Landscape transformation during hydroelectric power plant building: a study of Boguchany Reservoir in Angara River

The paper covers changes in the landscape (geographical environment) caused by the erection of the Boguchany dam (and the Boguchany Reservoir), the fourth in the Angara River cascade. Investment plans related to the construction of the reservoir assumed that its primary function would be the production of electricity in a hydroelectric power plant integrated with the dam. The reservoir, on which filling operations started in 2012, is intended to occupy the entire 375 km of valley. The full length will be reached when the water level is achieved at 208 m a.s.l. The reservoir will have a surface area of 2326 km2, a shoreline length of 2430 km and a width ranging from 1.2 to 15 km. As a result of the Boguchany Reservoir investment process, hydrotechnical, transport and transmission infrastructure has emerged in the Angara River valley. Within the flooded area, natural (e.g. riparian shrubs and forest communities) and cultural (rural and agricultural) landscapes have been replaced by that of a lake district. Devastated landscape was also temporarily present. In the next stage, the reservoir will be assimilated in by the environment; this process will be affected by human activity in the coastal zone.
