Wave Overtopping Discharge With Freeboard Determined by Imaginary Slope Method for Regular Wave Runup Height

Key Points

• To evaluate the protective performance of coastal defenses using runup heights set by regular waves in light of irregular wave overtopping.
• Utilized an integrated approach combining wave runup and overtopping using the IFORM model.
• Analyzed coastal defenses with freeboard based on regular wave runup height.
• Assessed the maximum dimensionless overtopping discharge and its implications for future design.
• Maximum dimensionless overtopping discharge reached approximately 3×10^-3.
• Identified scenarios where the set freeboard may be insufficient based on irregular wave conditions.
