Abstract

 In order to improve the accuracy of numerical simulation on morphological changes caused by tsunamis, Simultaneous Coupling Method (SCM), which couples 2 dimensional shallow water equation model and boundary layer equation model, was applied to numerical simulation of tsunami runup in Kitakami River. Under the front of the tsunami wave, steep peak of bed-shear stress was observed, while the variation of bed-shear stress was similar to the variation of bed-shear stress based on manning's law, which has been commonl applied for standard model for tsunami propagation.
