Abstract

Abrasion in the eastern Gulf of Finland coastal zone is favored by geological and geomorphologic factors, e.g. weakness of Quaternary deposits, sediment deficit, bottom and coastal relief. Extreme abrasion events occur as a result of coincidence of long-lasting western or south-western storms, high water level, and absence of stable sea ice during such events. In the last decade extreme erosion events took place during autumn-winter seasons of 2006-07 and 2011-12.

Keywords
