Graphical method for estimating occurrence and duration of a critical low flow in the Sacramento River at Freeport, California
J.G. Harmon
1983, Water-Resources Investigations Report 82-4001
Sacramento County expects to begin operation of the Sacramento Regional Wastewater Treatment Plant in 1982. The California State Water Resources Control Board has ruled that the plant will not be allowed to release effluent into the Sacramento River when flow in the river is 4,000 cubic feet per second or...
Sediment transport in the Tanana River near Fairbanks, Alaska, 1982
P.E. Harrold, R.L. Burrows
1983, Water-Resources Investigations Report 83-4213
Suspended-sediment and bedload-transport rates for the Tanana River near Fairbanks can be related to water discharge, and annual sediment loads can be computed using these relations. For a site at Fairbanks the annual loads in 1982 were 26.1 million metric tons of suspended sediment and 227,000 metric tons of bedload....
Preliminary thermal-maturity map of the Cameo and Fairfield or equivalent coal zone in the Piceance Creek Basin, Colorado
Vito F. Nuccio, Ronald C. Johnson
1983, Miscellaneous Field Studies Map 1575
This map was prepared in cooperation with the U.S. Department of Energy's Western Gas Sands Project and was constructed to show the thermal maturity of the Upper Cretaceous Mesaverde Formation (or Group) in the Piceance Creek Basin. The ability of a source rock to generate oil and gas is directly...
Ground water in north Monterey County, California, 1980
M. J. Johnson
1983, Water-Resources Investigations Report 83-4023
Present ground-water demands exceed long-term recharge throughout much of North Monterey County in the shallow Quaternary deposits--principally the upper part of the Aromas Sand--and the overlying alluvium. Recharge occurs largely from local precipitation, although small quantities of potable ground water from outside areas also recharge these aquifers. Water levels in...
Comparative physiographic diagrams of Mount St. Helens, Washington, and Crater Lake, Oregon
Tau Rho Alpha, Jim M. Morley
1983, Miscellaneous Field Studies Map 1403
These physiographic diagrams provide a visual comparison of two Cascade Range volcanoes which have had their tops destroyed in different ways -- Mount St. Helens in 1980, Mount Mazama (whose site is now occupied by Crater Lake) about 6,800 years ago. Both volcanoes are viewed from the north from 30...
Subsidence from underground mining; environmental analysis and planning considerations
Fitzhugh T. Lee, John F. Abel
1983, Circular 876
Subsidence, a universal process that occurs in response to the voids created by extracting solids or liquids from beneath the Earth's surface, is controlled by many factors including mining methods, depth of extraction, thickness of deposit, and topography, as well as the in situ properties of the rock mass above...
A microcomputer-based data acquisition and control system for the direct shear, ring shear, triaxial shear, and consolidation tests
Philip S. Powers
1983, Open-File Report 83-491
This report is intended to provide internal documentation for the U.S. Geological Survey laboratory's automatic data acquisition system. The operating procedures for each type of test are designed to independently lead a first-time user through the various stages of using the computer to control the test. Continuing advances in computer...
Assessment of the interconnection between Tampa Bay and the Floridan aquifer, Florida
C. B. Hutchinson
1983, Water-Resources Investigations Report 82-54
Factors that control interflow between Tampa Bay and the Floridan aquifer are assessed, both qualitatively and quantitatively, with emphasis on the impact of harbor improvement. Hydrogeologic units underlying the 350-square-mile bay include the surficial-sand aquifer, upper sand and clay confining bed, and limestone of the Floridan aquifer. The surficial aquifer...
Recommended procedures and methodology of coal description
E.C. Chao, J.A. Minkin, C.L. Thompson
1983, Circular 894
This document is the result of a workshop on coal description held for the Branch of Coal Resources of the U.S. Geological Survey in March 1982. It has been prepared to aid and encourage the field-oriented coal scientist to participate directly in petrographic coal-description activities. The objectives and past and...
Streamflow losses and changes in ground-water levels along the Salt and Gila Rivers near Phoenix, Arizona — February 1978 to June 1980
L. J. Mann, P. B. Rohne
1983, Water-Resources Investigations Report 83-4043
From March 1978 to June 1980, high runoff from the Salt and Verde drainage basins combined with large carryover storage in a reservoir system led to the release of about 8.26 million acre-feet of water. About 2.89 million acre-feet of the water was diverted above Granite Reef Dam, and about...
Hydrologic conditions in the Wheatland Flats area, Platte County, Wyoming
M. A. Crist
1983, Water-Resources Investigations Report 83-4047
The area includes about 260 square miles in central Platte County that consists of Wheatland Flats and a border region. Wheatland Flats is an area of about 100 square miles that is bounded by Chugwater Creek on the east, the Laramie River on the north, and Sybille Creek on the...
Computer program and data listing for two-dimensional ground-water model for Laramie County, Wyoming
M. A. Crist
1983, Water-Resources Investigations Report 83-4137
This is a supplement to the report, ' Effect of pumpage on ground-water levels as modeled in Laramie County, Wyoming, ' published as U.S. Geological Survey Water-Resources Investigations Open-File Report 80-1104. The computer program and data used to model ground-water conditions in post-Cretaceous rocks in Laramie County are listed. (USGS)...
