Abstract

A numerical model based on DELFT3D for tsunami generation and inundation is performed in newly developed tourism coast in Bali. It uses a hypothetical tsunami waves based on previous tsunami history and earthquake potential. The model is validated using a dam break model on the sloping beach to understand the influence of grid, roughness, and turbulence formulation. Grid dependency test is found to be important, especially on nearshore area where a wetting and drying process occurred. Finally, the tsunami hazard rating is calculated considering the flow velocities. Sensitivity test could help to determine model uncertainty to ensure better understanding on tsunami hazard.
