Flash floods, heavy rainfall due to global warming, says Earth Sciences Secretary

Madhavan Rajeevan, Secretary, Ministry of Earth Sciences, on Tuesday said the northeast monsoon was likely to be favourable and that heavy rainfall could be expected during the period.

Addressing a press meet here at the National Institute of Ocean Technology, he said the official forecast for the monsoon would be released shortly. “Although the seasonal rainfall is down by 8% this year, we had plenty of heavy rainfall incidents during the southwest monsoon,” he said.

Mr. Rajeevan said that due to global warming, incidents of heavy rainfall and resultant flash floods were likely to increase every year.

Asked about the recent unprecedented heavy rain and floods in Kerala, he said that there was widespread heavy rainfall and the State received enough warning. “From Kerala, we have learnt a lot of new things. We need a good water management system, especially a flood warning system; it is not rocket technology. We should know how much water is going into the dam and need to plan to release accordingly and not rely on old thumb rules,” he said.

Flood warning system

Mr. Rajeevan also said that an early flood warning system for Chennai would be tested soon. It has been developed jointly by the National Centre for Coastal Research, IIT Mumbai and IIT Madras, and Institute of Remote Sensing-Anna University.

He was in the city to announce the 4th International Science Festival (IISF - 2018), to be held in Lucknow from October 5 to 8.
