Optimal Conjunctive Management of Coupled Surface Water and Groundwater Systems Using Gradient Dynamic Programming
Abstract
This thesis presents an analytic procedure to derive rules for managing a conjunctive use system. In this thesis, system management refers to the specification of optimal controls: decisions regarding the release and allocation of water. The procedure is applied to a proposed conjunctive use system of practical interest, where the facilities have predetermined characteristics and where control decisions are affected by uncertain autocorrelated inputs. Optimal decisions are determined by applying the optimization method of gradient dynamic programming to a numerical model of the conjunctive use system. The resulting optimal decisions demonstrate that application of the analytic procedure can greatly improve the management of a conjunctive use system. These decisions are significantly more efficient than those that result from application of heuristic rules. Also, the analytic procedure incorporates the effect of autocorrelation, and the resulting optimal decisions demonstrate that autocorrelation is important in the control of conjunctive use systems because of the different capabilities and constraints that surface reservoir storage and aquifer storage present.
