MULTILAYERED, PRIORITY-BASED SIMULATION OF CONJUNCTIVE FACILITIES

A network flow programming-based model, KCOM, was developed to simulate water allocation and distribution in the surface water system of Kern County, California. The model will help the California Department of Water Resources plan the proposed Kern Water Bank conjunctive-use project. KCOM incorporates recharge and pumping features to allow simulation of both surface and subsurface water distribution. Network flow programming-based simulation was chosen for KCOM because of its generality, flexibility, speed, and superior ability to reflect complex water allocation policies. The water allocation capabilities of network flow programming-based simulation were enhanced in KCOM by the development of a sequential flow allocation technique, in which sources are allocated in different layers to meet only demands with authorized access to those sources. A validation simulation demonstrates the model's capabilities, and sensitivity analysis underscores the need for improvement of the data used to describe the system. Recommendations are made for the improvement of KCOM.
