Estimation Of Water Surface Elevation Probabilities And Associated Damages For The Great Salt Lake, L. Douglas James, David S. Bowles, W. Robert James, Ronald V. Canfield
Estimation Of Water Surface Elevation Probabilities And Associated Damages For The Great Salt Lake, L. Douglas James, David S. Bowles, W. Robert James, Ronald V. Canfield
Reports
Rising water surface elevations in perennial terminal lakes threaten major damages to shoreline industrial plants, transportation routs, and wetlands. Falling elevations increase pumping costs for industries extracting minerals from the lake water and reduce the quality of shoreline recreation. The managers of these properties need information on future lake level probabilities for planning, and public agencies need information on both probabilities and damages to determine whether lake level control is justified. Standard methods for estimating flood frequency and damages in riverine areas do not work well for terminal lakes because of the interdependency in annual peaks and the long advanced …

Program Development Plan For An Operational Cloud Seeding Project In Utah With Evaluation Included, Geoffrey E. Hill
Reports
- Operation Framework
In the arid climate of Southern and Central Utah, there is a continuing need to augment water supplies. While much of the water is needed for summertime use, particularly for irrigation, most of the available water is supplied by winter storms. Therefore, it is for the augmentation of the water stored naturally as snowpack at higher elevations that cloud seeding can make its greatest contribution.
Over the past several years, an attempt has been made to augment the snowpack by cloud seeding. Although there is a physical basis for expecting an increase in precipitation from a scientifically managed …

An Economic Evaluation Of The Salinity Impacts From Energy Development: The Case Of The Upper Colorado River Basin, Rangesan Narayanan, Sumol Padungchai, A. Bruce Bishop
An Economic Evaluation Of The Salinity Impacts From Energy Development: The Case Of The Upper Colorado River Basin, Rangesan Narayanan, Sumol Padungchai, A. Bruce Bishop
Reports
To analyze the effect of potential energy development on water allocation and water quality in the Upper Colorado River Basin, a linear programming model is formulated. Using the model, changes in salinity are predicted. Further, least-cost strategies to maintain the established numeric salinity criteria through both structural and nonstructural alternatives are developed. The effectiveness of alternative control measures are examined within given institutional constraints. Based on cost-benefit analysis, optimal salinity levels over time are proposed. The economic feasibility of presently planned strucutral measures to reduce salinity is investigated and contrasted with nonstructural alternatives.

Erosion Control During Highway Construction: Volume 1, Calvin G. Clyde, C. Earl Israelsen, Paul E. Packer
Reports
Summary: Highway constuction as we know it today is a high-risk activity with respect to engendering soil erosion. In earlier days of road building, when rights-of-way were generally narrow and excavations mostly shollow, erosion was rarely a serious problem. Only occasionally was it considered necessary to design and apply specific measures for erosion control. With the advent of the superhighway involving far greater widths of right-of-way, and much deeper disturbance of the natural ground to affort the horizontal and vertical highway geometry necessary for high-speed travel, came a several fold increase in erosion potential and a direct need for specific …
