BENGALURU: In a meeting held at its headquarters in Bengaluru on Tuesday, Suresh Gopi, Union Minister of State for Petroleum and Natural Gas & Tourism, sought Isro’s support to evaluate the flood risk associated with the Mullaperiyar and Idukki dams in Kerala, the space agency said Wednesday.
Expressing concern over the increasing incidents of extreme weather events, Gopi stressed the urgent need to assess the worst-case flood scenario linked to these dams.Isro chairman S Somanath, assured of support in providing space technology-based inputs, such as high-resolution terrain data, to researchers engaged in flood modelling.
Somanath suggested developing a prototype solution integrating flood risk analysis with rescue and rehabilitation planning, along with satellite communication capabilities. He also emphasised the importance of capacity building on the role of space-based support for disaster management.
During the meeting, Prof Jaison Paul Mulerikkal from Rajagiri School of Engineering & Technology, Kochi highlighted the requirement for very high-resolution terrain data, as publicly available data is insufficient for their ongoing research on flood risk modelling in the Periyar river basin.
Sunil Paul from Christ College of Engineering in Ernakulam briefed about the development of a remotely operated solution for bathymetric survey and siltation assessment in dams. Gopi also stressed the need to study the extent and nature of siltation in the dams and evaluate the possible utilisation of the sludge to support local industries.
Prakash Chauhan, director, Isro’s National Remote Sensing Centre and his team presented the spatial flood early warning system developed for the Godavari and Tapi rivers, which utilises high-resolution ALTM-based digital elevation data and reservoir sedimentation studies.
The team from Rajagiri School of Engineering & Technology plans to visit NRSC for further discussions on leveraging Isro’s expertise and capabilities for their flood risk modelling efforts in Kerala.
