Calculation and Analysis on Water Flow Character of Dongbei Waterway in Middle Reaches of Yangtze River

Abstract:

Dongbei waterway in the lower reach of Yangtze River includes three waterways: Hukou waterway, Heng waterway and Zhi waterway. For a long time the documents about the evolution of measured data in based mainly on topographic information and it is insufficient materials actually measured about the character of water flow. In order to make up the incomplete measured documents, it is intended herein to make calculation of character of water flow by means of mathematic model. The results show that, there are overflows to various extents for the side shoal at Sizhouwei under different discharge. It appears crossing troughs in the left to the side shoal at Sizhouwei. The bigger flow velocity of lower shoal and its left rim is possible for being washed out.
