Abstract: The East Qinhuai River is a new floodway built at the lower reaches of the Qinhuai River basin, which helps tackle the peak flood discharge problem of the Qinhuai River. We established a coupled hydrology-hydrodynamics model of the Qinhuai River basin and the East Qinhuai River using MIKE11 software, and then conducted a quantitative analysis on the feasibility and flood control benefit of the engineering dispatching solutions, such as lowering water levels prior to rainfall, control of Wudingmen sluice gate and single-way flood discharge by the East Qinhuai river project. The results showed that lowering the water levels prior to rainfall has little effects on flood control; when operation of Wudingmen sluice gate should take into account the upstream and downstream flood discharge; single-way flood discharge scheme by the East Qinhuai River is effect for low rainfall in the basin.
