This is why I am against river linking. It might bring water to the dry land, but it is going to drastically change the landscape and ecology of the country. Yamuna is like a dried up drain, Kaveri has not a drop to spare, Calcutta port is endangered by the lack of water supply.
Already there is no river/water channel which can boast of having excess water, How can government plan to achieve the redistribution?
In a country where it is impossible to construct a wall/dam on the riverbed…. How is government planning to acquire large tracks of land to link rivers and get funds to do the massive earthworks.
Then for the project to be economically feasible, water should flow in the linkage channels by gravity and not against it. No matter how attractive the project looks, it is going to to be a civil engineering nightmare to get this gradient correct.
