Answers
2017 Mumbai flood refers to the flooding that occurred on 29 August 2017 following heavy rain on 29 August 2017 in Mumbai. Transport systems were unavailable through parts of the city as trains and roadways were shut. Power was shut off from various parts of the city to prevent electrocution.[1] The International Federation of Red Cross and Red Crescent Societies (IFRC) called the South Asian floods one of the worst regional humanitarian crises in years.[2] This event can be compared with the 2005 floods in Mumbai, which recorded 944 mm (37.17 inches) of rainfall within 24 hours on 26 July.
The extreme rainfall on 29 August 2017 was forecasted by the Indian Meteorological Department (IMD), five to six days in advance. However, the government failed to respond quickly, leading to the crisis.Recent research indicates that these floods could be attributed to climate change. Climate change has led to huge fluctuations in the monsoon winds carrying the moisture from the Arabian Sea, resulting in heavy rainfall over central India, lasting for two to three days.
Answer:
The average rainfall of Mumbai is around 940 mm, and of late it is increasing due to global warming and environmental change and flooding the city.
The main reason of the floods in Mumbai is clogged drains, use of excessive plastics that block the drains and the siltation of the Mithi River which is one of the major outlets to drain out the rainwater.
