Abstract
The core section of Guiyang Nanming River suffers from river water quality deterioration, black turbidity, sediment deposition and other phenomena. The deposition is extremely serious particularly at the upstream area in front of the flap dam. It is necessary to upgrade and transform the flap dam, thereby preventing the sedimentation in the front of the dam, and improving the ecological environment of the river. The flap dam should be newly designed, and its application should be studied.
