FLOODING IN NEPAL May 7, 2012Posted by wmmbb in Natural Environment.
The floods that occurred in Western Nepal have described as the worst flooding in living memory.
The Times of India reports:
Thirteen people were killed as raging flood waters from the swollen Seti river swept away houses and farms near the tourist resort of Pokhara on Saturday. Around 40 people are still missing in the floods triggered by a glacial lake burst in north western Nepal, even as the swollen river smashed into huts and buildings.
The calamity occurred in the remote Kaski district, 200-km away from the capital, Kathmandu.
A number of shacks in Kharapani village were washed away in the deluge. Three foreign trekkers are among those dead. “Among the dead is Ukranian while three Russians are missing,” said superintendent of police Shailesh
This video attributes the cause to a glacier lake outburst and observes climate change is happening:
Glacier thinning and retreat in the Himalayas has resulted in the formation of new glacial lakes and the enlargement of existing lakes due to the accumulation of meltwater behind loosely consolidated end moraine dams. Such lakes are inherently unstable and can be subject to catastrophic drainage (glacial lake outburst flood or GLOF), which is a potential source of danger to people and property in the valleys below them.
In my mind I was linking the La Nina effect that explains the wet summer we had with something similar with the monsoonal rains arising from the Indian Ocean resulting in heavier rain over the Himalayas which combined with the effects of melting glaciers combining to create the floods.
