tRIBS (TIN-based Real-Time Integrated Basin Simulator) is a fully distributed physically-based hydrologic model developed by the Bras Group at the Massachusetts Institute of Technology (Ivanov et al., 2004). A Vegetation Generator for Interactive Evolution (VEGGIE) model was coupled with tRIBS. tRIBS+VEGGIE (Ivanov et al., 2008a,b; Sivandran and Bras, 2012; Lepore et al. 2013) explicitly accounts for the spatial variability in precipitation fields, vegetation, soil moisture and topography to simulate different components of the hydrological cycle. The model is capable of a sophisticated description of several ecohydrological processes including plant physiology and spatial dynamics over the complex topography of a river basin. It uses voronoi polygons as basic computational units. More recently, a geomorphic module was developed within tRIBS to model sedimentation mechanisms by simulating main hillslope and channel erosive processes (Francipane et al., 2013). Landscape evolution feedbacks to hydrological dynamics through local changes of slope, aspect, and drainage network configuration.
