Officials race to divert water into the Gulf to prevent Chao Phraya overflowing

Thailand’s National Water Resources Office and the Royal Irrigation Department have been racing against time to divert massive amounts of water from flowing into the Chao Phraya River, by discharging it directly into the Gulf of Thailand, ahead of the peak water inflow at the confluence of the Ping, Wang, Yom and Nan rivers in Nakhon Sawan province.

 

Mr. Somkiat Prajamwong, secretary-general of the National Water Resources Office, said today (Wednesday) that the flow of water at the C2 station, in Muang district of Nakhon Sawan, where the four rivers meet to form the Chao Phraya River, will reach a peak flow of 2,683 cubic metre/second in the next 1 or 2 days, but will not exceed 2,820 cubic/second.

 

He assured that water will not overflow the river’s banks, but low-lying areas may be flooded because the peak could reach 3,500 cubic metres/second.

So!

 

How is this water going to reach the gulf if not via the Chao Phraya River?

 

And if it is possible to divert the water directly into the Gulf, why don't they just do this every time to avoid flooding?

You are just being difficult now????

It will not exceed 2,820, but it could reach 3,500. Very reassuring...

This one statement sums up Thailand so succinctly .

So which one is it?

Thailand's Great Basin.

A very broad and natural occurring flood basin. 

Every year.

Like clockwork. 

 

In the old days, sure there was high water, but nothing like the annual flooding that we've witnessed of the last couple of generations. And only a few can figure it out as to why. ????????

 

Oh...btw, the river confluence at Nakon Sawan is made up of five major rivers - not four.

Unfortunately not available until next year.

 

Giant Bangkok drainage tunnel almost 90% complete

They also use the existing complex of canals to push water to the west and east.

 

And they flood land north of Bangkok as storage and let that drain off.

Actually there are other rivers leading to the sea but in 2011 some were blocked by local governments (plus it being about 90% more water at the time).

One solution to rivers overflowing adopted by South Korea was the "River Basin" plan. In Seoul, The Han River has almost 90 sq. kilometer of basin which absorbed large volume of river water during raining season and recreation spaces during dry season. I think Thalland does have some small scale planning for basins but clearly insufficient.

I have this recurring mental picture of a frantic bucket chain of khaki clad government officials stretching from the river bank just north of Bangkok to the beach at the head of the Gulf of Thailand...

I would look at the possibility of digging a very major channel (like a fairly large river, not a normal drainage channel)  from the Chao Phraya River at a point a little lower than Ayuttaya, westwards to the Tha Chin River which thence flows to debouch into the Gulf at Samut Sakhon. Job done !

Simple souls such as I would question how water from the confluence of several rivers, at a volume likely to exceed 3000 cubic metres a second, can be diverted directly to the Gulf of Thailand some 240km to the south without using the natural course of the Chao Phaya River.

 

Please rush me the answer. I enclose ThB 20 for postage......

 

Amazing Thailand......????
