Graded layering in the Al Hadah pluton near At Ta'if, Kingdom of Saudi Arabia
Donald G. Hadley, William R. Greenwood
1977, Open-File Report 77-594
To assess urban storm-water-quality characteristics in the metropolitan area of Portland, Oreg., seven drainage basins were selected with varying drainage areas, basin slopes, impervious areas, land uses, and active construction areas. Automatic water-quality samplers, rain gages, and stream gages were installed in each basin. From September 1, 1975, to May...
Maximum floodflows in the conterminous United States
John R. Crippen, Conrad D. Bue
1977, Water Supply Paper 1887
Peak floodflows from thousands of observation sites within the conterminous United States were studied to provide a guide for estimating potential maximum floodflows. Data were selected from 883 sites with drainage areas of less than 10,000 square miles (25,900 square kilometers) and were grouped into regional sets. Outstanding floods for...
Calcic soils and calcretes in the southwestern United States
George Odell Bachman, Michael N. Machette
1977, Open-File Report 77-794
Secondary calcium carbonate of diverse origins, 'caliche' of many authors, is widespread in the southwestern United States. 'Caliche' includes various carbonates such as calcic soils and products of groundwater cementation. The term 'caliche' is generally avoided in this report in favor of such terms as calcrete, calcic soils, and pervasively...
Thermal loading of natural streams
Alan P. Jackman, Nobuhiro Yotsukura
1977, Professional Paper 991
The impact of thermal loading on the temperature regime of natural streams is investigated by mathematical models, which describe both transport (convection-diffusion) and decay (surface dissipation) of waste heat over 1-hour or shorter time intervals. The models are derived from the principle of conservation of thermal energy for application to...
Catalog of seismograph stations operated in support of the ERDA Nevada Operations Office, January 1964 thru June 1976
R. Navarro, Geraldine M. Wuollet, B.R. Bradley
1977, Open-File Report 77-404
The seismograph stations listed in this catalog were established over the period January 1964 through June 1976 in support of the Energy Research and Development Administration, Nevada (ERDA/NV) underground weapons testing program at the Nevada Test Site (NTS), central Nevada, and Amchitka, Alaska. For station listings before 1964 see Coast...
Analog-model analysis of regional three-dimensional flow in the ground-water reservoir of Long Island, New York
Rufus T. Getzen
1977, Professional Paper 982
A three-dimensional analog model of the ground-water system beneath Long Island, N.Y., provides a practical means for studying anisotropic flow on a regional scale. Constructional and operational techniques influence the simulation almost as much as model design does. Usefulness and accuracy of the model depend on (1) inherent and practical...
Low-flow characteristics of streams on the Olympic Peninsula, Washington
W.L. Haushild, D.E. LaFrance
1977, Open-File Report 77-812
Streams in lowland basins of the Olympic Peninsula, Washington, generally have their low flows in summer and peak flows in winter, whereas streams originating at higher elevations in the mountains have their low flows in late summer-early fall and they have both winter and spring peak flows. Data from long-term...
Data from geologic investigations in the Yemen Arab Republic during 1976
Maurice J. Grolier, J. A. Domenico, Mary Donato, G. Chase Tibbitts Jr., W.C. Overstreet, Mohammad Mukred Ibrahim
1977, Open-File Report 77-733
The results of semiquantitative spectrographic analyses for 31 elements in 126 specimens of rocks from the Yemen Arab Republic, collected mainly during February 1976 from the Precambrian area in the southeastern part of the country, provide background data for use in geochemical evaluation of areas potentially favorable for mineral deposits....
Hydrologic reconnaissance of the eastern North Slope, Alaska, 1975
Joseph M. Childers, C. E. Sloan, J.P. Meckel, J. W. Nauman
1977, Open-File Report 77-492
The part of the Arctic coast of Alaska between the Colville River and the Canadian boundary was visited in April, August, and November 1975. The study area is characterized by its cold climate and is largely uninhabited, but oil and gas discoveries have spurred development of parts of the area....
In-situ measurements of seismic velocities in the San Francisco Bay Region; part III
James F. Gibbs, Thomas E. Fumal, Roger D. Borcherdt, Edward F. Roth
1977, Open-File Report 77-850
Seismic wave velocities (compressional and shear) are important parameters for estimating the seismic response characteristics of various geologic units when subjected to strong earthquake ground shaking. Seismic velocities of various units often show a strong correlation with the amounts of damage following large earthquakes and have been used as a...
Hydrologic Data for Urban Studies in the Fort Worth, Texas Metropolitan Area, 1975
R.M. Slade Jr., J.M. Taylor
1977, Open-File Report 77-266
This report contains rainfall and runoff data collected during the 1975 water year for Sycamore Creek, Sycamore Creek tributary , Dry Branch, and Little Fossil Creek study areas in Fort Worth, Texas. The information will be useful in determining the extent to which progressive urbanization will affect the yield and...
Quality of rivers of the United States, 1974 water year: based on the National Stream Quality Accounting Network (NASQAN)
Richard O. Hawkinson, John F. Ficke, L.G. Saindon
1977, Open-File Report 77-151
The National Stream Quality Accounting Network (NASQAN) was established by the U.S Geological Survey to determine and compare the quality at key locations on the Nation 's major rivers. There are 345 stations in the network--data from the first 101 of these (those operating during the 1974 water year) are...
Report on preliminary data for Madison Limestone test well no.1, NE1/4 SE1/4 section 15, T. 57 N., R. 65 W., Crook County, Wyoming
Richard K. Blankennagel, W. R. Miller, D.L. Brown, E. M. Cushing
1977, Open-File Report 77-164
This report provides the preliminary data for the Madison Limestone test well no. 1 in Crook County, Wyoming, including test-well history, geology of the test well, hydrologic testing, and geochemistry. The test well was drilled to a depth of 4,341 feet to determine the water-resource potential of the Madison Limestone...
A description of the index of active Florida water data collection stations and a user's guide for station or site information retrieval using computer program Findex H578
M. L. Merritt
1977, Open-File Report 77-703
A computerized index of water-data collection activities and retrieval software to generate publication list of this information was developed for Florida. This system serves a vital need in the administration of the many and diverse water-data collection activities. Previously, needed data was very difficult to assemble for use in program...
