Hydrologic- and salt-balance investigations utilizing digital models Lower San Luis Rey River area, San Diego County, California
Joe A. Moreland
1974, Water-Resources Investigations Report 74-24
The Joint Administration Committee of the Santa Margarita and San Luis Rey Watershed Planning Agencies was designated as the agency to conduct studies leading to the development of a comprehensive water-quality management plan for the two watersheds. Hydrologic and salt balances for the Pauma, Pala, Bonsall, and Mission ground-water basins...
Mineral resources of proposed additions to the Salmon-Trinity Alps Primitive Area, California
Preston E. Hotz, Robert C. Greene, Terry J. Close, Robert K. Evans
1974, Open-File Report 74-71
A mineral survey of four areas totalling 80 square miles, not included during the 1968-70 examination of the proposed Salmon-Trinity Alps Wilderness, was made by the U.S. Geological Survey and U.S. Bureau of Mines in 1973. Geological Survey personnel mapped the geology and collected stream-sediment and rock samples for spectrographic...
A special planning technique for stream-aquifer systems
C.T. Jenkins, O. James Taylor
1974, Open-File Report 74-242
The potential effects of water-management plans on stream-aquifer systems in several countries have been simulated using electric-analog or digital-computer models. Many of the electric-analog models require large amounts of hardware preparation for each problem to be solved and some become so bulky that they present serious space and access problems....
Water-quality and geohydrologic data at two sanitary landfill sites near Anchorage, Alaska
Chester Zenone, D.E. Donaldson
1974, Open-File Report 74-1131
Water-quality and geohydrologic data were collected at two sanitary landfill (solid-waste disposal) sites near Anchorage, Alaska. The study was undertaken by the U.S. Geological Survey in cooperation with the Greater Anchorage Area Borough and the U.S. Air Force. The purpose of the study was to evaluate the environmental effects of...
Water availability in central Wisconsin — An area of near-surface crystalline rock
Edwin Allen Bell, Marvin G. Sherrill
1974, Water Supply Paper 2022
Available ground water in much of central Wisconsin is limited to discharge through wells of low yield. Aquifers that yield small amounts of water to wells include fractured crystalline rock at or near surface in the eastern part of the area, sandstone overlying crystalline rock in the southern and western...
Hydrologic unit map:1974, State of Utah
Water Resources Division, U.S. Geological Survey
1974, Hydrologic Unit 44
This map and accompanying table show Hydrologic Units that are basically hydrographic in nature. The Cataloging Units shown will supplant the Cataloging Units previously used by the U.S. Geological Survey in its Catalog of Information on Water Data (1966-72). The previous U.S. Geological Survey Catalog-Indexing System was by map number...
