Abstract

A shore-parallel canal, called Teizan Canal, had been constructed since late 16th century along Sendai Coast, Japan mainly for navigation purpose. It is estimated that the canal contributed to tsunami mitigation to some extent during the 2011 Great East Japan Tsunami. In order to investigate its effect on tsunami energy reduction, a numerical model based on shallow water equation (SWE) is applied to simulate the 2011 Tsunami in Sendai plane area. A series of numerical experiments are carried out with different cross-section of shore-parallel canal to investigate effectiveness of canal shape for reducing tsunami energy during the extreme tsunami run-up into the land area.
