Side erosion of the levee along the curved portion of the river and the consequent levee destruction are phenomena of great importance for river planning. Previous research works on this problem from hydraulic point of view are limited to the water flow, and there is almost no work which deals with it in the way relating the fluctuating fluid force and erosion mechanism. The present study aims to provide a breakthrough in this situation. It is considered that side erosion occurs by the destruction of the bindings between the materials constituting the levee due to the action of fluctuating fluid force of river flow. In this paper, the process is modelled through mechanical consideration and the direction of the treatment of experimental data is proposed. Also, the first step condition is given for the destruction of the levee as the consequence of this mechanism.
