Some problems of coast zone sediment budget studies (with reference to the Black Sea coast of the Ukrainian SSR)

Abstract

Stationary coast studies allow to calculate sediments budget at the Ukrainian coast of the Black Sea. Debris supply has been studied from cliffs and benches marine erosion, mineral part of shells, river solid discharge and eolian processes, mean total supply value being 30 400000 cu∙m per year. The debris volume is partly carried out of the coastal zone (21 950 000 cu∙m per year), partly fixed in built-up coastal forms and limens (6 700000 cu-m per year), or carried out by wind (550 000 cu∙m per year); loss through abrasion is l 200 000 cu∙m per year.
