Flood-plain delineation for Cameron Run Basin, Fairfax County-Alexandria City, Virginia
Pat L. Soule
1976, Open-File Report 76-443
Flood-Plain Delineation for Cameron Run Basin Water-surface profiles of the 25-, 50-, and 100-year recurrence interval discharges have been computed for all streams and reaches of channels in Fairfax County, Virginia, having a drainage area greater than 1 square mile except for Dogue Creek, Little Hunting Creek, and that part...
Water and stream-sediment sampling techniques for use in uranium exploration
Karen J. Wenrich-Verbeek
1976, Open-File Report 76-77
Methods of sampling water and stream sediments for uranium were established in this study. Water samples should be taken using a US DH-48 water sampler across the stream channel and should be filtered and acidified in situ. Stream sediments should be taken as a composite sample up and across the...
The effects of ground-water development on the water supply in the Post Headquarters area, White Sands Missile Range, New Mexico
T. E. Kelly, Glenn A. Hearne
1976, Open-File Report 76-277
Water-level declines in the Post Headquarters area, White Sands Missile Range, N. Mex., have been accompanied by slight but progressive increases in the concentration of dissolved solids in water withdrawn from the aquifer. Projected water-level declines through 1996 are estimated from a digital simulation model to not exceed 200 feet...
Use of an airborne Fraunhofer line discriminator for the detection of solar stimulated luminescence
Robert D. Watson, William R. Hemphill
1976, Open-File Report 76-202
Luminescence is the property of some materials to emit light when excited by external stimuli such as ultraviolet or visible light or by chemical or mechanical action. The Fraunhofer line discriminator (FLO) is an airborne electro-optical device which operates as a non-imaging radiometer and permits detection of solar stimulated luminescence...
A brief hydrologic appraisal of the July 3-4, 1975, flash flood in Las Vegas Valley, Nevada
T. L. Katzer, Patrick A. Glancy, Lynn Harmsen
1976, Open-File Report 76-100
Heavy thunderstorm precipitation on the afternoon of July 3, 1975, between metropolitan Las Vegas and the mountains to the south, west, and north, caused flash flooding in the city area. Total storm precipitation equaled or exceeded 3 inches (76 mm) in some areas. The total storm yield on the area...
Chemical characteristics of the major thermal springs of Montana
Robert H. Mariner, T. S. Presser, William C. Evans
1976, Open-File Report 76-480
Twenty-one thermal springs in western Montana were sampled for chemical, isotope, and gas compositions. Most of the springs issue dilute to slightly saline sodium-bicarbonate waters of neutral to slightly alkaline pH. A few of the springs issue sodium-mixed anion waters of near neutral pH. Fluoride concentrations are high in most...
A summary of petroleum potential, environmental geology, and the technology, time frame, and infrastructure for exploration and development of the western Gulf of Alaska
Roland E. von Huene, Arnold H. Bouma, George Moore, Monty A. Hampton, Rodney Smith, Gordon Dolton
1976, Open-File Report 76-325
This summary of the regional geology, petroleum potential, geologic hazards and time frame for exploration of the western Gulf of Alaska has been written to aid the Bureau of Land Management in preparing the Draft Environmental Impact Statement. A preliminary version was written in Sept., 1975.(von Huene and others, 1975)...
Water availability, quality, and use in Alaska
G. O. Balding
1976, Open-File Report 76-513
The Alaska Water Assessment, sponsored by the Water Resources Council, is a specific problem analysis for Alaska of the National Assessment of Water and Related Land Resources. The assessment addresses water and water-related land problems, present and future. It was felt that a supplementary report, as a part of the...
Reconnaissance of ground-water resources of the Squaxin Island Indian Reservation, Washington
W. E. Lum II, Kenneth Lyle Walters
1976, Open-File Report 76-382
A supply of fresh ground water for the Squaxin Island Indian Reservation exists in saturated deposits underlying the 3.09-square-mile island, whereas surface-water supplies are practically nonexistent. Four test wells tapped a water-hearing zone of sand and gravel and had yields ranging from 27 to 170 gallons per minute, with drawdowns...
Ground-water hydrology of the Cocoa well-field area, Orange County, Florida
C. H. Tibbals, J.M. Frazee
1976, Open-File Report 75-676
The city of Cocoa, Brevard County, Florida, supplies water for much of central Brevard County including Cape Kennedy and Patrick Air Force Base. The water supply is obtained from a well field in east Orange County. Many of the easternmost wells in that well field yield salty water (chloride concentration...
Floods in Pennsylvania: A manual for estimation of their magnitude and frequency
Herbert N. Flippo Jr.
1976, Open-File Report 76-391
Regression equations are provided for estimation of flood magnitude and frequency on unregulated and unurbanized streams in Pennsylvania. Frequency-discharge profiles are shown for regulated reaches on eleven major streams. These regression equations and discharge profiles enable the design engineer to estimate flood-frequency characteristics for almost all streams that drain more...
Integration of geological remote-sensing techniques in subsurface analysis
James V. Taranik, Charles M. Trautwein
1976, Open-File Report 76-402
Geological remote sensing is defined as the study of the Earth utilizing electromagnetic radiation which is either reflected or emitted from its surface in wavelengths ranging from 0.3 micrometre to 3 metres. The natural surface of the Earth is composed of a diversified combination of surface cover types, and geologists...
Ground water in Minnesota
Gerald F. Lindholm, Ralph F. Norvitch
1976, Open-File Report 76-354
Ground water is the major source of water supply in Minnesota. The quantity, quality, and availability vary greatly throughout the State. This study describes the State's ground-water resources as found in each of seven major drainage basins. Water is obtained from Quaternary glacial deposits and bedrock aquifers. Most supplies are from...
