Glacial lake change risk and management on the Chinese Nyainqentanglha in the past 40 years

GLOF is low-frequency event, but it often causes enormous loss and damage of life, property and human environment in downstream regions. The economic losses caused by GLOF are much higher than the project costs to early consolidate moraine dam and release flood waters. Glacial lake outbursts can be very difficult and expensive to control, but regional exposure and vulnerability of exposed elements downstream can be reduced by improving adaptation capacity and risk management level.
