'Rai' adds more water to dams despite havoc in vast areas it wreaks

 

 

BANGKOK: -- Rai tropical depression is now sweeping across Thailand from the northeast through the east, central and northern regions,  dumping heavy to heaviest rains, and leaving behind trails of destruction from flashfloods, floodings, landslides, and fallen trees on vehicles, houses and temples.

 

Although the depression will wreak havoc on many areas along its path, it also added more water to several dams that still are in dire need of water for supply to farmers so that they can farm throughout the dry season next year.

 

Ubonrat dam in Ubon Ratchathani is now reported to have 37% of its storage capacity, and is taking in 17 million cubics of water a day.

 

With water still flowing in the reservoir, it is expected that water shortage for farming along its irrigation area could be eased next year.

Meanwhile the Royal Irrigation Department deputy director-general Mr Thongplaew Kongchan said four major irrigation dams in the country still need more water.

 

Now the water stored in these dams are still at 48% of total storage capacity which are still worrying  level, he said.

 

He voiced optimism that Rai depression would add more water to these major dams in the Northeast region.

Amazing that Esaan still needs water, build a pipeline from here ( Phang Nga ) to there and solve the problem I would say...  way more than enough rain and floods here

PM don't use section 44 to deny entrance into kingdom ?

 

lol

Is that even technically possible and if so is it economically feasible given the rice price and the price of building and operating such a pipeline ?.

 

Must be a huge pipeline.. and huge consumption of power to transport the water.. I doubt its economical.

Have you any idea of the distance involved? Perhaps nearly 1,000 end to end. But that is only a single pipeline from south to north. You will also need distribution pipelines from east to west.

 

Then of course you need to work out the diameter of that pipe. For example the volume of a 5 metre diameter pipe 1 metre in length is

19.63 cubic metres and the weight of the water in that 1 metre length is 19.63 tonnes. Multiply that by 1,000 to give you a pipeline only 1 km long and the weight of water comes to about 19,635 tonnes. Multiply THAT by 1,000 to give you a pipeline 1,000 km long and the weight of water becomes over 19 million tonnes.

 

You will need some very big pumps to shift that lot so you will need to put in pumping stations every 10 km or so. Then of course you will need electricity to power them, so you will need extra power stations as well.

 

If you want to bury the pipelines the will need to dig a trench  perhaps 8 metres wide and 8 metres deep ll the way from end to end through or around villages and towns, roads and railway lines, perhaps national parks as well. You may need compulsory purchase orders, relocation packages and probably Section 44 as well.

 

I suspect that the cost may be 3 or 4 trillion baht, or even more but it will supply jobs for thousands of people for decades. Trucking companies, heavy road working equipment companies will do very well from this and it will be spread across some of the country, Issan particularly, but not all of the country or all of the people.

A pipeline from Phang Nga to central Isan?

More than 1000 km, pumping upward about 250 m height difference?

Just a dream.

 

Much closer: draining water from the Mekong during high water periods (if only the Chinese would always tell when they open the dams).

 

Dams. dams, dams.

The only solution.

 

In the end (depending on climate development): abandon, migrate (which already takes place in a certain way in the form of work migration).
