Bangkok strengthens flood defences as water discharged upstream

Bangkok’s flood defences are being strengthened to deal with water released from the northern part of the country, the city’s governor Aswin Kwanmuang said on Thursday.

 

On Tuesday, the Royal Irrigation Department warned 11 provinces – Bangkok, Samut Prakan, Pathum Thani, Nonthaburi, Chainat, Singburi, Angthong, Suphanburi, Phra Nakhon Si Ayutthaya, Lopburi and Uthai Thani – to be ready for more water released from the Chao Phraya Dam in Chai Nut province.

 

Aswin explained that Bangkok’s flood barriers along the Chao Phraya River can resist water levels of 2,500 to 3,000 cubic metres per second. City officials have been ordered to check and repair barriers along the city’s main river and canals.

 

Officials have also placed sandbags in flood-prone communities to protect residents. The governor said that city workers were on standby to build temporary bridges in case flooding overwhelmed some areas.

not exactly confidence educing, temporary fix to a predictable reoccurring problem. the issue of bangkok, and other areas of thailand, flooding needs addressing, the uk acknowledged the issue of london flooding in the 1970s and opened the thames flood barrier in the 1980s. similar proactive action and capital investment needs to be made in thailand.

The only way Bangkok can protect itself from annual deluges is to widen or dredge much deeper, the Chao Phraya substantially as it flows through the city. The river is only 36ft deep I believe.

It seems someone went all out to devise a flood prevention

Every year there are floods and the only defence is sand bags, that no doubt get dumped into the river afterwards as no one wants to remove them

Sand-bags, Thai lands defense against the rising tides.

Useless. as I found out in 2011.

How about clearing out the millions of tonnes of water hyacinth clogging up the river and klongs ???

As usual, waiting for the floods before building temporary bridges (REACTIVE)- be PRO-ACTIVE and build the bridges now!!

A different problem and more difficult to solve. A seaward barrier only helps at high spring (sea) tides but (fresh) water releases from the Chao Phraya River basin near year may be needed every day if the dams upstream are full. Bangkok needs much better drainage and less overburden - it is still sinking, which is partly due to continued construction and 'development'.

Can't edit - read near year end.
