Abstract

The present study investigates and evaluates the frequency of emerging extreme wind-induced water level fluctuations, which line up with the marks пїЅadverse eventпїЅ and пїЅdangerous eventпїЅ. The method we applied involved statistics throughout 1972-2016. Standard observation data from hydrometer stations of the Sea of Azov were processed. The study provides the strong evidence that this period had abnormal level activity: ? annual cycle of level had marks above the average sea level datum; rising tide was 0,19 cms per year ? range of oscillation and rare occurrence proportion of extremely high level have increased ? the number of dangerous and adverse events occurred 9 a year on average; the frequency of storm surges and dangerous events was 69% from them ? dynamic analysis of extreme wind-induced water level fluctuations highlighted the cyclic character of these dangerous events: emerging cycles of storm surges lasted for 10 пїЅ 11 years were revealed. The results obtained can be used for enhancement of monitoring efficiency of dangerous hydrological events their forecasting.
