Significance of ground-water chemistry in performance of North Sahara Tube wells in Algeria and Tunisia
Frank Eldridge Clarke, Blair F. Jones
1972, Water Supply Paper 1757-M
Nine ground-water samples from the principal shallow and deep North Sahara aquifers of Algeria and Tunisia were examined to determine the relation of their chemical composition to corrosion and mineral encrustation thought to be contributing to observed decline in well capacities within a UNESCO/UNDP Special Fund Project area. Although the...

Quality of the ground water in basalt of the Columbia River group, Washington, Oregon, and Idaho
Reuben Clair Newcomb
1972, Water Supply Paper 1999-N
The ground water within the 50,000-square-mile area of the layered basalt of the Columbia River Group is a generally uniform bicarbonate water having calcium and sodium in nearly equal amounts as the principal cations. water contains a relatively large amount of silica. The 525 chemical analyses indicate that the prevalent...

Urban hydrology: A selected bibliography with abstracts
George L. Knapp, J.P. Glasby
1972, Water-Resources Investigations Report 72-3
This bibliography of 650 selected references on urban hydrology is intended as a source document for scientific and water-management needs. It was stimulated by increasing interest in the problems of runoff and water quality caused by increasing urbanization. The bibliography brings together abstracts with citations that pertain to the rainfall-runoff...

Map showing landslides and areas of potential landsliding in the Salina quadrangle, Utah
Paul L. Williams
1972, IMAP 591-L
The term “landslide” is broadly defined as any “downward and outward movement of slope-forming materials composed of natural rock, soils, artificial fills, or combinations of these materials. The moving mass may proceed by any one of three principal types of movement: falling, sliding, or flossing, or by their combinations” (Varnes,...

Ground-water in the Teresina-Campo Maior area, Piaui, Brazil
Harry G. Rodis, Edison F. Suszczynski
1972, Water Supply Paper 1663-G
The Teresina-Campo Maior area lies in a presently developing farming and grazing region near the margin of drought-prone northeast Brazil where irrigated farming offers the best potential for economic development. The area comprises 9,700 square kilometers largely of catinga-covered tabular uplands which are drained by the perennial Rio Parnatba. The...
Preliminary photointerpretation map of landslide and other surficial deposits of the Mount Hamilton quadrangle and parts of the Mount Boardman and San Jose quadrangles, Alameda and Santa Clara Counties, California
Tor H. Nilsen
1972, Miscellaneous Field Studies Map 339
The nine San Francisco Bay region counties lie within a geologically active, young, and dynamic part of the central and northern Coast Ranges of California. Significant movements of the earth's crust are occurring here at the present time, posing numerous problems to urbanization, including some of special concern. Geological processes...

Runoff characteristics of California streams
S. E. Rantz
1972, Water Supply Paper 2009-A
California streams exhibit a wide range of runoff characteristics that are related to the climatologic, topographic, and geologic characteristics of the basins they drain. The annual volume of runoff of a stream, expressed in inches, may be large or small, and daily discharge rates may be highly variable or relatively...
