Abstract

Mechanism of erosion along a riverbank is full of complexity in nature. Among many forces on the sediment particles along a riverbank, cohesive and viscous forces are predominant. A family of similar particles surrounds every particle and they are bound together under the action of cohesive and viscous forces. In this paper, sediment particles are arranged according to the truncated pyramid model and a general equation for the escape velocity of a particle has been suggested. It is observed that this escape velocity is very much dependent on the inter-particle separation distance for a given liquid bridge volume between a pair of adjacent particles. Determination of the escape velocity is an approach to quantification of volumetric erosion rate. In this paper, a comparison has been made between the values of the escape velocity obtained from a previous study considering only cohesive force and the values of the escape velocity obtained considering both cohesive and viscous forces for a particular liquid bridge volume. All the other parameters remain the same for both the cases. It has been shown that the values of the escape velocity obtained in the present study considering both cohesive and viscous forces increase a considerable amount than the values obtained in the previous study considering cohesive force only for the same input parameters.
