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. WebCyr et al.
