Optimal Expansion of a Water Resource System and Issues of Water Allocation and Utilization: Umatilla River Basin, Oregon

摘要

This study explored the merits of scheduling water resource project facilities on the basis of the anticipated economic benefits provided. Using the Umatilla River Basin in northeast Oregon as a case study example, the facilities (and their alternatives) of a previously-planned Federal water resource development project in that area were analyzed relative to the magnitude and timing of anticipated costs and benefits, focusing on irrigated agriculture and fishery development/enhancement benefits. A basic scheduling model was designed, aimed at maximizing the present value of net benefits (PVNB) inherent in an optimally-timed set of facilities subject to an annual budget constraint.
