'We should plan for one Tsunami every 100 years'
New Indian ExpressIn 1802, Madras was the epicentre of a project that eventually led to the discovery that Mount Everest was the tallest peak in the world. The canal, which is about 800 km long from Kakinada in Andhra Pradesh to Chidambaram, and Kosasthalaiyar, Cooum and Adyar rivers that run through the city are a reminder of how Chennai is geographically endowed with waterbodies that have the capacity and capability to act as a natural protector against tsunamis, cyclones and carry excess flood water into the sea. The city is faced with unique quandaries- chronic water shortage, excess rain leading to flood and poor sewage treatment, translating into the death of its rivers. Firstly, the city requires a 3D map of its stormwater drains to know exactly where the excess flood water goes. We must also remember that the city is prone to cyclones and needs to plan for one Tsunami every 100 years, given our experience with Poompuhar and Seven Pagodas.
