| Abstract: | The characters of outer bar and inner stream reach in the Yangtze river estuary are presented by analysis of streambed evolution. Based on the value and distribution of flow velocity in construction stage by 2D hydrodynamic model, the failure mechanism of beach and bank protection works is studied from hydrodynamic, construction and streambed evolution. At last, the stratagies of beach protection and accretion promotion in construction and plan layout of groin and longitudinal dam are presented. |

| Keywords: | the Yangtze river estuary outer bar and inner stream beach and bank protection bed development hydrodynamic model |
