record

Continuous heavy rains cause more rainfall than every year.

Northern and Northeast Areas

Many reservoirs are so full that they need to be drained.

especially the Sirindhorn Dam

Ubon Ratchathani Province

More than 70 percent of the dam's water is now raising concerns about rising rainfall in September.

The Chao Phraya Dam

Still have to keep an eye on receiving water masses from the north.

that affects aggravating the Bangkok area

"Dr. Siam Lawwirotwong" Director of the GISTDA Geo-Informatics Application and Management Office analyzed the water situation with

“The news team penetrated the issue.

Thairath Online" that the cumulative rainfall this year is more than normal.

From looking at satellite images in August

Found flooding in a wide area in many areas.

which if compared to last year

This year there were more floods.

And must watch out for rain storms that increase the amount of water in September.

Large dams are now able to support more water, averaging about 50 percent.

Sirindhorn Dam

Ubon Ratchathani Province

must watch out for the amount of water

Because the water content in the dam is 70 percent, it has to speed up the drainage.

As a result, the area at the end of the dam can be highly flooded.

As for the medium-sized reservoirs, the water volume is full, such as reservoirs in the northeastern region, the north and the upper central region.

If there is more rain from August 23 to 27, the water in many basins will flood the area of ​​the villagers.

“The northern area this week is still at risk of acute flooding.

such as Chiang Rai, Nan, and the upper northeastern region still need to watch out for Chaiyaphum, Kalasin, Maha Sarakham and the Mekong River area.

If more water is released from China and Laos

will cause water to overflow the banks and flood the houses of the people.”

The flooded rice fields in the central region hit hard.

"Dr. Siam" said about the impact of flooding that

With the cumulative amount of rain, many agricultural areas are now flooding.

For example, the areas along the upper Chao Phraya River are Phichit, Phetchabun, Phitsanulok, Sukhothai, where most of the area is paddy.

And if there is waterlogging in the area for more than 5 days, it will cause a lot of damage to the crops.

From this year's flood impact assessment, it was found that

Rice fields, which are fields that receive water

With a total area of ​​about 4.8 million rai, now only part of the rice is harvested.

Therefore, there are many rice fields that have not been harvested.

and if the flood situation enters a critical stage in September

will have a heavy impact on agricultural areas

preliminary from the assessment of flood impacts in the central region

There is a total agricultural area of ​​about a hundred thousand rai.

But now only 50,000 rai has been harvested and if compared to August of last year.

The central region was more affected by the floods than the previous year.

this September

must closely monitor the Chao Phraya River Basin

because of the water situation in the Pa Sak Dam

with continuous acceleration of drainage

as well as the Chao Phraya Dam

Currently, 1,500 cubic meters of water have been accelerated, causing flooding in some areas in the embankment.

But if the amount of water is released from 2,800 - 3,000 cubic meters, it will affect the area of ​​Ang Thong, Suphan Buri, Phra Nakhon Si Ayutthaya.

Bangkok must win the management of the Chao Phraya Dam

"Dr. Siam" continued that the rain continues in the Bangkok area.

causing flooding, water feature waiting to drain

as for the northern water masses that will flow down to join the Chao Phraya

can also manage

But keep an eye on the water management of the Chao Phraya Dam in September.

If there is heavy rain in the area

Must slow down the water released from the dam.

in order not to affect Bangkok

“The water situation in the Receiving Field in Ang Thong, Ayutthaya, Suphan Buri has not yet released more water into the monkey cheeks.

If the northern water mass enters the Chao Phraya River Basin

can also divert water into the area

to prevent flooding in the Bangkok area

At the same time, we have to keep an eye on the water in the Rama VI dam where the water mass will flow into the Chao Phraya dam.”

The likelihood of flooding like 2011 is still at risk.

because if it rains in the high area

together with the northern water mass flowing to join the Chao Phraya River

and the high sea level

This will make it a major obstacle to drain the flooding in Bangkok.

If you look back at the statistics of rain storms that come into Thailand each year, an average of 3-5 children, now Thailand has only encountered 1 storm, which this September.

There is a possibility that there will be more rainstorms coming.

Therefore, we must keep an eye on the storms that will enter the area.

because if the storm comes in contact with each other until it rains for a long time

Must manage the water system effectively.
