Expansion of moraine-dammed glacial lake in the central Himalayas from 1977 to 2009

The glacial lakes from 1977 to 2009 in the Nepal-China border region were investigated using satellite imagery. 247 ice-contact or ice-proximal glacial lakes with total area of 126.3km2 in the study area were identified in 2009. The expansion rate of growing lakes are approximately <70m/year in length and 0.12 km2/year in area since1977, respectively. The glacial lake growth rate keeps increase from 1977. The expansion rate of growing lake on southern side is greater than that on northern side.
