Dredging and excavation work is currently underway along the southern bank of the Brahmaputra River in Guwahati, officials have confirmed. The exercise aims to balance river depth between the northern and southern sides, as the northern bank is presently deeper.
Authorities stated that the project also includes strengthening the southern embankment to reduce flood risks during the monsoon.
Dredging work is underway along the southern bank of the Brahmaputra in Guwahati to balance river depth with the northern side. Officials said the project will link a new channel to the Bharalu River and reinforce the southern embankment with protective measures to help mitigate flooding during the monsoon.
Why the Dredging Is Being Done
According to officials, the northern side of the Brahmaputra in Guwahati is currently deeper than the southern bank. The dredging and excavation are intended to create a more uniform depth across both sides.
An official stated that the channel formed after dredging will be connected to the Bharalu River, which flows through central Guwahati. The linkage is expected to improve water flow and drainage.
Strengthening the Southern Embankment
Alongside dredging, the southern embankment is being reinforced to mitigate flooding. Officials said porcupine structures will be placed to strengthen vulnerable sections of the bank.
Porcupines are commonly used river training structures designed to reduce erosion and stabilise embankments during high water levels.
Work Being Carried Out in Phases
Construction and reinforcement are being undertaken in phases, focusing first on stretches identified as erosion-prone or vulnerable to flooding.
Authorities have stated that safety protocols are in place to minimise disruption to nearby communities and river traffic.
Why This Matters for Guwahati
The Brahmaputra plays a central role in Guwahati’s geography and flood dynamics. Uneven river depth and weakened embankments can increase the risk of overflow during heavy rainfall.
By balancing river depth and strengthening embankments, the project is aimed at enhancing flood resilience in low-lying areas of the city during the monsoon season.
What Happens Next?
Dredging and embankment reinforcement will continue in phases over the coming weeks. Authorities are expected to monitor the river’s flow and structural stability ahead of peak monsoon conditions.
The initiative forms part of broader river management measures being undertaken to improve long-term flood mitigation in Guwahati.
Frequently Asked Questions
Q1. Why is dredging being done on the Brahmaputra in Guwahati?
Dredging is being carried out to balance the river depth between the northern and southern banks and improve water flow.
Q2. How will this help reduce flooding?
The project includes reinforcing the southern embankment and improving drainage by linking a new channel to the Bharalu River, which may help manage excess water during the monsoon.
Q3. What are porcupines in river management?
Porcupines are protective river training structures used to reduce erosion and stabilise embankments.
