Based on analysis of changes and its impact on navigable conditions of morphology evolution in Zhenyang reach, the proposed idea of the river channel regulation is put forward. The regime changes are mainly reflected in the inlet split ratio adjustment and the mainstream of the local thalweg changes. All of these have led to the river channel conditions have a significant adverse impact. In response to these, proposed idea of channel regulation is put forward. It is to strengthen control of the important beach and coastline which have influence of channel conditions, to stabilize beach slot pattern, to control or adjust the inlet diversion structure, and to maintain the current relatively favorable channel conditions. Especially, for those reaches may be a shallow, it must take necessary engineering measures to narrowed appropriate shallow section and increase the flight capacity tank washing, in order to improve channel scale.
