User's guide for RIV2; a package for routing and accounting of river discharge for a modular, three-dimensional, finite-difference, ground- water flow model
Roger S. Miller
1988, Open-File Report 88-345
RIV2 is a package for the U.S. Geological Survey 's modular, three-dimensional, finite-difference, groundwater flow model developed by M. G. McDonald and A. W. Harbaugh that simulates river-discharge routing. RIV2 replaces RIVI, the original river package used in the model. RIV2 preserves the basic logic of RIV1, but better represents...
Distribution and variability of precipitation chemistry in the conterminous United States, January through December 1983
J. F. Rinella, T. L. Miller
1988, Open-File Report 87-558
Analysis of atmospheric precipitation samples, collected during the 1983 calendar year from 109 National Trends Network sites in the United States, are presented in this report. The sites were grouped into six geographical regions based on the chemical composition of the samples. Precipitation chemistry in these regions was influenced by...
Results of a geochemical survey, Aban Al Ahmar Quadrangle, Sheet 25F, Kingdom of Saudi Arabia
W. Roger Miller, M. A. Arnold
1988, Open-File Report 88-605
The interpretation of geochemical data from a regional survey of the Aban al Ahmar quadrangle resulted in the selection of areas for follow-up studies. The results of detailed geochemical studies of these areas, combined with field observation, resulted in the selection of areas of moderate to high mineral resource potential....
The U.S. Geological Survey Federal-State cooperative water- resources program; fiscal year 1987
B.K. Gilbert, William B. Mann IV
1988, Open-File Report 88-174
The U.S. Geological Survey 's Federal-State Cooperative Water Resources Program (50-50 matching of funds) started in Kansas in 1895. During fiscal year (FY) 1987, hydrologic data collection, investigations, and research are being conducted in every state, Puerto Rico, and several territories in cooperation with 940 state, regional and local agencies....
Radionuclides in ground water at the Idaho National Engineering Laboratory, Idaho
LeRoy L. Knobel, Larry J. Mann
1988, Open-File Report 88-731
Sampling for radionuclides in groundwater was conducted at the Idaho National Engineering Laboratory during September to November 5 1987. Water samples from 80 wells that obtain water from the Snake River Plain aquifer and 1 well that obtains water from a shallow, discontinuous perched-water body at the Radioactive Waste Management...
Annual yield and selected hydrologic data for the Arkansas River Basin compact, Arkansas-Oklahoma, 1987 water year
M. A. Moore, T.E. Lamb, L.D. Hauth
1988, Open-File Report 88-301
The computed annual yield and deficiency of the subbasins are defined in the Arkansas River Compact, Arkansas-Oklahoma, are given in tables. Actual runoff from the subbasins and depletion caused by major reservoirs in the compact area are also given in tabular form. Monthly, maximum, and mean discharges are shown for...
Runoff for selected sites in Shenandoah National Park, Virginia, July 18, 1981, through July 17, 1982
W.A. Gebert, David J. Graczyk, William R. Krug
1988, Open-File Report 88-98
Estimates of runoff for 56 sites within the Shenandoah National Park were made by the U.S. Geological Survey for the Direct/Delayed Response Project that is being conducted by the U.S. Environmental Protection Agency. The purpose of that project is to determine the long-term effects of acidic deposition on surface-water chemistry....
Field conditions at the Maricopa Agricultural Center, Maricopa County, Arizona, June 13, 1988
Sandra J. Owen-Joyce
1988, Open-File Report 88-708
Field conditions were documented during the Landsat satellite overpass of the Maricopa Agricultural Center, Maricopa County, Arizona, on June 13, 1988. Crop types were mapped and photographed for each demonstration farm field. Field conditions described include irrigation, cultivation, and orientation of rows. Field and photographic descriptions are presented in tabular...
