Incorporated models or components:

Spatial dimensions	2D
Spatial extent	Landscape-Scale, Regional-Scale, Watershed-Scale
Model domain	Terrestrial, Hydrology, Climate
One-line model description	Basin and landscape dynamics
Extended model description	Basin and Landscape Dynamics (Badlands) is a parallel TIN-based landscape evolution model, built to simulate topography development at various space and time scales. The model is presently capable of simulating hillslope processes (linear diffusion), fluvial incision ('modified' SPL: erosion/transport/deposition), spatially and temporally varying geodynamic (horizontal + vertical displacements) and climatic forces which can be used to simulate changes in base level, as well as effects of climate changes or sea-level fluctuations.

Describe processes represented by the model	Basin and Landscape Dynamics (Badlands) is a parallel TIN-based landscape evolution model, built to simulate topography development at various space and time scales. The model is presently capable of simulating hillslope processes (linear diffusion), fluvial incision ('modified' SPL: erosion/transport/deposition), spatially and temporally varying geodynamic (horizontal + vertical displacements) and climatic forces which can be used to simulate changes in base level, as well as effects of climate changes or sea-level fluctuations.
Describe key physical parameters and equations	The model is mainly written in fortran and is based on the following characteristics: - The finite volume approach from Tucker et al. (2001) based on the dual Delaunay-Voronoi framework is used to solve the continuity equation explicitly, - Node ordering is perform efficiently based on the work from Braun & Willett (2013), - A Hilbert Space-Filling Curve method algorithm (Zoltan) is used to partition the TIN-based surface into subdomains, - Drainage network partitioning is generated through METIS library.
Describe length scale and resolution constraints	catchment to continental scale
Describe time scale and resolution constraints	thousands to millions of years
