[[Image:|300px|right|link=File:]]As part of the Mediterranean Landscape Dynamics (MedLand) project to create a modeling laboratory for human-landscape interaction, we have developed a suite of landscape evolution tools in the GRASS GIS environment. The core of this tool set is a Python script to estimate sediment transport for hillslopes, gullies/rills, and small channels, and simulate resulting terrain change for high-resolution 3D digital landscapes. Because it takes advantage of raster-optimized routines in GRASS, it is very fast on normal desktop systems, making it ideal for simulating long-term landscape change resulting from human activity, climate change, or other drivers. We provide examples of how this landscape evolution model is being used in the MedLand project.
