Dynamic land-use & landscape simulation models for GRASS GIS
LandDyn
A suite of interoperable dynamic geospatial models for GRASS GIS. They include models of surface process change and landscape evolution, agropastoral catchment generation, and landcover change for intensive and shifting cultivation and pastoralism.
The models are written as a series of addon modules for GRASS 6.4. The scripts are maintained at the GRASS Addons repository Subversion server. They can be downloaded individually or as a single compressed tarball. They will operate on all OS platforms supported by GRASS 6.4, and should be compatible with GRASS6.3 on MacOS and Linux. The modules are not guaranteed to work with GRASS7 development branch, but may be compatible.

r.landscape.evol
Simulates the cumulative effect of erosion and deposition on a landscape over time.
The model is written as an addon module for GRASS 6.4 and 7.2. The scripts are maintained at the GRASS Addons repository Subversion server. They can be downloaded individually or as a single compressed tarball. They will operate on all OS platforms supported by GRASS 6.4 and 7.2.

Full MedLanD Modeling Laboratory, version 1
The MML provides a hybrid modeling environment that couples an agent-based model of small-holder agropastoral households and a cellular landscape evolution model that simulates changes in erosion/deposition, soils, and vegetation. The ABM is written in Java and uses DEVS Suite (all needed files are included). The landscape evolution model is written in Python and requires installation of GRASS GIS v.6. Java jar, Java source code, Python source code, and sample data files (as a GRASS spatial database) are available here.
