The motion of an ice ridge confined within an ice floe under the influence of semidiurnal tide and the wind is considered. The force of seabed soil reaction applied to the grounded keel is estimated taking into account additional surcharge pressure from soil embankment near the grounded keel. Two-dimensional trajectories of the ice motion, the shape of seabed scours and the height of soil embankment are calculated. The influence of the phase and incident angle of the tidal wave, the bottom slope and the yield stress of seabed soil on the shapes of seabed scours is analyzed.
