Detailed explanation-3: -Riverbank erosion is one of the major and unpredictable problems worldwide [1] which occurs both naturally and through human impact. The erosion involves the wearing away of soil found along the river bed and banks that will lead to the accumulation of sediment which in turn will increase the river pollution problem.

Detailed explanation-4: -River-bank erosion creates land loss at a large scale. Several hectares of land, including homesteads, fertile lands, and mango gardens/orchards, are washed away by the river due to river-bank erosion. In the gram panchayats such as Gopalpur, Dharampur, Hiranandapur, some people have lost more than half of their land.
