1981, Open-File Report 81-211
A May 1980 potentiometric surface map of the Suwannee River Water Management District area, Florida, depicts water levels in wells tapping the Floridan aquifer. Compared to the May 1976 potentiometric map of the area, there are no significant differences in the general appearance of the contours. Water levels, however, are...
Sediment analyses for selected sites on the South Platte River in Colorado and Nebraska, and the North Platte and Platte rivers in Nebraska; suspended sediment, bedload, and bed material
J. E. Kircher
1981, Open-File Report 81-207
Sediment samples were collected on the South Platte, North Platte, and Platte Rivers in Colorado and Nebraska during the 1979 and 1980 runoff seasons. Suspended-sediment concentrations ranged from 62 to 3,705 milligrams per liter and the maximum load was 45,547 metric tons per day. The percentage of suspended sediment samller...
Potentiometric surface of the Floridan aquifer in the Northwest Florida Water Management District, May 1980

1981, Open-File Report 81-205
A May 1980 potentiometric surface map of the Northwest Florida Water Management District depicts water levels in wells tapping the Floridan aquifer prior to summer pumpage. Compared to earlier potentiometric maps of the area, there are no significant differences in the 1980 map that are the result of hydrologic conditions....
Water-resources investigations of the U.S. Geological Survey in Wyoming, fiscal year 1980
S. L. Green
1981, Open-File Report 81-201
This report contains lists and location maps of streamflow and reservoir stations, ground-water stations, water-quality stations, sediment stations, and peak-flow partial-record stations that are currently being operated in Wyoming. Water-resources appraisal projects are also described, including many that are related to development of energy resources. The general locations of the...

Seismic-reflection and sidescan-sonar data collected on the Potomac River, Maryland and Virginia, during May 1979
Harley J. Knebel
1981, Open-File Report 81-174
The U.S. Geological Survey collected 2,170 line kilometers of single-channel seismic-reflection profiles and sidescan sonar records on the Potomac River during R/V NEECHO cruise NE-3-79 in May 1979. The purposes of the survey were to define: (1) areas of sediment accumulation and erosion; (2) the thickness of Holocene sediments; (3)...

Status of Regional Gravity Project, Kingdom of Saudi Arabia, as of 1 January, 1979
M. E. Gettings
1981, Open-File Report 81-165
Regional gravity data have now been obtained for approximately 33 percent of the area of the Arabian Shield, associated harrat areas, and the Red Sea coastal plain. Virtually no surveys have been done on the Phanerozoic platform around the edges of the shield, and although regional gravity coverage is available...
