A numerical model based on Reynolds Averaged Navier-Stockes (RANS) equations was developed1) to account for the effects of wave-induced turbulence. In this study, a NEWFLUME model is applied to simulate the recent Great East Japan Earthquake and Tsunami 2011. A series of numerical experiments, which has topography similar to Sendai Coast in northeast part of Japan where was severely damaged from the 2011 Tsunami event, were carried out to investigate the sensitivity and effects of the shore-parallel canal in reducing tsunami energy. Numerical results show that the Kita-Teizan Canal which is parallel to the shoreline in Sendai Coast has significant effect in reducing tsunami energy and plays an important role in the mitigation of tsunami impacts.
