Comparisons of shallow water wave simulations with full-physics simulations for \(\theta = 10^{\circ }\), 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). We run the shallow water code with two different values of \(L_H\) (see legend). Right column Tsunami profiles at the final simulation time, comparing the full-physics result to the two different shallow water simulations
