Streamflow and sediment transport in the Quillayute River basin, Washington
L. M. Nelson
1982, Open-File Report 82-627
From October 1976 to September 1978 the U.S. Geological Survey made a reconnaissance evaluation of the fluvial-sediment transport and documented the natural streamflow characteristics in the Quillayute River basin in northwestern Washington. Most of the flow originates from the tributaries, the Soleduck, Bogachiel, and Calawah Rivers. Flow in the summer...
Vertical movement of ground water under the Merrill Field landfill, Anchorage, Alaska
Gordon L. Nelson, L.L. Dearborn
1982, Open-File Report 82-1016
Shallow groundwater under the Merrill Field sanitary landfill at Anchorage is polluted by leachate. Wells, including three Municipal-supply wells, obtain water from two confined aquifers 100-300 feet beneath the landfill area. Aquifer-test data and information on subsurface geology, ground-water levels, and properties of materials were used to estimate vertical gradients...
Integrated model of the shallow and deep hydrothermal systems in the East Mesa area, Imperial Valley, California
T. David Riney, J.W. Pritchett, L.F. Rice
1982, Open-File Report 82-980
Geological, geophysical, thermal, petrophysical and hydrological data available for the East Mesa hydrothermal system that are pertinent to the construction of a computer model of the natural flow of heat and fluid mass within the system are assembled and correlated. A conceptual model of the full system is developed and...
Proceedings of Workshop XVI; The dynamic characteristics of faulting inferred from recordings of strong ground motion
John Boatwright, editor(s)
1982, Open-File Report 82-591
The strong ground motions radiated by earthquake faulting are controlled by the dynamic characteristics of the faulting process. Although this assertion seems self-evident, seismologists have only recently begun to derive and test quantitative relations between common measures of strong ground motion and the dynamic characteristics of faulting. Interest in this...
Organic geochemistry of sediments on the flanks of Tanner and Cortes banks offshore from southern California
J. B. Rapp, K.A. Kvenvolden
1982, Open-File Report 82-829
Holocene sediment, composed mainly of foram tests, occurs on the flanks of the Tanner and Cortes Banks, offshore southern California. The organic matter in this sediment differs in content and composition from the organic matter in nearby basins. Two sources of hydrocarbons are indicated: terrestrial plants and biodegraded or immature...
Zeolites in the Pine Ridge Indian Reservation, South Dakota
William H. Raymond, Alfred L. Bush, Arthur J. 3rd Gude 3rd
1982, Open-File Report 82-959
Zeolites of possible commercial value occur in the Brule Formation of Oligocene age and the Sharps Formation (Harksen, 1961) of Miocene age which crop out in a wide area in the northern part of the Pine Ridge Indian Reservation. The thickness of the zeolite-bearing Interval and the extent of areas...
Test and calibration of the Digital World-Wide Standardized Seismograph
Jon Peterson, Charles R. Hutt
1982, Open-File Report 82-1087
During the past decade there has been steady progress in the modernization of the global seismograph network operated by the U.S. Geological Survey (USGS). The World-Wide Standardized Seismograph Network (WWSSN) has been augmented by new stations with advanced instrumentation, including the Seismic Research Observatories (SRO) and the modified High-Gain Long-Period...
Sediment and channel-geometry investigations for the Kansas River bank stabilization study, Kansas, Nebraska, and Colorado
W. R. Osterkamp, R.E. Curtis, H.G. Crowther
1982, Open-File Report 81-128
Analysis of hydrologic data from the Kansas River basin suggests that the channels of the lower Solomon, Saline, and Smoky Hill Rivers have narrowed and stabilized as a result of construction of upstream reservoirs. The Kansas River channel, however, remains relatively unstable and locally active. Streamflow regulation and sediment trapping...
Ground-water levels in Wyoming, 1971 through part of 1980
Jess O. Ragsdale
1982, Open-File Report 82-859
Ground-water levels are measured periodically in a network of about 280 observation wells in Wyoming, mostly in areas where ground water is used in large quantities for irrigation or municipal purposes. The program is conducted by the U.S. Geological Survey in cooperation with the Wyoming State Engineer and the city...
Two BASIC computer programs for the determination of in situ stresses using the CSIRO hollow inclusion stress cell and the USBM borehole deformation gage
W. K. Smith
1982, Open-File Report 82-489
The mathematical method of determining in-situ stresses by overcoring, using either the U.S. Bureau of Mines Borehole Deformation Gage or the Commonwealth Scientific and Industrial Research Organisation Hollow Inclusion Stress Cell, is summarized, and data reduction programs for each type of instrument, written in BASIC, are presented. The BASIC programs...
Design concepts for a Global Telemetered Seismograph Network
Jon Peterson, Nicholas A. Orsini
1982, Open-File Report 82-703
This study represents a first step in developing an integrated, real-time global seismic data acquisition system a Global Telemetered Seismograph Network (GTSN). The principal objective of the GTSN will be to acquire reliable, high-quality, real-time seismic data for rapid location and analysis of seismic events. A secondary, but important, objective...
Flood of June 15, 1981, in Great Bend and vicinity, central Kansas
R.W. Clement, D.G. Johnson
1982, Water-Resources Investigations Report 82-4123
Torrential precipitation, as much as 20 inches in 12 hours, resulted in unprecedented flooding on Dry Walnut Creek in southwestern Barton County, central Kansas. Runoff from the storm caused extensive flooding in the town of Great Bend on June 15, 1981. Estimates of total damages exceeded $42 million. Measurements of...
