Long-term variability of coastal profile in different geomorphological conditions (the case of black sea sandy coasts)

Analysis of the dynamics of coastal relief during long time scales allows us to define differences and general trends in the evolution of different coastal types. Long-term dynamics of various coastal profiles was explored on the basis of cartographic data and individual field measurements for different types of sandy beaches located in the northern and northwestern coasts of the Black Sea. The variability observed in the coastal underwater profile dynamics can be associated with various factors as: long-term variability of sediment budgets, bed dynamics due to storm intensity and relative sea level changes as a result of tectonic conditions. The results suggest a relative stability of the outer border of the dynamic zone defined by wave regime during the analyzed period.
