Perspective: Urban Deluge

In this episode of the Perspective Prog. based on Urban Deluge. Several parts in Chennai and its suburban areas reported waterlogging on Sunday morning after heavy rains lashed the city. The showers have now been marked as the heaviest downpour since 2015 with Met department predicted very heavy rainfall for 14 districts of Tamil Nadu, including Chennai, in the next two days. In fact there has been an increasing trend of urban flood disasters in India over the past several years whereby major cities in India have been severely affected. Some of the most notable amongst them are Hyderabad in 2000 & 2020, Ahmedabad in 2001 & 2020, Delhi in 2002, 2003, 2009 & 2010, Chennai in 2004 & 2015, Mumbai in 2005, Surat in 2006, Kolkata in 2007 and Srinagar in 2014. Urban flooding is significantly different from rural flooding as urbanization leads to developed catchments, which increases the flood peaks from 1.8 to 8 times and flood volumes by up to 6 times. Consequently, flooding occurs very quickly due to faster flow times. Urban areas are densely populated and people living in vulnerable areas suffer due to flooding and the secondary effect of exposure to infection also has its toll in terms of human suffering, loss of livelihood and in extreme cases, loss of life. Increasing trend of urban flooding is a universal phenomenon and poses a great challenge to urban planners the world over. According to a recent report on Urban planning capacity in India by NITI Aayog Urban planning has not received adequate attention and 65% of the 7933 urban settlements do not have any master plan.
