TSUNAMI RUN-UP CONSIDERING TIME VARIATION OF DENSITY OF INUNDATION WATER

Aiming for the advancement of tsunami load, historical and/or prospective scale evaluations, practical empirical formulas evaluating friction factor K inundation flow and density ρ water over a movable bed, which can be applied to run-up theory, are proposed using experimental data whose amount (range) is increased (expanded) by carrying out additional experiments on with sediment, verification above theory under uniformly sloping bed condition provided. Series solutions higher universality sediment in both depend time, derived conditions depending an incident bore height h1 at shoreline (or initial stored depth), slope i, median particle diameter d50 material, examples shown. The applicable case that independent i.e., without or fixed bed. Including validity one also verified through comparison distance.
