    River bank failure Wikipedia

    River bank failure can be caused when the gravitational forces acting on a bank exceed the forces which hold the sediment together failure depends on sediment type, layering, and moisture content all river banks experience erosion, but failure is dependent on the location and the rate at which erosion is occurring river bank failure may be caused by house placement, water saturation
