Chennai needs integrated flood management especially the revival of lakes and water tanks.
Chennai's date with a strong northeast monsoon ought to be a cause for all-round relief since the water fortunes of more than eight million residents of the metropolitan region depend on this weather system.Yet the terrential rains in the metrological sub -division,exceeding the normal by 93 % in the period of four days from November 1,left tens of thousands of citizens in state of despair.Flood water marooned them in the rapidly growing suburban housing clusters, with many having to flee to safter places fearing repeat of the deluge of 2015.While there have been efforts to alleviate immediate misery through the distribution of relief material in some places,the largest issue of how the city deals with flood and drought cycles remains unaddressed.Chennai is a lower elevation coastal city with global aspirations, and very high population density.Scientific management should have ensured the preservation of the many traditional lakes and canals that existed in the city's core a century ago to absorb the intense downpour of aairf.bout 1300 mm of rain,most of it in an annual window of a few weeks.Successive governments have allowed the mindless draining of wetlands and their convention into air.
