Experimental study on the interaction between the hydraulic transport of failed bank soil and near-bank bed evolution

Shui kexue jinzhan, 2014
Bank failure is a typical process of lateral channel migration. As a huge sediment source,failed bank soil may directly cause the increase of sediment concentration and considerable channel evolution in a short time.
