Kolkata Municipal Corporation has installed AI-equipped flood barrier gates along low-lying canals prone to overflow. These gates close automatically during high tide or heavy rainfall based on sensor input. Solar panels power gate motors and sensors. In a recent monsoon, automatic closure prevented canal backflow into residential areas, sparing flooding in 12 neighborhoods. The system reduced manual intervention and response time. Municipal engineers are expanding deployment to 30 more canals and integrating alerts into city disaster management apps.
