Two-dimensional modelling of the within-field variation in rill and gully geometry and location related to topography

Auteur(s) et Affiliation(s)



Description :
This paper relates the within-field variation in rill erosion rate to topographic attributes and derives a predictive equation between rill erosion rate and topography in a two-dimensional context. The AA. also investigate whether it is possible to delineate the areas prone to rill and ephemeral gully formation based on a topographic threshold condition, and investigate the extent to which the predictions can be improved by introducing the direction of cultivation into the model. To limit the effects of other parameters, a study area of uniform land use and cultivation was used.
