The importance of geological-geomorphological factors in the development of abrasion processes on the coasts of the Bratsk Reservoir, in the SE part of Russia

Ovchinnikov G. I., Maksimishina Y. S.

Landform Analysis

2002

Vol. 3

5--12

The construction of the Bratsk Reservoir, which is on the Leno-Angarskoje Plateau, favoured the active development of many exogenous geological processes, among which the abrasion of coasts is the most important, both in intensity and scale. Over the period of operation of the reservoir (1967-1998) the length of abraded coasts was 2160 km, or 36% of the total length of the coastal line. The maximum width of abrasion of the coast varies from 200 m to 750 m in unconsolidated sediments and is up to 90 m in rocks. The total area of abraded territory is about 5000 h. Nearly 131 000 000 m3 of the ground entered the reservoir basin due to abrasion. Geological-geomorphological factors are particularly important controls of the abrasion process.
