The work of Concetta D’Amato Ph.D. started with joining together a reasonable evapotranspiration model with a solid infiltration model building a virtual lysimeter.
The basic is to have the two models to connect, and we, in GEOframe, have them, due to the work of Michele Bottazzi and Niccolò Tubini. The first built Prospero, the GEOframe component that use a novel formulation of the Penman-Monteith solution for evapotranspiration, the second designed and coded a Richardz 1D solver based on a novel algorithm.
Obviously attaching the two models was not as easy as it can be thought, since the goal was to have a coupled system in which transpiration depends on water content and water content depends on transpiration with feedbacks among the few systems. The presentation illustrate how the coupling works and some simulations. At present the simulations are virtual reality, meaning that they are not parametrized according to some real case, but we hope to find appropriate data in the Watzon project. The figure, under which, by clicking you’ll find Concetta’s presentation, illustrates the directions her research can take in the following years. One goal was to do better than Hydrus 1D, being more reliable, more robust, more flexible, multiplatform and open source. Maybe we already accomplished it :-) ?
