Preliminary Catalog of Earthquakes in Northern Imperial Valley, California, January 1, 1977--March 31, 1977

Description: Seismic monitoring of the northern section of the Imperial Valley region in Southern California has been underway since 1973, in order to study in detail the relationship between geothermal areas and earthquakes. A description of the 22-station network and a list of preliminary data on earthquakes recorded by the network from January 1977 through March 1977 are presented.

Advanced subsystems development. Second semi-annual progress report, April 1--October 1, 1978

Description: The concept design for a small (less than 10 MWe) solar thermal electric generating plant was completed using projected 1985 technology. The systems requirements were defined and specified. The components, including an engineering prototype for one 15 kWe module of the generating plant, were conceptually designed. Significant features of the small solar thermal power plant were identified as the following: (1) 15-kWe Stirling-cycle engine/alternator with constant power output; (2) 10-meter poin… more

Preliminary Study of the Uranium Favorability of Mesozoic Intrusive and Tertiary Volcanic and Sedimentary Rocks of the Central Mojave Desert, Kern and San Bernardino Counties, California

Description: From purpose and scope: The purpose of this project was to determine the uranium favorability of Mesozoic intrusive rocks and Tertiary volcanic and sedimentary rocks in the central Mojave Desert. The project was conducted by Bendix Field Engineering Corporation (BFEC) under the auspices of the Grand Junction Office of the U.S. Energy Research and Development Administration (ERDA). The scope of the project included determination of the uranium content of different rock types, determination of th… more

Preliminary Study of the Uranium Favorability of Granitic and Contact-Metamorphic Rocks of the Owens Valley Area, Inyo and Mono Counties California, and Esmeralda and Mineral Counties, Nevada

Description: From summary: Granitic and contact-metamorphic rocks of the Owens Valley area were sampled to determine their favorability for uranium. Uranium deposits associated with these rocks were examined to determine the mode of occurrence.

Ground-Water Storage in the Johnson Valley Area, San Bernardino County, California

Description: Abstract: The Mojave Water Agency includes several desert basins where ground water in storage is many times as great as the average annual recharge. The Johnson Valley area was evaluated to find (1) the quantity of ground water in storage, (2) the chemical quality of the ground water, and (3) the potential for storage of recharge water in the unsaturated zone. Johnson Valley contains about 250,000 acre-feet of water in storage, of which about half can be considered recoverable. About 250,000 a… more

Evaluation of Thermograph Data for California Streams

Description: This report presents "statistical analysis of water-temperature data from California streams" and concludes that "long-term operation of thermographs does not prove a more useful record than either short-term operation of such instruments or periodic measurements." It contains tables and illustrations.

Marysville Lake Hydrothermal Study: Report 2

Description: Partial abstract: "This study was conducted to determine the effect that the proposed Marysville Lake pump-storage hydropower (2250-mw power plant) project would have on downstream water temperatures. A one-dimensional numerical model was used for simulation and prediction of temperatures within and downstream of Marysville Lake. Two physical hydraulic models were used for study and description of the hydrodynamic response of the project. Information from the physical models was necessary to de… more
