Preliminary estimate of the amplification of possible earthquake ground motion at a site in Charleston County, South Carolina
Russell L. Wheeler, Chris H. Cramer
2000, Open-File Report 2000-484
We estimate site amplification at the location of a proposed bridge near Charleston, South Carolina. Model calculations indicate that amplification at periods of 1 s and longer is likely to be strongly influenced by the effects of a large contrast in shear-wave velocity at a depth of approximately 1 km (3,000 ft). On-site...

A.F. Moench, Stephen P. Garabedian, Denis R. LeBlanc
2000, Open-File Report 2000-485
An aquifer test conducted in a sand and gravel, glacial outwash deposit on Cape Cod, Massachusetts was analyzed by means of a model for flow to a partially penetrating well in a homogeneous, anisotropic unconfined aquifer. The model is designed to account for all significant mechanisms expected to influence drawdown...

Preliminary bathymetry of Shoup Basin and late Holocene changes of Shoup Glacier, Alaska
Austin Post, R.J. Viens
2000, Water-Resources Investigations Report 94-4093
Shoup Glacier is a retreating, tidewater-calving glacier in northeast Prince William Sound, Alaska. Historical records, vegetation distribution, and sediment depth in Shoup Bay indicate that the glacier reached a late Holocene maximum at the mouth of Shoup Bay prior to 1750. When first observed around 1900, the terminus was stable...

A field study was conducted between August 16-27, 1999, to provide the first direct measurements of the benthic flux of dissolved (0.2-micron filtered) solutes between the bottom sediment and water column at two sites in Lake Coeur d'Alene, Idaho. Trace metals (namely, cadmium, copper, manganese, mercury species, and zinc) and...
Digital isostatic gravity map of the Nevada Test Site and vicinity, Nye, Lincoln, and Clark Counties, Nevada, and Inyo County, California

2000, Open-File Report 99-554-C
An isostatic gravity map of the Nevada Test Site area was prepared from publicly available gravity data (Ponce, 1997) and from gravity data recently collected by the U.S. Geological Survey (Mankinen and others, 1999; Morin and Blakely, 1999). Gravity data were processed using standard gravity data reduction techniques. Southwest Nevada is...
Water-resources-related information for the St. Croix Reservation and vicinity, Wisconsin

2000, Water-Resources Investigations Report 2000-4133
The St. Croix Chippewa Tribe is interested in documenting water-quality conditions in lakes and streams adjacent to their Reservation lands in northwestern Wisconsin and developing management plans to protect these water resources. This report provides the Tribe with a retrospective summary and analysis of available water-resources-related information for their Reservation...
Monitoring surface-water quality in Arizona: the fixed-station network
Saeid Tadayon
2000, Fact Sheet 028-00
Arizona is an arid State in which economic development is influenced largely by the quantity and quality of water and the location of adequate water supplies. In 1995, surface water supplied about 58 percent of total withdrawals in Arizona. Of the total amount of surface water used in 1995, about...
Water-quality data collected at Lake Anne, Reston, Virginia, 1997-1999
