The Lithuanian coast of the south eastern part of the Baltic Sea represents a generic type of more or less straight, high-energy (in the Baltic Sea conditions), actively developing coasts that contain a relatively large amount of finer, mobile sediments, are open to predominating wind directions and are exposed to wave activity for a wide range of wave approach directions. The combination of the angular distribution of winds and the geometry of the coast are such that the wave-induced long-shore sediment transport is, in average, to the north over the entire Curonian spit and the mainland coast of Lithuania. Analysis of the field data performed by the G. Žilinskas (2008) from 1976-2007 revealed that the length of accumulative sections has been considerably reduced. Accordingly, the length of the gradually eroding sectors has increased in the end of the 20th century. In this study were analised potential variations in the long-shore sediment transport rate due changes of the wind wave directions.
