杭州湾灰鳖洋海域海床演变趋势研究

Investigation on seabed evolution of Huibieyang zone in Hangzhou Bay

分析了杭州湾灰鳖洋海域海床的冲淤变化过程,认为该海域基本稳定,呈现东部微冲西部微淤的局面,这一特点是与海域的水动力条件和泥沙沉积特性相一致的,也与海域的岸线变化相吻合。在此基础上依据海域边界条件的变化分析海域的演变趋势。

The paper analyzes the processes of scouring and silting of the seabed. Basically the seabed is stable with slight siltation in the western zone and light deposition in the eastern part. These characters are consistent to hydraulic condition, sedimentation distribution, and the shift of shoreline. Consequently, the trend of the sea bed evolution is analyzed.
