Short summary
This article presents the comparison of two numerical models that model tsunami inundation that incorporates the built environment of coastal communities. It was found that the 2-D model did not accurately capture the important details of the flow near initial impact due to the transiency and large vertical variation of the flow. The 3-D model was able to capture transient characteristic of the flow, but at a much higher computational cost.
