Bottom feeding of longshore drift

Abstract

Abkhazian coast from the Bombar reid to the Gumista River mouth shows distinct discrepancy between beach-forming alluvium input and beach sediment quantity. The beach sediments are abundantly brought from the Gudauta shoal and can be easily identified at the, beach, On the basis of the observations the author revises the beach sediment balance and concludes on inadequacy of passive concrete shore-protecting constructions, the latter should be replaced by artificial fill.
