|“IFLOWS-Mumbai”-FLOOD WARNING SYSTEM FOR MUMBAI|
- IFLOWS-Mumbai is developed as a state of art Integrated Flood Warning system for Mumbai to enhance the resilience of Mumbai by providing early warning for flooding especially during high rainfall events and cyclones.
- IFLOWS is a monitoring and flood warning system that will be able to relay alerts of possible flood-prone areas anywhere between six to 72 hours in advance.
- Mumbai is the second city only after Chennai to get this system.
- Similarly, the system will be developed for Bengaluru and Kolkata.
|Ministry and Departments involved|
- Ministry of Earth Sciences, in close coordination with Municipal Corporation of Greater Mumbai
- Other Participants:
- The system incorporates weather models from the National Centre for Medium-Range Weather Forecasting (NCMRWF), India Meteorological Department (IMD), field data from the rain gauge network of 165 stations set up by Indian Institute of Tropical Meteorology (IITM), and BMC.
|How will it work?|
- The system can provide all information regarding possible flood-prone areas, likely height the floodwater could attain, location-wise problem areas across all 24 wards, and calculate the vulnerability and risk of elements exposed to flood.
- The system has provisions to capture the urban drainage within the city and predict the areas of flooding. The system comprises seven modules- Data Assimilation, Flood, Inundation, Vulnerability, Risk, Dissemination Module, and Decision Support System.
- The system has provisions to capture the urban drainage within the city and predict the areas of flooding.
|Why was this system needed in Mumbai?|
- Urban flooding is common in the city from June to September, resulting in the crippling of traffic, railways, and airlines. As a preparedness for floods before they occur, the system will help in warning the citizens so that they can be prepared in advance for flooding conditions.
- The recent flood on 29 August 2017 had brought the city to a standstill. Last year, post-monsoon and unseasonal rainfall as late as October, two tropical cyclones in the Arabian Sea had caught authorities off guard and left a trail of destruction.
- All this information will then be routed to authorities.
- The early warning forecast would include alerts on rainfall information, tide levels, storm surge for low-lying areas anticipated to be affected, thereby minimizing the damage from cyclones and heavy rain events in Mumbai by evacuating people to safe areas.
- The system, initially only to be accessed by the civic body will enable them to issue alerts for citizens who can then avoid such zones.
- According to the ‘Global Report on Internal Displacement 2020’, nearly 5 million people were displaced in India in 2019 because of disasters related to southwest monsoon and cyclones.
