A new type of breakwater with a step-shaped slit caisson has been developed and some very fascinating results have been found.It was found that this breakwater has low reflection in a wider range of wave fre quency compared to conventional slit-type breakwaters.A numerical analysis which combines the method of matched asymptotic expansions with a boundary element method has been applied for calculation of the reflection coefficients for these structures.However the previous studies were on the condition of non rubble mound.The present paper focuses on the reflection coefficients of the step-shaped slit caisson on the rubble mound in order to apply the step-shaped slit caisson for practical use.
