Abstract: According to the characteristics of the shoal and rapids lying in Changtan reach in Mingjiang river and obstructing the navigation channel, a model test was conducted to study the regulation schemes and took good effects. In the paper, the model design, verification and testing process of the Changtan reach engineering are introduced in brief. The project has been already accomplished. By several hydrographic years, verification, the navigation conditions have been greatly improved, and the regu
