Hydraulic experiments on tsunami wave pressure were conducted in the presence of multiple rectangular structures. A 2D depth-integrated flow simulation based on the unstructured grid system was carried out to reproduce run-up tsunami deformation. Tsunami wave pressure was calculated by using inundation depth and horizontal velocity at the front of the land structure. Even though splash due to the initial impact of the leading edge on the structure cannot be reproduced by the 2D simulation, the evaluation method of tsunami wave pressure could reasonably estimate the vertical distribution of the maximum tsunami pressure. Tsunami wave pressures calculated by CADMAS-SURF/3D were in good agreement with the experimental results on the condition that the evaluation method using the 2D simulation results cannot replicate.
