Hydrosalinity Impacts Of Conservation Measures In The Sevier River Basin, Eugene K. Israelsen Jan 1981

Hydrosalinity Impacts Of Conservation Measures In The Sevier River Basin, Eugene K. Israelsen

Reports

The Sevier River Basin is a water short basin wherein upstream diversions not consumptively used become the water right for downstream users. The diversion-return cycle occurs several times as the stream travels from its mountain source areas to the terminal lake at the lower end of the basin. This study dealt with the proposed implementation of conservation measures which would wawste less diverted water and allow for irrigation of additional acres. The objective was to predict the hydrosalinity impacts of the implementation of these measures. The results indicated that increased consumptive use in the upper areas would decrease the water …

A Laboratory Evaluation Of Leachate From The Jim Bridger Power Plant Scrubber Wastes, V. Dean Adams, Mary E. Pitts, Megan J. Dyer

Reports

Introduction: Scrubber wastes obtained in an affort to limit air pollution generated by coal-fired pwoer plants may contribute to another possible sources of pollution. To date, scrubber wastse have been in a liquid phase which causes disposal problems partially due to the liquid characteristics. The use of solid scrubber wastes and the land deposition of such wastes is proposed. The feasibility of solid scrubber wastes disposal in landfills is under question. The primary area of concern is the effect that water percolation through such wastes would have on groundwater quality parameters. Contamination could result either as precipitation travels downward through …

Economic Impacts Of Irrigation Technologies In The Sevier River Basin, Theodore R. Frickel, Rangesan Narayanan Jan 1981

Economic Impacts Of Irrigation Technologies In The Sevier River Basin, Theodore R. Frickel, Rangesan Narayanan

Reports

The economic well-being of the semiarid intermountain area requires efficent use of available water supplies. Agriculture, the major water-consuming industry, depends on irrigation water. The adoption of sprinkler systems that increase on-farm irrigation "efficiencies" and the area which can be irrigated from upstream diversions may interfere with the "tenure" of downstream water rights. These downstream effects need to be evaluated before allowing farmers to use the water "saved" to irrigate additional acreages or crops to obtain greater profits. The problem in letting farms expand their irrigated acreage is that the individual farmer increases his profits through increased consumptive use. The …

Selected Biological Characteristics Of Streams In The Southeastern Uinta Basin, Utah And Colorado, United States Geological Survey Jan 1981

Selected Biological Characteristics Of Streams In The Southeastern Uinta Basin, Utah And Colorado, United States Geological Survey

All U.S. Government Documents (Utah Regional Depository)

Biological sampling was carried out during 1976-78 in five streams in the southeastern Uinta Basin, Utah and Colorado, in order to provide baseline water-quality data for an area of potential oil-shale development. The biological activity in the streams sampled generally is limited by physical factors more so than by chemical constituents and plant nutrients. Characteristics of streamflow, such as high turbidity, fluctuating water levels, and moderate to high salinity, limit production of flora and fauna biomass.

A Quantitative Test Of Unimolecular Rate Theory In The Multi‐Photon Dissociation Of Cf2Cfcl, John C. Stephenson, Stephen E. Bialkowski, David S. King, Everet Thiele, James Stone, Myron F. Goodman Jan 1981

A Quantitative Test Of Unimolecular Rate Theory In The Multi‐Photon Dissociation Of Cf2Cfcl, John C. Stephenson, Stephen E. Bialkowski, David S. King, Everet Thiele, James Stone, Myron F. Goodman

Stephen E. Bialkowski

We have measured the distribution of total energy in reaction products for the CO2 laser‐induced MPD: CF2CFCl→CF2+CFC1. From a separate study of MPD rates as a function of laser intensity and inert buffer gas pressure, reliable estimates of the radiative pumping rates are known for this reaction. These results, when analyzed together, allow us to extract a unimolecular A factor from the MPD data. The determined value A = 3×1016 sec−1 agrees well with estimates based on independent thermal data.
