From: Should tsunami simulations include a nonzero initial horizontal velocity?
Initial conditions for tsunami problems as determined by the adjoint method. The dotted orange line is the final tsunami profile of a zero gravity simulation (the tsunami doesn’t propagate). The green lines are the sea surface height and depth-averaged horizontal velocity fields determined by the adjoint method. These are the most consistent choices for initial conditions \(\eta _0(x)\) and \(v_0(x)\)
