Abstract

Gravity-type breakwaters such as the rubble mound type are ineffective in intermediate-depth
and deep waters due to high construction costs. In intermediate-depth and deep waters, the skirt-type
breakwater is one of the best alternatives due to the low construction cost because the breakwater structure is
consists of a pile at the bottom part and a skirt wall in the upper part of the structure. To assess the effectiveness
of the skirt type breakwaters, two-dimensional physical modeling conducted on the wave flume in Ocean
Engineering Laboratory at Bandung Institute of Technology, Indonesia. In this study, a Single Chamber Skirt
Breakwater (SCSB) model structure was investigated. The relationship between the transmission coefficient,
(CT) and the reflection coefficient (CR) with environmental and structure variables are examined. The physical
modeling concluded that SCSB is effective in intermediate depth in the region of 1.5<kh<2.0. In this region,
the value of CT and CR are optimum where the CT value is 0.28-0.49, and the CR value is 0.28-0.52.
