evapotranspiration1948
1948 Geogr. Rev. 38 55 The combined evaporation from the soil surface and transpiration from plants, called ‘evapotranspiration’, represents the transport of water from the earth back to the atmosphere, the reverse of precipitation.
1958 New Biol. 25 52 The hydrologic cycle of an area of land receiving all its water as precipitation can be expressed by the equation P = E + R ± S where P = precipitation, E = evapotranspiration (interception by vegetation, evaporation from the soil and transpiration by plants), R = run-off and S = changes in water storage.
