Thread: Bangkok installs pumps and pipes to prepare for rain

BANGKOK(NNT) - Bangkok people often encounter flooding at various spots which affects road traffic especially on Vibhavadi Rangsit Road, which is frequently flooded after heavy rain. It is mostly caused by garbage that obstructs waterways.


Our news team recently surveyed areas along Vibhavadi-Rangsit road. It was found that the Department of Drainage and Sewerage, Bangkok Metropolitan Administration (BMA), had installed large pumps at various spots to enhance drainage. The BMA has also cooperated with military units and volunteer groups to dredge canals and collect garbage to allow water to flow unobstructed.


The Department of Highways has also implemented a project to develop drainage ditches along Vibhavadi Rangsit Road which is connected to Phahonyothin Road; the project started in the middle of last year. It is scheduled to be completed in 2022. It will make the drainage system much more efficient and help solve flooding problems in the area.


Bangkok Governor Police General Aswin Kwanmuang, convened a recent meeting of executives and heads of BMA’s departments to follow up on the progress of various operations in preparation for the rainy season. It was found that 14 flood risk areas can now drain excess water at a faster rate. The BMA has also ordered the cleaning of drainage pipes that are in total more than 6,000 kilometers long. The cleaning is currently 95 percent complete. The BMA has also undertaken the dredging of canals which cover a total distance of more than 2,000 kilometers. The dredging is now 92.6 percent complete. The meeting instructed the Department of Drainage and Sewerage, Bureau of Drainage, district offices and related agencies to accelerate operations so that they will be completed soon.

Flooding is a trivial distraction when you're sinking.

Part and parcel for expanding on surface areas that are below sea level.

Continuing to cement over most everything.
Doing away with ages old klong systems.

Done mostly by prisoners on long term sentences......

True. You can put a pig in a dress. It is still a pig.

I am sad for Bangkok, I shall miss it when it's gone.

I don't know, it will be able to reclaim its title of "Venice of the East".

That's why I purchase only above the 30th floor.

Pure luck, that the rising sealevels won't, according to thai politicians,reach the Gulf of Thailand.

Clima change ?

He lives next door

Time to relocate and build the country's new capitol metropolis.

Price of land just went up

Surin surely has room; just to piss off Newin next door

What is it with these people? Instead of dredging canals with money that could happily live in Panama, surely our glorious dictators can keep the klongs muck free by decreeing that dumping is illegal with penalties of 8-10 years and or 2-5,000 fine. That should do it, then they can invest in life jackets for all.

Nah.
Never viable.
Surin is much to Kamen for the Thai elite.

Nah, Surin sounds good to me.

The Pm could change his name to Pol Prayut

Has a ring to it

Aside, the great systems of klongs - especially within the mid-to-lower flood plain basin - have been systemically filled in for some decades, leading to the issues that we have today.
Cause and effect doesn't seem to strike as it did in the old days.

It's certainly true that many of the khlongs have been filled in and paved over to make room for roads, a massive network of waterways still exist in and around Bangkok, and many thousands of commuters still use them as part of the city transport system on a daily basis.

Many weren't filled in as I understand, but simply "bridged" over with road. On the road I lived on, the klong was only covered. It's still there.

More importantly, regarding the natural run off, is the decades long unnecessary development of the up river and basin provinces that all feed downstream - Bangkok Metro.
The annual flooding that occurs within the great basin flood plains is almost considered a contemporary issue. As it's been said, up to 100-125 years ago, these flooding "seasons" were apart of the natural flood plains that absorbed excess water and never any great concern of standing high water in Bangkok proper. Sure, once in a while - but not every year. As the water had somewhere to go and less causing water backup. The truer issues that should be addressed is the build up of up country basin provinces - the crux.

^The problem is a lack of skilled water management at the upstream dams and dams being mismanaged in the early monsoon season, better weather modelling systems need to be developed, a dry 2010 saw a desperate 'hoarding' of water early on in 2011 and then the disaster of having to shift an estimated 16 cubic kilo meters of water past (through) Bangkok and in to the gulf.

I believe the water flow managers have a system of diverting the water onto adjacent fields spaced along the rivers and presumably paying the land owners if utilised.

A plan is required to safely "shift" whatever amount is stored in the dams or elsewhere in the system. The river levels/volumes are known 24/7, similarly the dam storage volumes. Once the critical point is reached the field gates can be opened to reduce the potential volumes that can be managed from the dams, the rivers and to the open sea.

The cost of flooding Bangkok and elsewhere is able to be determined, so many ฿ 1,000,000,000 against the ฿ amount for utilising the prearranged emergency field flooding and crop destruction.

The weather forecasting alternative requires future knowledge, which will always be "expert opinion", human or AI.

The Thai government needs to deliver. They have been discussing it for years.

The problem in 2011 came about because of the previous dry year (2010), when the rains came in the early monsoon season 2011 the authorities at Buhmibol dam held on to more water than they should have, they expected a short monsoon like the previous year, that didn't happen, and they found themselves at over capacity and the rains still coning, and coming, and coming. They then estimated they needed to loose the equivalent of 16 Cubic KM of water to down stream, they tried to send it through the Chao Praya river and the Nakhon Nayok river and in to the gulf, but the rivers couldn't cope, and circa 20 million cubic meters of water overflowed from the river and in to the city every day of the last week of November.

Their solution in 2011 failed due to an inadequate solution. The "problem" appears not to be fixed yet.

My link illustrates lots of finger pointing.

Yes. There really are two problems. Rainwater flowing down seems to be the target here. The seawater coming up might take a little longer to arrive and no number of canals is going to fix things when the floodwater coming down meets the sea coming up.

Certainly, if the rivers are tidal up to the cities.

However it's just another computation to add to the, "Do we open the field flooding gates NOW" solution.

If in fact there is the "field flooding" option. Which may or may not be the most beneficial. Does cleaning the cities cause a positive or negative outcome? Who are the most affected city citizens? Upright, voting, taxpaying citizens or "others"?

Some might suggest that the modern damming systems and related cementing over are part and parcel to the greater problems of annual and zealous flooding.

Deeper research will lead one to discover that these events didn't really occur, in an overbearing form, generations ago.
