Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 1994-10-01 Abstract A mathematical model for breach growth in sand-dikes and dunes is described. The model is based on the five-step breach erosion process as observed in several laboratory experiments and the Zwin 89 field experiment. 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 test of the model to the data of the Zwin 89 experiment shows good agreement. Finally, a prediction for the growth of the breach width in the Zwin 94 experiment is given.
