The Farakka Barrage Project on river Ganga, commissioned in the year 1975, mainly for diversion of 1135 cumec flow of water from river Ganga to river Hoogly through Bhagirathi, for the preservation of Kolkata Port. River Ganga due to its meandering nature is causing bank erosion problems not only in the vicinity of barrage but also in the reaches for upstream and downstream of the barrage.
