[1] Results from small-scale and full-scale experiments on avalanche-dam interactions are presented and compared. These experiments were analyzed with respect to the overrun length ( i. e., the distance that the avalanche traveled beyond a catching dam). The differences and similarities in the results are discussed through a cross- comparison of the small- scale experiments and by comparing them with observations from Ryggfonn on avalanche - dam interactions. Further, we establish a simple relationship that appears to be valid for small- scale experiments with granular materials as well as for full- scale avalanche experiments. The relationship relates the overrun length to the speed of the approaching avalanche and the effective height of the catching dam.
