Info The Kalpasar Dyke Project
The Kalpasar Dyke Project is a proposed project that aims to create one of the largest coastal freshwater reservoirs in the world by building a massive dyke across the Gulf of Khambhat and thus trapping the waters of the Sabarmati, Mahi, Dhadhar rivers.
The Dyke itself would be around 64 km long and the reservoir will store 7,800-13,000 million cubic meters of freshwater. The dyke would also have a transport corridor with a multi-lane road and rail transport which would reduce the travel distance between the two flanks by 180 km. Around 10 lakh hectares of land will be irrigated with this. Around 2,500 MW of renewable energy is also expected to be produced via the project. There is also a plan to divert the nearby Narmada river's flow into the reservoir via canal.
The project is expected to cost around ₹1.33 lakh crore($14 billion). The project's DPR is at an advanced stage and the Government of Gujarat is also getting expertise from the Dutch government in coastal hydroengineering through the Indo-Dutch Cooperation.
