  EnvE/ESS 110, Hydrology and Climate  1 1.  Evapotranspiration  Evapotranspiration is a collective term for all the processes by which water in liquid or solid phase at or near  the earth's land surfaces becomes atmospheric water vapor.  The term includes both evaporation (from  rivers, lakes, bare soil, and vegetative surfaces) and sublimation (from ice or snow fields).  Globally, about 62%  of the precipitation that falls on the continents is evapotranspired.  Of this, about 97% is evapotranspiration  from land surfaces and 3% open-water evaporation.  Evapotranspiration exceeds runoff in most of the river  basins on earth.    The following is a mass balance approach for determining the total volume of water that is being evaporated,  vol E , within a catchment area,    ()( ) vol in in vol out out vol vol in in out out V WSWGW ESWGW V E W SW GW SW GW V ?=? ++ ?+ + =? =++ ? ? ??
