THE WOES OF TAMIL NADU CITY [GS I-Geography, GS III-Environment and Disaster Management]

THE WOES OF TAMIL NADU CITY [GS I-Geography, GS III-Environment and Disaster Management]

CONTEXT : As many as 5 people have been killed in rain-related incidents and over 1,400 moved to relief camps as the rainfall continued to strike parts of Tamil Nadu. The IMD predicted heavy to extremely heavy rainfall in parts of the TN on 9 and 10 November 2021, citing the low-pressure zone formation over the Bay of Bengal.

 In the last 4 days, other parts of the State also, were at the receiving end of the monsoon. Nagapattinam, one of the backward areas of the Cauvery delta, was devastated after 31 cm fall in a day.

  • The ongoing spell of heavy rain in Chennai has revealed its vulnerability to floods. 

  • The first spell of heavy rain of 21 cm, (November 7) has already surprised everyone.

Chennai is a coastal metropolis with a flat terrain as far as its geography is concerned.The issue of drainage is the main problem in Chennai or in Nagapattinam.


 There was a depression in the Bay of Bengal, which crossed the coast near Chennai on 11 November 2021 (Thursday). Chennai experienced very heavy rainfall but several suburbs like Tambaram and Red Hills recorded over 22 cm of rain.

In a large urban setting such as Chennai, there are the issues of :-

  •  The shrinking of open spaces

  •  The gap between the coverage of the drains and that of sewer lines

  •  Ageing drains and sewer networks in core areas of the city.

  •  Encroachments or obstructions hampering the free flow of water are responsible for the  mess. 


  • The city is blessed with a few rivers such as the Cooum and the Adyar, apart from a number of canals including the Buckingham Canal. 

  • All these available water bodies can be very effective flood carriers, if properly maintained.


  •  The State Government, executing a couple of integrated storm water drain projects, must devise some durable solutions to the city’s long-standing miseries and implement them in a shortest possible time.

  •  The Government has been very swift in providing relief and its seriousness in the matter.

  • Mr. Stalin, who was Chennai Mayor and Local Administration Minister earlier should use his experience and pull the city out of the dilemma. 

  • The Government has to hike its preparedness to deal with the northeast monsoon in advance with the retreat of South-West monsoon every year  

RESPONSIBILITY OF THE PEOPLE :- To fulfill their responsibility and ensure that the water bodies and drains are not turned into dumps. Though much needed improvement has not been seen in the problem of inundation from years.
