We investigate the effects of storms on finite amplitude sand wave growth using a new idealized nonlinear morphodynamic model. We find that the growth speed initially linearly increases with sand wave amplitude, after which nonlinear effects cause the growth to decrease. This finally leads to an equilibrium amplitude. Storm processes lower the equilibrium amplitude compared to the fair-weather (tide-only) situation.
