Abstract: In the study, the optimization approach is applied to find the optimal lateral outflow hydrograph to control hazardous flood water stages in open channel and channel network in a watershed. By using the internal boundary conditions of the adjoint equations in each confluence of a channel network, the adjoint sensitivity analysis is successfully applied to obtain the optimal solutions of the outflow hydrographs at floodgates. The hypothetical flood control examples demonstrated the applicability and the accuracy of the optimal control methodology to solve the optimal hydrographs of the lateral outflow for control of flood diversion in a channel network and a natural river. In addition, this optimization model based on the nonlinear Saint-Venent equations has been integrated into a general flow model, called CCHE1D, which has been systematically verified and validated. Therefore, this optimization tool is capable of solving realistic flood control problems in natural streams and watersheds.
