The regional condition of Beizhi reach in the lower reach of the Yangtze River is superior,the development potential is huge,and the channel condition is very important.It is important to master the evolution characteristics of the Beizhi reach,which can provide reference for the synthesized waterway regulation of Beizhi reach.Based on the hydrologic and topographic data of Beizhi reach in recent years,we analyze the river evolution characteristics and evolution tendency.According to the present situation need,we propose the train of thought on waterway regulation of each reach.The result shows that waterway regulation for the Beizhi reach branch shall be implemented on the basis of the existing regime control engineering,and taking the principle of proper utilization according to the water depth.
