Based on the analysis of the fluvial process and characteristics of the shallow area of Quangang waterway in the Ganjiang river, this paper carries out a model experiment for determining the waterway regulation scheme for the lower shallower area Quangang. After implementation of the engineering during 2005—2007, the shallow area disappeared and the waterway condition was improved obviously: The waterway not only reaches the present maintenance dimensions, but also satisfies the construction standard stipulated in the development planning of the waterway.
