| Abstract: | The major underwater geomorphological types in the Qinzhou Bay in the Autonomous Region of Guangxi are intertidal shoal , river mouthe bar, tidal ditch , tidal current sand ridage, tidal current deep trough, underwater block door shallow beach and underwater slope according to the data of spot investigation and information analysis. Basic characteristics of the hydraulic dynamic of the river, tide, tidal current and wave are expounded; formation of underwater geomorphological types and its space distribution and sedimental composition are analysed in the paper. Geomorphogic cause of formation and mechanism, tendency of coastal developments are also discussed. |
