The model WATER provides feasible computational methods for the determination of temporal and spatial agricultural water consumption. A solution was sought through the creation of a crop‐specific, growth‐stage‐specific soil moisture model. This model, which has been programmed for digital simulation, is a compromise between area‐specific, data‐based regression models and expensive, complex energy‐mass exchange models. It is suitable for evaluating the impact of droughts and other climatic vagaries on crop water requirements. Input scenarios make possible the application of the model to regions where precise data are not available.
