Abstract
For the advancement of the tsunami load and scale evaluations, the dependency of the density of the tsunami inundation water on the hydraulic quantities, and the dependencies of the tsunami run-up distance, deposit distance, deposit thickness on the density of the tsunami inundation water are examined through a devised hydraulic experiment. Within the experimental range of this study, it is veryfied that the density of the tsunami inundation water depends on Froude number of the incident tsunami and the sediment grain size, and the relative tsunami run-up distance (=the run-up distance of the inundation water with the sediment/the run-up distance of the inundation water without the sediment), ratio of the tsunami deposit distance to the tsunami run-up distance, ratio of the mean tsunami deposit thickness to the tsunami deposit distance depend on the density of the tsunami inundation water, and then four empirical expressions for those dependencies are proposed.
