Abstract
In this paper,the scouring and silting characteristics of the northern coastal waters of Binzhou are discussed upon the measured data for surface sediments and water depth,with the help of sedimentation velocity formula for numerical simulation of tidal current field.The results show that from 1983 to 2001,erosion happened mainly in the area shallower than 4m,the amount of erosion is about 0.2 m in average and the area with largest erosions appears in the estuary of the Taoer River and the area on the west side of the estuary,while the east of the estuary is under siltation.Siltation is obvious in the area outside the 4m isobaths and the total amount of deposition is about 0.3 m.The vol ume of siltation tends to increase as the water depth increases.From 2001 to 2016,the area within the 0m isobath is mainly under siltation,with the strong siltation area near the Majia River estuary in the west side of the Binzhou harbor breakwater.The area between 0～4 m isobath is mainly under erosion,and the average amount of erosion is about 0.6m.The area outside of the 4m isobath is mainly in a slight siltation state,and the erosion occurs only in the area near the embankment of the Binzhou Port.The influence of port engineering is suspected the major factor in controlling the scouring and silting regimes in the study area.关键词
