Two-dimensional, steady-state model of ground-water flow, Nevada Test Site and vicinity, Nevada-California
R. K. Waddell
1982, Water-Resources Investigations Report 82-4085
A two-dimensional, steady-state model of ground-water flow beneath the Nevada Test Site and vicinity has been developed using inverse techniques. The area is underlain by clastic and carbonate rocks of Precambrian and Paleozoic age and by volcanic rocks and alluvium of Tertiary and Quaternary age that have been juxtaposed by...
Determination of the true density of pulverized coal samples
R.W. Stanton
1982, Open-File Report 82-835
A method using the gas-comparison pycnometer with helium gas as the penetrating medium measures precisely the true volume of a pulverized coal sample. The true density of a solid is calculated as the true unit volume of the solid exclusive of its pore space which is divided into the weight...
Effects of Late Cretaceous and Cenozoic faulting on the geology and hydrology of the coastal plain near the Savannah River, Georgia and South Carolina
R.E. Faye, D.C. Prowell
1982, Open-File Report 82-156
Geologic and hydrologic investigations by the U.S. Geological Survey have defined stratigraphic and hydraulic anomalies suggestive of faulting within Coastal Plain sediments between the Ogeechee River in east-central Georgia and the Edisto River in west-central South Carolina. Examination of borehole cuttings, cores, and geophysical logs from test wells indicate that...
A stormwater management model for the West Branch Brandywine Creek, Chester County, Pennsylvania
Ronald A. Sloto
1982, Water-Resources Investigations Report 81-73
Three subbasins in the West Branch Brandywine Creek watershed were modeled by the Dawby, Schaake, and Alley distributed routing rainfall- runoff model. The Honeybrook subbasin could not be calibrated because of nonrepresentative rainfall data. The Coatesville subbasin was calibrated, but not verified; the average standard error of estimate is 34...
Electrical studies at the proposed Wahmonie and Calico Hills nuclear waste sites, Nevada Test Site, Nye County, Nevada
D.B. Hoover, Michael P. Chornack, K.H. Nervick, M. M. Broker
1982, Open-File Report 82-466
Two sites in the southwest quadrant of the Nevada Test Site (NTS) were investigated as potential repositories for high-level nuclear waste. These are designated the Wahmonie and Calico Hills sites. The emplacement medium at both sites was to be an inferred intrusive body at shallow depth; the inference of the...
Water resources of the Black Hand Sandstone Member of the Cuyahoga Formation aquifers of Mississippian age in southeastern Ohio
S.E. Norris, G.C. Mayer
1982, Open-File Report 82-170
The Black Hand Sandstone Member of the Cuyahoga Formation and associated acquifers of Mississippian age, including the Allensville Conglomerate Member of the Logan Formation, (both members of the local usage) were investigated in a 1 ,500-square-mile area in southeastern Ohio. These aquifers are the chief sources of water beneath the...
New papers related to remote sensing of the earth
A. P. Colvocoresses, F.J. Doyle
1982, Open-File Report 82-237
Worldwide experience of many individuals and organizations with remote sensing data acquired from space, primarily Landsat-1, -2, and -3, has demonstrated its utility for land use classification, agricultural assessment, energy and resource exploration, and many other applications. There has been some reluctance to adopt these systems in operational programmes because...
Quality assurance practices for the chemical and biological analyses of water and fluvial sediments
Linda C. Friedman, David E. Erdmann
1982, Techniques of Water-Resources Investigations 05-A6
This chapter contains practices used by the U.S. Geological Survey to assure the quality of analytical data for water, fluvial sediment, and aquatic organisms. These practices are directed primarily toward personnel making water quality measurements. Some detail specific quality control techniques, others document quality assurance procedures being used by the...
