The applicability of a numerical model calculating waves in partial reflection region is examined. The model used in this research is a Boussinesq-type wave transformation model provided by Port and Airport Research Institute in Japan (NOWT-PARI, Ver4.6 β for short), which has a function of evaluating reflected waves at porous layer boundary. The feature of this model is that the reflected waves are reproduced without adjusting any parameters at the reflection boundaries. Experiments with a large scaling model of Nase harbor, Kagoshima prefecture, were conducted. Experimental results were compared with numerical results. Good agreements were obtained for wave height distribution.
