Local Scouring from Tsunami Waves Considering the Effect of Soil Liquefaction

Key Points

• Local scouring is significantly influenced by the effects of soil liquefaction during tsunami events.
• Key evidence includes the interaction of hydrodynamic forces with liquefied soils, leading to increased sediment transport.
• Analysis of hydrodynamic conditions shows that soil liquefaction greatly enhances scouring depth and area during tsunamis.
• These findings highlight the need for improved designs in coastal infrastructure to withstand liquefaction effects during tsunamis.
