Note on status model
Date note status model

Incorporated models or components:

Spatial dimensions	2D
Spatial extent	Landscape-Scale, Watershed-Scale
Model domain	Terrestrial
One-line model description	Exponential soil production function in the style of Ahnert (1976)
Extended model description	This component implements exponential weathering of bedrock on hillslopes. Uses exponential soil production function in the style of Ahnert (1976). Consider that w_0 is the maximum soil production rate and that d* is the characteristic soil production depth. The soil production rate w is given as a function of the soil depth d, w = w_0^(-d/d*) The ExponentialWeatherer only calculates soil production at core nodes.

Keywords:	hillslope, weathering, soil production,
