Abstract
The riverbank erosion is quite a common phenomenon with a high degree of complexity. Here, ‘Truncated Pyramid Model’ for the particle arrangement has been used considering hydrostatic force, pore pressure force, cohesive force and gravitational force acting on the particle. Three different degrees of exposure (fully exposed, half-exposed and fully submerged) have been investigated with three different particle sizes (0.3, 0.4 and 0.5 mm radius) for both the cases of rising and falling water level. Conservation of angular momentum theorem has been applied in microscopic level to determine the particle escape velocity and the variation of the same with the inter-particle distance and water content for different sizes of the particle. The escape velocity is the significant parameter to find the rate of erosion. Also, it has been found that the particle is in a more vulnerable situation when the river water level starts dropping.
