The steepness of a river, or its gradient, directly influences the rate of erosion along its banks and riverbed. A steeper river typically has a faster flow velocity, which increases the energy of the water. This higher energy allows the river to transport larger sediment particles and exert more force on the surrounding rocks and soil, leading to more significant erosion. Conversely, in flatter areas, the flow velocity decreases, resulting in reduced erosive power and a lower rate of erosion. Thus, steeper river gradients generally correlate with higher rates of erosion.
