Issue

Maharashtra’s Chief Minister Uddhav Thackeray and Union Minister for Health and Family Welfare, Science and Technology, Dr Harsh Vardhan launched an Integrated Flood Warning System called ‘IFLOWS-Mumbai’.

 

Background

Mumbai is only the second city in the country after Chennai to get this system. Similar systems are being developed for Bengaluru and Kolkata.

 

Details

  • A joint initiative between the Ministry of Earth Sciences (MoES) and Brihanmumbai Municipal Corporation (BMC), the warning system will be able to relay alerts of possible flood-prone areas anywhere between six to 72 hours in advance.

  • 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.

  • 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 primary source for the system is the amount of rainfall, but with Mumbai being a coastal city, the system also factors in tidal waves and storm tides for its flood assessments.

  • 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.

  • Based on the amount of rain recorded, time, location, topography and forecast, the system is designed to generate flood warnings for specific geographical areas of the city. 

  • 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.

  • Urban flooding is common in the city from June to September, resulting in the crippling of traffic, railways and airlines. As 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.
