象山港属基岩海岸潮汐汊道,而其物质供应以细粒沉积物为主.本文探讨了象山港沉积物分布和悬沙搬运特征,并以潮交换过程、汊道地形、时间-流速不对称和悬沙沉降性质的综合作用解释其成因.虽然象山港落潮流占优势,但由于潮交换作用,净输沙方向仍指向湾内,导致纳潮海湾的缓慢淤积.另方面,随潮交换过程输向湾内的粉砂相对较少,从而造成湾内、外的沉积分异.
Xiangshan Port belongs to the tidal channel of bedrock coast, and its material supply mainly consists of fine-grained sediments. In this paper, the sediment distribution and suspended sediment transport characteristics in Xiangshan Harbor are discussed. The tidal channel, tidal channel, time- Symmetry and sedimentation of the nature of the sediment explain the causes of formation.Although Xiangshan tidal current trend dominant, but due to the tide exchange, the net sand transport direction still point to the bay, resulting in the slow deposition of the tide bay .On the other hand, with the tide exchange process Less silt is transported to the bay, causing differences in sedimentation both inside and outside the bay.
