An investigation of basin effects on flood discharges in North Dakota
Orlo A. Crosby
1974, Open-File Report 74-346
An investigation of the relationship of peak discharge to causative storm variables and drainage-basin characteristics was made to provide guidelines for future analyses of frequency and magnitudes of floods from small drainage areas. The procedure used was (l) to estimate peak discharges on the ll study basins from multiple-regression models developed from the storm variables and...

Volcanic hazards on the Island of Hawaii
Donal Ray Mullineaux, Donald W. Peterson
1974, Open-File Report 74-239
Volcanic hazards on the Island of Hawaii have been determined to be chiefly products of eruptions: lava flows, falling fragments, gases, and particle-and-gas clouds. Falling fragments and particle-and-gas clouds can be substantial hazards to life, but they are relatively rare. Lava flows are the chief hazard to property; they are...

Flashing flow in hot water geothermal wells
Manuel Nathenson
1974, Journal of Research of the U.S. Geological Survey (2) 743-751
The production characteristics of hot-water geothermal wells which flash to steam-water mixtures in the cased part of the hole were-analyzed. The flashing flow is assumed to be isenthalpic and, for purposes of calculating pressure drop, a finely dispersed mixture of equal average velocity. Water flow in the aquifer is treated...
