Moving from paddy and sugarcane to less water-intensive crops such as oilseeds, pulses and millets can help resolve the Cauvery water dispute
What happens when two or more states are dependent on same water resource for agricultural purposes ? Do the states compete for the resource or are their needs sufficiently different from each other? What are the consequences of the competition for this precious resource? Posted on 14 Jan, 2013 12:10 AM

What happens when two or more states are dependent on same water resource for agricultural purposes ? Do the states compete for the resource or are their needs sufficiently different from each other? What are the consequences of the competition for this precious resource?

This article sheds light on the dispute between Karnataka and Tamil Nadu, for sharing Cauvery river water. The ongoing tussle between the two states has seen a lot of unrest amongst farmers in  form of dharnas, protests, rail roko and non-cooperation by citizens, and disagreement with the agreements made by their respective governments and unending negotiations by governments involved, to come to a mutually agreeable decision.

Evaluation of physico-chemical characteristics in groundwater using GIS – A case study of Chinnar sub-basin, Cauvery River, Tamil Nadu, India
This study uses GIS to assess the potability of groundwater and the spatial variation of groundwater parameters in Chinnar sub-basin, Tamil Nadu. Posted on 20 Jan, 2012 04:26 PM

The study found that the groundwater of the basin is extremely hard with total hardness, magnesium and potassium contents being above the permissible limits. Thirty nine out of 57 samples exceed the allowable limits for fluoride.

GIS based rainfall-runoff modeling for Hemavathy catchment – A research report by National Institute of Hydrology
The report deals with GIS based rainfall-runoff modeling using Topography Model for the Hemavathy catchment of Cauvery basin in Western Ghats of Karnataka. Posted on 29 Jul, 2010 09:19 PM

The report deals with Geographical Information Systems (GIS) based rainfall-runoff modeling using Topography Model (TOPMODEL) for the Hemavathy catchment of Cauvery basin in Western Ghats of Karnataka. The TOPMODEL is a variable contribution area model in which the predominant factors determining the formation of runoff are represented by the topography of the basin and a negative exponential law linking the transmissivity of the soil with the vertical distance from the ground level.

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. Posted on 26 Aug, 2009 04:23 PM

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.

Map: Location of water resource projects across river basins in India
This map from the National Institute of Hydrology shows the location of the various water resources projects in each river basin in the country. Posted on 20 Aug, 2009 03:23 PM

The map indicates that across the main 19 river basins of the country, water resource projects with a total live storage of 174 BCM (Billion Cubic Metres) have been completed, 75 BCM are ongoing, and 132 BCM are being planned.
