Abstract
In the recent past, coastal bridges have been subjected to critical damage due to extreme wave attacks during natural calamities like storm surge and tsunami. Various numerical and experimental studies have suggested different empirical equations for wave impact on deck. However, they do not account the velocities of the wave type properly, which requires a detailed investigation to study the impact of extreme waves on decks. Solitary wave assumption is more suitable for shallow water waves, while the focused wave has been used widely to represent extreme waves. The present study aims to investigate the focused wave impact on coastal bridge deck using REEF3D (Bihs et al., 2016).

Summary
Coastal bridges have been subjected to critical damage due to extreme wave attacks during natural calamities like storm surge and tsunami. VALIDATION Experimental study by Seiffert et al (2014) on a flat plate representing coastal bridge structure subjected to solitary wave forces is considered for validation of REEF3D modelling approach. Results The comparison of wave amplitude and vertical impact force on deck between numerical and experimental results show good agreement (Figure 2).
