Description
In this paper, a 2D numerical model using the high order WENO (Weighted Essenciallty Non-Oscillatory) scheme was proposed in order to predict a topography change in a harbor due to Tsunami. In this model, the FAVOR (Fractional Area/Volume Obstacle Representation) method was introduced into the governing equations. We applied the model to the small-scale experiment and the large-scale actual phenomenon in order to verify the validity of the model. Consequently, although the model was not able to reproduce local scouring around a breakwater where three dimensional flow was developed, it was clarified that the model can reproduce the topography change well by contracted flow.
