摘要:On the background of global warming, climate changes have mostly affected the contact zone of the hydrosphere and lithosphere, the coasts of oceans and seas. The sea level fluctuations and the activity of storm flow and thermal mode have had a significant influence on the complex morphodynamic processes in the coastal zone. The coasts of oceans and seas are distinguished by their anthropogenic significance and occupy 72% (except cryogenic coasts) of the world ocean coastal zone. The sustainability of sea coastal zone is directly connected with eustatic, epirogenetic and wave processes. In the modern period the wash-off area of the world ocean coasts and the increasing of intensity are directly caused by the above mentioned factors.
