Thread: Bangkok prepares for floods as more rain is likely

BANGKOK (NNT) - Police General Atsawin Kwanmuang, Governor of Bangkok said today that a plan and preparations for flooding in Bangkok have now been finished. Waterways, reservoirs, and water level monitoring systems are ready to prevent an inundation.


By using weather forecast reports from the Meteorological Department’s 24-hour radar monitoring system, along with water pumps installed in areas at risk of flooding, as well as officers at water gates ready to control the flow rate, Bangkok is now prepared if rains are heavier than usual. Aside from the prevention efforts, the governor also revealed that officers are ready to help evacuate residents to safe places.


In addition, Bangkok Metropolitan Administration(BMA) has also been cooperating with provinces such as Nonthaburi, Pathum Thani, Samut Prakan, Samut Sakorn, and Nakhon Pathom as well as the Department of Disaster Prevention and Mitigation, the Department of Royal Irrigation, and the 1st Army Area that often conducts safety drills with the BMA.


Large-scale construction projects such as the Skytrain and subways were also informed by BMA to clear objects that may block drainage systems and waterways.

Flooding in 30 provinces, 6 dead

The Royal Irrigation Department (RID) will increase the discharge rate from the Chao Phraya Dam to make room for the increasing volume of runoff from the North.
A warning of possible flooding is issued for communities downstream.
The department on Tuesday said heavy rain in the upper part of the country caused a huge volume of water to flow into the Chao Phraya River in Nakhon Sawan. The water level in the river rapidly rose.
The department will increase the water discharge rate at the Chao Phaya Dam to accommodate this runoff in the reservoir.
People living downstream should keep a close watch on river levels and news reports, the RID News announcement said.
RID director-general Praphit Chanma said the water station in Nakhon Sawan on Tuesday measured the flow in the Chao Phraya River at 2,521 cubic metres of water per second. It was 1.88 metres below the high mark and rising.
It would be joined by runoff from the Sakae Krang River before flowing into the Chao Phraya Dam reservoir.
The department will take 306 cubic metres of water per second into its irrigation system and it will adjust the discharge rate at the dam to 2,631 cubic metres of water per second.
This will affect riverside communities and water levels in areas outside flood embankments will increase.
Areas likely to be affected are: Ban Tha Sai village and tambon Pho Nang Dam in Sappaya district of Chai Nat province; Wat Sue Kham and Wat Sing In Buri district, Phrom Buri and Muang districts of Sing Buri province; Khlong Phong Pheng canal and Wat Chai Yo in tambon Thewarat of Chai Yo district, and Pa Mok district of Ang Thong province; and Khlong Bang Ban in tambon Hua Wiang of Sena district, tambon Lat Chid and tambon Tha Din Daeng of Phak Hai district in Ayutthaya.
If the water level in upstream areas continues to increase, it will result in a huge volume of water flowing into the Chao Phraya River, the department said.
The department has adjusted its water management plan by releasing water and turning low-lying areas into water retention areas. Water discharge from the Chao Phraya Dam will be increased to accomodate the approaching surge from the North, the department said.
It said updates will be issued.

Chao Phraya Dam to discharge more water

Thai Authorities Warn of Possible Flooding in Bangkok and Adjacent Provinces

BANGKOK (NNT) - Thailand’s Royal Irrigation Department has warned authorities in Bangkok, Nonthaburi and Pathum Thani provinces to brace for possible flooding, after the department decided to increase the discharge rate of the Chao Phraya Dam in Chai Nat, in anticipation of more heavy rainfall.


Ayutthaya irrigation project director Thanakorn Tantikul said the decision was taken to prevent floods in the northern part of the country, as a monsoon trough makes its way down the length of the country towards the Central Plains and upper South. Provinces downstream of Chai Nat have been advised to prepare for a possible surge of water from the dam, which may cause floods in low-lying areas.


Meanwhile, Prime Minister Prayut Chan-o-cha said the government is preparing plans to prevent floods in the more central and southern parts of the country, including Bangkok and its adjacent provinces, as heavy rain was still reported in isolated pockets, meaning the risk of flash floods and landslides remains high.


He said the Department of Disaster Prevention and Mitigation has been instructed to come up with a plan to deal with the nation’s flood problem. The department will also dispatch officials and equipment, such as water pumps and rescue boats, to help those affected.

Officials race to divert water into the Gulf to prevent Chao Phraya overflowing

Thailand’s National Water Resources Office and the Royal Irrigation Department have been racing against time to divert massive amounts of water from flowing into the Chao Phraya River, by discharging it directly into the Gulf of Thailand, ahead of the peak water inflow at the confluence of the Ping, Wang, Yom and Nan rivers in Nakhon Sawan province.


Mr. Somkiat Prajamwong, secretary-general of the National Water Resources Office, said today (Wednesday) that the flow of water at the C2 station, in Muang district of Nakhon Sawan, where the four rivers meet to form the Chao Phraya River, will reach a peak flow of 2,683 cubic metre/second in the next 1 or 2 days, but will not exceed 2,820 cubic/second.


He assured that water will not overflow the river’s banks, but low-lying areas may be flooded because the peak could reach 3,500 cubic metres/second.


He noted that the management of water from the Pasak Jolasid Dam is crucial in protecting Ayutthaya and Bangkok from flooding, besides the need to control the water level in the Chao Phraya River itself, to prevent it from overflowing. Irrigation officials have, therefore, reduced the volume of water to be discharged through the Pasak Jolasid Dam.

He also said that excess water must be prevented from flowing into Lop Buri province, by diverting it into Khlong Rapeepat.


To allay the concerns of residents in Bangkok, Pathum Thani and Nonthaburi about possible flooding, Mr. Somkiat said both his office and the Royal Irrigation Department are working together to limit the volume of water released from the Chao Phraya Dam to under 2,800 cubic metres/second and to divert water into the Gulf, via the western and eastern flanks of the Chao Phraya, to ease pressure on the river.


“This is possible because the tide in the Gulf is not high yet,” he said, adding that he has to monitor the situation on an hourly basis, to make sure that the Chao Phraya River is not swollen and not too much water is released downstream from the Chao Phraya Dam in Chainat province.

I've been working daily for the last month raising walls in preparation for flooding.

I wish everyone in Bangkok and surrounding areas to stay safe and dry.
