urban floods

Located in the southwestern suburbs of Chennai, the neighbourhood of Chitlapakkam had been prone to flooding only five years ago. About 20 centimetres of rain would cause severe inundation of houses and it was under the threat of sheet flooding of more than five feet of water, which would remain stagnant for around a week. The dream of making this locality flood-free seemed distant at the time but has now become a reality. Every monsoon, Chitlapakkam would get inundated as the town is sandwiched between the flood plains of Selaiyur lake and Chitlapakkam lake surplus. As a volunteer of the…

As Cyclone Michaung ripped through Chennai and surrounding areas, and news about localities getting inundated with heavy rainfall started coming in, and a few affected residents narrated their ordeal online. As the day wore on, there were many calls for rescue and relief from citizens stranded in waterlogged areas.   Meanwhile, a group of researchers from IIT Madras were doing their bit by giving real-time weather information on social media. They also urged people to record flood information in their localities on the chennaiwaterlogging.org portal. Their efforts seem to have paid off because as many as 1,200 users recorded the…

When Cyclone Michaung was wreaking havoc over different parts of Tamil Nadu on December 4th, with the heavy rain and squally winds battering Chennai and its suburbs, a small group of residents in Tambaram swung into action. Among the many stories of distress and wreckage, the efforts of these individuals to prevent floods in low-lying areas and to stop water from entering homes, while ensuring relief supplies to affected communities was heartening. Dr S M Govindarajan, Founder President of the United Federation of Residents Welfare Associations of Tambaram City Corporation narrates how flood control, rescue-and-relief work were taken up by…

There can be no dispute over the fact that the frequency, intensity and spread (new cities getting affected) of urban floods is increasing in India. The reasons are mostly known: increasing and mostly unplanned urbanisation, rural-urban migration, encroachments of water bodies, concretization of flood plains and other lands, decreasing capacity to hold, store, recharge and drain the rainwater, increasing rainfall intensities with changing climate, wrong operation of big dams and deteriorating governance. The damages are going up, also because our forecasts are far from reliable, accurate, location-specific or with sufficient lead time. Because of our incapacity to learn lessons. Disaster…

Hyderabad lay submerged under the highest ever rainfall since 2003. While the October average has seen around 103.6 mm, October 13th saw the skies discharge 192 mm of rain, followed by another deluge in and around Hyderabad on October 17th. Added to the pandemic, the heavy rainfall made an already bad situation for Hyderabadis much, much worse. Major roads and highways were severely damaged and several colonies were isolated from the rest of the city. Hundreds of families were unable to access basic needs like drinking water, food and power for over three days following the rainfall. About 80 colonies…

When temperatures soar, Delhiites pray for rain. But when it pours, even just for a few hours, tragedy strikes. As happened on July 19th. Severe waterlogging submerged many parts of the city creating huge traffic jams. One house collapsed when a drain near it collapsed, and four people died from the flooding in different parts of the city. Among the major casualties on the same day was the central dome of Delhi's iconic Mubarak Begum mosque -- built in 1823 and a prominent visitor attraction -- which collapsed in the torrential rain. Such monsoon mayhem has become an annual feature…

It is that time of the year again. When it rains, rather pours, in Mumbai ( the Mumbai region has the second highest rainfall in the country after Cheerapunji). And then the blame game begins to divert attention from the flooding of the city, loss of lives and livelihoods, and health issues.  Brihanmumai Municipal Commissioner (BMC) Iqbal Singh Chahal claims that the city is all set to meet the rains with its over 2900-km long storm water drain network -- all desilted and cleaned up, despite the COVID crisis and large-scale labour migration. Chahal announced that BMC has already surpassed…

The videos were all over the Internet and social media. Expectedly so, because you don't often see crocodiles swimming in flooded urban streets, sneaking up on strays. But that's precisely what happened shortly after news of ‘urban floods’ in Vadodara hit headlines in early August. The city witnessed scary flash floods following spells of intense rain, bringing back memories of what the city had witnessed in June 2005 and then again in the monsoon of 2014, the latter perhaps leading to the coinage of the phrase ‘urban floods’. Back in 2014, ecologists had spoken up to communicate their worries to…
