ParFlow is an open-source, object-oriented, parallel critical zone model developed and maintained at Colorado School of Mines. It includes fully-integrated overland flow, the ability to simulate complex topography, geology and heterogeneity and coupled land-surface processes including the land-energy budget, biogeochemistry and snow (via CLM).


See here for a simulation example.
