How can GLOF be prevented?
The most important mitigation measure for reducing GLOF risk is to reduce the volume of water in the lake in order to reduce the peak surge discharge. Downstream in the GLOF prone area, measures should be taken to protect infrastructure against the destructive forces of the GLOF surge.
What is meant by glacier flood?
Glacier outburst floods, or jökulhlaups, can be spectacular or even catastrophic. These happen when drainage within a glacier is blocked by internal plastic flow and water is stored in or behind the glacier. The water eventually finds a narrow path to trickle out.…
