A Galerkin finite-element flow model to predict the transient response of a radially symmetric aquifer
Thomas E. Reilly
1984, Water Supply Paper 2198
A computer program developed to evaluate radial flow of ground water, such as at a pumping well, recharge basin, or injection well, is capable of simulating anisotropic, inhomogenous, confined, or pseudo-unconfined (constant saturated thickness) conditions. Results compare well with those calculated from published analytical and model solutions. The program is...
Ideas for clear technical writing
B.P. Robinson
1984, Open-File Report 83-867
The three greatest obstacles to clear technical-report writing are probably (1) imprecise words, (2) wordiness, and (3) poorly constructed sentences. Examples of category 1 include abstract words, jargon, and vogue words; of category 2, sentences containing impersonal construction superfluous words; and of category 3, sentences lacking parallel construction and proper...
Dry tilt network at Mount Rainier, Washington
Daniel Dzurisin, Daniel J. Johnson, R.B. Symonds
1984, Open-File Report 83-277
In addition to its primary responsibility of monitoring active Mount St. Helens, the David A. Johnston Cascades Volcano Observatory (CVO) has been charged with obtaining baseline geodetic and geochemical information at each of the other potentially active Cascade volcanoes. Dry tilt and/or trilateration networks were established during 1975-82 at Mount...
Velocity profile, water-surface slope, and bed-material size for selected streams in Colorado
J.P. Marchand, R.D. Jarrett, L.L. Jones
1984, Open-File Report 84-733
Existing methods for determining the mean velocity in a vertical sampling section do not address the conditions present in high-gradient, shallow-depth streams common to mountainous regions such as Colorado. The report presents velocity-profile data that were collected for 11 streamflow-gaging stations in Colorado using both a standard Price type AA...
Geohydrology of rocks penetrated by test well UE-25p#1, Yucca Mountain area, Nye County, Nevada
R. W. Craig, J. H. Robison
1984, Water-Resources Investigations Report 84-4248
Test well UE-25pNo1 was drilled in cooperation with the U.S. Department of Energy in the southwestern part of the Nevada Test Site, for investigations related to the isolation of high-level nuclear wastes. Rocks penetrated in the well are predominantly ash-flow tuffs of Tertiary age to a depth of 1,244 meters...
Traveltime and dispersion in the Potomac River, Cumberland, Maryland, to Washington, D.C.
K.R. Taylor, R.W. James, B.M. Helinsky
1984, Open-File Report 83-861
Data from two traveltime and dispersion studies, using rhodamine dye, are used to develop a generalized procedure for predicting traveltime and downstream concentrations resulting from spillage of water-soluble substances at any point along the Potomac River from Cumberland, Maryland, to Washington, D.C. The procedure will allow the approximate solution to...
Calibration and verification of a rainfall-runoff model and a runoff-quality model for several urban basins in the Denver metropolitan area, Colorado
J. B. Lindner-Lunsford, S. R. Ellis
1984, Water-Resources Investigations Report 83-4286
The U.S. Geological Survey 's Distributed Routing Rainfall-Runoff Model--Version II was calibrated and verified for five urban basins in the Denver metropolitan area. Land-use types in the basins were light commerical, multifamily housing, single-family housing, and a shopping center. The overall accuracy of model predictions of peak flows and runoff...
Leperditicopid ostracodes from Ordovician rocks of Kentucky and nearby states and characteristic features of the order Leperditicopida
J.M. Berdan
1984, Professional Paper 1066-J
Leperditicopid ostracodes from the Ordovician formations of Kentucky occur in micritic to fine-grained carbonate rocks believed to represent shallow-water facies. They are found at widely separated horizons in the Middle Ordovician High Bridge Group, the Middle and Upper Ordovician Lexington Limestone, and the Upper Ordovician Ashlock, Bull Fork, and Drakes...
