The Hugli (Hooghly) river in northeastern India is an arm of the Ganges river formed at the junction of the Bhagirathi and Jalangi rivers, 250 km north of the Bay of Bengal, near the town of Navadwip. The river is bordered by the most heavily industrialized population of Bengal, and as such, is an important route for transport shipping.
But the onrush of the tidal bore on spring tides is a constant threat to this shipping and no doubt, has caused much destruction to unsuspecting navigators. The effects of the Hugli bore have been constrained since the construction of the Farakka Barrage, which has substantially reduced the frequency and severity of the bore.
