Tsunamis caused by subaerial landslides are less frequent than tsunamis caused by fault movements, but they cause significant damage, such as the 2018 Indonesia's Sunda Strait tsunami. Therefore, establishment of an appropriate tsunami evaluation is required. Although kinematic landslide models and two-layer models have been proposed as two-dimensional analysis methods, there are few examples of direct comparison of water level time histories with experiments as verification. In this study, the reproducibility analysis using the two-layer model considering dispersibility was performed for the hydraulic experiment, and its applicability was demonstrated.
