Waterway Regulation Effect of the Letianxi Reach between the Three Gorges Project and Gezhouba Project

摘要

It is the first implementing waterway navigation project between the Three Gorges Project (TGP) and The Gezhouba Project. Based on analyzing of the navigation-obstructing characteristics, waterway regulation ideas and schemes are put forward. A three-dimensional flow mathematical model is used to simulate the change of water level, flow velocity, flow pattern. And the effect of the regulation project is analyzed and contrasted with and without it. At last, the reasonable regulation scheme is proposed.
