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 [[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:
