FLOODS 2018 -A TIME LINE

Beginning in July 2018, severe floods affected the south Indian state of Kerala, dworst flooding in Kerala in nearly a century. Over 483 people died, 14 are missing. At least a million people were evacuated, mainly from , , Edanad, Aranmula, Kozhencherry, Ayiroor, Ranni, Pandalam, Kuttanad, Aluva, and Chalakudy. All 14 districts of the state were placed on red alert. According to the Kerala government, one-sixth of the total population of Kerala had been directly affected by the floods and related incidents. The Indian government had declared it a Level 3 Calamity or “calamity of a severe nature” .It is the worst flood in Kerala after the great ue to unusually high rainfall during the monsoon season. It was the flood of 99 that happened in 1924.

Thirty-five out of the fifty-four within the state were opened for the first time in history. All five overflow gates of the Idukki were opened at the same time, for the first time in 26 years. Heavy rains in Wayanad and Idukki have caused severe landslides and have left the hilly districts isolated.

Causes

.Rainfall of high intensity with long duration this season and its frequency caused flooding . .Unregulated construction & management of Dams are one of the causes that lead to floods in Kerala . .Deforestation of hill areas causes sudden rising of water as cutting of trees reduces the water carrying/storing capacity of the ground. .Haphazard construction on hills, failure of embankments to check water flow when heavy rainfall occurs, aggravates the flood problem. . Loosening of soils due to mining, quarrying .

Being instructed by the Cabinet Secretary, senior officers of Defense Services, NDRF, NDMA and secretaries of Civilian Ministries conducted meetings with Kerala Chief Secretary . Following the decisions taken during these meetings, the Centre launched massive rescue and relief operations . In one of the largest rescue operations, 40 helicopters, 31 aircraft, 182 teams for rescue, 18 medical teams of defense forces, 58 teams of NDRF and 7 companies of Central Armed Police Forces were pressed into service along with over 500 boats and necessary rescue equipments. Dozens of helicopters dropped tonnes of food, medicine and water over areas cut off by damaged roads and bridges. Helicopters were also involved in airlifting people marooned by the flooding to safety.

Impact

The state government has estimated a loss of Rs 20,000 crore, with Idukki, Malappuram, Kottayam and Ernakulam districts being the worst affected in the Kerala floods. Floods in the southern Indian state of Kerala killed more than 410 people. The government estimates about one lakh buildings, which includes people’s houses, have been damaged, over 10,000km of highways and roads and hundreds of bridges have been washed away, and crops in millionsof hectares of land have been lost in the Kerala floods .

Schools in all 14 districts of Kerala were closed and some districts have banned tourists because of safety concerns. Maintaining sanitation and preventing disease in relief camps housing more than 800,000 people was a significant challenge. Authorities also had to restore regular supplies of clean drinking water and electricity to the state’s 33 million residents.
