Stemflow, canopy drip, and throughfall - Encyclopedia of Earth
In vegetated systems, some precipitation may reach the ground by stemflow, but most often reaches the soil by a process called throughfall.
The "Rutter model" for forest evapo- transpiration, the transport of water into the atmosphere, combines throughfall of rainwater, interception, evaporation and transpiration.
