Dear all:
In Ecuador there is expected a significant expansion of irrigated areas, where in some cases is essential the inclusion of a drainage system because of the poor drainage of the soil. I have used models like CROPWAT and AQUACROP for estimating crop water requirements. However, now in Ecuador I would like to use a model that allows also the inclusion and simulation of a drainage system. What model would you recommend me? I would appreciate if it is free available. Thanks!
