Study on the Shoal and Trough Evolution and the Navigation Conditions of Wandering Reaches of the Hanjiang River

This paper studies the erosion and deposition in the lower reaches of the Hanjiang River and their influences on the navigation after the building of the Danjiang-kou Reservoir. By analysing hydrological and topographic data, the characteristics of shoal and trough evolution of the wandering reaches on the Hanjiang River have been investigated. The navigator conditions have been comprehensively considered and some useful conclusions to navigation are obtained.
