| Outline of Final Research Achievements |
This study provided a novel mechanical model imposed at a toe of tsunami running up over arbitrary ground conditions. This model has been confirmed to provide appropriate dynamic responses of the run-up waves and to estimate accurate flood areas. The specific research achievements are; (1)improvements of the imaging technique to measure dynamic three-dimensional water surfaces, (2) introduction of a phase-field model to three-dimensional fluid flow computations, (3) validations of the proposed model, and (4) establishing new computational framework for run-up tsunami computations. The proposed model has been applied to the two practical cases of tsunami floods, in urban area and river basin, observed in the 2011 Tohoku earthquake tsunami, which provided distinctive flooding processes depending on the ground conditions.
