Abstract:
This paper introduces some resarch results on sediment model experiment of navigation in the course of construction. including the laws of erosion and deposit change of sediment in dam area,depositional configuration of sediment in the approaches of temporal ship lock, distribution and surface sea-level of deposition,speed of return deposition, volume of deposition of frustrating navigation, grain grade of deposition and the effect of deposition on navigable condition in open channel and temporal ship lock and so on. Some measures of amelioration are presented,which have important value to the construction of the project.
