1977, Professional Paper 1008
The landslides in the Kearny and El Capitan Mountain quadrangles, Pinal and Gila Counties, Ariz., are tabular or lens like masses of megabreccia enclosed in Miocene basin deposits. The megabreccias within individual slide blocks are composed of pervasively brecciated Precambrian and younger formations that remain in normal stratigraphic sequence, indicating...
Application of a rainfall-runoff model in estimating flood peaks for selected small natural drainage basins in Texas
B.C. Massey, Elmer E. Schroeder
1977, Open-File Report 77-792
A parametric rainfall-runoff simulation model was used to synthesize long-term records of annual peak discharges for small natural drainage basins in Texas. Optimum model-parameter values were determined for each of the 40 basins studied by using short-term rainfall, evaporation, and discharge data. The calibrated model was used in conjunction with...

Effects of the catastrophic flood of December 1966, north rim area, eastern Grand Canyon, Arizona
Maurice E. Cooley, B. N. Aldridge, Robert C. Euler
1977, Professional Paper 980
Precipitation from the unusual storm of December 1966 was concentrated on highlands in northern Arizona, southwestern Utah , southern Nevada, and south-central California and caused widely scattered major floods in the four States. In Arizona the largest amount of precipitation was in the north rim area of eastern Grand Canyon,...
SIPB: a seismic refraction inverse modeling program for batch computer systems

1977, Open-File Report 77-366
SIPB is an interactive Fortran computer program that was developed for use with a timeshare computer system with program control information submitted from a remote terminal, and output data displayed on the terminal or printed on a line printer. The program is an upgraded version of FSIPI (Scott, Tibbetts, and...
Paleomagnetic investigation of late Quaternary sediments of south San Francisco Bay, California
John W. Hillhouse
1977, Open-File Report 77-457
Paleomagnetic inclinations of the Late Quaternary sediments of South San Francisco Bay were determined from bore hole samples collected near Dumbarton Bridge. The sediments consist of estuarine muds and nonmarine sand deposits, floored by bedrock of the Mesozoic Franciscan Formation. - Beneath Dumbarton Bridge the entire sedimentary fill is normally...

A brief investigation of the surface-water hydrology of Yemen Arab Republic
Henry Chiles Riggs
1977, Open-File Report 77-150
Yemen, near the southwest tip of the Arabian Peninsula, is a mountainous country bordered by a desert on the east and a coastal plain on the west. Rainfall is low and seasonal; consequently, most streams (wadis) are ephemeral. The natural flow regimens of many of the smaller wadis are modified...
Channel erosion surveys along the TAPS route, Alaska, 1977
Robert M. Loeffler, Joseph M. Childers
1977, Open-File Report 78-611
Channel surveys were made along the trans-Alaska pipeline system (TAPS) route during 1977 at the same 28 sites that were studied in 1976. In addition, a new site at pipeline mile 22 near Deadhorse (alignment No 134) along the Sagavanirktok River was put under surveillance. Except for changes wrought by...

Geology and ground-water in western Santa Cruz County, California, with particular emphasis on the Santa Margarita Sandstone
J. P. Akers, L.E. Jackson
1977, Water-Resources Investigations Report 77-15
The water-bearing potential of the geologic formations in the western part of Santa Cruz County, Calif., is evaluated. Most of the sedimentary formations in this area are fine-grained rocks of Tertiary age that have been folded and faulted. These rocks, in general, yield supplies of water sufficient only for individual...

1977, Water-Resources Investigations Report 77-63
A one-dimensional deterministic flow model based on the continuity equation had been developed to provide estimates of daily flow past a number of points on the Chowan River estuary of northeast North Carolina. The digital model, programmed in Fortran IV, computes daily average discharge for nine sites; four of these...

Donald Robert Rima, Mary S. Moran, E. Jean Woods
1977, Water-Resources Investigations Report 77-86
Ground water occurs in the Murfreesboro area in solution openings in the otherwise dense paleozoic limestones that underlie most of central Tennessee. Test drilling based on conceptual models of ground-water occurrence in carbonate-rock aquifers indicate that multimillion-gallon-per-day supplies could be developed from strategically located production wells in the Shiloh and...

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...
