On the basis of refernce [3] .the effect of wave energy loss caused by bottom friction developed on the seabed topography upon the refraction and defraction of water waves calculated with parabolic equations is considered in the paper. The calculated results show that the factional formula for friction drag, which has been used in solving the equations for gentle slopes, has a high accuracy in numerical calculations. The procedures given in this paper may be used to calculate wave propagation in exposed water, in large harbours and bays for practical engineering projects.
