Interflow
Interflow
In hydrology, interflow is the lateral movement of water that occurs in the upper part of the unsaturated zone, or vadose zone, that directly enters a stream channel or other body of water without having occurred first as surface runoff (as with throughflow).
Interflow could be described as a 'semi-deep' flow as it is above the regions where baseflow takes place. Interflow is slower than throughflow but faster thangroundwater flow.
Interflow: Water that travels laterally or horizontally through the aeration zone during or immediately after a precipitation event and discharges into a stream or other body of water.
