The assessment of stability of grand Dallagkaus landslide in reservoir of Zaramag hydro power development, Russia

摘要

The Grand Dallagkaus landslide is situated on the Mamisondon River which is a left bank tributary of the Ardon River. The depth of the Dallagkaus landslide is up to 80 m and its volume is about 13 mln m3. The length of the slide body is about 950 m, while its averaged width varies from 80 to 400 m. The Grand Dallagkaus slide is devoid of wood cover while the surrounding stable areas are covered with rather a dense forest, which serves the evidence of the slide body movements.
