Proposing a National River Authority of India (NRAI)
Posted on 23 Jul, 2010 04:29 PMIntervening at the urgency of the water situation of the country and need in larger interest of the people and nation from political, legal, social, administrative, commerce,trade,cultural, world tourism angles, apart from agricultural and drinking water angle; annual devastation by floods,and loss by drought. One single Authority, with P.M. as Chairman may hopefully bring expected and good results in river management; riverine rejuvenation - National River Authority of India
Here is a draft proposal for such an authority to be created.
We are looking for collaborations on making this a reality.
Please post your comments.

Augmenting groundwater resources by artificial recharge: A case study - Kolwan valley - A report by ACWADAM
Posted on 19 Jul, 2010 04:45 PMThis report by ACWADAM describes the results of a research study conducted under the DFID funded AGRAR project at the Kolwan site in Pune district of Maharashtra state in India. The research focused on studying the usefulness of artificial recharge to augment groundwater resources through watershed development.
An important criterion of the study was also to understand the impact of artificial recharge on already changing livelihoods in areas where watershed development was conducted on a large scale.
A rapid geohydrological study of microwatersheds from Bolangir district, Orissa state - A report by ACWADAM
Posted on 16 Jul, 2010 03:50 PMThis document by ACWADAM is a report of a rapid geohydrological assessment of some of the microwatersheds from parts of Bolangir district Orissa.
Bolangir district in Orissa forms a part of one of the hottest and backward regions of India with low land-productivity, and opportunities and technologies for agriculture in the district remain relatively unexplored.
Vagaries of rainfall and the underlying hard-rock geology further compound the problem and limit agricultural productivity to a great extent. Given such natural uncertainties, systematic implementation of a watershed management programme is the most viable avenue to overcome the problems of this region.
Bolangir district was thus selected as pilot area to conduct a pre-feasibility exercise for planning of water resources management. ACWADAM, Pune was invited, along with Samaj Pragati Sahayog, Bagli to conduct this pre-feasibility exercise.
A study of saline freshwater interface phenomena in the Mahanadi delta region (Orissa)
Posted on 10 Jul, 2010 10:40 PMThe subsurface aquifer systems in Mahanadi delta region in Orissa (India) is largely characterized by two groups of freshwater aquifer systems, both of which are prone to saline water mixing/migration with time and development:
- The south western Mahanadi delta region is represented by unconfined to semi-confined freshwater aquifers underlained by brackish/saline aquifer systems with a diffusion boundary.
- The north eastern parts of Mahanadi delta is represented by deep freshwater confined aquifers overlained by brackish/saline water aquifers with aquitard/ aquiclude boundary.
Conservation of lakes - Myths and realities of desilting
Posted on 09 Jul, 2010 11:11 PMDesilting is becoming a major component of any Lake Conservation Project now a days. The basic reasons given for necessity of desilting are - increasing the storage capacity and checking eutrophic conditions.
As it is not practicable to reverse the slow process of silting in the bed of lakes through which only silt can be removed, there is no word like 'desilting' in any standard English dictionary. What we are doing in the name of 'desilting' is practically 'digging' or 'excavation' of lake bed. By so called desilting, the original lake bed is disturbed which has far reaching adverse effects on the performance of the lake. Most visible effect is the increase in percolation rate resulting in heavy seepage losses through the lake bed as observed after massive desilting at Pushkar lake in 2009.
Renukaji Dilli Ke Nalon Mein - A documentary about the movement against the proposed Renukaji Dam Project
Posted on 18 Jun, 2010 05:22 PMThe Renuka Dam Project proposed over the river Giri Ganga (a tributary of the Yamuna) located some 300km away from Delhi, is a joint project of the governments of Himachal Pradesh (HP) and Delhi, to be constructed by the Himachal Pradesh Power Corporation Limited (HPPCL) in Sirmaur district of HP.
