Geohydrologic aspects for siting and design of low-level radioactive-waste disposal
M. S. Bedinger
1989, Circular 1034
The objective for siting and design of low-level radioactive-waste repository sites is to isolate the waste from the biosphere until the waste no longer poses an unacceptable hazard as a result of radioactive decay. Low-level radioactive waste commonly is isolated at shallow depths with various engineered features to stabilize the...

Sedimentation Survey of Lago Loiza, Puerto Rico, July 1985
Ferdinand Quinones, Bruce Green, Luis Santiago
1989, Water-Resources Investigations Report 87-4019
A survey of the sedimentation of Lago Loiza (Carraizo), in north-central Puerto Rico was conducted during July 1985. The survey showed that the actual capacity of the reservoir has declined from 21,700 acre-ft in 1953 to about 10,100 acre-ft in 1985. Sedimentation is depleting the reservoir 's capacity at an...

Documentation of computer programs to compute and display pathlines using results from the U.S. Geological Survey modular three-dimensional finite-difference ground-water flow model
David W. Pollock
1989, Open-File Report 89-381
A particle tracking post-processing package was developed to compute three-dimensional path lines based on output from steady-state simulations obtained with the U.S. Geological Survey modular 3-dimensional finite difference groundwater flow model. The package consists of two FORTRAN 77 computer programs: (1) MODPATH, which calculates pathlines, and (2) MODPATH-PLOT, which presents...

Geologic map of the Cape Disappointment-Naselle River area, Pacific and Wahkiakum counties, Washington
R.E. Wells
1989, IMAP 1832
The Cape Disappointment-Naselle River area is in southwestern Washington at the mouth of the Columbia River. The area encompasses several major estuaries and their adjacent highlands, which reach elevations of about 2,000 feet. Rainfall is abundant and produces heavy vegetation and deep weathering of the bedrock. Natural bedrock exposures are...

Water-related scientific activities of the U.S. Geological Survey in Nevada, fiscal years 1985-89
Kathryn C. Kilroy (compiler)
1989, Open-File Report 89-264
The U.S. Geological Survey has been collecting water resources data in Nevada since 1890. Most of the projects in the current Nevada District program can be classified as either basic-data acquisition (about 25%) or hydrologic interpretation (about 75 %). About 52% of the activities are supported by cooperative agreements with...

Metamorphosed strata of sedimentary origin underlie the upland surface of western Connecticut, and nonmetamorphosed sedimentary strata underlie the adjacent lowland surface of central Connecticut. The metamorphic rocks consist chiefly of micaceous schists and gneisses, with minor amounts of pegmatite, amphibolite, and metaquartzite. These rocks represent three formations. They are, in...
Streamflow and water-quality data for Little Scrubgrass Creek basin, Venango and Butler counties, Pennsylvania, December 1987 - November 1988

1989, Open-File Report 89-577
Streamflow and water-quality data were collected throughout the Little Scrubgrass Creek basin, Venango and Butler Counties, Pennsylvania, from December 1987 to November 1988, to determine the prevailing quality of surface water throughout the basin. This data will assist the Pennsylvania Department of Environmental Resources during its review of coal mine...
