Application of Specialized Optimization Techniques for Water Quality and Quantity Management with Respect to Planning for the Trinity River Basin

摘要

Techniques are developed and presented forming the basis for the development of water management plans which include consideration of water quality and quantity in the same model. The methodology described in this report utilizes a dynamic programming approach in devising the mix of waste treatment, water treatment, and low flow augmentation to minimize the total cost of developing and operating the system while being regulatory in aesthetic restrictions. Use of these procedures permits the evaluating of the trade-off between costs for water and waste treatment and reservoir releases for quality control plus a consideration of the economic returns afforded by recreational use of the water. This investigation represents more of a systems approach to water quality management than the studies heretofore completed. Advances in the optimization of nonserial multistage systems are presented in the report along with a discussion of the computational solution of such systems. Example problems are included illustrating the use of the techniques. (WRSIC abstract).
