Selected hydrologic data, Arkansas River basin, Pueblo and southeastern Fremont Counties, Colorado, 1975-80
Doug Cain, Patrick Edelmann
1980, Open-File Report 80-1185
Selected hydrologic data collected in 1975-80 as part of water-quality investigations by the U.S. Geological Survey in Pueblo and southeastern Fremont Counties, Colo., are presented in this report. The data, in tabular form, consist of streamflow-discharge measurements for 33 sites, channel-geometry measurements for 97 sites, traveltime data for 12 sites,...
Hurricane Frederic tidal floods of September 12-13, 1979, along the Gulf Coast, Pine Beach, St. Andrews Bay, and Fort Morgan quadrangles, Alabama
John C. Scott, Larry R. Bohman
1980, Hydrologic Atlas 634
Shown on a topographic map are floodmark elevations and approximate areas flooded by Hurricane Frederic tides of September 12-13, 1979, along the shores of St. Andrews Bay, Mobile Bay, and Bon Secour Bay from Fort Morgan eastward to about four miles east of Gasque, Ala. The storm tide went completely...
Hole-to-surface resistivity measurements at Salt Valley, Utah
Jeffrey J. Daniels, James H. Scott
1980, Open-File Report 80-981
Evaporites are an important potential medium for the storage of radioactive wastes. In order to ascertain the viability of a proposed waste isolation site, it is necessary to study its geology without extensive drilling that might destroy its structural integrity. Hole-to-surface and hole-to-hole geophysical measurements can be useful in supplementing...
Mathematical model of the Tesuque aquifer system underlying Pojoaque River basin and vicinity, New Mexico
Glenn A. Hearne
1980, Open-File Report 80-1023
A three-dimensional digital model of ground-water flow was constructed to represent the dipping anisotropic beds of the Tesuque aquifer system underlying the Pojoaque River basin and vicinity, New Mexico. Simulations of steady-state conditions and historical ground-water withdrawals were consistent with observed data. The model was used to simulate the response...
Baseline water quality of Schmidt, Hornbeam, and Horseshoe Lakes, Dakota County, Minnesota
G. A. Payne
1980, Water-Resources Investigations Report 80-3
Three lakes in Dakota County were sampled five times during an 18-month period to determine baseline water quality prior to construction of an interstate highway. Results of physical measurements and chemical analyses showed that the lakes were shallow, nonstratified, and nutrient enriched. Considerable seasonal variations in dissolved solids, nutrient, and...
Summary appraisals of the nation's ground-water resources – Caribbean region
Fernando Gómez-Gómez, James E. Heisel
1980, Professional Paper 813-U
The Caribbean Region consists of the Commonwealth of Puerto Rico (8,990 km2 (square kilometers)) and the U.S. Virgin Islands (350 km2). The mean annual precipitation varies locally from a high of 5,000 mm (millimeters) to a low of 730 mm. Maximum precipitation occurs within the peaks of Sierra de Luquillo,...
Estimating the costs of landslide damage in the United States
Robert W. Fleming, Fred A. Taylor
1980, Circular 832
Landslide damages are one of the most costly natural disasters in the United States. A recent estimate of the total annual cost of landslide damage is in excess of $1 billion {Schuster, 1978}. The damages can be significantly reduced, however, through the combined action of technical experts, government, and the...
The handling, hazards, and maintenance of heavy liquids in the geologic laboratory
Phoebe L. Hauff, Joseph Airey
1980, Circular 827
In geologic laboratories the organic heavy liquids bromoform, methylene iodide, tetrabromoethane, and clerici compounds have been used for years in mineral separation processes. Because the volume of use of these compounds is low, insufficient data is available on their toxic properties. This report is an attempt to summarize the known...
