Abstract

Analysis of the long-term dynamics of underwater slope is necessary to identify the differences and common trends in the evolution of the different types of shores and for long-term forecast of geomorphic dynamics of coastal zone. The dynamics of a coastal profile exemplified by three different types of sandy beaches in the northern part of the Black Sea, was explored on the basis of cartographic data and individual measurements on profiles. The transformation of a coastal profile was revealed that can be associated with different budget of coastal marine sediments during the study period, with the effect of varying structure and intensity of storms and with dynamics of relative sea level due to tectonic conditions. The results prove the stability of the outer border of the dynamic zone defined by wave regime during the analyzed period.
