Abstract
The features of the formation of the equilibrium profile of the underwater coastal slope as an example accumulative spits of the Yarylgach Bay and the Karadzhinskaya Bay are considered. The study is revealed that in the natural conditions a completely stable storm profile is not formed and relief deformations vanish. Using criteria to determine the provisionally equilibrium relief, it was revealed, that the time-period of the equilibrium profile formation depend on the bottom slope, and the volume of absolutely deformations is associated with the ruggedness of the original topography. With an average bed slope of 0.05 the formation of an equilibrium profile occurs in 8.5 h, with a slope of 0.02 – 12.5 h.
