Decision support systems for the benefit of stakeholders have to be strengthened by relying on biophysically based modeling platform that encompass the aforementioned compartments and the related water flows. This requires first parameterizing and calibrating the modeling platform components, where the use of remote sensing if of prime interest for constraining models in a spatially distributed manner, and
