evapotranspiration
This process is called evapotranspiration.
The potential evapotranspiration concept was first introduced in the late 1940s and 50s by Penman and it is defined as " the amount of water transpired in a given time by a short green crop , completely shading the ground , of uniform height and with adequate water status in the soil profile ". Note that in the definition of potential evapotranspiration , the evapotranspiration rate is not related to a specific crop .

EVAPOTRANSPIRATION
Evapotranspiration refers to the combined process of water surface evaporation, soil moisture evaporation, and plant transpiration. It is significant during a storm because the stormwater from evapotranspiration is a water budget component for wetlands, wet ponds, and other stormwater treatment practices.
