Interactive Modification Of Quadratic Multiobjective Water Resources Planning Strategies, Paul J. Killian, Richard C. Peralta

Technical Reports

An interactive method is presented for modifying a compromise solution to a multiobjective water resources planning stategy by changing constraining conditions on regional objectives and local variables. The method is illustrated by modifying a bicriterion, sustained groundwater withdrawal strategy for minimizing the cost of meeting regional water demand on the Arkansas Grand Prairie. The strategy was developed using a model in which the finite difference form of the two-dimensional groundwater flow equation is embedded in an optimization process. The quadratic optimization is accomplished by utilizing the General Differential Algorithm to obtain values of the drawdown, pumping rate, and recharge rate …

Development Of Optimal Sustained Yield Groundwater Withdrawal Strategies For The Boeuf-Tensas Basin In Arkansas, Richard C. Peralta, Bithin Datta, Jamal Solaimanian, Paul J. Killian, Amin Yazdanian

Technical Reports

The goal of this study ia to develop sustained yield pumping (discharge via wells) strategies for the Boeuf-Tensaa Basin area. The demarkation of the Boeut-Tensas area is described in the Arkansas State Vater Plan (Arkansas Soil and Water Conservation Commission. 1984). The Boeuf-Teneas Basin ia a highly developed agricultural region located in the southeast corner of Arkansas. Hydrogeologically. it is part of the Bayou Bartholomew/Alluvial Aquifer System (Broom and Reed. 1973). Before describing the Boeuf-Tensas Basin, the Bayou Bartholomew region should be discussed.

Projections Of Agricultural And Fish And Wildlife Water Demand In The Ouachita River Basin: A Linear Programming Approach, Mark J. Cochran, Mike Tessaro, J. Martin Redfern, Larry Childress, E. Moye Rutledge, Rob Raskin, Robert N. Shulstad

Technical Reports

The availability of an abundant water supply has been a major resource of the Ouachita River Basin. In recent years, water requirements for a number of uses have increased, raising the concern that future water shortages could occur in the basin. The purpose of the study reported here was to estimate future water demand for irrigation, commercial fisheries, and fish and wildlife uses.

Western Water Law in Transition (Summer Conference, June 3-5)

Conference organizers and/or faculty included University of Colorado School of Law professors James N. Corbridge, Jr., Lawrence J. MacDonnell, Richard B. Collins, David H. Getches and Charles F. Wilkinson.

The prior appropriation doctrine has governed the allocation and use of water in the western United States since the 1850s. The shifting nature of water demand is bringing about changes in the traditional legal system. This conference will consider the fundamental principles of the prior appropriation doctrine together with the important new developments in the law now underway throughout the West.

Water Quality For Irrigation, P R. George

Journal of the Department of Agriculture, Western Australia, Series 4

Although irrigation and salinity problems are frequently inseperable, there is a range of management methods that can be used to handle marginal quality water. Freuently these methods are simple, but require careful planning.

The wide range in tolerance of crops to salinity can be exploiter to ensure that appropriate crops are selected for the water available.

Because crops vary in their sensitivity to salt uptake in the leaves or the roots, watering methods can be changed to avoid problems. For profitable production enough water should be applied to ensure adequate water is available for plant growth as well as to …
