This article is based on an unpublished manuscript by the late Prof. Dr. Jan De Ploey. It focusses on the erosional susceptibility of catchments in terms of total energy input by the meteorological factors water and wind (Es-model). The form
and the universal character of the basic expression of the erosional susceptibility are explained. Applications of the model are illustrated for different processes such as landsliding and debris flows, gullying, creep, and rill-interrill combinations.
