Quantity of water entrapped between sediment particles imparts strength up to a limit and increases the stability of a riverbank. In the present study, this strength of the sediments has been investigated in terms of escape velocity of the sediments. Escape velocity has a considerable impact on the stability of the bank surface. Here, the “Truncated Pyramid Model (TPM)” for arrangement of the sediments has been utilized to determine escape velocity for different wetted surface conditions and inter-granular spaces. It has been found from the present investigation that irrespective of the variability in the riverbank morphology, the escape velocity attains a large value due to enhancement of the wetted surface area resulting in riverbank stability.
