Gas-film coefficients for streams
R. E. Rathbun, D. Y. Tai
1983, Journal of Environmental Engineering (109) 1111-1127
Equations for predicting the gas-film coefficient for the volatilization of organic solutes from streams are developed. The film coefficient is a function of windspeed and water temperature. The dependence of the coefficient on windspeed is determined from published information on the evaporation of water from a canal. The dependence of...
Conjunctive use of groundwater and surface water for irrigated agriculture: Risk aversion
John D. Bredehoeft, Richard A. Young
1983, Water Resources Research (19) 1111-1121
In examining the South Platte system in Colorado where surface water and groundwater are used conjunctively for irrigation, we find the actual installed well capacity is approximately sufficient to irrigate the entire area. This would appear to be an overinvestment in well capacity. In this paper we examine to what...

H.V. Leland
1983, Environmental Toxicology and Chemistry (2) 353-368
Morphological changes in hepatocytes of mature brown trout (Salmo trutta Linnaeus) and juvenile rainbow trout (Salmo gairdneri Richardson), accompanying chronic exposures to copper and zinc, were examined by transmission electron microscopy. At a concentration of copper not inhibitory to the final stages of gonadal development or spawning of brown trout,...

More than 3 billion gallons of water are pumped daily from the limestone aquifer; and...
A digital-computer model of the Big Sioux aquifer in Minnehaha County, South Dakota
N.C. Koch
1982, Water-Resources Investigations Report 82-4064
A finite-difference digital model was used to simulate steady-state conditions of the Big Sioux aquifer in Minnehaha County. Average water levels and average base flow discharge (4.9 cu ft/s) of the Big Sioux River were based on data from 1970 through 1979. The computer model was calibrated for transient conditions...
Hydrologic-information needs for oil-shale development, northwestern Colorado
O.J. Taylor
1982, Water-Resources Investigations Report 82-4076
Hydrologic information is not adequate for proper development of the large oil-shale reserves of Piceance basin in northwestern Colorado. Exploratory drilling and aquifer testing are needed to define the hydrologic system, to provide wells for aquifer testing, to design mine-drainage techniques, and to explore for additional water supplies. Sampling networks...
Water information for northwestern Missouri: A planning document
John Skelton, Edward Joseph Harvey, Don E. Miller
1982, Water-Resources Investigations Report 82-27
Water supplies are limited in much of northwestern Missouri, and water-resources data also are limited. This report presents a summary of hydrologic data and an evaluation of areas where additional hydrologic data are needed to provide a data base suitable for use in making decisions regarding future water development.The largest...

Base flow of streams on Long Island, New York
Richard J. Reynolds
1982, Water-Resources Investigations Report 81-48
On Long Island, base flow under nonurbanized conditions constitutes 90 to 95% of total stream discharge. Base-flow data from 19 continuously gaged streams are presented as monthly mean and annual mean discharge for water years 1960-75, which includes the 1962-66 drought. The data were derived by hydrograph-separation procedures that isolate...
