The flood situation in many areas has not yet been resolved and the smell is beginning to signal a tendency to face heavy rainfall continuously throughout the month.

Sep.–Nov. 2022

Caused by the powerful ejection of La Niña hit the iod phenomenon, high sea temperatures in the Indian Ocean.

and there is still a chance that the storm will come in again during this period

become a boost to

“Thailand still has more rainfall than the normal average”

aggravating the risk of flooding economic areas.

both agriculture

And the industrial sector can cause damage to the end of this year.

Assoc. Prof. Dr. Seree Supharathit,

director of the Center for Climate Change and Disaster, Rangsit University

According to the forecast 15 days in advance,

"Thailand"

has begun to signal the risk of being affected by

"Influence of the storm during the 3 months from Sept. – Nov. 2022"

in what intensity will the storm be?

or the direction of moving into that region

"Need to forecast 7 days in advance again" to know the exact amount of rainfall

Roughly

, "this year, there will be 23 storms"

. In the first half of the year, 8 occurred and there are still 15 left. In this number, no one knows that.

"How many children will enter Thailand?"

But on average, every year, they will enter 2-3 children. As such, they must be prepared to defend themselves to have a water support as well.

If

it rains over Bhumibol Dam

or Sirikit Dam”

, this should not be a problem with 2 dams still able to support water.

"Unless it rains under the dam here, there will be a big flood problem"

and will also affect the Chi River basin.

and the Mun River basin may aggravate the flooding

because now the amount of water in two places has already overflowed the banks

Initially, the Chi River basin overflowed its banks in Khueang Nai District, Mueang Ubon Ratchathani District.

The river basin overflows the river bank.

Phibun Mangsahan District, Warin Chamrap District, Sawang Weerawong District

Ubon Ratchathani Province

As for the solution for flooding, there are also

obstacles

.

“Some people”

refused to accept because they had to expropriate the land.

The next effect is

"Chao Phraya River Basin"

Currently, the water level is quite high, observed from September 18, 2022.

The "Chao Phraya Dam area"

drains at 2,000 cubic meters per second.

Compared to the same period last year, the drainage was 1,200 cubic meters per second.

And the most draining period is on October 20, 2021, amounting to 2,800 cubic meters per second.

This figure shows

"Big flood risk"

with the amount of rain will peak in the range per month.

Sep.-Nov. 2022

The main factor comes from

“The amount of rainfall caused by the storm line” may shift into the central region.

causing the full amount of rainfall to flood the fields and flood into the central region

then gradually descended into the lower central region in the economic area respectively

This is different from 2011, when the dam was released into the Chao Phraya River basin until the river bank overflowed and flooded the central region. Therefore, this year, the Chao Phraya Dam drainage had to be adjusted from 2,000 cubic meters/second to 2,800 cubic meters/second. or not

to bring some water into the monkey cheek area in Bang Ban District, Sena District, Phra Nakhon Si Ayutthaya Province

According to the government's talks with the people since September 15, only need to divert as appropriate without affecting the occupation, farming, farming because taking water from one place to collect another.

would affect those livelihoods.

The “government”

may also have a remedy.

Reinforcing that

"this year the risk of flooding depends on rain"

The most worrisome situation was in September because it was the wettest period in the upper central and northeastern regions and the last week of this month.

"Maybe a storm"

results in heavy rain spreading widely in almost every region.

which increases the risk of causing a large flood

Of course, this

“over-normal rainfall”

has all been influenced by the negative impact of La Niña on the IOD phenomenon.

Causing sea temperatures on the east coast of the Indian Ocean to be higher than the west coast, and high humidity has been a key driver of rainfall since September-November.

and it fell 20% heavier than last year, so it's a sign that

"This year, the water comes more than the year 2021"

for sure. "People living along

the

canals are more at risk of being affected than those who live far away from that river."

near term

Next, the trend of

"Northern water flows into the central region"

according to the northern water principle is divided into 4 streams, namely the Ping River, Yom River, Wang River and Nan River.

“During floods, they often have to be released into the Chao Phraya River to push into the Gulf of Thailand,”

causing the Chao Phraya River to have high water levels.

until having to divide the water to the Tha Chin River

and the Little River

but now found

"Tha Chin River"

has high water levels, overflowing the banks, partially inundated in Suphan Buri province, forcing to reduce the discharge from the Chao Phraya River near the Phon Thep floodgate to 20 cubic meters per second.

Despite the reduction in drainage, the Tha Chin River, Suphan Buri Province, has a water level of 200 cubic meters per second, which is rainwater falling into the Tha Chin River.

This has become a concern that

"If this period rains 300 millimeters above the Chao Phraya dam as in 2021,"

the flooding in the central region that is facing flooding will not be more severe than last year.

Something to keep an eye on is

"In the future, the intensity of rain tends to get heavier"

with global temperatures rising every day.

“Create more rainfall than the average in each rainy season”

, originating from climate change (Climate Change). Greenhouse gas emissions cover the earth, trapping heat from the sun.

At the same time when

“The amount of rain increases” in

the future, the area that will be used to support the water retention will decrease.

“Used for commercial use to create value”

as the city grows

and there are more structures blocking the waterway

As in the case at the beginning of September 2022

, "Bangkok has just encountered 100 years of rain in heavy rainfall for a long time"

causing flooding in many important areas.

reflect that

“Rain behavior is difficult to predict.” This is becoming a concern for even more water situations in the future.

Then another data from

"NASA"

, the latest in June 2022, global temperatures have risen from 50 years ago, for example.

Europe has a temperature rise of 5 degrees Celsius, Korea 3-4 degrees Celsius, resulting in an increase of 30% of precipitation. Thailand has a temperature rise of 2 degrees, with 20% more rainfall, because for every 1 degree Celsius, there will be 7 more water in the atmosphere. % waiting for the day to fall

Therefore, this led to an event.

"Korea has heavy rain" and that is all caused by climate change, causing everything to collapse like more and more disasters.

In this way, what we can do is that "Thailand" must be prepared for the change of rain water all the time.

"Don't think that waiting for the northern waters to flood and then there will be a risk of flooding like in 2011" because that nature would be difficult with different flooding behavior.

Therefore, this year the floods will come from rainwater flooding the fields, flooding out mainly economic areas.

“We should not link the present to what happened and stick to the past flood events.

Because the water situation has changed, it can happen in any way, for example, in 2021, the flood in Sukhothai that is expected to rain in Phrae province flows through Si Satchanalai district to Sukhothai, making preparations to cope well. heavy,”

Assoc. Prof. Dr. Seree said.

When this is the case, the "government"

defense

may also need to be assessed.

"The way of the scene

or assumptions to simulate water situations in advance in many ways”

in order to provide an answer to a rough visualization of events

Then use that information as a model for coping with the water situation each year.

and always inform the public in advance

Finally, leave it

"This year the rain hasn't stopped raining"

need to follow

the "storm"

that will begin to take effect in the month.

Sep-Oct, causing the northern, central, eastern and northeastern regions

There may be more rainfall

and after 8 Nov.

"Upper South"

is at risk of encountering a lot of water, so we have to closely monitor the rain from the storm.

and reiterated that "from 2023 onwards" Thailand will enter a drought mode for 4–5 consecutive years that will raise water scarcity more and more, especially in 2024-2025, the drought situation will be the most severe. “So don't forget to manage your water in case of drought.” It is not the same year-to-year use of water as it is now.
