Fig. 7From: Should tsunami simulations include a nonzero initial horizontal velocity?Comparisons of shallow water simulations with full-physics simulations for the Tohoku geometry, where each row uses a different value of rise time \(\tau\) when setting initial velocity in the shallow water model. Left column Initial condition on depth-averaged velocity used for the shallow water code, as per Eqs. (8) and (9). Right column Tsunami profile at 500 sBack to article page
