Resumen

The set-up and preliminary results of a series of model investigations on dune breaching is presented. Based on these 2DV-tests the insight into the processes related to the lowering of the crown of a sandy dam during overflow conditions has been enlarged significantly. Although dam erosion is mainly due to transport processes on the inner slope, the angle of the outer upstream slope showed to be very important also. Coarser sand results in larger erosion rates, whereas the effect of packing is only minor.
