From: Should tsunami simulations include a nonzero initial horizontal velocity?
Kinetic energy as a portion of the total energy in the ocean calculated at time \(t=0\), for shallow water models with a the idealized structure and b the Tohoku structure. As \(\tau\) increases, initial velocity and kinetic energy decrease while gravitational potential energy is unchanged. By comparing with Fig. 8, we observe that models with low misfit are those with negligible initial KE
