WebJun 8, 2024 · Base flow: To varying degrees, the water in streams has a sustained flow, even during periods of lack of rain. Much of this "base flow" in streams comes from groundwater seeping into the bed and banks of the stream. Soil characteristics: Some soils, such as clays, absorb less water at a slower rate than sandy soils. WebThe geology of an area influences the rate of river erosion. For example, rivers flowing over hard rock have a slower erosion rate as the bedrock is more resistant. However, areas with soft rock are more likely to experience higher rates of erosion. Those landscapes consisting of more resistant rocks are more likely to have steeper valley sides ...
