• The Arizona Water Commission's Central Arizona Project Water Allocation Model System

      The purpose and operation of the Central Arizona Project water allocation model system are described, based on a system analysis approach developed over the past 30 years into an interdisciplinary science for the study and resolution of complex technical management problems. The system utilizes mathematical and other simulation models designed for computer operations to effectively solve such problems as the CAP faces including those concerned with social and economic considerations. The model is composed of two major components: (1) a linear program designed to determine the optimal allocation of all sources of water to all demands and, (2) a hydrologic simulator capable of reflecting the impact of distribution alternatives on per-unit cost of delivery. The model, currently being use, has substantially contributed to a greater understanding of water usage potential in Arizona.
    • An Economic Analysis of the Central Arizona Project

      An economic evaluation of the Central Arizona Project was conducted with a goal of developing a simulation model of CAP costs, water operations and capital repayment alternatives. This model was compared to the actual cost experience of the Metropolitan Water District of Southern California for a realistic assessment. In addition, an effort was made to consider some of the indirect impacts of the CAP, and the overall economic outlook was summarized. In devising the simulation model CAP capital costs, CAP power supply and CAP water supply factors were considered along with user charges, management alternatives, and operations, maintenance and repair costs.
