The combination of physical laboratory experimentation and the coupling of two CFD numerical models was employed to study the hydraulic behavior and run-up in different typologies of hybrid solutions for coastal flood protection. The results obtained reveal significant discrepancies between the run-up measured in the laboratory and the run-up that can be obtained through traditional engineering equations after propagating the waves through vegetation using a numerical model. This highlights the importance of reconsidering the approach typically used to analyze such solutions.
