Gravity map of the Nabesna Quadrangle, Alaska
David F. Barnes, Robert L. Morin
1975, Miscellaneous Field Studies Map 655-I
The gravity map of the Nabesna quadrangle indicates significant variations in the densities and thicknesses of the rock units that underlie the quadrangle. Most of this gravity relief is indirectly related to regional topographic relief or lithologic variations that are revealed in the rock outcrops. However, some significant features of...
Maps showing maximum earthquake intensity predicted in the southern San Francisco Bay region, California, for large earthquakes on the San Andreas and Hayward Faults
Roger D. Borcherdt, James F. Gibbs, Kenneth R. Lajoie
1975, Miscellaneous Field Studies Map 709
This map shows maximum earthquake intensity predicted at specific sites using the empirical relations derived from the reliable 1906 intensity data (figs. 3 and 4; see text). The numbers 4-0 correspond to letters A-E, respectively, of the San Francisco intensity scale. The predicted intensity value shown for each site is...
Preliminary map of landslide deposits, Denver 1° by 2° Quadrangle, Colorado
Roger B. Colton, Jeffrey A. Holligan, Larry W. Anderson
1975, Miscellaneous Field Studies Map 705
Areas inferred to be underlain by landslide deposits resulting from landsliding, avalanching, block gliding, debris sliding or flowing, earthflows, mudflows, rocksliding, rockfalls, rotational slides, slab or flake sliding, slumping, talus accumulation, and translational sliding. Rock glacier deposits, colluvium, and solifluction deposits are included in some areas. Some till is mapped...
Geological Survey research, 1975
Water Resources Division, U.S. Geological Survey
1975, Professional Paper 975
'Geological Survey Research 1975 ' is the 16th annual synopsis of the results of U.S. Geological Survey investigations. These studies are largely directed toward the development of knowledge that will assist the Nation to use and conserve the land and its physical resources wisely. They are wide ranging in scope...
Sediment transport, turbidity, channel configuration, and possible effects of impoundment of the Mad River, Humboldt County, California
William M. Brown III
1975, Water-Resources Investigations Report 75-26
Sediment-transport conditions were determined at two stations, Mad River near Arcata and Mad River near Kneeland. Using a release-flow model and an empirical equation, the suspended-sediment discharge at Kneeland was estimated to be about 60 percent of the suspended-sediment discharge at the Arcata station. The study of the proposed impoundment...
Evaluation of reservoir sites in North Carolina: Regional relations for estimating the reservoir capacity needed for a dependable water supply
F.E. Arteaga, E. F. Hubbard
1975, Water-Resources Investigations Report 74-46
Draft-storage-frequency relations, which show the storage required for a reservoir to furnish a specified withdrawal or draft are regionalized for four zones in the State, using the mean annual flow of the streams as an index. The differences between the zones primarily reflect differences in the variability of stream flow.To...
