Distribution of nitrate and related nitrogen species in the unsaturated zone, Redlands and vicinity, San Bernardino County, California
John M. Klein, Wesley L. Bradford
1979, Water-Resources Investigations Report 79-60
Nitrogen in the unsaturated soil zone in the vicinity of Redlands in San Bernardino County, Calif., has been suspected as the source of nitrate in water from wells. Plans have been made to recharge the aquifer with imported surface water. If this occurs, the rising water table will intercept soluble...
Interim data report on the geohydrology of the proposed waste isolation pilot plant site, southeast New Mexico
Jerry W. Mercer, R.B. Orr
1979, Water-Resources Investigations Report 79-98
Data collected at the proposed Waste Isolation Pilot Plant site in southeast New Mexico through September 1977 help define hydrologic conditions at the contact between the Permian Rustler and Salado Formations, and Culebra and Magenta Dolomite Members of the Rustler Formation. Preliminary calculations of transmissivity along the Rustler-Salado contact range...
Application of transient-flow model to the Sacramento River at Sacramento, California
R.N. Oltmann
1979, Water-Resources Investigations Report 78-119
The transient-flow simulation model was applied to the Sacramento River at Sacramento, Calif. An alternative is needed to the empirical stage-fall-discharge computational method, which provides only daily mean discharges and requires frequent measurement over a 25- to 26-hour period of the tide-affected flow. Measurement of tide-affected flow involves use of...
1978 annual index of current earthquake literature
M. L. Prepared by Gunn, L. Addis, W.H.K. Lee
1979, Open-File Report 79-396
In the past several years, earthquake research has been greatly accelerated in China, Japan, USSR, and the United States. Presently, about 2,500 earthquake-related publications (including meeting abstracts) are produced yearly. In order to keep up with this current literature, a computer based bibliographic system was implemented as part of a...
Seismic refraction profile, Kingdom of Saudi Arabia: field operations, instrumentation, and initial results
H. Richard Blank, J. H. Healy, John Roller, Ralph Lamson, Fred Fisher, Robert McClearn, Steve Allen
1979, Open-File Report 79-1568
In February 1978 a seismic deep-refraction profile was recorded by the USGS along a 1000-km line across the Arabian Shield in western Saudi Arabia. The line begins in Paleozoic and Mesozoic cover rocks near Riyadh on the Arabian Platform, leads southwesterly across three major Precambrian tectonic provinces, traverses Cenozoic rocks...
