Hogback

Also known as
Model type	Single
Model part of larger framework
Note on status model
Date note status model

Incorporated models or components:

Spatial dimensions	1D
Spatial extent	Reach-Scale
Model domain	Terrestrial
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.
