Acquiring sufficient knowledge about soil structure of the river side wall and arrangement quality of its layers will be helpful to prevent soil erosion and distraction. The main purpose of this research is to find a proper way to decrees effects of river bank erosion with regard to studying the effects of clay on the rate of the river bank erosion. To conduct the research, some experiments have been performed by using an experimental model with 14m length, 90cm width, and 50cm depth. The results demonstrate the major role of clay in decreasing the rate of side wall erosion and the depth of scour. In the final analysis, the research comes to this conclusion that there is an inverse relationship between the increasing percentage of clay and the side wall erosion rate and scour depth. By increasing the amount of clay materials, adhesives, wall scour depth profiles, the declining trend is involved. So that the figure in clay materials 7/5% to almost zero. Scour depth at the top of the wall to increase the adhesion of materials resulting from the addition of bentonite clay to 7/5%, compared to non-clay materials has decreased by about 97% And at the beginning of the clay wall materials 7/5% of the action occurring is very low.
