The Vertical Line Source Green's Function method (VLG method) has been shown to be effective for estimating wave height distributions in harbors with arbitrary configurations. This method has also been extended to cases where there are variations in water depth, such as navigation channels and sea ponds. In this study, we focus on how to apply the boundary integral equation analysis to multiple connected water depth regions in a harbor, using the extended VLG method. We show that for a complex harbor region with separated water depth areas, the boundary integral equation of the analysis can be applied as if these areas were interconnected by narrow passes, treating the domain as a simply connected one. Additionally, we consider the wave transmission through detached breakwaters and jetties to examine the sheltering effect in a harbor. Our numerical examination provides insights into the effectiveness of the VLG method for modeling wave behaviors in complex harbor environments.
