A small-scale field check on the Fisher-Lehmann and Bakker-Le Heux cliff degradation models

Auteur :
HUTCHINSON, J.N.

Description :
The paper considers the development of initially staight, steep rock cliffs, bounded above and below by horizontal surfaces, in which basal debris removal is zero and degradation occurs by te weathering away of fine debris from the cliff face to form a scree at its foot. Of the slope degradation models available, the two earliest and simplest, namely the Fisher-Lehmann and the Bakker-Le Heux models, are regarded as most relevant and are briefly summarized. The main purpose of this paper is to check the predictions of these models, particularly with regard to the shape of the rock surface buried beneath the scree, against field data.
