On the mechanisms of dangerous sea level rise in the eastern part gulf of Finland and possible reasons for the increase in their frequency in the second half of XX and the beginning of the XXI century

Abstract

In the last decades in eastern part of Gulf of Finland has considerably increased frequency of dangerous sea levels rises. The results presented in Fig. 1 indicate that over the past 30 years the number of floods in the Neva estuary increased by 1.6 times. Despite the startup in 2010 of the complex structures protecting St. Petersburg from flooding (CPS), dangerous sea level rises continue to cause damage to coastal areas located to the west of the dam. Increasing number of floods, existing gaps in our knowledge about their nature, force of researchers to continue explore this dangerous natural phenomena in order to develop it more accurate prediction.
