Physiography

This paper from the GIS Development site attempts to find out whether Ground Water Information System (GWIS) and Geographic Information tools can be useful as efficient exploration methods to gain an impr

Saurashtra is the peripheral region along Coastal Gujarat. It is composed of a Central basaltic plateau that rises 100 to 200m above mean sea level with an average annual rainfall of about 600 mm. The rainfall is concentrated in a few days during which the incident rainfall leads to flashfloods draining into the sea.

In the absence of groundwater instrumentation networks in India, the knowledge of local well drillers about the location, quality, etc of groundwater aquifers is invaluable.

It is with great disappointment that Raksha Sutra and Uttarakhand Nadi Bachao Andolan received the news from the report in Amar Ujala, Dehradun 27.02.09 that the Uttarakhand High Court has granted a stay to the Central Government Order suspending the work on the Loharinag , Pala (600 MW) hydroelectric project. The work on the project has begun with hardly a break in its stride. The Public Interest Petition filed by Rural Litigation and Entitlement Centre, a Dehradun based NGO filed for a stay stating that neither would the natural flow of the river be affected nor is the project causing any environmental damage is a total falsehood. The petitioners have deliberately misled the High Court. They have not visited the site for themselves and have filed for a stay from the sanitised environment of Dehradun. We who live and work in Uttarkashi know the truth. This is not the first instance that this NGO has taken legal action to restart projects that have been stopped because of their dubious benefits. It is quite clear that unlike its name this NGO is working not for rural entitlement but rather for the entitlement of vested interests. This is very saddening. The environmental impact of the project is enormous. Entire mountainsides have been scarred and shorn of their green cover. Thousands of tonnes of excavated rock from the tunnel construction have been dumped on the riverside and threaten to block the flow of the river with the onset of monsoon. The dust being churned day and night by the hundreds of dumpers and trucks operating on the project is choking all life on both sides of the river. Fields that were the mainstay of the primarily agricultural community are lying barren because no growth has taken place for the last 3 years despite the best efforts of the farmers. Pastures which sustained the livestock of the village people have been devastated. Representations by the people to the government and NTPC have yielded no satisfactory results. We have photographic and video evidence of this.

Dr. Jagannath Mishra, former Chief Minister of Bihar, has given a pathetic description of floods in Bihar. He said that "Nobody from the government has gone to Saharsa so far. If the people in Saharsa are surviving, they must be saying that we are engulfed in water since ten days and nobody is there to think about us. This is quite worrisome. I will suggest that we must try to look after those surviving there. We must try to save them, whether by boats or a helicopter.. The flood in Saharsa is not a flood, this is unprecedented¦.we cannot call it a flood, it is a deluge." But wait, he is not talking about the recent floods (2008) in Bihar. He was making a speech in the Bihar Vidhan Sabha on the 13th September 1984 about a similar incident that took place on the 5th September 1984 near Navhatta in Saharsa district of north Bihar when the Kosi had breached its embankment at 75th kilometer south of the much talked about Bhimnagar Barrage and come out of the jacket just as it happened at Kusaha this year. Obviously, the powers that be refuse to take any lessons from the past mistakes and their executive wing, the Water Resources Department, is immune to any criticism and learning. The 1984 incident had uprooted nearly half a million people from their homes and hearths and engulfed 96 villages spread over 7 blocks of Saharsa and Supaul districts then. They could return to their homes only after the Holi festival in March 1985.

All is not well with the High Level Expert Group (HLEG) constituted on an order of the Government of India to determine the flow required to keep the Bhagirathi river 'alive and to ensure perennial environmental flow in the river'. It may be recalled that on June 30, 2008 the Government of India committed itself to "suitably ensure perennial environmental flow in all stretches of river Bhagirathi."This commitment was made in response to a representation of the Alumini Association of IIT- Kanpur to the Prime Minister of India requesting his intervention in the fast-unto-death undertaken by Dr. G.D. Agrawal , a former Dean of IIT-Kanpur -- to ensure the natural and uninterrupted flow of the Bhagirathi river between Gangotri and Dharasu (Uttarkashi). Subsequently the Ministry of Power, GoI, directed Shri R.S. Sharma, Chairman & Managing Director of NTPC, to constitute a high level expert group. The biggest problem with the HLEG is that it lacks the necessary scientific expertise to comprehensively address the issue. In a letter to Shri R.S. Sharma, rejecting his invitation to be a member of the HLEG, Dr G.D. Agrawal wrote, "Several members of the HLEG as constituted (including its Chairman) fall extremely short on any sort of expertise on river ecology and environmental flows...The commitment of most proposed members towards conservation of Bhagirathi Gangaji as the mother of India's faith, unity and culture is also questionable and I cannot afford to provide credibility to its deliberations and conclusions by being an ordinary member of the group."

About the Report: The flood situation report has been a joint effort of Megh Pyne Abhiyan's (literally clouds' water campaign, involving people around the issue of water and livelihood, and a functional network of grassroots organizations) partners - Gramyasheel, Supaul; Kosi Seva Sadan, Saharsa; Samta, Khagaria, Ghoghardiha Prakhand Swarajya Vikas Sangh, Madhubani; SAVERA, West Champaran; Luisa Cortesi and Eklavya Prasad in assistance with Santosh Jha of Gram Bharti, Raghopur.Supaul. For compiling the situation report, two days of field visit was undertaken by the team, involving extensive interaction with affected villagers from India and Nepal, discussion with members of civil society groups, deliberations with government officials (Sub Divisional Magistrate and Dy Superintendent of Police, Tribeniganj; District Magistrate, Supal) and internal exchange of idea between the partners of Megh Pyne Abhiyan (MPA) and the supporting organizations. During the field visit, the group started to explore the option of establishing a district level coordination group comprising of eminent personalities and professionals, representatives of non governmental organizations and media, to coordinate and steer the rescue and relief work with individuals, government agencies, non government organizations, donor agencies, corporate bodies etc. Hence, on 25th August during a district level meeting of local organizations, activists and donor agency, a consensus was reached to set up a coordination group, named as the Flood Action Coordination Group (FACG), Supaul.

General overview of the River: On the 18th of August the eastern embankment of Kosi near Kusaha in Nepal's Sunsari district breached. The breach itself has caused colossal loss of life and property in the south east tarai region of Nepal and in six districts of north Bihar, affecting more than 2.5 million human lives. After the breach, the river has shifted its course nearly 100 kilometres (kms) eastward from its earlier course (which use to pass through the districts of Supaul, Saharsa, Madhubani, Darbhanga and Khagaria).

Several threats have emerged in recent years to the pristine Himalayan rivers of Uttarakhand. These include: (i) the proposed construction of 220 dams (ii) the drying up of rain fed rivers due to deforestation and deforestation of their catchments (iii) release of untreated sewage from river side towns and habitations and (iv) illegal sand mining of river beds.
