Abstract

It is shown that accumulation of sediments and formation of the coastal banks on the Angara reservoirs occur in the areas of predominant abrasion shores. Abrasion produces more than 2 Mt/y of loose sediments, 40% to 90% of which participates in formation of coastal banks occupying only 1% of the reservoirs’ area. Granulometric composition, mineralogical and geochemical characteristics of the coastal banks sediments correlate with the abrasion shores rock composition.
