THE INFLUENCE OF BREAKER TYPE ON RIPRAP STABILITY

John P. Ahrens

Abstract


Test data related to the stability of dumped quarry stone riprap under wave action is presented The tests were conducted in the large 635-foot wave tank at the Coastal Engineering Research Center at near prototype scale The data indicate that the stability of the riprap is strongly influenced by the type of breaker The lowest riprap stability is associated with a breaker type intermediate between plunging and surging, sometimes referred to as a collapsing breaker.
