IIT Madras was sought to protect the island from the impending doom. The IIT team was asked to enable the rehabilitation of coral reef, while also reducing the erosion on the island. The IIT Madras research team then used “9,000 small units of reinforced concrete structure with holes” according to the paper. The concrete structures were being used for reviving an island for the first time in the world.
The team led by the Head of Department of Ocean Engineering at IIT Madras – Prof S A Sannasiraj, worked with Tuticorin based Suganthi Devadason Marine Research Institute to build and study small scale models and accordingly strategize the rehabilitation.
