A single-degree-of-freedom model for non-linear soil amplification
Mustafa Ozder Erdik
1979, Open-File Report 79-592
For proper understanding of soil behavior during earthquakes and assessment of a realistic surface motion, studies of the large-strain dynamic response of non-linear hysteretic soil systems are indispensable. Most of the presently available studies are based on the assumption that the response of a soil deposit is mainly due to...
Supplement to floods in the upper Des Moines River basin, Iowa
Albert J. Heinitz
1979, Open-File Report 79-1486
Data on the East Fork Des Moines River for the August 1979 flood between river miles 330.4 and 408.8 is being published as a supplement to the report "Floods in the Upper Des Moines River basin, Iowa" (Schwab, 1970). Elevation profiles of the 1979 flood, along with previously published profiles, are shown in figures...
Organic carbon content of Devonian shale sequence sampled in drill cuttings from eighteen wells in western Pennsylvania
George Edwin Claypool, Allan W. Stone
1979, Open-File Report 79-1665
This report contains results of organic carbon analyses performed by Rinehart Laboratories, Inc., Arvada, Colorado, under contract to the U.S. Geological Survey. The analytical method employs chemical (chromic acid) oxidation of an acid solution containing the rock residue. The detailed analytical specifications are contained in the Rinehart proposal in response...
Water-level predictions for Indian Wells Valley ground-water basin, California, 1978
Michael J. Mallory
1979, Open-File Report 79-254
Ground-water pumpage in Indian Wells Valley, virtually a closed basin in the Mojave Desert of southern California, has increased gradually since 1945 and presently exceeds the long-term mean annual recharge (perennial supply). In order to aid in the understanding and management of the ground-water basin, a digital ground-water model was...
Two oil types on the North Slope of Alaska: implications for future exploration
Leslie B. Magoon, George Edwin Claypool
1979, Open-File Report 79-1649
Forty oil samples from across the North Slope of Alaska have been analyzed by the U.S. Bureau of Mines and the U.S. Geological Survey. Results of these analyses suggest two separate genetic oil types. The first type, the Simpson-Umiat oil type, occurs in reservoir rocks of Cretaceous and Quaternary age...
Ground-water resources of Monroe County, Pennsylvania
Louis D. Carswell, Orville B. Lloyd Jr.
1979, Open-File Report 79-414
Monroe County is on the eastern border of Pennsylvania and includes much of the area popularly called the Poconos. It is an area long used for outdoor recreation and includes a part of the Delaware Water Gap National Recreation Area.Water resources in the county are derived from precipitation. The Lehigh...
A one-dimensional, steady-state, dissolved-oxygen model and waste-load assimilation study for South Fork Wildcat Creek, Clinton County, Indiana
Charles G. Crawford, William G. Wilber, James G. Peters
1979, Open-File Report 79-1074
The Indiana State Board of Health is developing a State water-quality management plan that includes establishing limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in South Fork Wildcat Creek was used to predict alternatives for future waste loadings that would be compatible with Indiana...
Modeling highly transient flow, mass, and heat transport in the Chattahoochee River near Atlanta, Georgia
Harvey E. Jobson, Thomas N. Keefer
1979, Open-File Report 79-270
A coupled flow-temperature model has been developed and verified for a 27.9-km reach of the Chattahoochee River between Buford Dam and Norcross, Ga. Flow in this reach of the Chattahoochee is continuous but highly regulated by Buford Dam, a flood-control and hydroelectric facility located near Buford, Ga. Calibration and verification...
Seismic studies at the Mt. Hood Volcano, northern Cascade Range, Oregon
Susan Molly Green, Craig S. Weaver, Hariharaiyer Mahadeva Iyer
1979, Open-File Report 79-1691
A sixteen station telemetered seismic network was established in the Mt. Hood, Oregon area to monitor local seismicity and to study crustal and upper mantle structure. The network was in operation 13 months, and recorded 10 local earthquakes, 25 regional events, and 300 teleseisms. A series of construction blasts were...
Earthquake Hazards Reduction Program project summaries: fiscal year 1978
Marilyn P. MacCabe
1979, Open-File Report 79-387
The Earthquake Hazard Reduction Program of the U.S. Geological Survey expanded threefold during fiscal year 1978. The program funded nearly 300 projects in the areas of earthquake hazards, earthquake prediction, induced seismicity, and global seismology. Brief summaries of each project are presented in this report, along with highlights of the...
Multiyear low flow in southeastern Kansas
William J. Carswell Jr.
1979, Open-File Report 79-1288
Many existing water supplies in southeastern Kansas are proving inadequate to meet current and expanded future needs. One of the methods in which the use of highly variable streamflow in the area can be evaluated is with the aid of multiyear low-flow frequency information. Data from 19 stream-gaging stations in...
A one-dimensional, steady-state, dissolved-oxygen model and waste-load assimilation study for Wildcat Creek, Howard County, Indiana
Charles G. Crawford, William G. Wilber, James G. Peters
1979, Open-File Report 79-1252
The Indiana State Board of Health is developing a water-quality management plan that includes establishing limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in Wildcat Creek was used to predict alternatives for future waste loadings that would be compatible with Indiana stream water-quality standards...
