A CASE STUDY TO INCREASE THE BENEFITS ON INTERLINKING OF PAR-TAPI-NARMADA LINK PROJECTR.K. Jain, Dulal Goldar and Rajesh GoyalAbstract The research is aimed to conduct critical analysis of project benefits, Irrigated area, quantum of water to be transferred and enhancement of benefits of one of interlinking project viz Par-Tapi-Narmada link basic genesis of feasibility level proposal of Par-Tapi-Narmada link. An attempt has been made to review the proposal at Feasibility Stage and suggest measures for improvement. The Par-Tapi-Narmada Link ILR proposal at Feasibility Stage (2005) was finalized with diversion of 1350 MCM of water out of which a major portion was used for supplementing Narmada Command and later use of saved water by substitution in Narmada Command of Saurashtra and Kutch. The cost of Rs. 60,164 Million was mainly for 7 Dams and 400 km long canal only. Thus, there was a need to optimize benefits by using better irrigation techniques. There is possibility of optimizing water utilization by reducing irrigation intensity in enroute command. Reduction of water can be done by deleting dams and B-C ratio can be increased from 1.08 to 1.29 as observed in various combinations. Therefore, there is need for re considering 7 dams in position and adopting 5 to 6 dams. An introduction of micro irrigation in the command area by switching over from gravity flow irrigation increases the Benefit Cost ratio of the project considerably. Also aspect of increasing water through Ukai Dam and maximization of crop yield are established. All these gives concrete shape to sustainability of Project. |
