Geologic map of Late Cenozoic deposits, Santa Clara County, California
E. J. Helley, E. E. Brabb
1971, Open-File Report 71-150
This map is the first of several in the San Francisco Bay region showing the distribution and differentiation of the late Cenozoic alluvial, estuarine, and volcanic deposits. The sedimentary deposits of gravel, sand, silt, and clay were separated into geologic map units on the basis of their post-depositional soil development,...
Water-level changes 1964-71, northern High Plains of Colorado
Warren E. Hofstra, John M. Klein, Thomas J. Major
1971, Open-File Report 72-166
Ground-water withdrawals for irrigation increased from about 84,000 acre-feet to 430,000 acre-feet per year between 1960 and 1970 in the northern High Plains of Colorado, causing significant water-level declines in areas where high-capacity wells are concentrated. The number of wells increased from about 500 in 1960 to 2,560 in 1970....
Preliminary tectonic map of the Arabian Peninsula
Glen F. Brown
1971, Open-File Report 71-57
In 1963, in response to a request from the Ministry of Petroleum and Mineral Resources, the Saudi Arabian Government and the U. S. Geological Survey, U. S. Department of the Interior, with the approval of the U. S. Department of State, undertook a joint and cooperative effort to map and...
Thermal study of the Missouri River in North Dakota using infrared imagery
Orlo A. Crosby
1971, Open-File Report 71-81
Studies of infrared imagery obtained from aircraft at 305- to 1,524- meter altitudes indicate the feasibility of monitoring thermal changes attributable to the operation of thermal-electric plants and storage reservoirs, as well as natural phenomena such as tributary inflow and ground-water seeps, in large rivers. No identifiable sources of ground-water...
Summary of ground-water hydrological data in Michigan in 1970
G.C. Huffman, T. Thompson
1971, Open-File Report 72-173
The purpose of this report is to make available the records of groundwater levels in principal aquifers of the State through 1970 and to compile other related data, such as records of ground-water pumpage, data on municipal, public and industrial water-supply facilities, and the effects of precipitation on ground-water levels....
Generalized flood-frequency estimates for urban areas in Missouri
Ector Eugene Gann
1971, Open-File Report 71-116
A method is presented for estimating flood-frequency information for urban areas in Missouri. Flood-frequency relations are presented which provide an estimate of the flood-peak discharge for floods with recurrence intervals from 2.33 to 100 years for basins with various degrees of existing or projected urban development. Drainage area sizes for...
Geohydrologic sections, Cache Valley, Utah and Idaho
L. J. McGreevy, L.J. Bjorklund
1971, Open-File Report 71-193
This report was prepared as a part of a study of the ground-water resources of Cache Valley, Utah and Idaho. The study by the U.S. Geo- logical Survey was made during 1967-70 in cooperation with the Utah Department of Natural Resources, Division of Water Rights. The U.S. Bureau of Reclamation...
