This article is based on an unpublished manuscript by the late Prof.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. Characteristic Es-values exist for
these processes. Also, Es-values vary in regions with differing pedo-botanical characteristics and
land-use. The difference between Es-values for single storm events and longer periods are related
to the magnitude-frequency distribution of erosive activities and allow in many cases an
assessment of the age of erosion phenomena and an estimation of the recurrence period of extreme
single events.
