The identification of critical glacial lakes is based on remote sensing method in which several criteria related to glacial lakes, glaciers and physical condition of surrounding area is considered to assess potential for future outburst and possible glacial lake outburst flood (GLOF).
Application field:
Visual observation and mapping of glacial lakes and associated glaciers along with physical features in the vicinity using Landsat data series provides vital information to identify critical glacial lakes with potential for an outburst in future. This allows early identification of potential hazard and makes a timely investment on risk management interventions including outburst mitigation options.
Methodology:
Key results:
There are over 200 critical glacial lakes in the Hindu Kush Himalayan region some of which are monitored regularly using remote sensing and occasionally in the field
