Glacial Lake Outburst Flood (GLOF) - The Himalayan tsunami in a village in Nepal
A first hand account of Glacial Lake Outburst Flood (GLOF) in Dudh Kosi in the Himalayas Posted on 29 Dec, 2009 04:47 PM

It was an uncharacteristically sunny day for the monsoon, with blindingly clear skies. Namgye Chumbi was weeding his potato garden in Phakding by the Dudh Kosi on the morning of 4 August 1985.


There weren't too many trekkers on the trail. The Dudh Kosi was tumbling noisily over boulders nearby. Around two in the afternoon, the river went quiet. Namgye sensed danger.

"I noticed that the white water had turned muddy brown, and in the distance I heard a thundering sound like an approaching helicopter," recalls the 50-year-old farmer. "I looked upstream and saw this huge wall of dark brown water approaching very fast."

Water resources in Jhansi and Tikamgarh districts (Madhya Pradesh) - A status report (2007)
A status report on the Bundelkhand region and information on sanitation practices Posted on 03 Oct, 2009 05:56 PM

This status report prepared by Development Alternatives contains brief background information about the Bundelkhand region, details about the physical profle (topography, drainage and river systems, land usage, climate, rainfall), water resources information (water demand, availability, supply and accessibility) and information on sanitation practices (toilets, personal  hygiene, solid waste management, liquid waste disposal, availability of water for sanitation).

The first project was conducted by the BAIF Development Research Foundation in the Hassan District of Karnataka. They created a linked network of 350 farm ponds covering 700 hectares of the watershed.

Impact of climate change on major river basins in India: The Indo-Gangetic-Plains
The effect of climate change on the Indo-Gangetic-Plain region will primarily be by the glacier melting impacts and heat waves and extreme climates Posted on 28 Aug, 2009 02:14 PM

The Indo-Gangetic Plains, formed by the drainage systems of the rivers Indus and the Ganga, stretch across the countries of Bangladesh, Nepal, India and Pakistan covering approximately 401.72 million hectares of land.

Impact of climate change on river deltas and other coastal areas in India
While global warming is a matter of worldwide concern, among the most vulnerable areas are the coastlines of less developed tropical countries such as India. The river deltas, in particular, are already facing the brunt of climate change and these adverse impacts can be expected to increase dramatically in the course of this century.

The effects are most visible in the Sunderbans. Literally the 'beautiful forest', these wetlands at the mouths of the Ganga and Brahmaputra river systems are among the largest mangrove forests in the world. About 62% of this area of some10000sq km lies in Bangladesh but there is a significant Indian portion in the state of West Bengal.

Quick reference: Climate change impacts on freshwater ecosystems in the Himalayas (CCIFEH)
Climate change impacts on freshwater ecosystems in the Himalayas (CCIFEH) is a joint initiative of WWF-India and WWF Nepal, funded by WWF-The Netherlands. Posted on 26 Aug, 2009 04:01 PM

The programme entails a panorama of actions working towards understanding future climate change impacts on Himalayan river ecosystems and vulnerable communities for the development of adaptation strategies; implementation of pilot sites; and raising the awareness of climate change impacts on Himalayan river basins, in addition to urging specific adaptation strategie

Glacier lake outburst floods: Wrecking havoc to life and property in the Himalayan region
A glacier lake outburst flood (GLOF) is caused when the glacial lakes burst their banks and cause widespread floods. In the past two decades there have been a number of glacier lake outburst floods. The increase in the melting of glaciers have led to this phenomenon. Posted on 26 Aug, 2009 03:47 PM

These floods cause havoc with human life, flora and fauna of the area and the infrastructure in the region.

The Dig Tosho Glacier lake outburst in August 1985, destroyed the nearly completed Namche hydropower plant and all the rails, roads, and other infrastructure in its course.

How climate change has affected Ladakh: The region has seen unusual floods in July 2005 and August 2006
Ladakh is known as the cold-desert and has severe conditions and is barren and arid. The region has seen unusual floods in July 2005 and August 2006. Posted on 26 Aug, 2009 03:36 PM

It is in Jammu Kashmir and is bordered by the Himalayas and the Karakoram mountain chains. Ladakh and its water sources are almost entirely dependent on the glaciers and snow-melts and changes in water systems can be directly attributed to changes in the glaciers and thus climate change.

Impact of climate change on the Himalayan glaciers
40% reduction has occurred in the Himalayan glaciers in the last 40 years. 67% of the glaciers have retreated in the last decade. Gangotri is retreating at the rate of 28 m per year. Global warming and its consequent melting of glaciers would result in floods, fast and furious run-offs, erosion of the topsoil and sedimentation of the rivers. This could also lead to changes in the course of the rivers in the region. Posted on 26 Aug, 2009 03:30 PM

The Himalayas' permanent ice cover is around 97,000 sq.km. with 12,930 sq.km. volume of ice and snow: 10-20 % are covered by glaciers and 30-40% are seasonal snowfalls. The Himalayan streams and rivers are fed by the melting of snow and ice of approximately 500 sq.km / year.
