Test drilling in basalts, Lalamilo area, South Kohala District, Hawaii
Warren E. Teasdale
1980, Open-File Report 80-1299
Test drilling has determined that a downhole-percussion airhammer can be used effectively to drill basalts in Hawaii. When used in conjunction with a foam-type drilling fluid, the hammer-bit penetration rate was rapid. Continuous drill cuttings from the materials penetrated were obtained throughout the borehole except from extremely fractured or weathered...
The heliothermic lake: a direct method of collecting and storing solar energy
Douglas W. Kirkland, J. Platt Bradbury, Walter E. Dean
1980, Open-File Report 80-807
Heliothermic lakes contain a sun-heated layer of warm, saline water beneath a surface layer of cooler, less saline water. The two layers are separated by a chemocline, a stratum in which salinity increases progressively with depth. The chemocline, the position of which varies from lake to lake, functions as a...
Floods in the Raccoon River basin, Iowa
Albert J. Heinitz
1980, Open-File Report 80-162
Evaluation of flood hazards, and the planning, design, and operation of various facilities on flood plains requires information on floods. This report provides information on flood stages and discharges, flood magnitude and frequency, bench mark data, and flood profiles for the Raccoon River and some of its tributaries. It covers...
In-situ measurements of seismic velocity at 27 locations in the Los Angeles, California region
James F. Gibbs, Thomas E. Fumal, Edward F. Roth
1980, Open-File Report 80-378
Studies conducted in the San Francisco Bay Region (Gibbs, Fumal and Borcherdt, 1980) have shown that average shear-wave velocity can be readily tied to quantitative estimates of ground motion such as ground amplification and earthquake intensity. Furthermore, when certain physical properties of the geologic materials such as texture, hardness and...
