Outline of Final Research Achievements

This study developed a high-resolution model which reproduced super-critical flows and local scouring behind coastal levees induced by large tsunami overflows. Unlike in conventional models, levees were represented as steep landforms, and thus flood flows over them could be seamlessly simulated. A scour indicator was constructed from local flow velocities through correlational analysis of the 2011 Tohoku tsunami cases. It enables us to perform vulnerability assessment of the coastal levee system against tsunami overflows.
