Abstract
A 260 m high dam is under construction across the Bhagirathi River in the Garhwal Himalaya (India) to impound 3.6 x 10(9) m(3) of water at t he maximum reservoir level. The reservoir will extend over a distance of about 44 km in the Bhagirathi Valley and about 25 km in the Bhillan gna Valley. A landslide hazard zonation map of the reservoir area has been prepared. The relative influences of six major causative Factors have been calculated to identify the important controlling factors in high hazard slope facets.
