Testing of an Optimization-Simulation Model for Real-Time Flood Operation of River-Reservoir Systems

A new methodology was developed for the real-time determination gate control operations of a river-reservoir system to minimize flooding conditions. The is based upon an optimization-simulation model approach interfacing genetic algorithm within MATLAB with simulation software short-term rainfall forecasting, rainfall–runoff modeling (HEC-HMS), and one-dimensional (1D), two-dimensional (2D), combined 1D 2D unsteady flow models (HEC-RAS). Both data from next-generation radar (NEXRAD) gaging stations, forecasted are needed make decisions (reservoir releases) in so that at time t, known over future time-period (?t) t + ?t can be forecasted. This used manage reservoir release schedules (optimal operations) before, during, after event. Through observations optimal controls, downstream water surface elevations controlled avoid exceedance threshold flood levels target locations throughout damage. In example application, actual river reach hypothetical upstream modeled test portion overall model.
