Abstract: Low-lying cities are usually built along rivers with greater risk of flooding, it is urgent to carry out research on improving flood control capacity. In this paper, taking Jintang County of Chengdu City, Sichuan Province as an example, a 1D-2D coupled hydrodynamic model was established to simulate flood inundation and evaluate the flood control effects of different engineering measures, including river regulation and flood diversion. The water level in the urban area could be reduced by 0.62~2.43m, urban inundated area decreased by 30%, and the urban flood control capacity improved effectively.
