The government is confident there will not be a repetition of the 2011 massive flooding because the water management system has been fully prepared, government spokesman Lt Gen Sansern Kaewkamnerd said on Friday (Oct 13).
The spokesman said Prime Minister Prayut Chan-o-cha has been reported on the current situation and assured by concerned agencies that there will not be massive flooding this year because many factors, particularly the volumes of water, in 2011 and 2017 are much different.
Moreover, the water management by concerned agencies haห been integrated. The past problems have been taken as a lesson to make corrections, Lt Gen Sansern said.
As of Oct 11 this year, the total volume of water in all dams in the North was 18.3 billion cubic metres, compared to 24.1 billion cu/m on Oct 11, 2011. In the Central Region, the total volume of water in all dams on Oct 11 this year was 1.2 billion cu/m, compared to 1.3 billion cu/m in 2011.
The water levels measured in Muang district of Nakhon Sawan, Chao Phraya Dam in Chai Nat, and Ayutthaya’s Bang Sai district were also lower than in 2011.
As for the northern run-off due to heavy rain in the North, government agencies have controlled the level of water above the Chao Phraya River, diverted water to the irrigated zones on both sides of the river, and used low-lying areas to retain the floodwater. These measures have reduced the volume of water flowing downstream, Lt Gen Sansern said.
The Disaster Prevention and Mitigation Department, with support from provincial authorities, military units and local administrations, have provided assistance to people affected by floods. People have been warned to closely followed the government’s weather forecasts.
In Bangkok, the ten districts risky of being flooded are Bang Sue, Dusit, Phra Nakhon, Yannawa, Khlong Toei, Samphanthawong, Bang Kho Laem, Bangkok Noi, Khlong San and Rat Burana. The Bangkok Metropolitan Administration has built a 77-kilometre flood prevention embankment, of which height ranges from 2.80 to 3.50 metres.
The sluice gate at Bang Sai in Ayutthaya, the last watergate before Bangkok, is discharging water at the rate of 2,200 cubic metres per second, compared to 4,000 cu/m in 2011.
