Sir, Well said.
I have already posted few articles of retired Senior IPS Officer of the Rank of DGP and a Senior IAS Officer among other articles to substantiate the stand that this was nearly a ‘Man made disaster’.
And in this regard, I would like to share an article published in today’s 'Times of India' which is self-explanatory.

Man made calamity: Humanitarian crisis caused by floods in Chennai could have largely been prevented
As Chennai emerges from the worst floods it has seen in over a hundred years, the sordid saga of how heavy rain turned the city into a disaster zone is slowly unfolding. There is no questioning the fact that such a quantum of rain can cause havoc in any city, particularly those with lowlands. But the catastrophe Chennai faced went beyond this.
Water release from the brimming Chembarambakkam reservoir on the city’s outskirts made this calamity a major tragedy. Record rain in mid-November had exposed the abysmal state of the city’s infrastructure. Even as the city was getting back on its feet, weather agencies predicted 500mm of rain on December 1-2. So government and the civic agency did have time to plan, but got entangled in red tape instead. It has come to light that PWD officials had advised higher-ups to bring down the reservoir level from 22 to 18 feet to make room for anticipated inflow. But this was ignored and sluice gates were opened when the reservoir reached its capacity of 24 feet. This water then spread out all over the city, flooding even areas largely unaffected by the heavy rain.

All these are postmortem..In case Chennai had rains for 1 more day with additional rainfall of 500 mm, it would have got drowned..The question of whether they opened or not opened sluice gates 4 days in advance would not arise then because Chennai does not have a mechanism to withstand such heavy downpour...Urban planners should plan for such an eventuality...Disaster planning is a must & these professionals will be in high demand now.
