RillGrow 1 Soil Erosion Model


RillGrow 1 was the first, very simple, attempt at constructing a model for rill initiation and development using these concepts. It uses data on initial microtopography to generate realistic rill patterns; however, it does not operate within a true time domain.

The model and some results are described in Favis-Mortlock (1996; 1998) and Favis-Mortlock et al. (1998a), and in a poster paper which is available here.
