ASSESSMENT OF PROPAGATION CHARACTERISTICS FOR TSUNAMI WAVE ASCENDING RIVER

Min Roh, Mohammad Bagus Adityawan, Hitoshi Tanaka

Abstract


Tsunami wave ascending rivers is one of the important phenomena in river and coastal engineering. It is regarded as a potential disaster due to the tsunami propagation. The features of the tsunami wave in the river can be explained by physical parameters. This study focuses on the verification of an estimation method for the tsunami parameters. A numerical experiment was used to evaluate the suggested method using measured water level data. The method applied to real observation data during the 2011 Tohoku Tsunami. The tsunami characteristics along the river were confirmed by the calculated river discharge and flow velocity induced by the tsunami.

Keywords


The 2011Tohoku Tsunami; river discharge; tsunami flow velocity.
