E.G. Lappala, P.F. Hemphill, R.E. Booker
1978, Open-File Report 78-461
Surface-water supplies are diminishing in the Hitchcock-Red Willow and Frenchman Valley Irrigation Districts in southwest Nebraska. Stream depletions due to ground-water withdrawals upstream from Enders Reservoir (northwest of the study area) have resulted in a shortage of about 8,700 acre-feet per year. The availability of ground water to supply part...

Impact of coastal processes on resource development with an example from Icy Bay, Alaska
Bruce F. Molnia
1978, Open-File Report 79-1693
The coastline of Alaska is dynamic and continually readjusting to changes in the many processes that operate in the coastal zone. Because of this dynamic nature, special consideration must be made in planning for development, and. caution must be exercised in site selection for facilities to be emplaced in the...

In April and Flay 1975, a U.S. Geological Survey marine geology field party under the leadership of Bruce F. Molnia and Paul R. Carlson collected geophysical data from the N.O.A.A. ship Surveyor. The cruise, which consisted of 3 legs, studied the area between Cross Sound and Seward (Figure 1). Maps...
FRISK: computer program for seismic risk analysis using faults as earthquake sources
Robin K. McGuire
1978, Open-File Report 78-1007
This computer program makes probabilistic seismic hazard calculations at sites affected by earthquakes occurring on faults which are defined by the user as a series of line segments. The length of rupture of the fault as a function of earthquake magnitude is accounted for, and ground motion estimates at the...
Water resources of the Cordova area, Alaska

An instrument system for long-term sediment transport studies on the continental shelf
Bradford Butman, David W. Folger
1978, Open-File Report 78-1019
A bottom-mounted instrument system has been designed and built to monitor processes of bottom-sediment movement on the Continental Shelf. The system measures bottom current speed and direction, pressure, temperature, and light transmission, and photographs the bottom. The instrument operates in a burst sample mode. The system can be deployed for...
Pennsylvanian (Upper Carboniferous) system of Wyoming
Edwin K. Maughan
1978, Open-File Report 78-377
Pennsylvanian rocks in Wyoming comprise two stratigraphic sequences bounded by regional unconformities. Red mudstone and limestone characterize the strata in the lower sequence, and sandstone and dolomite characterize the strata in the upper sequence. Initial deposits of the lower sequence are-red mudstone probably of no older age than about middle...
Potential hazards from future eruptions in the vicinity of Mount Shasta Volcano, northern California
C. Dan Miller
1978, Open-File Report 78-827
Mount Shasta has erupted, on the average, at least once per 800 years during the last 10,000 years, and about once per 600 years during the last 4,500 years. The last known eruption occurred about 200 radiocarbon years ago. Eruptions during the last 10,000 years produced lava flows and domes...
A summary of niobium and rare earth localities from Ha'il and other areas in western Saudi Arabia: a preliminary study

The water supply for the city of Madison, Wisconsin, and for surrounding municipalities is obtained from the ground-water reservoir that underlies the area. This ground-water reservoir is composed of an upper aquifer and an underlying sandstone aquifer. High-capacity water-supply wells pump from the sandstone aquifer. Pumping from the sandstone aquifer has...
