, M.S. Kelley
1995, Open-File Report 95-166
Within the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program, land-cover data are used in characterizing drainage areas upstream from surface-water sampling sites and areas selected for spatially distributed ground-water sampling. During the period of time when the initial 20 NAWQA study study-unit investigations were evaluating existing land-cover data, a...
Selected hydrologic data for urban watersheds in South Carolina, 1983-90
S.W. Logan, M.R. Eckenwiler, L. R. Bohman
1995, Open-File Report 95-351
Rainfall and streamflow data were collected at 23 gaging stations located in urban watersheds in South Carolina from 1983-90. The site selection process and the instrumentation used to collect the data are described. A compilation of rainfall and streamflow data in graphic and tabular form for seven selected events at...
Exploring storm surge
A. B. Tihansky, A. D. Duerr
1995, Open-File Report 95-295
This video provides a thorough discussion of storm surge, one of the most dangerous elements of hurricanes and major storms. This video illustrates basic storm surge principles, shows actual footage of storm surge damage and relates high-water level data collection by the U.S. Geological Survey to the task of recreating...
Ground-water flow and the possible effects of remedial actions at J-Field, Aberdeen Proving Ground, Maryland
W.B. Hughes
1995, Water-Resources Investigations Report 95-4075
J-Field, located in the Edgewood Area of Aberdeen Proving Ground, Md, has been used since World War II to test and dispose of explosives, chemical warfare agents, and industrial chemicals resulting in ground-water, surface-water, and soil contami- nation. The U.S. Geological Survey finite-difference model was used to better understand ground-water...
Preliminary Geologic Map of the Big Pine Mountain Quadrangle, California
J. G. Vedder, Hugh McLean, R. G. Stanley
1995, Open-File Report 95-554
Reconnaissance geologic mapping of the San Rafael Primitive Area (now the San Rafael Wilderness) by Gower and others (1966) and Vedder an others (1967) showed s number of stratigraphic and structural ambiguities. To help resolve some of those problems, additional field work was done on parts of the Big Pine...
