ANALYSIS OF PERMEABLE BREAKWATERS

Hitoshi Murakami, Yoshihiko Hosoi, Yoshitaka Goda

Abstract


This paper discusses the characteristics of hydraulic and water exchange due to the wave action against vertical slit-type breakwaters. The theoretical solution of the reflection and the transmission coefficients for the breakwater models is compared with the experimental results. Furthermore, the water exchange discharge and the water concentration change through the gap of the permeable breakwater are examined experimentally. Finally the most effective geometry of the cross section is suggested for the breakwaters used here.
