- Abstract
The shape and properties of long ship-generated waves approaching shallow coastal areas of Tallinn Bay are studied based on recordings of water surface time series. For typical leading wake waves non-linear effects become significant at depths of 10-15 m. A large part of waves (with the height over 0.4 m) have the shape of cnoidal waves in shallow areas with depths of 4-5 m. The shapes of the largest wake waves are close to the solitary wave solutions of the Korteweg-de Vries equation. Such waves excite considerably larger velocities of water particles than sinusoidal waves of equal height and length.
