Explanation:

Ministry of Earth Sciences (MoES) in coordination with Municipal Corporation of Greater Mumbai developed an Integrated Flood Warning System for Mumbai called ‘IFLOWS-Mumbai’.

1. IFLOWS-Mumbai is a state of art Integrated Flood Warning system for Mumbai to enhance the resilience of the city of Mumbai by making it possible to have an estimate of the flood inundation three days in advance, along with immediate weather updates.
2. It will provide early warning for flooding specially during high rainfall events and cyclones which would include alerts on rainfall information, tide levels, storm surge for low-lying areas anticipated to be affected. 
3. It is built on a modular structure comprised of seven modules, namely Data Assimilation, Flood, Inundation, Vulnerability, Risk, Dissemination Module and GIS based Decision Support System. 
4. The system incorporates
   - weather models from National Centre for medium Range Weather Forecasting (NCMRWF), India Meteorological Department (IMD),
   - field data from the rain gauge network stations setup by Indian Institute of Tropical Meteorology (IITM), Municipal Corporation of Greater Mumbai (MCGM) and IMD,
   - thematic layers on land use, infrastructure etc provided by MCGM. 
5. Mumbai is the second city after Chennai to get this system. Similar systems are being developed for Bengaluru and Kolkata. 
6. These systems are significant since many Indian cities like Mumbai, Chennai, Delhi, Kolkata etc. have been experiencing urban flooding with increased periodicity
