Tsunami wave is a succession of waves produced by movement of great volume of water which usually occur in the ocean. During its propagation in shallow water region up to the inundation limits, the tsunami bore wave transports bed materials i.e. sediments believed to amplify the damage towards coastal structures along its path. The damage and danger that can be caused by the tsunami wave are essential to be studied in order to reduce the amount of damage. Besides, the suspended solid level might alter the rheology of the waves i.e. from the Newtonian to non-Newtonian fluids. Consequently, the alteration of the fluid constituents would affect the hydrodynamics of the waves. As such, rigorous experimentations were conducted to evaluate the extent of viscous and density influence on the wave hydrodynamics and the subsequent loadings on a vertical test model. The main objective for this experiment is to assess the wave kinematics and flow condition for bore propagating over a horizontal dry flatbed subjected to Newtonian and nonNewtonian fluid of varying solid concentrations as well as to investigate the impingement forces acting on a vertical structure subjected to Newtonian and non-Newtonian fluids of different mixture concentrations via physical modeling.
