Spatial dimensions	2D
Spatial extent	Watershed-Scale, Reach-Scale
Model domain	Terrestrial, Geodynamic
One-line model description	This is a two-dimensional numerical model that computes the topographic evolution of the facet slope in the footwall of an active normal fault.
Extended model description	The code computes the formation of a hillslope profile above an active normal fault. It represents the hillslope as a set of points with vertical and horizontal (fault-perpendicular) coordinates. Points move due to a prescribed erosion rate (which may vary in time) and due to offset during earthquakes with a specified recurrence interval and slip rate. The model is described and illustrated in the following journal article: Tucker, G. E., S. W. McCoy, A. C. Whittaker, G. P. Roberts, S. T. Lancaster, and R. Phillips (2011), Geomorphic significance of postglacial bedrock scarps on normal-fault footwalls, J. Geophys. Res., 116, F01022, doi: http://dx.doi.org/10.1029/2010JF001861.
