Physically-Based Distributed Hydrological Model

GEOtop 2.x/3.x is a distributed model of the mass and energy balance of the hydrological cycle. GEOtop is applicable to simulations in continuum in small or relatively large mountain catchments. GEOtop deals with the effects of topography on the interaction between energy balance (evapotranspiration, heat transfer) and hydrological cycle (water, glacier and snow).
