Abstract:

In China, many large and middle rivers such as Yellow River, Yangtze River, Pearl River, Liaohe River carry a large amount of fine sand into the sea, this results in extensive silt-muddy tidal flats in their estuaries area and connected coastal zone. If the positions of river mouths never change and the condition of sand supply remains the same, the protection of this kind of coast is not a serious problem. However, if the position of river mouth changes or the amount of sediment source reduces, these beaches will suffer strong erosion. For instance, the migration of the Yellow River causes a strong erosion of muddy beach. The authors suggest some major measurements for the erosion control of these beaches, which has been verified by the field experiments at the Jiangsu coast.
