Ground-water resources investigation in the Amran Valley, Yeman Arab Republic
G. Chase Tibbitts, James Aubel
1980, Open-File Report 80-774
A program of hydrologic studies and exploratory drilling was conducted intermittently between 1974 and 1978 to evaluate the water-bearing properties of the unconsolidated alluvial sediments and associated rocks in the semi-arid Amran Valley basin, an 800-square-kilometer area in north-central Yemen Arab Republic. Inventory data from 395 wells were compiled, observation...
Floods of January and February 1980 in California
Kenneth L. Wahl, John R. Crippen, J. M. Knott
1980, Open-File Report 80-1005
During January and February 1980, storms caused substantial rises in streamflow throughout much of California. In mid-January flooding occurred in the foothills of the Sierra Nevada and in the central coast area. In late January and mid-February, high floodflows in streams in coastal southern California caused much damage and several...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: February 1980
John B. Townshend, J.E. Papp, E.A. Sauter, S.P. Tilton
1980, Open-File Report 80-300-B
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Quantitative analysis versus semiquantitative optical emission spectrographic analysis of chromium, nickel, zinc, vanadium, and molybdenum in organic-rich Paleozoic marine strata, Western United States
George A. Desborough, F. G. Poole, Edwin K. Maughan, H.L. Groves, Gregory N. Green
1980, Open-File Report 80-1271
Comparison of analytical results between the quantitative method and the semiquantitative six-step optical-emission spectrographic method commonly shows significantly lower values for the semiquantitative method. The lower values are most obvious for splits from the same samples of fine-grained organic-rich rocks where the concentrations of the metals chromium, nickel, zinc, vanadium,...
Hydrology of Jumper Creek Canal basin, Sumter County, Florida
Warren Anderson
1980, Open-File Report 80-208
In 1960, floods caused extensive damage to agribusiness in Jumper Creek Canal basin. In 1962, a plan was developed for a proposed project to reduce the threat of floods. In 1976, a study of the hydrology of the basin was proposed to help evaluate this plan and to serve as...
