Landslide dams in the high mountains of india, nepal and china - stability and life span of their dammed lakes

Abstract

This paper attempts to work out the stability conditions of 20 landslide dams in the Indian and Nepal Himalayas as well as two in China. All of them formed lakes upstream by damming the main river. The categories of study areas that they created differ in their shape, their volume and composition of the deposited landslide material, as well as in the size and life span of their former dammed lakes. This representative group of case studies affords the opportunity to obtain new results on this rare phenomenon.
