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...
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...
Map Showing Areas Containing Swelling Clay in the Morrison Quadrangle, Jefferson County, Colorado
Glenn R. Scott
1972, IMAP 790-C
Formations that contain clays having swelling pressures higher than 2,500 pounds per square foot (as measured by the Potential Volume Change meter) are listed in order of decreasing swelling pressure: Denver Formation, Pierre Shale, Laramie Formation, Green Mountain Conglomerate, Fox Hills Sandstone, and Arapahoe Formation. Some landslides derived from these...
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

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...
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 motion values for use in the seismic design of the Trans-Alaska Pipeline system
Robert A. Page, D.M. Boore, W. B. Joyner, H.W. Coulter
1972, Circular 672
The proposed trans-Alaska oil pipeline, which would traverse the state north to south from Prudhoe Bay on the Arctic coast to Valdez on Prince William Sound, will be subject to serious earthquake hazards over much of its length. To be acceptable from an environmental standpoint, the pipeline system is to...
