  • An erosion limited slope evolution model is proposed as a generalisation for both flux (transport) limited and supply (weathering) limited conditions, which appear as extreme special cases. Distinctions can be made between rainsplash, rainflow
  • and rillwash, and there is scope for forecasting the evolution of an armour layer with grain size selectivity. The model has been implemented in finite difference form. Five model runs are shown as illustrations of the scope of the erosion limited approach.
  • Ahnert's process-response models of denudation and the scale dependence of sediment yield models. An attempted reconciliation

  • mass balance of Ahnert is similar in more respects to the sediment budget formulation used in the Canadian work. The essential difference in the two approaches is the way in which storage is handled in the two models: Ahnert focusses on regolith

  • badlands the latter operation yields a minimal age between 2,700 and 40,000 years which dates badlands in this belt back eventually to Upper Pleistocene times. Therefore, this application of the Es model is offered as a contribution to the still ongoing
