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.

在巴厘岛新开发的旅游海岸中，建立了基于DELFT3D的海啸发生和淹没数值模型。它使用基于先前海啸历史和地震潜力的假设海啸波。该模型在倾斜的海滩上使用溃坝模型进行了验证，以了解网格，粗糙度和湍流公式的影响。发现网格依赖性测试很重要，尤其是在发生湿润和干燥过程的近岸地区。最后，考虑流速来计算海啸危险等级。敏感性测试可以帮助确定模型的不确定性，以确保更好地了解海啸危害。
