BANGKOK
Capital to get a new storm tunnel

BANGKOK: -- A new tunnel in Bangkok to drain floodwater from five inner districts northwards to a Chao Phraya outlet in Nonthaburi will be ready for use by September 2016, after a contract was signed yesterday between the Bangkok Metropolitan Administration and the contractors.

The 6.4km tunnel is the second in the capital and will channel waters in Huay Khwang, Din Daeng, Chatuchak, Phya Thai and Dusit areas, including six major roads prone to flooding after heavy rain, Bangkok Governor Sukhumbhand Paribatra said.

Half of the Bt2.44-billion budget to build the tunnel is subsidised by the government, he said, adding that the BMA was planning to build another two such tunnels.

I have to ask - where is the first one?

And how does a tunnel work in such conditions?

I thought Bangkok was as low as you can go . . . . . excuse the pun.

That ditch is Boss Kean's ditch. And I told him that dirt in it's your dirt. What's your dirt doin' in his ditch?

Luke: I don't know, Boss.

Boss Paul: You better get in there and get it out, boy.

The BMA could take some advice from the Malaysians, they seem to be on top of their flood problems in KL,but of course that wont happen.

Maybe can do a deal and use all this Rubber ?

as the sea is rising how will a tunnel help flood water ? go where ?

I believe that's a reference to the Rama 9-Ramkhamhaeng tunnel which opened back in 2011.

Areas near the mouth of the river are not usually rock formations, but silt that has come down the river to create delta like land. These areas were originally settled then became larger cities over time. This type of formation naturally sink (pumping water out of the ground only makes it sink faster - but it will continue anyways) over time. By building on that land, it blocks the new silt from flowing down onto the land to replenish the land - this leads to a number of cities around the world in areas like this to sink (New Orleans being one is actually below sea level in many areas). Building dikes and channels which are pumped out of the city (onto the other side of the dikes) can keep an area viable for centuries until the inevitable happens. So yes, this type of thing is typically part of the solution. You will also have to have new construction build up the land beneath it (similar to the way Singapore is expanding it's territory).

That's all Nonthaburi needs, more flood water. I hope they are suitably grateful.

I'm not a hydrologist or a expert in floods and/or drainage matter BUT when the sh** hit the fan with the floods of 2011, Nonthaburi flooded before Bangkok. Even if it were only to drain 'certain' parts of Bangkok, you are putting the water in the Chaophaya north of Bangkok and it will flow back to Bangkok. AND what if the water level in the Chaophaya is too high for the water to be pumped out of the tunnel? Another pocket-lining project for sure.

They will use the tunnels to fill up the dams up north

[nong38]

Surely they mean floodwater hub?

[MESmith]

They can make a very long hose pipe to siphon off the flood water

[Cuban]

Wasn't there a "No Bangkok flooding" edict from the government a year or so ago - didn't the water get the memo ?

Or an <deleted> big shanghai!

Why are the pumping water out up the river? And doesn't Nonthaburi flood pretty badly already? This sounds like an enhancement on the last Bangkok flood plan, all of which amounted to "save our butt by flooding all our neighbors around us."

[MaiChai]

Surely water will be forced to run up hill to go back on itself? I live in Huay Kwang and it would make more sense to divert it eastwards to meet another water course heading southwards?

[lee b]

very good idea.

No Thailand is the HUB of pushing water, not pumping water, that is why all this pumping in 2011 we had the floods..

Bangkok to get a new floodwater tunnel

Theres a shining light at the end of that tunnel - looks like a few 3-pointed stars.

The truth is nothing can be done! Just like a cancer, take chemo to preserve the life a little bit more.. ocean is rising, BKK is only one meter or less above the water.. huh? What else need to be said? Is just a matter of time!

In few years the one thing to do is... pack and move!

Shall we make a bet that it will take more then ten years ... so unless you think 10 is a few

We flooded in nothaburi.. but this tunnel if it ever gets there will go into the river.. and that is not a problem

It is stupid however as it will make the river higher and the water will enter BKK a second time.. I fail to see the logic there.

This topic is 'boring".

That boat thing was remarkable. How utterly stupid to think that boat propellers could speed up the flow of a giant river and prevent flooding. This is the sort of thing that only a child could believe....or a Thai

[JoeThePoster]

So much easier to blow away rain clouds using 1000 jet engines.

[MaiChai]

Land is worth alot of money in Bangkok. Be time the government started spending money on protecting it rather than wasting money on the rice scheme and high speed trains. If it can be done in the Netherlands then it can be done in Thailand, so there are no excuses for not doing it.

Ironic that they only talk about this when flooding is imminent. Would i be the first to say Thais are not good at planning?
