| The problem of interaction of surfacy gravity waves with a washed away slope is considered. On the basis of conventional approach, the balance equation for the depth H and the sediment discharge Q is supplement by semiempirical relati-onships for inclined coast. As a result, the parabolic equation with variable coeffcients is obtained which is integrated by the method of finite differences. Evolution of bottom sediments is shown and analyzed. Also generalized model of sedimentation desribed by the equation of hyperbolic type with dissipation is presented. |
