From May 1975 through May 1976, water levels in the Floridan aquifer through most of north and central peninsular Florida declined 2 to 4 feet, on the basis of water-level measurements in 664 wells. These 664 were selected from a network of about 2,100 observation wells for which water-level measurements...

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...

The U.S. Geological Survey began a study to determine sediment yields for selected streams in Texas during the 1966 water year to provide information for areas in which sediment-yield data were meager or lacking. These data will aid in delineating problem areas and planning for water-resources development in the State....

The U.S. Geological Survey (USGS), in a cooperative agreement with the U.S. Department of Energy (DOE), is participating in the Eastern Gas Shales Project. The purpose of the DOE project is to increase the production of natural gas from eastern United States shales in petroliferous basins through improved exploration and extraction...

Ground-water discharge to Willow Creek, which drains a 204 mi2 watershed in northeast Nebraska was predicted for six combinations of conditions of climate and ground-water development. A digital model of the ground water/surface-water system was stressed with recharge and withdrawal functions determined from a linear reservoir model of the soil...

In the Highland-East Highlands area of southern California, concentrations of nitrate in water from many wells exceed the U.S. Environmental Protection Agency 's and the California Department of Health 's recommended limit for public water supplies. The nitrate standards for public water supplies in the study area are commonly met...

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...

Structural contours on the top of the Floridan aquifer in Duval County, Florida, show that the top of the aquifer ranges from less than 300 feet below sea level to more than 600 feet below sea level. Two inferred concealed faults occur in the aquifer; one trending northeast-southwest in the...

A map (scale 1:100,000) of the water table in Racine County in southeastern Wisconsin was prepared using water levels from more than 250 wells. The work was done as a cooperative project between the U.S. Geological Survey and the Southeastern Wisconsin Regional Planning Commission. The map shows the altitude of...

A map of the water table in Walworth County in southeastern Wisconsin was prepared using water levels from nearly 600 wells. The work was done as a cooperative project between the U.S. Geological Survey, the University of Wisconsin-Extension, Geological and Natural History Survey, and the Southeastern Wisconsin Regional Planning Commission....

Brevard County is an area of some 1,300 square miles located on the east coast of central Florida. The Titusville quadrangle, in northern Brevard, includes part of the Atlanta Coastal Ridge, an area of relatively high sand ridges that are generally above 30 feet in altitude (sheet 1). Approximately the...

Brevard County is an area of some 1,300 square miles located on the east coast of central Florida. The Titusville SW Quadrangle, in northern Brevard, includes part of the St. Johns River channel and valley with extensive areas of relatively low marshlands. Approximately one half of the quadrangle area lies...

Interpretation of all publicly available onshore gravity data provides a basis for outlining regional elements of the basement and overlying structure in the northern part of the Arctic National Wildlife Range. Major post-Carboniferous sedimentary basins whose centers lie offshore on the Beaufort Shelf extend onshore in the northern part of...

This paper provides a guide to measured sections of Upper Devonian (Famennian) and Mississippian (Kinderhookian, Osagean, and Meramecian) rocks visited on a three-day field trip between Provo, Utah, on the Wasatch Front and the Crawford Mountains in the Overthrust Belt along the Utah-Wyoming State line. The field trip, sponsored by...

Depth to water table, September 1976, and area inundated by the June 1975 flood in the Helena valley, Montana, are mapped on two sheets, Helena and East Helena 7.5-minute quadrangles, at scale 1:48,000. Depth to water table was mapped using water-level measurements from existing shallow observation wells and selected domestic...

Landsliding is a common problem in eastern Fairfax County, an area underlain by Potomac Group (Lower Cretaceous) Coastal Plain deposits of silt and clay interbedded and interfingered with sand and gravel. The slides commonly are present in clay and silt that, on the basis of laboratory tests, appear to be...

Mount St. Helens has been more active and more explosive during the last 4,500 years than any other volcano in the conterminous United States. Eruptions of that period repeatedly formed domes, large volumes of pumice, hot pyroclastic flows, and, during the last 2,500 years, lava flows. Some of this activity...

Studies of geotechnical properties of marine sediments have recently intensified as the search for natural resources has expanded on the continental shelf. The U. S. Geological Survey has begun a detailed evaluation of geologic environmental conditions in continental shelf regions in order to facilitate safe development of continental shelf resources....

The Northwest 58th Street solid-waste disposal facility, 3 miles west of a major Dade County municipal water-supply well field, overlays the Biscayne aquifer, a permeable, solution-riddled limestone which transmits leachates eastward at a calculated rate of 2.9 feet per day. A discrete, identifiable leachate plume has been recognized under and...
