Project on the “Design of an Expert System for Flood Forecasting and Management for the city of Chennai”

The city of Chennai experienced a major flood situation in 2015. Under O/o the PSA to GoI, an expert system is being developed for flood forecasting along with flood inundation maps and possible means of its management through appropriate interventions for dealing with any such future events. The objectives of the project are:

  1. Development of near real-time flood forecasting system along with visualization
  2. Flood Monitoring with Sensors
  3. Understanding the suitability of drainage networks and scope of improvements
  4. Flood/ water management (along with upstream reservoir operations based on forecasts, cleaning of urban rivers/ nallahs)

The design of the system involves coupling of regional weather forecast model, tide forecast model, tidal flood model, urban overland flow model, and stormwater drainage model. The proposed expert system is multi-disciplinary in nature with the involvement of multiple institutions and organizations. The Participation of Ministry of Water Resources and Ministry of Urban Development is also there.  The system is expected to be ready by April 2018. The real-time operational system will be set up at the Integrated Coastal and Marine Area Management (ICMAM) under the Ministry of Earth Sciences, in close coordination with Tamil Nadu local and state authorities.

It is planned that, after completion of this project, similar expert systems can be taken up in other urban areas like Mumbai.
