I guess the annual release of 192 TMC by KA was arrived at right calculations and not any political lobbying. But is this release on all years? (I mean drought years too?) Being the home of Mathematical geniuses (India), 192 TMC per year may have been arrived correctly. Also due to political/skewed up Indian mind, it may be incorrect too. But, from my limited knowledge of numbers, it comes out that KA should release135 TMC per yr.
My calculations: For the sake of simplicity, removed Kerala and Pondicherry.
Assuming, basin area in TN is 43 SqKm (57%) and KA is 33 SqKm (43%) and water collected by TN is 250 TMC and KA is 425 TMC. (Total of 675). TN should get 385 TMC (57% of 675) and KA should get 290 TMC (43% of 675). Since TN is collecting only 250 (because of the upper dams- kabini, KRS, etc.), it should get (385-250) which is 135 TMC. And KA is collecting more 425 (instead of 290), it should release 425-290=135 TMC. This, only if 675 TMC is collected in a given year. If it is less or more then 675 TMC, it should be proportionate. Both regions should be proportionately drought or flooded. Ofcourse, both parties may argue on these numbers. But is it rocket science to get the actual numbers from the area? We know where the river flows and just get the catchments area around the river? Ofcourse, there may be other subtleties to these calculations. I am open to change these numbers.

your calculation ir right except for one thing. the 250 that TN collects does not serve the upper western portion of TN because the rain and collection is downstream. When you taken this into account and make it more accurate, the number comes closer to 192. In fact, this number of 192 is less than what Karnataka has been releasing all this time of 205. Karnataka should be happy because now they release less than in 2005, etc. TN should be happy because now, they can plan their agri industry better.
When there is drought, everybody takes a percentage hit. In otherwords, if water is 10% less overall, then TN gets 10% less, Kar 10% less, etc.
This is actually a disadvantage for north western TN. So for example, if Kar gets 270tmc of rain (this is a drought) and TN get 419 in lower easter portion. Then the commission says that TN has enought water, hence Kar can keep 270tmc. This means that upper western region of TN gets no water as neither Kar will release water or TN can pump water to north western region of TN. At the end, no matter what Indians suffer.
I am neither from TN or Kar but interested in the scientific method. This commission was also called by Karnataka and agreed by TN. They both have the right to appeal but must abide by the ruling until the appeal is successful and not make this into an inter-ethnic war.

The key is releasing waters during summer. KA release 205 tmc, out of which mostly were on rainy season Tamil nadu could not use that much water and mostly ends up in the sea. In fact that has caused lot of damages to the crops. [ you might guess why can't TN store those waters ? but limitage of Dam storage restricts that ].
so the key in the tribunal's award is sharing-of-water during needy times. I think it is much better. TN is not getting more water than before, but it can get more water during summer and can plan better than before.

posting again !! RE:RE:Rocket Science!? by mj on Feb 07, 2007 02:49 AM | Hide message Interested in scientific method? eh. Well then, consider this. Tamil Nadu has nearly 100 tmc worth of ground water sources the it has not touched while Ktaka has next to nothing. 2/3rd of the basin area in Ktaka is drought prone whereas only 1/4th of the basin area in TN is drought prone. So Ktaka has even more pressing need for water for irrigation. And then distress sharing. How convenient of you to say take the 'average distress'. So, do you mean if there is a 50% shortfall in rainfall in Karnataka to 10% shortfall in TN, Ktaka still has release water as if its only facing 30% shortfall? And then, apart from the ground water sources in TN, who is to count the North East monsoon that feeds the Kaveri in TN but not in Ktaka. Ktaka only has one monsoon season. TN has two. So that is all the more reason for Ktaka to store water for pre and post monsoon periods. Finally, TN's numero uno argument all along has been that, even though they've developed 28 lakh acres against the letter and spirit of the past agreements, they should be given amnesty simply because cutting off supplies to the 'illegaly' expanded portions would mean rendering millions jobless. This is a patently silly, absurd and atrocious argument. It is neither Ktaka's moral obligation nor legal binding that it has to feed every sq inch of TN's millions of acres. These figures sum it up: Karnataka irrigates 11.2 lakh acres and one crop per year TN irrigates 28 lakh acres and upto three crops a year.
Like Gandhi says, "There's enough for everyone's need, not for someone's greed". Shame on wretched tamilians and their politicians. No wonder with all the water and everything they're still a cursed and wretched lot.
