On the impact of the tectonic subsidence of coast on abrasion regularities

Abstract

Impact of tectonic subsidence on sea coast evolution was studied with reference to development of eastern abrasional coasts of the Azov Sea. Tectonic subsidence has been proved not only to accelerate the coast abrasion but to change the character of the process: while under conditions of constant sea level the shore abrasion terminates in equilibrium profile, there is no natural stabilization of the coastline under subsidence conditions, the coastline constantly retreats with the rate increasing as the tectonic subsidence accelerates.
