Making large campuses resilient to heavy rain
The Hindu
‘RWH structure should be installed based on soil profile’
With the intense spell of rain like the one witnessed in November likely to become a frequent phenomenon owing to climate change, experts stressed on the need to make large open spaces more resilient to floods.
Shilesh Hariharan, principal architect at Madras Terrace, who is associated with the City of Thousand Tanks initiative, said installation and strengthening of rainwater harvesting and recharge wells must be done based on soil profile on campuses.
He said it was important to identify the region of clay, the region of sand and so on to make the percolation of water efficient. Regular maintenance of rainwater harvesting structures prior to monsoons was important.
When fed into Latin, pusilla comes out denoting “very small”. The Baillon’s crake can be missed in the field, when it is at a distance, as the magnification of the human eye is woefully short of what it takes to pick up this tiny creature. The other factor is the Baillon’s crake’s predisposition to present less of itself: it moves about furtively and slides into the reeds at the slightest suspicion of being noticed. But if you are keen on observing the Baillon’s crake or the ruddy breasted crake in the field, in Chennai, this would be the best time to put in efforts towards that end. These birds live amidst reeds, the bulrushes, which are likely to lose their density now as they would shrivel and go brown, leaving wide gaps, thereby reducing the cover for these tiddly birds to stay inscrutable.
