连云港赣榆港区水下地形地貌研究
|
摘要
通过对连云港赣榆港区水下地形测量工作,结合以往采集数据分析,阐明了赣榆港区的水下地形变化趋势及周围地貌特征。研究区海底地形总体呈东—东南倾斜的趋势,地形变化较缓,以赣榆港航道为界,南部从柘汪河到龙王河口等深线较平直,由陆向海呈阶梯状分布,水深从0m一直缓慢加深至-10m,平均坡度<1‰,近岸主要为沙泥滩,泥滩位于龙王河口以南,受河流及沿岸细粒物质大量补给和潮流作用为主的海洋动力控制,淤积作用显著。
The paper aims to study the underwater topography in Ganyu Dockland,Lianyungang City.With the help of previously collected data,it expounds the changing trend of underwater topography and its nearby characteristics.The results show that the inclination of underwater topography is from east to southeast.The topography changes slowly and the depth of water is deepened slowly from the shore to the sea.There are mainly two kinds of coast types in the study area:the sandy beach,the sand and silt beach.Divided by the harbor approach of the Ganyu Dockland,depth contours ranging from Zhewang River to the mouth of Longwang River in the south are relatively straight,extending in ladder pattern from land to sea.The water depth slowly goes from 0 mto-10 m,with average slope less than 1‰.Located to the south of the mouth of Longwang River,the offshore sand and silty beach is severely deposited because of the great supply of fine materials in and along the river and the effect of tidal action.
