Flood mapping not complete yet; no way to identify waterlogged areas


Minnu Venugopal

Though the government claimed that flood mapping was complete, only the marks made by the people during flood are remaining at many places.

Kochi: The government continues to be negligent in taking precautions despite the flood threat in the state. Though the expert committee advised to start flood mapping to find out the flood-prone areas and to start taking precautions, no action was taken in this regard.

The second phase of the flood mapping which started after the 2018 flood havoc has not been completed. It was directed to mark the areas flooded last year and to inform the public what steps need to be taken ahead of the monsoon. However, no action was taken even after heavy rain alerts were issued.

Though the government claimed that flood mapping was complete, only the marks made by the people during flood are remaining in many places. Also there was a suggestion that rule curves should be formed to store the flood water in the dam reservoirs.

Rule curves are formed calculating the amount of water which may flow into the dam and the quantity of water used. There should be a protocol to inform the public before opening the dams and to give them sufficient time to relocate to a safer location.

Further activities during the flood can be planned only after completing flood mapping and marking hotspots. Though a system for giving flood alert was planned near Periyar, Chalakudy, Pamba, Meenachilar, Achankovil, Manimala and Moovattupuzha river banks which were worst-hit during previous floods, it has not been finished yet.
