A generalized river basin computer model called CONSIM is presented for management of the conjunctive use of surface and subsurface storage in an interconnected stream-aquifer system. The model simulates the hydrologic system and optimizes water allocation period by period based on costs, benefits, or water right priorities. The water resource system is configured as a least-cost flow network of nodes and links and solved by the out-of-kilter algorithm on a microcomputer. A user-interfaced management system is available for easily inputing, organizing, and editing data for any river basin to be simulated using CONSIM. In order to demonstrate the usefulness of the model, a case study section of the South Platte River basin in eastern Colorado was selected.
