摘要
本文通过伶仃洋、黄茅海的地貌形态特征和动力特性分析,认为这两处的淤积模式基本上与一般河流水库的淤进型模式近似,并引用Lapshenkov公式预测它们接近淤满时的年限约700年。
The lingdingyang and Huangmaohai estuaries located separately at the east and west of the Zhujiang Delta, are the remain parts of the paleo—Zhujiang estuary in the evolution process of the delta. Both of them have the shape of the bell with underwater landform of 'two channels and three shallows'. Although different in time and space, they can be categorized as a transition between the estuary of strong tide and that of runoff-dominated delta. The sedimentation model is basically similar to that of reserviors in rivers. Applying Lapshenkov formula which is used for calculating reservior sedimentation, it is predicted that the estuaries will be silted up in about 700 years.
