DetachmentLtdErosion


Metadata

Also known as
Model type Single
Model part of larger framework LandLab
Note on status model
Date note status model
Incorporated models or components:
Spatial dimensions 2D
Spatial extent Landscape-Scale, Regional-Scale, Watershed-Scale
Model domain Terrestrial
One-line model description Simulate detachment limited sediment transport.
Extended model description Landlab component that simulates detachment limited sediment transport is more general than the stream power component. Doesn't require the upstream node order, links to flow receiver and flow receiver fields. Instead, takes in the discharge values on NODES calculated by the OverlandFlow class and erodes the landscape in response to the output discharge.

As of right now, this component relies on the OverlandFlow component for stability. There are no stability criteria implemented in this class. To ensure model stability, use StreamPowerEroder or FastscapeEroder components instead.
