1975, Water Data Report WV-74-1
Water resources data for the 1974 water year for West Virginia including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, records of water-quality data on the chemical and physical characteristics of surface water, and records of ground-water levels at index wells are given in...
Mineralization in the Uyaijah-Thaaban area, west-central part of the Uyaijah ring structure, Kingdom of Saudi Arabia
F. C. Dodge, A. M. Helaby
1975, Open-File Report 75-175
Anomalous amounts of tungsten, molybdenum, and bismuth were found previously in surficial debris collected from the Uyaijah-Thaaban area in the west-central part of the Precambrian Al Uyaijah ring structure. The area is mostly underlain by quartz monzonite. Countless quartz veins ranging from a knife edge to more than 3 m...
Hydrology for land-use planning: The Hillside area, Anchorage, Alaska
Larry L. Dearborn, William W. Barnwell
1975, Open-File Report 75-105
Rapid residential growth of the Hillside area, Anchorage, Alaska, may cause depletion of aquifers and a change in quality of water resources as a result of extensive development of small-lot tracts. Ground-water yields are low and may be locally inadequate for single family requirements where wells produce from bedrock in...
Heavy mineral prospecting in Pakistan
Karl W. Stauffer, James Alfred Calkins
1975, Open-File Report 75-359
Heavy-mineral prospecting is a method of tracing potential ore minerals to their source by systematically examining the heavy minerals of stream sands. The heavy minerals are partially concentrated in the field by panning. In the laboratory the heavy minerals are further concentrated by floating off the quartz and feldspar in...
Erosion and sediment transport in the Owens River near Bishop, California
Rhea P. Williams
1975, Water-Resources Investigations Report 75-49
Closure of Pleasant Valley Dam in 1954 has almost eliminated the supply of gravel to the 16-mile (25.7-kilometre) study reach of the Owens River. Because of armoring of the channel, scour has been limited to approximately 1 foot (0.3 metre) in the upper 2.3 miles (3.7 kilometres).This report presents information...
