Geologic environment of the Van Norman Reservoirs area
R. F. Yerkes, M. G. Bonilla, T. L. Youd, J.D. Sims
1974, Circular 691-A
The upper and lower Van Norman dams, in northwesternmost San Fernando Valley about 20 mi (32 km) northwest of downtown Los Angeles, were severely damaged during the 1971 San Fernando earthquake. An investigation of the geologic-seismologic setting of the Van Norman area indicates that an earthquake of at least M...
Summary of hydrologic conditions and effects of Walt Disney World development in the Reedy Creek Improvement District, 1966-73
Arthur L. Putnam
1974, Open-File Report 74-339
The Reedy Creek Improvement District (hereinafter called the RCID) is an area of about 43 square miles (111. square kilometres) in southwest Orange and northwest Osceola Counties. Before development of Walt Disney World began (mid-1967), all of this tract of land was scrubby flatlands and swamp. Walt Disney World facilities...
Summary appraisals of the Nation's ground-water resources; Texas Gulf region
E. T. Baker Jr., James Ray Wall
1974, Open-File Report 74-331
Ground water in the Texas-Gulf Region is a large and important resource that can provide a more significant percentage of the total water supply of the region. Total water requirements within the region are projected to rise sharply from 14 million acre-feet (17 cubic kilometres) in 1970 to nearly 26...
Water resources of the Blue Earth River watershed, south-central Minnesota
H.W. Anderson, D.F. Farrell, W.L. Broussard
1974, Hydrologic Atlas 525
The Blue Earth River Watershed in Minnesota includes 3,106 square miles of land surface, which varies from fairly flat to gently rolling. The drainage extends south to include an additional 450 square miles in Iowa. The western, southern, and eastern boundaries are end moraines formed by Pleistocene glaciers. Major streams...
Water resources of the Cannon River watershed, southeastern Minnesota
H. W. Anderson Jr., D.F. Farrell, W.L. Broussard, P.E. Felsheim
1974, Hydrologic Atlas 522
The 1,462 square miles of land surface in the Cannon River watershed varies considerably from areas of low hills and plains to areas dominated by streams deeply incised into bedrock. Much of the south-central part of the area consists of a till plain that ranges in altitude from 1,100 to...
Preliminary report on the geology of the continental borderland of Southern California
J. G. Vedder, L. A. Beyer, A. Junger, G. W. Moore, A. E. Roberts, J. C. Taylor, H. C. Wagner
1974, Miscellaneous Field Studies Map 624
Appraisal of the mineral resource potential and assessment of environmental problems of any specific area require an understanding of the regional geology. The geology of t he coastal zone and offshore islands from Point Conception to the Mexican boundary serves as a frame of reference from which rock units and...
An assessment of areal and temporal variations in streamflow quality using selected data from the National Stream Quality Accounting Network
Timothy Doak Steele, Edward J. Gilroy, Richard O. Hawkinson
1974, Open-File Report 74-217
Streamflow chemical-quality data and stream-temperature data at 88 stations throughout the United States and Puerto Rico were analyzed to develop and to evaluate methodologies for the general assessment of the variation of the Nation's streamflow-quality conditions in space and over time. The spatial variation is described by the use of...
Geothermal investigations in Idaho, Part 2, An evaluation of thermal water in the Bruneau-Grand View area, southwest Idaho, with a section on a reconnaissance audio-magnetotelluric survey
H.W. Young, R.L. Whitehead, Donald B. Hoover, C. L. Tippens
1974, Open-File Report 74-221
The Bruneau-Grand View area occupies about 1,100 square miles in southwest Idaho and is on the southern flank of the large depression (possibly a graben) in which lies the western Snake River Plain. The igneous and sedimentary rocks in the area range in age from Late Cretaceous to Holocene. They...
Economic geology of the Isla de Mona Quadrangle, Puerto Rico
Reginald Peter Briggs
1974, Open-File Report 74-226
Limiting this tableland In the northern part of Isla de Mona are sheer sea cliffs chiefly exposing the Isla de Mona Dolomite. Around the southern part of the island are Irregular cliffs and steep slopes that chiefly expose the Lirio Limestone. The structure of Isla de Mona consists of two...
Water from the Coastal Plain aquifers in the Washington, D.C., metropolitan area
S.S. Papadopulos, R.R. Bennett, F. K. Mack, P.C. Trescott
1974, Circular 697
A brief study of the Atlantic Coastal Plain aquifers in the vicinity of the Washington, D.C., metropolitan area was made, using available data, to estimate the water-supply potential of these aquifers and to determine the possibility of developing an emergency water supply during droughts. Assuming that the data available are...
Mathematical model of San Juan Valley ground-water basin, San Benito County, California
Robert E. Faye
1974, Water-Resources Investigations Report 73-58
A mathematical model study of the San Juan Valley ground-water basin in San Benito County, Calif., has quantitatively described the ground-water hydrology of the basin under past, present, and future conditions of development. An analysis of conditions in the basin prior to large-scale ground-water development indicates that net recharge equaled...
Flashing flow in hot water geothermal wells
Manuel Nathenson
1974, Journal of Research of the U.S. Geological Survey (2) 743-751
The production characteristics of hot-water geothermal wells which flash to steam-water mixtures in the cased part of the hole were-analyzed. The flashing flow is assumed to be isenthalpic and, for purposes of calculating pressure drop, a finely dispersed mixture of equal average velocity. Water flow in the aquifer is treated...
