In countries and areas where oceanographic phenomena like waves are not observed, ad hoc coastal structures are designed based on experience. This study applies various kinds of analytical data to the coastal master plan of Davao City, the Philippines, where observation data are scarce.
The study conducted downscaling wave analysis using the WAVEWATCH III-SWAN coupled model with long-term wave hindcasts to obtain probability waves for the target coast. This study also conducted storm surge analysis as compensation for the missing period of tide observations to derive probability tide levels. The results of evaluating the planned road revetments’ function with such analytical data clearly indicated that the armor units of the revetments were stable, but the elevation of crown heights was insufficient in some sections. Finally, a master plan including an action plan by 2045 was developed based on the results of this study.
