Optimizing Reservoir-Stream-Aquifer Interactions for Conjunctive Use and Hydropower Production

Abstract EN

Conjunctive management of water resources involves coordinating use of surface water and groundwater resources.

Very few simulation/optimization (S-O) models for stream-aquifer system management have included detailed interactions between groundwater, streams, and reservoir storage.

This paper presents an S-O model doing that via artificial neural network simulators and genetic algorithm optimizer for multiobjective conjunctive water use problems.

The model simultaneously addresses all significant flows including reservoir-stream-diversion-aquifer interactions in a more detailed manner than previous models.

The model simultaneously maximizes total water provided and hydropower production.

A penalty function implicitly poses constraints on state variables.

The model effectively finds feasible optimal solutions and the Pareto optimum.

Illustrated is application for planning water resource and minihydropower system development.
