<Ul> <Li> Interflow is water that infiltrates the soil and then moves laterally to the stream channel in the zone above the water table . Much of this water is transmitted within the soil itself, some of it moving within the horizons . Next to baseflow, it is the most important source of discharge for streams in forested lands . Overland flow in heavily forested areas makes negligible contributions to streamflow . </Li> </Ul> <Li> Interflow is water that infiltrates the soil and then moves laterally to the stream channel in the zone above the water table .

Overland flow is a stormwater runoff that begins as thin layer of water that moves very slowly (typically less than 0.25 feet per second) over the ground . Under intensive rainfall and in the absence of barriers such as rough ground, vegetation, and absorbing soil, it can mount up, rapidly reaching stream channels in minutes and causing sudden rises in discharge . The quickest response times between rainfall and streamflow occur in urbanized areas where yard drains, street gutters, and storm sewers collect overland flow and route it to streams straightaway . Runoff velocities in storm sewer piper can reach 10 to 15 feet per second . </Li> </Ul> <Li> In dry regions, cultivated, and urbanized areas, overland flow or surface runoff is usually a major source of streamflow .
