New Delhi :
Indian Institute of Technology Madras (IIT Madras) researchers have studied floods in Chennai and have proposed the construction of ‘Straight Training Walls’ at the mouth of Ennore Creek in order to minimize the flood risk significantly on its upstream. The study focused on extreme storm surge scenarios and high tide levels along with flooding in the river. It found that heavy siltation in the creek mouth and narrow opening in the mouth posed a flood threat to the areas adjoining the river.
Alternative Proposal of Curved Training Walls –
The study showed straight training walls at the creek mouth and some regular de-silting of the river will improve the situation and minimize the flood risk significantly in North Chennai. It also showed that an alternative proposal of curved training walls proposed earlier will worsen the situation, by blocking the free exchange of Seawater with the creek, thereby, increasing the flood risk.
The researchers found that heavy siltation & narrow opening in the creek poses a flood threat to the city. 👏https://t.co/0u5fVGq1yB

Education Minister Ramesh Pokhriyal ‘Nishank’ tweeted,” The researchers found that heavy siltation & narrow opening in the creek poses a flood threat to the city.” Undoubtedly, it will gonna help minimize the floods in Chennai and it will help to make other projects like this too.
