BANGKOK (NNT) - The Council of Engineers of Thailand (COET) is proposing that relevant bodies quickly make improvements to the flood prevention infrastructure along the Chao Phraya River, and warned that there is a probability of Bangkok becoming submerged in 10 years if the water issue is not properly addressed.

 

COET President Suchatvee Suwansawat and volunteer engineers from the COET visited the area underneath Krung Thon Bridge in Bang Phlat district of Bangkok, where water had gushed in from the Chao Phraya River and flooded nearby roads and communities. The team inspected the 2.5-meter floodwall and flood prevention infrastructure in the area, saying afterward that they found many spots needing improvement. The engineers said the floodwall constructed 10 years ago was damaged, with gaps and holes present. Water had gushed in from these openings below the top of the floodwall and resulted in the recent flooding in the area.

 

The COET team proposed 4 methods of addressing the flood issue, the first of which is to use technology to predict, forecast and analyze flood risks – noting that storm surges can be recognized before they bring impact. The second method is the completion of the levees along the Chao Phraya River, which will be supported by computer-controlled water gates that can operate automatically. The third proposed method is the use of 2-layered floodwalls for increased flood protection reliability, and the fourth method involves the construction of a water gates-equipped dam at the mouth of the Chao Phraya River.

 

Prof. Suchatvee, who is also the rector of King Mongkut’s Institute of Technology Ladkrabang, said there was a high probability of Bangkok becoming submerged 10 years from now if the correct remedies to the problem are not applied.

5. Giant wall of sponges, that can be wrung out during drought

So that would be a hard no to moving to Bangkok ????

Relocate the capital city to somewhere more manageable and do away with this annual event. ..................

His first marvellous technological proposal was to know when it was likely to flood ! Duh !  Isn't that called a weather forecast ? Already got that. Doesn't hold much hope for any more of his ideas.

Clean the garbage out of the drains and klongs would be a good place to start, but there’s a short supply of slaves in the country right now to do the dirty work.

Little room for income generation for maintenance services, too easy to check prices. Better to wait until the defences fail and have to be rebuilt, much more room for inflation. Seems to be the practice for roads as well.

To the Thai Council of Engineers of Thailand (COET), great ideas gentlemen (I am guessing that most of you are males). but you really need to consult the topographical and geological maps of the Choa Praya Basin, and examine them carefully.  As a former student of Applied Mathematics, with a major in fluid dynamics, it seems to me that your proposals will fail.  The famous Zuider Zee Project in the Netherlands worked because the topography and geology were "right" (but even this project will fail if the polar ice caps melt).   A better sugestion is to follow the Indonesian example, and start looking for a location for a new capital city now.

As Myanmar has done, with Gvt buildings anyway. But Bangkok would remain the most major city for a long time after.

More pumps and sandbags? ????

Time to call in the Dutch?!

It's been flooding there for a long time.  I see old photos of Bangkok back in the 20's and 30's that show flooding then.

May I recommend a reliable foreign professional to sole flooding problems.

Message to the Engineering Council :-

"Water flows downhill"

Funny enough Prime Minister Phibun wanted to move the capital to Phechabun back in 1944. It was rejected by small minded politicians. They don't Change! I was probably an idea ahead of its time. But as soon as the major roads were built it should have been revisted.

"The engineers said the floodwall constructed 10 years ago was damaged, with gaps and holes present. Water had gushed in from these openings below the top of the floodwall and resulted in the recent flooding in the area."

 

So this means that these guys with all these ideas never thought to do a yearly inspection during the nonflooding period to see if there were any breaches in the wall and fix them before the next rainy season?

I would guess that's very difficult to see where there are weaknesses in a floodwall when there is no water to give inspectors a clue. The tiniest fissure can quickly erode into a major breach once water begins to flow through it.

 

That's a lesson learned, of course from the little Dutch boy who stuck his finger in the hole in the dam.

there is only one way to do this, increase the flow of water in the river as it passes through BKK and into the open sea.

This is a major engineering task featuring digging out the bottom on a decent scale.

and repeat every year.

Sand bags?????????

 

If I remember, this "council" planned flood work some 15-20 years ago...they actually designed the water to flow uphill.....very clever stuff..huge tunnels...massive gates and pumps...it didn't work!...It still doesn't work and BKK still floods!

those sound pretty visible to me

Cant even build roads  properly or  repair them, take  your  life in your  hamds round  by me,new roads  crumble after 6  months, theyll be needing the cave rescue team soon to get folk  out.

Like I said, it only needs a tiny fissure for the water to start flowing. Once flowing, water is very erosive and will turn that small opening into a gaping hole that can be seen.

 

Seeing gaps and holes after a breach is no evidence that they were visible before.

helps if they dont use concrete with so  much water in its  got  no strength

Im not an engineer, but the land which has highway 347, dig it out and use it as a flood land.
