IMD develops technology to prevent Kerala-like deluge

New Delhi: A new technology has been designed to determine the increase in water level in rivers and reservoirs by rain and can help state governments to monitor the impact of rainfall minutely, IMD chief K J Ramesh said, in the aftermath of the deadliest deluge in Kerala.

The technology called the 'Impact Based Forecasting Approach' which shows "pre-event scenario" can help authorities in making real-time decisions, he said.

"We should be able to generate a scenario where we can take decisions to release water or not release it. It will be helpful for every state authority to take a decision. We can run this system in a pre-event scenario. We are now in a position to use to this technology into service," Ramesh said at an event organised by the Centre for Science and Environment.

The heavy downpour that ravaged Kerala for a fortnight ending August 21 caused the death of around 500 people and economic damages worth over Rs 40,000 crore.

Kerala Chief Minister Pinarayi Vijayan had said in the state assembly that there were "lapses" on the part of the IMD's rain forecast.

The IMD had forecast an estimated 98.5 mm rain in the state between 9 and 15 August, but Kerala received was 352.2 mm of rainfall, Vijayan said. The IMD director general admitted that excessive rainfall that led to floods in Kerala was a result of climate change and in terms of rainfall it was very heavy.

"The number of cyclones has increased from 10 to 18 every year as reported in Nature magazine and secondly quantum of precipitation which was 13 days has come down to 10 days," he said.

There is another technology which would help in identifying warm ocean segments that are contributing to the rapid intensification of the systems.
