One-line model description Evolution of a hogback
Extended model description This model evolves a hogback through time. A resistant layer of

rock, which weathers slowly, overlies a softer layer of rock that weathers quickly. Resistant rock produces "blocks" which land on the adjoining hillslope. Boundaries incise at a specified rate. User can set hogback layer thickness, block size, and dip, as well as relative weathering and incision rates. Trackable metrics included are time and space-averaged slope, block height, weathering rate, and erosion rate. Parameters that users need to specify are surrounded by many comment signs.
