"Prayagraj, the city on the banks of the Holy Ganga, witnesses large gatherings every 12 years during Maha Kumbh. The location witnesses the merging (or Sangam) of Holy Ganga and Yamuna, and the Sangam area is considered highly auspicious. The pilgrims expect an opportunity for a holy dip in the River Ganga during the Maha Kumbh occasion. However, River Ganga was in extremely braided conditions in Feb-2024 at Prayagraj with water levels far below for any possibilities of holy dips. This situation prompted the Mela Authority, Prayagraj, to seek expert advice in channelling the river flow of the Ganga at Prayagraj. The Mela Authority consulted IIT Guwahati for a possible solution to the same and Prof. Rajib Bhattacharjya and Prof. Suresh Kartha from the Centre for Sustainable Water Research formed a team to work on suggesting river training mechanisms to channelling the river flow. The team performed hydraulic modeling to identify the possible pathways and vulnerable locations in the river stretch and further simulated suitable training measures from the upstream Phaphamau bridge to downstream Chatnag Ghat. The team was in frequent discussions with the Mela Authority and Irrigation Department of Govt. of Uttar Pradesh and suggested timelines to implement appropriate measures. The training work involved pre-monsoon and post-monsoon measures on River Ganga so as to ensure the stability in its pathway. Some of the important measures suggested by the team involved - the incorporation of multi-layered geo grid filling at Sangam Nose, dredging of River Ganga from Shastri Bridge to Sangam Nose, the tube cutters as groins at intermittent intervals from Shastri Bridge to Sangam Nose, etc. The recommendations from the IIT Guwahati team were subsequently implemented by the Irrigation Department, Uttar Pradesh, and the works are showing fruits as the river has channelized in the important Sangam Nose area for the Maha Kumb event."
