Status of the National Water Data Exchange (NAWDEX) - September 1977
Melvin D. Edwards
1978, Open-File Report 78-154
Major progress in the implementation of the National Water Data Exchange (Nawdex) took place during Fiscal Year 1977--beginning October 1, 1976 and ending September 30, 1977. This report describes the status of the program at the end of this period. Program advancement is reported in the areas of administration, membership,...
Identification codes for organizations listed in computerized data systems of the U.S. Geological Survey
Melvin D. Edwards, Margery O. Drilleau
1978, Open-File Report 78-398
This report contains codes for the identification of public and private organizations listed in computerized data systems. These codes are used by the U.S. Geological Survey 's National Water Data Exchange (NAWDEX), National Water Data Storage and Retrieval System (WATSTORE), National Cartographic Information Center (NCIC), and Office of Water Data...
A table of photopeaks useful in nuclear geophysics
Allan B. Tanner, Frank E. Senftle
1978, Open-File Report 78-531
The table lists full-energy, single-escape, and double-escape photopeak energies corresponding to about 1800 x- and gamma rays derived from natural radioactivity, X-ray fluorescence, neutron reactions, and induced radioactivity. Photon lines have been selected on the basis of their importance in borehole logging by nuclear methods. The mode of production of...
Historic ground failures in Northern California triggered by earthquakes
T. Leslie Youd, Seena N. Hoose
1978, Professional Paper 993
A major source of earthquake-related damage and casualties in northern California has been ground failures generated by the seismic shaking, including landslides, lateral spreads, ground settlement, and surface cracks. The historical record shows that, except for offshore shocks, the geographic area affected and the quantity and general severity of ground...
Measured crustal deformation in Imperial Valley, California
Ben Elder Lofgren
1978, Open-File Report 78-910
Precise geodetic surveys since 1972 indicate that significant vertical deformation of the land surface continues in Imperial Valley, California. Measured vertical changes as great as 3.5 cm per year indicate that two types of tectonic movement are occurring: (1) a downward regional tilt of the valley surface from the Mexican...
Hydrologic data for urban studies in the Austin, Texas metropolitan area, 1976
Marion L. Maderak, J.D. Gordon, R.N. Mitchell
1978, Open-File Report 78-457
Hydrologic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. Studies are now in progress in Austin, Dallas and Dallas County, Fort Worth, Houston, and San Antonio.The Geological Survey, in cooperation with the Texas Department of Water Resources, began hydrologic studies in the Austin...
Program objectives for the National Water Data Exchange (NAWDEX) for fiscal year 1979
Melvin D. Edwards
1978, Open-File Report 78-975
This report describes the program objectives of the National Water Data Exchange (NAWDEX) for Fiscal Year 1979. These objectives include NAWDEX membership, program administration, management, and coordination, NAWDEX services, identification of sources of water data, indexing of water data, programs and systems documentation, recommended methods for the handling and exchange...
Notes on availability of multi-channel seismic processing programs
Robert Brune
1978, Open-File Report 78-421
During the past two years, a seismic processing system has been developed within Western Region offices of the U.S. Geological Survey (Pacific-Arctic Branch of Marine Geology). This brief report describes some of the programs within this system that may be of value to others. We process seismic reflection data taken...
Geologic map of the central far side of the Moon
D.E. Stuart-Alexander
1978, IMAP 1047
This map is one of a series of geologic maps that will cover the entire Moon at a scale of 1:5,000,000. The geology of the central far side is compiled largely from NASA Lunar Orbiter...
Application of digital profile modeling techniques to ground-water solute transport at Barstow, California
Stanley G. Robson
1978, Water Supply Paper 2050
This study investigated the use of a two-dimensional profile-oriented water-quality model for the simulation of head and water-quality changes through the saturated thickness of an aquifer. The profile model is able to simulate confined or unconfined aquifers with nonhomogeneous anisotropic hydraulic conductivity, nonhomogeneous specific storage and porosity, and nonuniform saturated...
Floods of September 1970 in Arizona, Utah, Colorado, and New Mexico
R.H. Roeske, Maurice E. Cooley, B. N. Aldridge
1978, Water Supply Paper 2052
During September 5-7, 1970, unusually large floods occurred in the mountains of central Arizona and in the Four Corners area of Arizona, Utah, Colorado, and New Mexico. Flooding also occurred in southern and northeastern Arizona. The record-high rainfall of September 5 occurred when a mass of moist tropical air from...
