This last 2014 EGU we were invited to talk at HS2.1.2 session: Advances in Integrated Process-Based Distributed Hydrologic Modeling organised by Matteo Camporese and co-conveners. Giacomo Bertoldi (GS) gave it, and talked mostly about his own research on echohydrology of alpine catchments. His presentation shows very well his recent work and exploits the capabilities of GEOtop that were not presented at AGU last Fall. You can enjoy his presentation here.
His own collaborator, Johannes Brenner, completed the view with a second presentation that can be found here.
