Evaluation of major dike-impounded ground-water reservoirs, Island of Oahu, with a section on flow hydraulics in dike tunnels in Hawaii
Kiyoshi J. Takasaki, John F. Mink
1981, Open-File Report 81-1119
Ground-water reservoirs impounded by volcanic dikes receive a substantial part of the total recharge to ground water on the island of Oahu because they generally underlie the rainiest areas. They accumulate the infiltration from rainfall, store it temporarily, and steadily leak it to abutting basal reservoirs or to streams cutting...
Single-channel seismic-reflection profiles and sidescan-sonar records collected on Georges Bank
David C. Twichell
1981, Open-File Report 81-438
Subbottom seismic-reflection, echo-sounding, and sidescan-sonar records were collected by the U.S. Geological Survey during two cruises over Georges Bank aboard the R/V OCEANUS (cruise 056, March 6-15, 1979 and cruise 067, August 6-13, 1979) (fig. 1). The data collected during these two cruises contributed to a study of bed-form types...

INTRODUCTION The San Francisco Peaks area includes about 2,300 mi2, of which about 500 mi2 is in the Navajo Indian Reservation, in north-central Arizona. Ground-water development has been slight except for the public-supply wells for Flagstaff and domestic wells in Fort Valley, Pitman Valley, and the area west of Elden Mountain....
Preliminary report on geophysics ground follow-up of the 1977 airborne survey in the Wadi Bidah District, Kingdom of Saudi Arabia
V. J. Flanigan, J. C. Wynn, R. G. Worl, C. W. Smith
1981, Open-File Report 82-202
Reconnaissance geologic and geochemical sampling was made during the 1978 field season at most of the 50 or so electromagnetic anomalies detected in the 1977 airborne electromagnetic (AEM) survey of the Wadi Bidah district. These Phase 1 studies also included reconnaissance geophysical traverses of nine of the AEM conductors. In...
