explains a sharp drop in rainfall since 2011
Since the current volume of rainwater is lower than it was in 2011, when a significant flood occurred, Prime Minister Paetongtarn Shinawatra has assured the public that Bangkok wo n’t be inundated by floods.
Ms. Paetongtarn conducted an inspection of the water supply on Wednesday at the Royal Irrigation Department in Nonthaburi’s Pak Kret city. She said that in 2011, the state was hit by five winds, compared to this year, when only one surprise has affected the land.
Also, rainfall in 2011 was over 25 % higher than usual, while this year has seen simply 2 % more rainfall than normal. Compared to 2011, when they were now at capacity and required to release excess water, big dams can also keep more water this year.
There is no need to worry about possible flooding in Bangkok, according to the statement. Bangkok will not be flooded”, Ms Paetongtarn stated.
On Wednesday, precipitation in some northern areas caused water to flow from the Ping, Wang, Yom, and Nan river into the Chao Phraya River in Nakhon Sawan. The Chao Phraya Dam in Chai Nat releases water at a rate of 1, 899 cubic meters per second ( m3/s ). This is at a rate of 1, 899 cubic meters per second ( m3/s ).
The lower Chao Phraya River basin’s Department of Water Resources is keeping an eye on the assessment station’s water stream to prevent it exceeding 3, 000 m3/s.
Local officials in the lower Chao Phraya River valley, including Bangkok and the adjacent regions, are preparing to handle the approaching liquid from the North, according to a cause. With a combined power of around 164 million m3 per day, this process involves draining water through numerous rivers and accelerating pumping activities to the Gulf of Thailand.
The Meteorological Department has forecast that from Monday until Thursday, a modest warm air mass from China may stretched over the North, Northeast, and South China Sea, combined with a rain bowl across the lower North, lower Northeast, Central, and Eastern areas. This will result in unpredictable wind in upper Thailand, with storms, strong winds, and heavy rainfall in some places, particularly in the North, Northeast, Central, Bangkok and its proximity, and the Eastern area.
Moreover, great sea conditions may affect areas along the throats of the Chao Phraya, Mae Klong, and Tha Chin river in Samut Songkhram, Samut Sakhon, Nakhon Pathom, Nonthaburi, Bangkok, and Samut Prakan regions.
Meanwhile, Jirayu Houngsub, an adviser to the prime minister and spokesman for the disaster relief operations centre, said the National Water Resources Office ( ONWR ) expects torrential rains until Oct 9 to cause water levels in the Kok River, in the northern province of Chiang Rai, to overflow. This may influence 147 km² across six regions: Muang, Wiang Chai, Wiang Chiang Rung, Mae Chan, Doi Luang, and Chiang Saen.
