Answer Details
The intensity of erosion by a river is determined by the volume of water, gradient of the valley, and the load carried.
Erosion by a river refers to the process of wearing away the river's bed and banks over time. The intensity of this erosion is influenced by several factors, including the volume of water flowing in the river, the gradient of the valley through which the river flows, and the load carried by the river.
The volume of water flowing in the river determines the amount of energy available for erosion, with higher volumes of water carrying more energy and therefore causing more erosion. The gradient of the valley, or the slope of the land through which the river flows, also influences erosion by affecting the speed of the water flow. Steeper gradients generally lead to faster flow rates and more erosion.
The load carried by the river refers to the amount of sediment and other materials that the river is carrying along with it. This load can range from small particles like silt and clay to larger rocks and boulders. The load carried by the river can significantly affect its erosive power, as heavier loads can cause more friction and turbulence in the water, leading to increased erosion.
Overall, the intensity of erosion by a river is determined by a combination of these factors, including the volume of water, gradient of the valley, and load carried by the river.
