The Coromandel Floods 2015


NORTH-EAST MONSOON 2015 WAS DISAPPOINTING??

(A Write up by Sai Krishna)


1) Highlights of The Topic:

A) There Was a Very Scanty Amount of NE Monsoon Rainfall in OCT (less than 6 cm) The Others  

Came From The First Week Rains .Which Can Be Called Officially As NEM, but the month of  

October was a failure.
B) A Huge Amount Of Rainfall in A Span Of 30 Days Almost 150+ Cm fell In Many Places with 

Most Of The Spells Being very Intense and Not Being Spread Evenly Which ultimately Caused 

"The 2015 SOUTH INDIAN FLOODS".
 


C) The Monsoon Had Been A Exciting Monsoon For The Weather Enthusiasts But A Horrifying and  
Sad Monsoon For The Common Tamil Nadu People.



D) Almost 50% Of The Water From The Rains Had Not Been Stored. The Waters Were Wasted Into  

The Sea Which Resulted Water Problems Even After These Deluges. AS THE RAINS WERE'NT 

EVENLY SPREAD. 

AS A RESULT CHENNAI WAS FLOATING UNDER FLOODS WITH ALMOST 10 LAKH  
PEOPLE SUFFERING. --------------------------------------------------------------------------------------------------------------------------------------------- 2) " A GOOD LESSON GIVEN BY THE MONSOON TO THE PEOPLE" A) Restoring HUMANITY. b) Also Taught That Money Is Nothing and Humans Influence is The Best. c) All Rich and Poor are Equal in Front Of Nature.

--------------------------------------------------------------------------------------------------------------------------------------------- 3) This Monsoon is Not even Near 2005 Monsoon which Was the Best Monsoon For Chennai and  

Tamil Nadu 2005 Is a Monsoon which needs to Be remembered. The Rains Were Evenly Spread  

Unlike 2015. Places Of Chennai Experienced Floods in 2005 But Not Like What We Experienced  
This Monsoon. Chennai Received A Total Of 211 cm in The NEM in 2005. But There Weren't 

These Intense Floods.

--------------------------------------------------------------------------------------------------------------------------------------------- 4) A Full Report on Chennai's Floods in 2015. Cuddalore, Chennai, Kanchipuram and Thiruvallur are worst-affected districts. Here are some  

numerical facts with dates:
Oct 28, 2015: North-East monsoon entered Tamil Nadu.
Nov 8, 2015: Low pressure developed into A Deep Depression in Bay of Bengal, that led to heavy  

rains.
Nov 15,2015: Another Low Pressure Led to Very Heavy Rains Of Above 200mm+
Dec 1, 2015: Heavy downpour started that continued intermittently till Wednesday,
Dec 30, 2015: From 8.30 am on Dec 1 to 8.30 am on Dec 2, 330 mm rainfall was recored. From 

Nagapattinam to Cuddalore, rainfall from 45 mm to 133 mm was recorded.

-As per the IMD department, 100 mm rains are likely to occur for next 2 days. 40% mobile and 20%  

landline connections are disrupted.
-So far, the death toll has been recorded as 269 in Tamil Nadu, 54 in Andhra Pradesh and 2 in  

Puducherry.


Rescue operations

a) 28 teams of NDRF with 944 personnel and 102 boats have been deployed.
b) 7 teams of 434 army personnels are deployed to carry out relief and rescue work.
c) Till now, 40,432 people have been successfully evacuated. In Puducherry,
d) 2 teams of NDRF including 70 workers and 8 boats have been deployed. In Andhra Pradesh,
e) 6 teams of NDRF including 211 workers and 21 boats have been deployed.

Between 9–10 November 2015,

Neyveli received 483 mm (19.0 in) of rainfall and rains continued to lash Cuddalore, Chidambaram 

and Chennai.. Tirumala, the place in interior got over 300mm of rainfall. Continuous rains led to low-

lying parts of Chennai becoming inundated by 13 November, resulting in the evacuation of over 

1000 people from their homes.


"The flooding in Chennai city was worsened by years of illegal development and inadequate levels of flood preparedness".

Much of the city remained flooded on 17 November, though rainfall had largely ceased. 
Chennai received 1,049 mm (41.3 in) of rainfall in November, the highest recorded since November 1918.
When 1,088 mm (42.8 in) of rainfall was recorded in 2005, The flooding in Chennai city was described as the worst in a century. Rain poured like a monster that time.
The continued rains led to schools and colleges remaining closed across Puducherry and Chennai, 

Kancheepuram and Tiruvallur districts in Tamil Nadu and fishermen were warned against sailing 

because of high waters and rough seas.
Reason behind the floods??

Elnino, the season changer in most of the parts of world, is one of the responsible factor for such a 

severity of floods in chennai region.
Sea-Surface Temperatures


The sea-surface temperature in Bay of Bengal remained at a good potential and provided "More-than 

Normal Moisture" to the systems like 96B and 97B, which caused heavy torrential rainfall over 

chennai.

5) Why Chennai is Suffering In Water Crisis Even After Such Heavy Rains?


After December 7th - 2015,Chennai Hasn't A Received Even 2 mm Of Rainfall Till May -1st (2016)
and Also The Lack Of Water Storage Plans Has Lead To A Disappointing Monsoon in Terms Of 

People Suffering In Water and Also Suffering For Water After a 100 Days. There is No Need To 

Blame The Government.  Any Government In The World Would Have Failed Controlling 150 CM 

in 30 Days. The People Are To Be Blamed For Constructing In Illegal Places Of The Adyar Rivers.

Velachery,a residential area next to Pallikaranai marshland, gets flooded almost every November and 

was among the worst affected this year too. Wetlands are important as they help reduce the impact of 

storm damage and flooding, but these are fast shrinking.
“Some 40 years ago, Pallikaranai was a 50 sq. km marshland and now it has been reduced to a tenth 

of its size. 90% of the marshland is lost to construction of IT corridors, gated community, garbage 

dump, sewage treatment plant, etc,” said Jayaraman. Shekhar pointed out other areas, including 

MRC Nagar, built on the Adyar estuary, the Mass Rapid Transit System, built almost wholly on the 

Buckingham canal, Koyambedu Bus Terminal, the expressway and buildings on the Old 

Mahabalipuram Road, that are examples of blatant encroachments on waterways and water bodies.

"We require more than just good infrastructure. It will require good data and maps, sound planning 

practices and enhanced accountability of public agencies that are responsible for the way our city is 

shaped,” concluded Shekhar. Improper design and maintenance of drainage systems Media reports stated the Chennai Corporation had ignored September warnings of above-average 

monsoonal rains issued by the Indian Meteorological Department and that extensive and costly 

projects begun in 2013 to desilt city storm drains had been ineffectively conducted. The drains 

themselves were reported to have been shoddily built and improperly designed. A 2014 CAG report 

revealed that a diversion channel from the Buckingham canal near Okkiyum Maduvu to the sea (a 

drain project under the JNNURM scheme) could have saved South Chennai from flooding;
the government, however, dropped the 100 crore scheme, which, had it been completed, would have 

drained floodwater from southern neighbourhood at a rate of 3,500 cubic feet per second.
The 2014 CAG report said the defective planning of flood control projects caused delays and 

increased costs, defeating the objective of the scheme. "The fact is that alleviation of inundation of 

flood water in Chennai city remains largely unachieved"

1)Almost More Than a 100+ People Have Officially Died in Tamil Nadu During The Period From 

NOV 1 to Dec 5.
2)More than A 400 People Have Died and Almost A 50,000 People Lost Their Homes and 10 Lakh 

People Were Affected By these Floods.

3)When There is More Than 10,00,000 Lakh People Devastated By Floods Who Can it Be called As 

An Good Monsoon..???
