	The objective of this project is to study the effects of 3D fault slip on landscape evolution. Specifically, there can be implications for the steepness of rivers and the evolution of drainage network patterns when considering the full 3D solution for fault slip. Our method is to apply kinematic conditions to points on a model landscape surface, representing tectonic motion, and allow for surface processes to erode the surface. Additionally we include rock damage associated with shear strain as an influence on rock erodibility surrounding the fault. Results suggest that the lateral motion attributed to slip along a fault plane can drastically increase channel slope in reverse thrust regimes and decrease slope in normal rift regimes, however, this depends on the dip angle of the primary slip surface.
