In last few days Chennai has been receiving all the blessings of Lord Indra. It's been pouring down continusouly there. All water reserviours like Puzhal Lake, Poondi Lake, Cooum River, Chembarambakkal lake, Adyar river are overflowing. Looking at this spectre we think nothing was in the hands of human beings and everything was nature's done. But it's only half picture. If we look at the role of man in making it severe we will come to know that it was mostly man made. So the reasons of roads becoming rivers and Chennai a water city are as follows:-
a) The main reason is mindless development of Chennai over last two decades.
b) Lowlands have been filled up and choking of stormwater drains and other exits for water were among the major role players in escalation of crisis.
c) Stormwater drains-the fundamental instrument of flood fightig-are supposed to be planned on the basis of topographical data and their linkage with water bodies was ignored by the city authorities.
d) Construction along the course of stormwater drains and design of roads have rarely been seen as part of a whole project of stormwater drains.
e) Construction was done without details on topography or flood character of sites. Even the water log data of last 10 years are often not considered. Contractors were hurry to complete works.
f) Illegal construction has been on such large scale that there are over 1.5 lakh illegal structures in the city according to the CMDA.
g) High court orders to demolish these constructions has not been followed as business houses and individuals got it stayed from supreme court.
h) Due to these illegal constructions more than 300 water bodies have disappeared.
i) Areas like Mudichur, Velachery have come up on wetlands or river basins resultantly flooded now.
j) Nothing learnt from major flood of 2005, Chennai commissioned a project to prepare laser terain maps, scanning the entire city from a helicopter but this project remains unimplemented.
These all points prove that it was a more man made flood than nature's created similar to srinagar's flood last year.
