The Vadodara Municipal Corporation (VMC) has initiated the construction of gabion walls along erosion-prone stretches of the Vishwamitri river in the city, following significant damage observed during recent floods. These protective structures will be erected near bridges and sensitive spots on the riverbank across the city.
Urgent Need for Erosion Control
Civic officials stated that the work became imperative after erosion was reported at several points along the river during the 2024 floods and again last year. The urgency escalated when erosion was detected near the Sayajibaug zoo, prompting the VMC to take emergency action under the Gujarat Provincial Municipal Corporations Act. The erosion had begun encroaching upon zoo land, raising concerns about structural safety.
Project Scope and Budget
The VMC plans to build gabion walls at 12 bridges and 12 other locations across the city. The total estimated expenditure for the project is Rs 89 crore, with Rs 36 crore specifically allocated for the gabion walls. An official confirmed that the work is being carried out on an emergency basis to prevent further damage.
In addition to the stretch near Sayajibaug zoo, construction has commenced near the Navlakhi artificial pond and at three bridges: Chetak Bridge, Mangal Pandey Bridge, and Urmi Bridge. All three bridges are located in the Sama area. Gabion walls are being planned around these bridges to protect their piles from erosion-induced damage.
Expert Recommendations and Activist Concerns
Experts had recommended the construction of gabion walls after the floods, particularly along stretches where erosion had worsened. In some areas, the loss of green cover on the riverbanks during floods, followed by dredging to reshape the river, had further weakened the banks. Activists had also raised concerns about the erosion and suggested gabion walls as a preventive measure, officials noted.
The gabion walls are designed to absorb the impact of flowing water and prevent soil erosion, thereby stabilizing the riverbanks. The VMC aims to complete the project swiftly to mitigate future flood risks and protect infrastructure.
