Coastal zones have consistently been among the most appealing settlement areas due to their proximity to the sea, rich natural resources, and the high quality of life they offer. However, these regions are affected to climate change impacts, such as sea-level rise, storm surges, and an increased intensity of extreme weather events. Rubble-mound breakwaters, especially low-crested structures, are frequently utilized among the portfolio of potential typologies. However, it is expected that the variability of climate conditions will induce loss of functionality and structural integrity in the coming decades. The objective of this study is to propose a portfolio of alternative solutions for emerged or quasi-emerged rubble-mound breakwaters that are perceived as highly impacting structures. To achieve this goal, a hybrid approach is followed, including the best of physical and numerical investigations to get a better insight of their hydraulic performance.
