The conditions determining the development of exogenous geological processes on the coasts studied were characterized. They are: the type of coast, the tectonic construction and the direction of tectonic movements, maritime relief, lithological composition of the coasts. Genesis, morphometric characteristics, granulometric and material composition of the beaches forming here are described.
