Impact Of Glacier Changes In The Himalayan Plateau Disaster

Excluding the polar areas, the Hindu Kush-Himalayan (HKH) Plateau and its surroundings have the most glaciers. The Himalayan Plateau and its surroundings have declined gradually over the past 100 years. However, unexpected shifts have taken place since the 1990s in the condition of the glaciers. The massive loss of the small glaciers, in particular, was more extreme than the failures of the gigantic glaciers with an area about a km2. The approximate decay calculated through the Remote Sensing techniques has shown that from 1989 to 2009, the longitudinal region of Siachen Glacier decreased by 5.9 km in total area. To measure their potential strength to average surface runoff, a variety of standardized land cover climatic variables is being used to describe the spatiotemporal distribution of snow storms, and evaporation. The spatial trend primarily represents an irregular shift in the Himalayan glaciers and the surrounding areas. This research examined and disclosed the spatiotemporal distribution and development of Moraine-Dammed (MD) lakes and Likely Hazardous Glacier Changes (LHGC) in the Himalayan Plateau (HP). A unified degree of disaster for county-based Glacier Eruption Floods (GEFs) by integrating LHGC risks, geographic visibility, susceptibility, and using the hierarchical analytic process and comprehensive weighted method. The comparison between current and proposed methods is made by using the analysis hierarchical process, a proposal methodology in dynamic environments where several factors are taken into consideration in prioritization and selection of alternatives. GEF are types of outbursts that are triggered by a system that has a glacial lake collapse. An occurrence like the one in which a glacier is melting or overflowing in a water body is known as glacier run. The findings show that in the Himalayan plateau, there are 662 MD lakes, covering a complete range of 198.6 km2, of which 301 lakes covering a total area of 80.21 km2 are identified as LHGCs. The number of lakes declined by just 3.13% relative to 1989-1999, although the overall lake region has increased by 19%. The GEF disaster frequency regionalization findings show the distribution of historical GEF disaster sites.
