1983, Open-File Report 83-131
Safety, defined as 'freedom from danger, risk, or injury,' is difficult to achieve in a laboratory environment. Inherent dangers, associated with water analysis and research laboratories where hazardous samples, materials, and equipment are used, must be minimized to protect workers, buildings, and equipment. Managers, supervisors, analysts, and laboratory support personnel...
Water-resources investigations of the U.S. Geological Survey in Wyoming, fiscal years 1981 and 1982

Reconnaissance geology of the Jabal Dalfa Quadrangle, sheet 21/43 C, Kingdom of Saudi Arabia
Robert C. Greene
1983, Open-File Report 83-333
The Jabal Dalfa quadrangle (sheet 21/43 C) is part of the Najd province in west-central Saudi Arabia. The quadrangle is mostly a plain, tilted gently northeastward, but local inselbergs and two areas of dissected uplands rise as much as 200 m above the plain. Wadi Bishah and Wadi Ranyah terminate...
Report of the annual yield of the Arkansas River basin for the Arkansas River Basin Compact Arkansas-Oklahoma
T.E. Lamb, Martha A. Moore
1983, Open-File Report 83-46
The computed annual yield and deficiency of the subbasins as defined in the Arkansas River Compact, Arkansas-Oklahoma, are given in tables. Actual runoff from the subbasins and depletion caused by major reservoirs in the compact area are also given in tabular form. Monthly, maximum, minimum, and mean discharges are shown...

1983, Open-File Report 83-679
Water and suspended-sediment discharges were measured and bed-material samples were collected during August, 1982, at 9 cross sections along a 800-kilometer reach of the Rio Orinoco. Flows varied from approximately 31,000 to 72,000 cubic meters per second, and sediment discharge varied from approximately 1,600 to 8,000 kilograms per second. The...

1983, Open-File Report 83-85
Magnetotellurics is a geophysical technique which was developed by Cagnaird (1953) and Tikhonov (1950) and later refined by other scientists worldwide. The technique is a method of electromagnetic sounding of the Earth and is based upon the skin depth effect in conductive media. The electric and magnetic fields arising from...
