Evapotranspiration rate for malawi
Webequation based on water balance data from Malawi that can explain interannual variation in evapotranspiration. Although the functional forms of the Budyko [1958] and Pike [1964] ... higher evapotranspiration rate than the pasture, and the dif- ference was attributed to the ability of the trees to access soil moisture from greater depth. Calder ... WebEvapotranspiration, the mass flux of water associated with the latent heat flux, can be expressed as ET = l E / ( l r w) (12) where ET is the rate of evapotranspiration (length per time). Substituting equation 11 into equation 12, ET can be expressed as Ea / ( l r w ) { g c [ ( Tl - Tu ) / ( el - eu )] + 1} (13) Knowing or assuming that:
