Abstract:

A flood forecasting model has been developed for the Lower Colorado River Authority that can be used in a real-time framework to make decisions on reservoir operations during flooding. This real-time flood forecasting model is based upon state-of-the-art techniques for flood routing, rainfall-runoff modeling, and graphical display capability and is controlled by interactive software. An optimization model has also been developed to optimally determine the real-time operation of reservoirs under flooding conditions. The variables that are used in the mathematical model are: water surface elevations at all computational points; flow rates at all computational points; and gate operations at all gated reservoirs.
