【Abstract】 The Jianlin Sedimentary Bar, which is our study area, is located in the modern Yellow River Delta. Nearly 50 sedimentary samples were collected from the bar and the river bed. The components of grain size of the samples were analyzed with sieving and Stoke’s method. The grain size distribution and their relative parameters suggested that the movement of the Yellow River water is the same as the movement of water with low content suspended matter. Dynamic characteristics analyses also supported this opinion. Furthermore, the principle of sedimentation of the Yellow River is also discussed.更多还原
