Operation Dispatching Feature Analysis Based on TELEMAC-2D

China is in the stage of rapid urbanization, resulting more and serious urban waterlogging problems. Based on TELEMAC-2D hydrodynamic model, this paper conducted mathematical modeling Swan Lake flood storage detention area Dongying City, simulated inflow inundation process under three rainfall scenarios typhoon “Rumbia”, “Lekima” 50-year return period. The simulation results show that when water intakes are opened at same time (Plan A), total amount period scenario not exceeding capacity, respectively. When only one intake was B), incoming flow capacity area. In all setting plans scenarios, maximum level before sluice 3.42m. By operating dispatching Lake, Guangli River can be effectively controlled below 3.5m, ensure drainage system supported by top maintain normal function. 1#, 2# 3# design corresponding intake, provide a scientific basis for operation regulation control
