The major component in fluvial dynamics is bank erosion, which has a significant impact on a variety of physical, ecological, and socioeconomic issues. Some lateral dynamics associated with bank erosion have been significantly known to exhibit positive influences on riparian vegetation succession, the formation and evolution of river and floodplain morphology, and the production of dynamic habitats important for aquatic and riparian species. It is also well known that bank retreat is the result of three processes interacting with one another (erosion processes, and mass wasting). In response to downstream changes in energy circumstances, bank material, and climate, our findings imply the presence of shifting bank process dominance over a hypothetical drainage basin. It is also well known that bank retreat is the result of three processes interacting with one another (erosion processes, and mass wasting). Bulk failure may also arise after the river has been drawn down (for example, after a river flood); water saturates the soil, causing the pore water pressure at the slip surface to rise, reducing the restraining friction along the slip line. The increase in soil weight caused by the additional underground water aids movement. The slippage of bank is predicted to be prevalent in all estuaries with sloping sidewalls. Some rivers of that type, on the other extreme, are generally immune to bank slipping for at least three ways.

Some rivers with stable banks have a healthy level of erosion; nevertheless, unstable rivers and the erosion occurring on their banks are a reason for concern. The most important cause of river bank erosion is deforestation, gravel mining, dam and bridge building, artificial cutoffs, bank revetment, and land use changes influence stream shape flooding. Flooding is more likely during the wet season. During a flood, a large volume of water moving at a high velocity has enough energy to rip the top layers of soil away or possibly induce catastrophic collapse. Strong and severe rainfall can degrade top soil. Strong vibrations caused by heavy rains can destabilize and deteriorate non-cohesive bed components. Sedimentation can be driven by a range of environmental phenomena. As the river's banks get saturated, silt deposition limits the river's water holding capacity. As a result, the water's course has been altered. Because of the volume of water moving or the high stream gradient, a strong current form. River bank erosion can occur if river currents are quite strong. Anthropogenic activities such as deforestation, gravel mining, dam and bridge building, artificial cutoffs, bank revetment, and land use changes influence stream shape and ecological patterns. Natural occurrences are weaker than anthropogenic activities when it comes to modifying stream patterns
