Studies on Breakwater of Slit-type Structures

Abstract

The analysis of the reflection coefficients and the transmission coefficients on slit-type structures is very important for the design of breakwater. In the last paper we reported the results of some measurements on vertical square piles. This time we tried a few experiments using the vertical circular piles in order to research the flow characteristics of slit-type structures. The strongest relation is observed between transmission coefficient and wave steepness as well as on the square piles. Therefore, this paper discribes the analysis of transmission coefficients with the theory of small amplitude waves. Based upon the results of the experiments, a computation formula of transmission coefficients has been prepared. The experimental data of transmission coefficients almost coincide with the theoretical curve.
