Real-Time Flood Forecasting System Chennai enhances urban flood management using sensors and predictive analytics. Learn about the RTFF & SDSS, river coverage, and operational infrastructure.
Chennai Becomes First Indian City to Launch Real-Time Flood Forecasting System
In a significant advancement in urban disaster management, Chennai has become the first city in India to fully implement a Real-Time Flood Forecasting and Spatial Decision Support System (RTFF & SDSS). Operational since October 2025, this system enhances the city’s ability to predict, manage, and respond to urban floods, marking a milestone in climate resilience infrastructure.
What Is RTFF & SDSS?
The RTFF & SDSS is an advanced technological system that integrates real-time data to monitor and predict flood events. Key components include:
- Automatic Rain Gauges (ARGs): Measure rainfall intensity and distribution.
- Automatic Weather Stations (AWS): Monitor atmospheric parameters such as temperature, humidity, and wind speed.
- Automatic Water Level Recorders (AWLRs): Track water levels in rivers and lakes.
- Gate Sensors (GS): Control the opening and closing of sluice gates to manage water flow.
These tools collect high-resolution hydrometeorological data to inform decision-makers and local authorities.
Coverage and Geographic Scope
The system covers 4,974 sq km, including Chennai city and its surrounding districts. It focuses on important river sub-basins such as:
- Adyar River
- Cooum River
- Kosasthalaiyar River
- Kovalam River
This wide coverage allows authorities to identify vulnerable zones, forecast rainfall impacts, and take timely action.
Implementation and Funding
The RTFF & SDSS project was funded by the World Bank under the Project Development Grant Fund (PDGF) and implemented by Tamil Nadu Urban Infrastructure Financial Services Limited (TNUIFSL). It was developed in collaboration with:
- SECON Private Limited
- JBA Consulting (UK)
- Indian Institute of Technology Madras (IIT-M), which played a supervisory role, ensuring scientific integrity and technological robustness.
Operational Infrastructure and Management
The system is monitored and controlled via a central Hydro Modelling Control Room (HMCR) in Chennai. For on-ground flood response, Regional Control and Command Centres (RCCCs) have been set up in:
- Royapuram
- Anna Nagar
- Adyar
These centres use CCTV cameras, flood and rain sensors, and water level meters to enable real-time situational awareness and localized response strategies.

Model for Other Cities
Chennai’s initiative serves as a model for other cities facing similar flood risks. The RTFF & SDSS provides a scalable framework that can be adapted to different urban contexts, promoting widespread adoption of advanced flood forecasting systems across the country.
Historical Context
Previous Flooding Challenges
Chennai has faced significant flooding challenges in the past, particularly during the monsoon season. The city’s vulnerability to flooding is due to factors such as rapid urbanization, inadequate drainage systems, and the encroachment of water bodies.
Development of Flood Forecasting Systems
In response to these challenges, efforts have been made to develop and implement flood forecasting systems. The RTFF & SDSS is the culmination of years of research and development, involving collaboration between various stakeholders, including the Tamil Nadu government, IIT Madras, and international consultants.
Evolution of Flood Management Strategies
Over time, flood management strategies in Chennai have evolved from reactive measures to proactive approaches. The introduction of the RTFF & SDSS represents a shift towards data-driven decision-making, enabling authorities to anticipate and mitigate flood risks more effectively.
