Numerical Assessment of Integrated Perforated and Recurved Seawall Designs for Tsunami Mitigation
Jin Chai Lee
Tsunami wave overtopping remains a major challenge for conventional vertical seawalls. Alternative seawall designs have therefore been proposed to address the overtopping issue. This study aims to conduct a staged numerical investigation to evaluate the hydraulic performance of solid, perforated, and integrated perforated–recurved seawall configurations. Tsunami-like waves were simulated in a numerical flume at two impoundment depths under dry and wet bed conditions. The results reveal that perf
