James W. Warner
1979, Open-File Report 79-676
Diisopropylmethylphosphonate (DIMP) is an organic compound produced as a byproduct of the manufacture and detoxification of GB nerve gas. Ground-water contamination by DIMP from the disposal of wastes into unlined surface ponds at the Rocky Mountain Arsenal occurred from 1952 to 1956. A digital-transport model was used to determine the...

Urban storm-runoff modelling; Madison, Wisconsin
R. Stephen Grant, Gerald Goddard
1979, Open-File Report 79-1273
The Illinois Urban Drainage Area Simulator was used to analyze the effects that (1) physical changes to storm-sewer conduits, and (2) increased runoff detention and infiltration would have on storm runoff in four urban basins in Madison, Wisconsin. The model was calibrated using monitoring data for the four basins collected...
Water resources of the Marquette Iron Range area, Marquette County, Michigan
N.G. Grannemann
1979, Open-File Report 79-1339
Dependable water supplies are vital to the mining industry in the Marquette Iron Range in Michigan. Development of processes that concentrate and pelletize low-grade iron ore has permitted mining to expand during the past two decades. Water demand has increased both for iron ore concentration processes and for the area...

William G. Wilber, James G. Peters, Mark A. Ayers, Charles G. Crawford
1979, Open-File Report 79-1062
The Indiana State Board of Health is developing a State water-quality management plan that includes the establishing of limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in Cedar Creek was used to develop alternatives for future waste loadings that would be compatible with Indiana...
An appraisal of pumping effects on the Edgeley Aquifer, La Moure County, North Dakota, as determined by a digital model
M. R. Burkart
1979, Open-File Report 79-748
A finite-difference digital model simulated hydrologic conditions in the Edgeley aquifer, which is an unconfined glacial-drift aquifer. The calibrated model supported the hypothesis that under natural steady-state conditions, recharge is from precipitation and discharge is through evapotranspiration. This hypothesis was further supported by comparing simulated water levels to observed water...

A mineral survey of the Minarets Wilderness area and adjacent areas in the central Sierra Nevada, Calif., was conducted during 1973 through 1975. The total area covers about 620 km2 (237 sq mi) in the Sierra and Inyo National Forests, of which about 440 km2 (170 sq mi) are within...
Hydrologic and human aspects of the 1976-77 drought
Howard F. Matthai
1979, Professional Paper 1130
The drought of 1976-77 was the most severe in at least 50 years in many parts of the United States. Record low amounts of rainfall, snowfall, and runoff, and increased withdrawals of ground water were prevalent. The use of carry-over storage in reservoirs during 1976 maintained streamflow at near normal...
Modeling highly transient flow, mass, and heat transport in the Chattahoochee River near Atlanta, Georgia
Harvey E. Jobson, Thomas N. Keefer
1979, Professional Paper 1136
A coupled flow-temperature model has been developed and verified for a 27.9-km reach of the Chattahoochee River between Buford Dam and Norcross, Ga. Flow in this reach of the Chattahoochee is continuous but highly regulated by Buford Dam, a flood-control and hydroelectric facility located near Buford, Ga. Calibration and verification...

J. Karen Felmlee, Robert Allen Cadigan
1979, Open-File Report 79-974
Radium and uranium concentrations in water from 37 wells tapping the aquifer system of the Dakota Sandstone and Purgatoire Formation in southwestern Pueblo County, Colorado, have a wide range of values and define several areas of high radioactivity in the ground water. Radium ranges from 0.3 to 420 picocuries per...
Hydrometeorological model for streamflow prediction
Wendell V. Tangborn
1979, Open-File Report 79-741
The hydrometeorological model described in this manual was developed to predict seasonal streamflow from water in storage in a basin using streamflow and precipitation data. The model, as described, applies specifically to the Skokomish, Nisqually, and Cowlitz Rivers, in Washington State, and more generally to streams in other regions that...
A single-degree-of-freedom model for non-linear soil amplification
Mustafa Ozder Erdik
1979, Open-File Report 79-592
For proper understanding of soil behavior during earthquakes and assessment of a realistic surface motion, studies of the large-strain dynamic response of non-linear hysteretic soil systems are indispensable. Most of the presently available studies are based on the assumption that the response of a soil deposit is mainly due to...

Jeffrey J. Daniels, James Henry Scott, Bruce D. Smith
1979, Open-File Report 79-585
Borehole geophysical studies across a uranium deposit in the Jackson Group, South Texas, show the three geochemical environments often associated with uranium roll-type deposits: an altered (oxidized) zone, an ore zone, and an unaltered (reduced) zone. Mineralogic analysis of the total sulfides contained in the drill core shows only slight...

Gary C. Curtin, Harley D. King, J. M. Nishi
1979, Open-File Report 79-710
Leaching studies of subalpine forest soils collected at seven sites in Colorado and Idaho show that copper, cobalt, chromium, magnesium, barium, tin, strontium, and yttrium are highly mobile elements in these soils; that zirconium, lanthanum, nickel, and scandium are moderately mobile; and that titanium is rather immobile. Furthermore, the results...

Eugene B. Fabiano, W. J. Jones, Norman W. Peddie
1979, Circular 810
Approximately 24,000 measurements taken from 1900 to 1974 were analyzed by least-squares methods to produce a series of five magnetic charts of the United States for 1975. A feature of the analysis, differing from techniques used for previous editions of the national chart, is that analytic models define the regional...
