Tsunami characteristics over the Shonai dune. a Geometry and cross-sectional slices within the gray area specified in the middle-right panel of Fig. 3, red circles indicate the highest locations along the cross-shore direction, and the thick interval was 1 km; b alongshore variations in the maximum run-up heights and the top elevation over the dune; c–e profiles of the dune and the maximum water surface elevation (inundation height) along the cross-sectional slices. Each line color in (b–e) indicates the dune profile (black) and the tsunamis in the F28, F30, and F34 source scenarios with the breakwaters (blue) and without (red)
