Point number 1: Length of the river does not include artificial channels.(Whether miles or Kms,the distance does not change).From Talakaveri to Hogenakal,the river Kaveri travels 320 KMs and this distance does not include the 116kms of an artificial channel that takes the water to Mandya from Madadkatte.Even a simple calculation of distances would show you that.
Point number 2: If you have a certain cultivated land,you cannot restrict others to the cultivated land that they have,they should be allowed to cultivate as much as they can(using the legitimate water resources that they should get).
Point Number 3 : The legitimate water resources are calculated using the yield,where Karnataka scores over Tamil Nadu(53% to 32%).
