Preliminary hydrologic budget of the sand-and-gravel aquifer under unstressed conditions: with a section on water-quality monitoring, Pensacola, Florida
Henry Trapp Jr.
1978, Water-Resources Investigations Report 77-96
The sand-and-gravel aquifer is the only freshwater aquifer in southern Escambia County, Fla. Problems related to the development of the aquifer include sustained yield, contamination, and saltwater intrusion. A digital model was applied to the sand-and-gravel aquifer in central and southern Escambia County treating the aquifer 's 'main producing zone...
Determination of peak discharge from rainfall data for urbanized basins, Wichita, Kansas
C.O. Peek, P. R. Jordan
1978, Open-File Report 78-974
Rainfall and runoff data from urbanized drainage basins in the Wichita area, Kansas, were used to evaluate the Soil Conservation Service synthetichydrograph method of computing flood hydrographsfrom rainfall data. The method was tested on six basins where the impervious surface ranged from 11 percent on the least urbanized basin to...
Critical environmental areas program workshops: A synopsis of results
Joseph T. O’Connor, Charles R. Meyers
1978, Open-File Report 78-868
Problems besetting the development of State Critical Environmental Areas Programs were discussed at a series of six workshops sponsored by the Resource and Land Investigations (RALI) Program and Office of Land Use and Water Policy (OLUWP) of the Department of the Interior. The major problems were determined to be: program...
Temperature in streams of New Mexico for the period October 1964 to September 1969
Ralph W. Clement
1978, Water-Resources Investigations Report 78-140
Harmonic equations were developed to describe stream temperatures at 144 sites in New Mexico using periodically observed water temperatures collected from October 1964 through September 1969. The harmonic equations explained at least 80 percent of the variability at 70 of the sites. Standard errors of estimate ranged from 1.3 to...
K-Ar geochronology of the Survey Pass, Ambler River and Eastern Baird Mountains quadrangles, southwestern Brooks Range, Alaska
Donald L. Turner, R. B. Forbes, C.F. Mayfield
1978, Open-File Report 78-254
We report 76 previously unpublished K-Ar mineral ages from 47 metamorphic and igneous rocks in the southwestern Brooks Range. The pattern of radiometric ages is complex, reflecting the complex geologic history of this area. Local and regional radiometric evidence suggests that the southern Brooks Range schist belt has, at least...
Bibliography of the available data on the solubility of silica in water substance
Robert W. Potter, W.L. Marshall, R.O. Fournier, O.I. Martynova
1978, Open-File Report 78-731
The following bibliography represents the currently available experimental data for the solubility of silica in water substance as a function of temperature and pressure. These references were compiled by the silica subcommittee of Working Group IV at the 1977 meeting of LAPS in Moscow. The data summarized in these references...
Preliminary geologic report on the Harris Lake area, northeastern Minnesota
M. P. Foose, Roger W. Cooper
1978, Open-File Report 78-385
Intense faulting and fracturing in the Harris Lake area) northeastern Minnesota are documented by detailed field studies. Faults are identified chiefly by the disruption of mappable layers within sequences of plagioclase and plagioclase-olivine cumulates. Most layers grade from olivine-rich bottoms to plagioclase-rich tops and were probably deposited by density currents....
Premetamorphic hydrothermal origin of the Tungsten Queen vein, Hamme District, North Carolina, as indicated by mineral textures and minor structures
Michael P. Foose, John F. Slack
1978, Open-File Report 78-427
The Hamme Tungsten district is a 13-km long, 2-km wide, northeast-trending belt located in northern Vance County, North Carolina and southern Mecklenburg County, Virginia (Fig. 1). The district contains the largest quartz-wolframite-type vein deposits in the United States. Over 50 tungsten-bearing veins occur in this area (Espenshade, 1947), from which...
Availability of fresh and slightly saline ground water in the basins of westernmost Texas
Joseph Spencer Gates, W. D. Stanley, H.D. Ackermann
1978, Open-File Report 78-663
Significant quantities of fresh ground water occur in the basin fill of the northern Hueco bolson and lower Mesilla Valley and in the Wildhorse Flat, Michigan Flat, Lobo Flat, and Ryan Flat areas of the Salt Basin; and may occur in Red Light Draw, Presidio bolson, and Green River valley....
