EXPERIMENTAL STUDY ON STABILITY OF NEW WAVE DISSIPATING BLOCK FOR SLOPING BREAKWATER

Abstract

 Two new types of wave dissipating blocks are examined in hydraulic experiments to investigate the stability of sloping breakwaters. Improved stability number formulae were proposed from the experimental results. The experimental results were compared with TETRAPOD cases. One of the target blocks which has radiation shape same as TETRAPOD had about 1.4 times higher stability. Another new type block which is multiple legged shape with an exis had about 1.5 times higher stability. Relatively high performance of the new type blocks were demonstrated and analysed.
