Petrology of Potomac Group sands in Fairfax County, Virginia
Roy C. Lindholm
1978, Open-File Report 78-512
The Potomac Group sands sampled in Fairfax County are dominantly microcline-rich lithic arkoses. Quartz averages 59%, microcline 25%, plagioclase less than 1% and lithic grains 16%. Most sands are texturally submature and medium grained. Microcline is somewhat more abundant in the deeper beds in the subsurface than in the shallow...
Interim report on streamflow, sediment discharge, and water quality in the Calabazas Creek Basin, Santa Clara County, California
J. M. Knott, G.L. Pederson, Robert F. Middelburg
1978, Water-Resources Investigations Report 78-2
Streamflow, sediment-discharge, and water-quality data are being collected in the Calabazas Creek basin, Santa Clara County, Calif., to determine annual water and sediment discharge at base-line conditions that are representative of a basin prior to urbanization. Results of the first 3 years of the study (1973-75) are given in this...
Chemical and physical quality of selected public water supplies in Florida, August-September 1976
G. A. Irwin, Henry G. Healy
1978, Water-Resources Investigations Report 78-21
Results of a 1976 water-quality reconnaissance made by the U.S. Geological Survey indicated that, with few exceptions, all public water supplies in Florida are of high quality and meet the standards set forth in the National Interim Primary Drinking Water Regulations. Occasionally the concentrations of fluoride, turbidity, cadmium, chromium, and...
Supplementary hydraulic analysis of proposed bridge site on Mohawk River, Whitesboro, New York
Richard Lumia
1978, Open-File Report 78-348
As a supplement to a 1975 report, titled "Floodflow Characteristics at Proposed Bridge Site on Mohawk River, Whitesboro, New York," by Bernard Dunn (U.S. Geological. Survey open-file report), in which the hydraulic effects of two alternative highway plans during a large-magnitude flood were evaluated, a hydraulic analysis was made for...
Water-resources investigations of the U.S. Geological Survey in Wyoming, fiscal year 1978
F. C. Boner
1978, Open-File Report 78-239
This report contains lists of streamflow and reservoir stations, peak-flow partial-record stations, chemical-quality stations, sediment stations, and observation wells where water levels are measured in Wyoming. The locations of the basic-data sites are shown on maps. Thirty-two water-resources appraisal projects in Wyoming are also described, including many that are related...
Terrain-analysis procedures for modeling radar backscatter
Gerald G. Schaber, Richard J. Pike, Graydon Lennis Berlin
1978, Open-File Report 79-1088
The collection and analysis of detailed information on the surface of natural terrain are important aspects of radar-backscattering modeling. Radar is especially sensitive to surface-relief changes in the millimeter- to-decimeter scale four conventional K-band (~1-cm wavelength) to L-band (~25-cm wavelength) radar systems. Surface roughness statistics that characterize these changes in...
Ground-water availability in the Hayes-Red Willow, Frenchman, and Meeker-Driftwood irrigation districts, southwest Nebraska
E.G. Lappala, P.F. Hemphill, R.E. Booker
1978, Open-File Report 78-461
Surface-water supplies are diminishing in the Hitchcock-Red Willow and Frenchman Valley Irrigation Districts in southwest Nebraska. Stream depletions due to ground-water withdrawals upstream from Enders Reservoir (northwest of the study area) have resulted in a shortage of about 8,700 acre-feet per year. The availability of ground water to supply part...
Water resources of the Kodiak-Shelikof subregion, south-central Alaska
Stanley H. Jones, R. J. Madison, Chester Zenone
1978, Hydrologic Atlas 612
Hydrologic data for the Kodiak-Shelikof subregion of south-central Alaska are summarized to provide a basis for planning water resources development, identifying water problems and evaluating existing water quality and availability. Average annual precipitation, measured at a few coastal locations in this maritime climatic zone, ranges from 23 to 127 inches....
Map showing saturated thickness of unconsolidated aquifer in southwestern Kansas, January 1978
Marilyn E. Pabst
1978, Open-File Report 78-969
The principal aquifer in the 13-county area of southwestern Kansas occurs in the heterogeneous, unconsolidated alluvial deposits of Tertiary and Quaternary age.  The main body of this ground-water reservoir is designated as the unconsolidated aquifer.The map showing the saturated thickness of deposits in the unconsolidated aquifer was prepared by comparing...
Water resources data, Wyoming, water year 1977; Volume 1. Missouri River basin
Water Resources Division, U.S. Geological Survey
1978, Water Data Report WY-77-1
Water resources data for the 1977 water year for Wyoming consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of wells. This report, in two volumes, contains discharge records for 214 gaging stations;...
