Estimating actual evapotranspiration using a detailed agro-hydrological model

摘要: Abstract Actual evapotranspiration (ET) is an important term of the water balance and actual crop transpiration considered to be determining factor in production. However, measurements ET are complicated especially distinction between soil evaporation, which as a non-beneficial loss, requires specific measurement techniques. An attractive alternative use simulation models estimate evaporation. As part comparison different methods ET, physically based model for saturated–unsaturated zone, swap , was used two locations Gediz basin western Turkey. The selected are: field with single (cotton) valley mixed cropping pattern (grapes, cotton, olive trees). well evaporation were simulated taking into account development stage reduction consequences moisture status. For valley, pattern, lumped approach ET. Results presented show that can made method areal
