City Flood Alert – Overview
The City Flood Alert has been launched by the Andhra Pradesh government on 26 July 2026. The system uses artificial intelligence, satellite‑based terrain mapping, predictive analytics and hydrological modelling to forecast rainfall up to 48 hours ahead and flash‑flood warnings up to six hours ahead.
Key Developments
- Initial deployment in Vijayawada, a city prone to floods from the Budameru rivulet.
- Integration of a high‑resolution Digital Elevation Model created from satellite data and three decades of flood history.
- Automatic alerts sent to the APSDMA, which then informs District Collectors, Municipal Commissioners and field officials.
- Planned expansion to all urban local bodies across Andhra Pradesh after the pilot phase.
Important Facts
- Rainfall forecasts are generated up to 48 hours in advance.
- Flash‑flood warnings are issued up to six hours before a potential event.
- The platform can simulate inundation under different rainfall scenarios and identify drainage channels vulnerable to silt accumulation.
- Stakeholders include the RTGS, IIT Gandhinagar, and APSDMA.
