The Apalachicola-Chattahoochee-Flint (ACF) River System supports a diverse array of instream and out-of-stream uses and values, including ecological support, recreation, power generation, municipal water supply, and maintenance of water quality. A simulation model program has been developed to better understand both the sensitivity of each water demand to the systemwide demands as well as the sensitivity to uncertain model inputs such as inflows and evaporation. The ACF simulation model is written in Visual Basic for Applications (VBA) programming language so that the sensitivity of each modeling parameter can be tested through varying the model parameters for multiple automated model runs The model’s ability to test the effects of different modeling parameters and inputs help provide a way in which the most effective tradeoffs can be developed. The possible applications of such a simulation tool include the evaluation of peaking power requirements during reservoir operation, identifying the most effective reservoir balancing alternatives, and evaluation of the effects of conservation on reservoir levels.
