  • The modified version of the perabolic mild-slope equation is derived by the variational principle.The modified parabolic mild-slope equation is shown to be capable of describing for wave propagation over a bed consisting of substantial variations in water depth and to predict wave refraetion-diffraetiort with three-dimension topography.The modified parabolic mild-slope equation has been compared with parabolic mild-slope equation.Numerical examples demonstrate the practical applicability of the modified parabolic mild-slope equation.
