Description :
The AA. attempt to explore such an interaction on the assumption that the sediment transport is only caused by a surface process like slope wash. This paper describes the working hypotheses and the organisation of a deterministic-stochastic computer program model, together with a sensitivity analysis performed during parameter optimisation by a trial and error process. This model may then be used to investigate several questions concerning the geoecology of these features such as the role of geomorphic processes and vegetation behaviour, whether they represent a steady-state or an aggradation or degradation succession and their efficiency as soil stabilisation.
