To exert all the strength of Changjiang River's transport ability, the renovation of Doulizi shoal should be done as soon as possible. The thesis analyzes the riverbed evolvement of Doulizi shoal based on the relief maps measured before and finds the reasons of the evolvement. Then we find the rule of the riverbed evolvement. And it will effect on the optimization of Doulizi renovation project. |
