ABSTRACT
ABSTRACT: Impulse waves are counted to the most dangerous natural hazards, because of the large masses of slide material involved, the huge waves triggered on large water bodies and their tremendous devastation potential. A spectacular and destructive impulse wave in relation to hydropower installations occurred on October 9, 1963 in North-eastern Italy. Since this incident, dam safety has become a global issue and all major dams have to be assessed against such phenomena.
