Аннотация:Prediction of the vulnerability of sandy seashores to storm spills is very
relevant, especially in connection with a possible increase in relative sea level caused
by tectonics and climate change. The morpholithodynamic justification of the bank
protection system makes it possible to transfer it to the category of nature-like ones
and reduce the estimated cost by tens of times. For Holocene barrier-shaped baybars,
when identifying vulnerable areas even on a “homogeneous” shore, the erosion
index can be used, which, as the presented results show, has sufficient sensitivity.
The experience of forming a beach in the area of erosion by restructuring the system
of megafestoon distribution of beach sediments seems valuable and interesting.
