1 INTRODUCTION Among the world's rivers, the Yangtze River ranks third in length, fifth in average water discharge at its mouth, and fourth in suspended sediment discharge (Shen et al., 1983). The huge suspended load has created a bar system with heights greater than 10 m below sea level extending over 40 km along each waterway in the Yangtze Estuary (Milliman et al.,1985). Natural evolution of the sand bars has been studied by many scientists and engineers (Prichard, 1967; Ludwig and … 相似文献
