Throughflow

From Wikipedia, the free encyclopedia

In hydrology, throughflow, a subcomponent of interflow, is the lateral unsaturated flow of water in the soil zone, where a highly permeable geologic unit overlays a less permeable geologic unit, and which returns to the surface, as return flow, prior to entering a stream or groundwater.[1][2] Once water infiltrates into the soil, it is still affected by gravity and either infiltrates to the water table or travels downslope.[1] Throughflow usually occurs during peak hydrologic events, and flow rates are dependent on the hydraulic conductivity of the geologic medium.[1]
