Abstract

A particle on a riverbank is subjected to a number of forces. Among them, cohesive and viscous forces are predominant, hi this present work, an analytical model called the Truncated Pyramid Model has been used to quantify the effect of the viscous force on the particles on a riverbank and the dynamic influence of water entrapped between the particles. For this, the existing model has been suitably modified to incorporate the viscous effect. The whole mechanism involves a good number of variables namely inter-particle distance, separation speed, liquid bridge volume, radius of the sphere particle and radius of the wetted area. In this work, cohesive and viscous force components have been resolved along horizontal and vertical directions and two separate differential equations have been established for horizontal and vertical components of separation speed that is varying with time. Variation of separation speed with separation distance for a particular liquid bridge volume at different times has been evaluated thereafter.
