古淮口岸线冲淤演变

Scouring-silting Evolution of the Old Huaihe Estuary

根据实地调查资料及有关文献,对古淮河口的动态冲淤演变进行了研究。由于海面变化,黄河夺 淮等诸多自然与人文因素的影响,古淮口海岸线变迁十分复杂。黄河夺淮前,河口东迁缓慢;黄河夺淮后,河口岸线东迁速度加快;黄河北归后,此带岸线蚀退严重。

According to the field investgation and relevant materials, the paper studies the scouring-silting evolution of the old Huaihe estuary. Influenced by many factors such as changes of sea level, the Huanghe River capturing the Huaihe River, changes of the coastline of the old Huaihe Estuary are very complex: It moved eastward slowly before the Huanghe River captured the Huaihe River, the coastline of Huaihe estuary moved eastward with fastspeed: Since the Huaihe River returned northward, the coastline has been scoured seriously.
