Optimizing The Rapid Evolution Of Target Groundwater Potentiometric Surfaces, Richard C. Peralta, Krzysztof G. Kowalski

Civil and Environmental Engineering Faculty Publications

THE long-term availability of adequate groundwater for sustainable irrigated agricultural production can be assured by causing the evolution and maintenance of an appropriate potentiometric (piezometric) surface in utilized aquifers. By providing adequate saturated thickness and hydraulic gradients and heads. such a surface affords some protection from the effects of drought. economic: hardship, and environmental or legal complications. Procedures for determining desirable or optimal regional steady-state groundwater potentiometric surfaces have been reported by several researchers. An existing polcmiometric surface can be forced to evolve into a desirable 'target' surface if it is subjected through time to the proper combination of recharges …

Potential Arkansas And White Rivers Water Available For Diversion To The Grand Prairie, W. Douglass Dixon, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

At the present time. the rate of groundwater use in the Grand Prairie region of Arkansas exceeds natural replenishment of the underlying aquifer. Most of the groundwater is used for agricultural production. [f current agricultural water needs of the region are to be satisfied under sustained yield conditions. supplemental surface water will be required. The objective of this study is to assess the viability of the Arkansas and White Rivers as sources of supplemental water for meeting water needs in excess of those which can be met with groundwater.

Maintaining Target Groundwater Levels Using Goal‑Programming: Linear And Quadratic Methods, Amin Yazdanian, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

Sustained-yield groundwater management strategies can be designed to closely maintain preassigned 'target' levels. Quadratic and linear goal-programming objective functions are used in two distinct models which minimize the sum of differences between 'target' and regionally optimized sets of groundwater levels. Constraints and bounds imposed on extractions, recharge and heads in each model assure that developed strategies are physically feasible and sustainable. The linear model is computationally more time-efficient, but numerical difficulties due to equality constraints are encountered when it is applied to large groundwater systems_ The quadratic model requires less computer storage and is applied to the Grand Prairie of …

Optimal Modification Of Regional Potentiometric Surface Design For Groundwater Contaminant Containment, Bithin Datta, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

A procedure for optimal modification of a regional potentiometric surface designed solely on the basis of quantitative considerations, is presented. The modification in the potentiometric surface is necessary to incorporate groundwater quality criteria in a critical subsystem of the entire region. The resulting optimal regional potentiometric surface ensures: sustained groundwater yields from the aquifer, compliance with water quality constraints at critical cells of the sub· system (which are identified by a solute transport simulation model), and the most economic conjunctive management of surface and groundwater.

Web Crippling Of High Strength Cold-Formed Steel Beams, Chiravut Santaputra

Doctoral Dissertations

"The structural behavior of high strength cold-formed steel beams subjected primarily to web crippling was investigated analytically and experimentally. In this study hat sections and I-beams, formed from five different types of high strength sheet steels commonly used in the automobile industry, were investigated under various loading conditions. The yield strengths of these sheet steels vary from 58 to 165 ksi.

In addition to the test data gathered in this phase of study, the experimental results obtained from the beam tests conducted at Inland Steel Company and Ford Motor Company were carefully evaluated. The evaluation indicated that the present available …

An Investigation Of Signs For Median Crossovers, Gillian M. Worsey

Doctoral Dissertations

“This paper describes a study of advance warning signs for median crossovers on divided highways. Candidate crossover signs were identified from a literature review, survey of current State practices and discussions with FHWA personnel. Seven of these signs were selected for further testing in a laboratory study for legibility, understanding and driver preference. Sixty subjects representing a cross-section of drivers took part in the study, thirty at the Turner-Fairbanks Highway Research Center in McLean, Virginia and thirty at the University of Missouri--Rolla in Rolla, Missouri.

Two of the seven signs were word messages and five were symbolic signs. The results …

Water Quality Management Studies For Water Resources Development In The Bear River Basin, Darwin L. Sorensen, Craig Caupp, William J. Grenney, Steve Eberl, Jay J. Messer, Phillip Ludvigsen, Charles W. Ariss

Reports

Summary: The quality of water that develops in the proposed reservoirs of the Upper Bear River Storage Project will determine the possible uses of the water. Previous studies of water quality in the Bear River and its tributaries have reported water quality problems relating to nitrate ion, sanitary indicator bacteria, suspended solids, and phosphorus concentrations. Most point sources of water pollution inthe basin have been eliminated or improved in quality, but nonpoint sources of pollution continue to degrade the quality of the Bear River. Concentrations of phosphours have been sufficiently high to encourage dense algal growth and create eutrophic conditions …

Economic Evaluation Of Conservation Concepts For Municipal Water Systems, Trevor C. Hughes, Rangesan Narayanan, Mac Mckee, A. Bruce Bishop, Robert Leconte, Sumani Al-Hassan

Reports

Five concepts for conservation of municipal water supply are analyzed from an economic efficiency perspectice. They include: 1) seasonal pricing (for reduction of peak period water use), 2) dual water systems (separate high quality drinking water and untreated outdoor irrigation systems), 3) imported water transmission facility capacity optimization, 4) flow restricting devices, and 5) short-term rationing concepts. Optimization models, including generalized model generators, were developed for analysis of the first three concepts and demonstrated by applications to cities in Utah. The flow restricting device and short-term rationsing concept analyses applied approaches taken from the literature to example sites in Utah. …

Feasibility Of Incorporating Aquaculture, Solar Pond Energy, And Mineral Extraction Technologies To Control Localized Sources Of Salinity In River Systems, J. Paul Riley

Reports

Salinity poses a serious and continuing problem to the full utilization of water resources in many river basins of western U.S. A variety of management measures have been employed to mitigate the damaging effects of salinity on agricultural crops as well as on municipal and industrial uses of water. The Colorado River Basin Salinity Control Act illustrates the logic of addressing the problem on a basin wide basis under a strategy that give priority to those localized sources of salinity that contribute disproportionately large amounts of salt to the system. It remains then to devise control measures specific to each …
