Evapotranspiration modules for crop growth simulation. Implementation of the algorithms from Penman, Makkink and Priestley-Taylor
Calculation of evapotranspiration is essential for the estimation of crop water use or for studying the effect of drought stress on crop performance with simulation models. Several methods are available for calculation of evapotranspiration. This report describes three different methods : the Penman method (1948) and the approaches of Makkink (1957) and Priestley -Taylor (1972). The modules described in this report are developed for use in general crop growth models for water-limited conditions, such as in Van Laar et al. (1992). The application of the modules, however, is not limited to the SUCROS type models
