Abstract

A mathematical model for breach growth in sand-dikes and dunes is presented. The model is based on the five-step breach erosion process as observed in several laboratory and field experiments. A simplified Galappatti (1983) pick up mechanism for sand from the bed is combined with Bagnold's (1963) modified (Visser, 1988) energetics-based sand transport conception to describe the breach erosion. The comparison of the model predictions with the data of the Zwin 89 field experiment shows good agreement.
