• Overtopping
• Vertical walls
• CLASH
• Horizontal foreshore
• Sloping foreshore

In this paper, a comprehensive nonlinear regression analysis has been conducted on widely known dimensionless parameters associated with the overtopping phenomena as one of the highest priority design criteria in seawall design, using CLASH (Crest Level Assessment of coastal Structures by full-scale monitoring, neural network prediction, and Hazard analysis on permissible wave overtopping) database, as the most viable source in this regard. Accordingly, new formulae have been put forward for calculation of mean overtopping discharge at vertical walls on horizontal as well as sloping foreshore. It has statistically shown that presented formulae have a comparatively better correlation with related CLASH data when compared with the existing ones. Therefore, implementing new formulae will hopefully result in a more reliable design of vertical walls with respect to overtopping discharge performance.
