Rule curve of hydel dams in Kerala amended to avoid flooding: Water Commission

36

Thiruvananthapuram: The Central Water Commission (CWC) has amended rule curve of hydel dams in Kerala foreseeing the possibility of repetition of 2018 flooding scenario.

A rule curve is a pre-defined level of water to be maintained on a specified date in the reservoir to fill it in stages during the monsoon season.

The power consumption in the state has reduced substantially during the lockdown period which has resulted in less water being drawn by hydroelectric dams in Kerala.

As a result, the storage capacity of the reservoirs is higher than it was the previous year. This could potentially cause another flood in the state if the water is not released from the reservoirs before the monsoon, experts said.

The weatherman has predicted above normal rainfall for this year in the country.
