In jiangxi province, china, a new river will be excavated in the southern part of Qinglan Lake to drainage the main flow of Fuhe River into the Lake to improve the local flood prevention and navigation problems. A physic model is established to analyze the changes of flow characteristics under different engineering schemes. The research shows that water level decreases 1.91m, flow velocity of the upstream increases to 4.83 m/s, under P=5% River flood, which means the diversion engineering can significantly relieve the local flood pressure, but increase the scouring risks of wading buildings such as piers and embankments. Then the further optimization study shows that scheme 3 not only reduced the engineering quantity, but also decreased velocity increase rate from 61% to 48%.
