Hogback [edit]

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.

Describe time scale and resolution constraints
Describe any numerical limitations and issues	Model works well for resistant layer dips between 10 and 80 degrees. End members will work, but domain setup must be altered.
