WebPrecipitation and runoff sculpt the land surface. Each watershed has its own runoff patterns and erosion rates that depend on geology, vegetation, land use and topography. Changes in runoff can increase erosion and sedimentation of the land surface. Excessive runoff can cause downstream flooding and accelerated erosion of the land. Too WebFlooding is a natural phenomenon that occurs when water overflows its banks and spreads onto the surrounding land. Rivers are one of the most susceptible areas to flooding due to their location, topography, and geology. Flooding can cause severe damage to both human life and property, as well as ecological systems.
