Kerala: Dams Floods 2018: Follow Rule Curves to Avoid Flood Disasters

Unprecedented Kerala deluge[1] that swept through the coastal state on the day of Independence day 2018 was most disastrous flood incident in the year. It has also been termed as one the worst flood in the state and reminded the people of July 1924 and July 1962 flood calamities. Many experts, several reports and studies have established the role of dams in worsening the deluge. According to reports, 35 out of the 46 dams within the state were opened for the first time in history[2].

In this flood crisis, Idukki & Idamalayar two of the Kerala’s biggest dams along with about two dozen others, are releasing water, adding to the floods and the disaster. Why are Idukki and Idamalayar, both having live storage capacity above a Billion Cubic Meters, releasing water NOW, when whole of Kerala is facing floods due to recent excessive rains? Standard excuse: The dams are full and they have no option but to release the water, they cannot store more. But why did they wait to start releasing water till the dams are full and they are faced with TINA: There is No Alternative. This love to be in TINA situation seems like a disease affecting all dam operators.
