Update On Estimation Of Water Surface Elevation Probabilities For The Great Salt Lake, L. Douglas James, David S. Bowles, W. Robert James, Ronald V. Canfield Jan 1981

Update On Estimation Of Water Surface Elevation Probabilities For The Great Salt Lake, L. Douglas James, David S. Bowles, W. Robert James, Ronald V. Canfield

Reports

The techniques of operational hydrology, employing an autoregrssive moving average (ARMA (1,0) model were used to replicate historical patterns of streamflow into, precipitation on, and evaporation from the Great Salt Lake. The results were combined with a lake water balance model to simulate lake stage sequences beginning with known initial conditions and extending up to 125 years into the future and used to generate probability distributions for future lake stages. Starting with a spring 1980 high stage of 4200.45 ft msl, the best estimate is that the 1981 spring high will be 4200.19, but there is one change in four …

Phase 1 Inspection Report: National Dam Safety Program. Upper Mississippi - Kaskaskia - St. Louis Basin. Lake Bono Del Dam, Jefferson County, Missouri, Horner & Shifrin, Inc., St. Louis, Missouri Jan 1981

Phase 1 Inspection Report: National Dam Safety Program. Upper Mississippi - Kaskaskia - St. Louis Basin. Lake Bono Del Dam, Jefferson County, Missouri, Horner & Shifrin, Inc., St. Louis, Missouri

Missouri Dam Safety Inspection Reports

This report presents the results of field inspection and evaluation of the Lake Bono Del Dam (MO 30434):

It was prepared under the National Program of Inspection of Non-Federal Dams.

This dam has been classified as unsafe, non-emergency by the St. Louis District as a result of the application of the following criteria:

1) Spillway will not pass 50 percent of the Probable Maximum Flood without overtopping the dam.

2) Overtopping of the dam could result in failure of the dam.

3) Dam failure significantly increases the hazard to loss of life downstream.

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 …


A Laboratory Evaluation Of Leachate From The Jim Bridger Power Plant Scrubber Wastes, V. Dean Adams, Mary E. Pitts, Megan J. Dyer Jan 1981

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 …


Transverse Thermal Response Of A Composite Bridge, Michael J. Filla Jan 1981

Transverse Thermal Response Of A Composite Bridge, Michael J. Filla

Masters Theses

"A two-span, composite-design, test structure was subjected to thermal loading. The resultant longitudinal and transverse response was correlated with that calculated by a prior theoretical procedure. The theoretical procedure was reconfirmed for longitudinal stress, and indicated within reasonable probability for transverse stress. No measurable diaphragm influence was observed"--Abstract, page iii.

Load And Resistance Factor Design Of Cold-Formed Steel Structural Members, Boonsong Supornsilaphachai Jan 1981

Load And Resistance Factor Design Of Cold-Formed Steel Structural Members, Boonsong Supornsilaphachai

Doctoral Dissertations

"In a traditional design, the Allowable Stress method has long been used for the design of cold-formed steel structures. In this design approach, the allowable stress is always used to prevent the possible structural failure by using an appropriate factor of safety selected primarily on the basis of engineering judgment and long-time experience.

Recently, the concepts of risk and reliability analysis have been successfully applied to many fields of engineering. By applying the theories of probability and statistics, the load and resistance design criteria for steel structures have been developed for the design of hot-rolled steel shapes and built-up members. …

An Investigation Of The Dynamic Response Of The Activated Sludge Process, Tin-Bai Pan Dec 1980

An Investigation Of The Dynamic Response Of The Activated Sludge Process, Tin-Bai Pan

Dissertations

A new mathematical model, derived from first principles of mass balance, is proposed for describing the mass transfer response of an activated sludge aeration tank in terms of a fluidized bed. The operational data to verify the proposed model were taken from an existing conventional wastewater treatment plant and a bench scale pilot plant.

The mass transfer rate, (KdAs), was presented by an empirical dimensionless group function as follows:

((KdAs)Dp/Dv) = fAc (uDp/ν)a ((ν/Dν)(MLSS))b

Or

Sh = f(Ac/As ) …


Bulletin 3929 - Irrigation In Western Australia, K S. Cole Dec 1980

Bulletin 3929 - Irrigation In Western Australia, K S. Cole

Bulletins - 3000 - 3999

Irrigation is essential in many parts of the world to produce essential food and profitable cash crops. Generally, those areas of land with less than 360 mm of rain spread over a distinct wet season of several months cannot grow crops for food or cash on rainfall alone. Then irrigation becomes necessary unless some peculiarity such as an oasis exists.
