Governor blames topography for severe flooding in Bangkok

A basin-like formation at Mcot Junction, which makes it difficult to drain water out, was the cause of severe flooding in the area after heavy rains on Wednesday (September 23), Bangkok Governor Aswin Kwanmuang explained.

 

Aswin said that several districts in Bangkok faced the same issue, especially Wang Thonglang and Din Daeng districts that saw 124 millimetres and 120mm of rain per hour respectively.

 

The strong winds also brought down many trees on the streets in Din Daeng. He said officials in the area were told to cut the trees so that traffic could move again.

 

In Huai Khwang district, officials had to drain the floodwater with two pumps, while taking out a big amount of trash which was blocking the water flow.

 

Mcot Junction, located in Huai Khwang district, was a hot topic of discussion on the Internet after a video showing vehicles being swept into the flood by the wave went viral.

 

The governor said the junction had a unique topography like a basin, leading to water logging during rains and causing major flooding.

Yup. No one has ever managed to figure out how to deal with difficult topographies.

Well yes, water tends not to drain naturally out of a basin....

 

Perhaps the ‘topography’ should have been considered when building up the area. Too late now of course, clean drains and effective pumping stations would help, but ultimately that was a lot of rain coming down over 24 hrs - many / most cities would likely have areas subject to flooding.

Maybe it's time to call the Dutch engineers to manage the water, just like in 2011.....

In 1979 I arrived in Bangkok. A week later I had to wade in water just below my knee to my apartment in soi 22 Sukhumvit. Only way to get there as there were no talks or tuk tuks.

 

Not much progress in 40 years.

Yeah.  Bring in the Dutch.  They started building their water management systems over 1000 years ago.  But I'm afraid BKK doesn't have that long...  And Thailand doesn't have that much money.

 

Anyone thinking this is a Thai specific problem, do a Goggle search for Beta and Houston.

Thailand has loads of money, that is why the THB is so high.

They're too busy managing their amnesty extensions to worry about that now

i for one am starting to really truly appreciate the greatness in many of these daily articles. where else on earth can you sit back and have 3 ring circus entertainment....every single day. 

Bangkok is close to the ocean and is mostly pancake flat, so floods

happen. Especially with so many khlongs covered over and filled in, great

modern city planning. Good Luck Bangkok, the future is not

going to be any better

Geezer

...and the Thais are seriously considering building a nuclear power station.......God forbid.

Well yes...finally they figured out why after 40 years. ????

 

I thought I read on the news that they well prepared for the storm in advance...????

How many decades has this been happening, and every year it floods it's as though the government is seeing it for the first time.

Yup, water runs downhill, always has and always will, keep building more condos and shopping malls, concrete everything, but never increase infrastructure such as drainage.

And it has quite a few Dykes available.

Tons of progress, don't be ridiculous.

Throw down the volume of rain that fell that night anywhere and see how it copes.  Generally the floods drain away pretty quickly these days, often within an hour or so of the rain stopping.

As Bangkok is basically built on a river delta i would think 1000's of years and any suggestion it can be managed other than mitigated shows just how little understanding the authorities have.

Bangkok is one metre above sea level. If one thinks of Thailand as a bath tub, Krung Thep is the drain hole. What else do they expect?

King Rama 9 said "Bangkok is like a toilet without a flush".   Another time, he was talking to government officials about never building in the areas north of Bangkok, as every so often, it fills up and drains slowly.  The video of him speaking about this was aired several years ago during the big floods there.  Bangkok is about 4 meters above sea level, 25 km away.  Ayutthaya is 7 meters above sea level 90  km away .  Singburi is 17 meters above sea level, 150 km away.    Water simply does not drain.

Geezer

You have to remember Thailand is flat, the grade down from Chiang Mai to bangkok is what about 200 to 300 feet over a 400 mile distance. Not draing very fast

thats why theres a sinking fund on condos? the mud under is  not good for foundations

If the all the denim sellers moved there it could become their jean pool .. just let that sink in a moment .. 

I wonder if they will soon be blaming the political situation on geography?
