Overtopping for rubble mound breakwater armoured with the new BLOCK- RAKUNA-IV

Tóm tắt

    The paper presents the physic model test results on wave flume about the ability of overtopping reduction of new amour unit-Rakuna IV through roughness factor γr. The results from 58 tests for Rakuna IV and Tetrapod showed that the wave overtopping reduction factor of this armour unit is not a constant but depends upon the breaker indexm1,0.
