Open Permanent Secretary Thawatchai Kaewganga’s Idea to Solve the Flood Problem The Bangkok-Central region, the whole system, to survive the crisis, comes out of the flood before sinking into the ground
Mr. Tawatchai Kaewkongka Former Director of the Ministry of the Interior Press Operations Center published on facebook Permanent Secretary Thawatchai Kaewkongka on the concept “Bangkok is out of the crisis The central region is sheltered from floods, solving Bangkok’s water problem. Central region that it is time for the country to invest in solving the water problem in the whole system
From 1942 to 2022, 80th anniversary, Bangkok and the central region There have been major floods 8 times, not yet recovered from the crisis, and in the next 8 years, 2030 or 2030, the central region and Bangkok. Sinking into the sea are two major problems that dominate the economic center of this country.
Problem 1. About 8 times, 80th anniversary, Bangkok and the central region There has been a great flood 8 times, one more lesson and one illustration that still can’t find a solution. In 2011 alone, the damage was over 1.44 trillion baht, more than 13.4 million people suffered damage, 69 million rai of flooded areas, 11.2 million rai of agricultural land damaged, 14,000 roads damaged and 7 industrial areas were damaged. GDP contract of 9 percent, or 3.28 billion baht
this damage represents a brake on the competitiveness and development of the country economic recession has lost confidence Country that generates debts indebted farmers If the problem is not addressed in a systematic way, it will lead to infinite losses and damages.
In the past, there were flood statistics in 2 major water metering stations, viz
- Wat Nam Tha Station C.1, Wat Sing District Chainat Province (1905-1959), as the amount of flood water in 1909 (4,383 cubic meters / sec), 1917 (4,775 cubic meters / sec), 1939 (4,410 cubic meters / sec), 1942 (6,500 cubic meters). / sec) Year 1948 (4.420 cubic meters / sec)
Note Bhumibol Dam (1949-1964) Chao Phraya Dam (1952-1957) and Sirikit Dam (1971-1977) to store water for use and can reduce the amount of flood water by 1,100 cubic meters / sec.
- Wat Nam Tha Station C.2, Mueang District, Nakhon Sawan Province ./ s), 1994 (2,539 m3 / s), 1995 (4,820 m / s), 2002 (3,997 m / s), 2006 (5,451 m / s) s) and 2011 (4,689 million baht). m / s)
There is information that the central region and Bangkok It is a lowland area and the passage of 6 main rivers, namely the Ping River, the Wang River, the Yom River, the Nan River and the Sakae Krang River. and the Pasak River which can drain water through the Chao Phraya River at 2,800 cubic meters / second and drain across the west – east coast another 600-800 cubic meters / second, for a total of 3,400-3,600 cubic meters / second to enter the sea Excluding the amount of water flowing through the Sakae Krang River at 500 cubic meters / sec and flowing through the Pa Sak River (supports 700 cubic meters / sec), another 759-11,473 cubic meters / sec, causingThe amount of excess flood water that the Regio Irrigation Department is unable to manage is approximately 2,000-2,500 cubic meters / second.
At present, the government’s approach to managing and solving water problems in the central region and Bangkok Using excavation methods, canals, excavation streams, construction of new waterways to connect to branched waterways and water drainage in fields or catchment areas. Most of which are owned by the villagers and the private sector. The excavation and dredging of the canal are only accelerating the drainage. increase water flow to full potential of the river If completed, it will increase drainage on both the west and east coasts by 1,630 cubic meters / sec., combined with Chao Phraya 2,800 cubic meters / sec., will result in a maximum drainage of 4,430 cubic meters / sec. sec. Up to 13 years, the limit is over 329.151 million baht.
fromThe results of the meeting of the National Water Resources Committee n. 4/2020 and the resolution of the Council of Ministers of 23 February 2021, n. 15, having read and approved. The master plan for flood mitigation in the lower Chao Phraya Basin consists of 9 master plans, consisting of 10 agencies, implementation period of 13 years (2017-2029), budget limit of 329.151 million baht.
Problem 2. As for the next 8 years, BE 2030 or 2030, Central Region and Bangkok going to sink the sea
Photo data from Climate Central clearly indicates that in the next eight years Bangkok will be one of the seven capitals of Asia (Hong Kong, Taipei, Seoul, Tokyo, Jakarta, Manila and Bangkok) to drown, and a preliminary estimate has been made. According to Greenpeace Bangkok and surrounding areas will face a state of drowning at sea AND Thailand will cause economic damage of up to 18.6 trillion baht and will affect at least 10.45 million people and said that over the next 10 years over 96% of Bangkok will be at risk of water. Especially the country’s economic centers such as Silom, Ploenchit and Ratchadaphisek are all affected. including the Chaeng Watthana Government Center parliament building, ministries, offices and departments in Bangkok In 2018 he is Country Director of Greenpeace for Thailand and gave an interview to BBC Thai “If we do nothing Bangkok will be submerged in 10-15 years due to land use and groundwater pumping”.
Although some scholars have argued that the provinces of Bangkok and Nakhon Pathom There will be a possibility of sinking into the sea in the next 8 years is very unlikely. Only possible in the worst case. But if the question is there a chance that it will happen? He answers “yes” to both the Russian-Ukrainian war crisis. Civil war and conflict in the Middle East energy crisis in Europe The number of cars in the world exceeds one billion vehicles and industrial plants worldwide. All of them emit greenhouse gases that affect global warming and melting ice at the North Pole.There is a high sea level crisis and the risk of severe and rapid climate change such as heat waves, droughts and floods if policies, plans, projects and solutions are not accelerated in the central region and in Bangkok. It is inevitable that the city will sink into the sea. And it may take a huge budget to bring the sunken city back to normal.
Examples of successful countries and countries that will solve the problem of the underwater city It can be seen as a way to manage the problem.
one, the Netherlands Once a great flood occurred in 1953 (BE 2496), nearly 1 million rai of land drowned, more than 2,000 people died, Project Maga (Delta Work) was born. Approval after, it takes 5 years, fixes 100 years, can prevent thousands of deaths per year. remove sea water from agricultural land no recurrent flooding cause investments promote tourism
create a good image And with the development of agricultural land, the Netherlands is the second largest agricultural exporter in the world after the United States. Although the area is 237 times smaller than in the United States and 12 times smaller than Thailand. Plan a flood protection system for the next 200 years. It is predicted that by 2100 (BE2643) the sea level will increase by another 1.3 meters and by 2200 (2743 AD) it will increase by another 4 meters. baht in the budget over the next 90-100 years.
Two Jakarta, the capital of Indonesia There is an idea to build a water barrier in the middle of the sea, at a distance of 110 km, with a drainage system in the city. and build a freshwater system with a budget of 185,000 million baht and have an idea to build a floating building, which is 14,000-15,000 baht per square meter.
for the offer for the solution of water problems in the central region and Bangkok, the whole system
With the concept “Bangkok is out of the crisis The central region is protected from floods”.
1. Management of repeated flood problems in the central region and Bangkok The amount of excess flood water that the Royal Irrigation Department is unable to handle is approximately 2,000-2,500 cubic meters / second, despite government approval to implement the Flood Mitigation Principle Plan in the Chao River Basin. Lower Phraya, which has 9 main floors, implementation period 13 years (2017-2029) budget limit of 329.151 million baht. When completed in 2029, it was able to drain a maximum of 4,430 cubic meters / sec, which it is still less than the amount of flood water in 1995, 2006 and 2011 years, therefore, there is an offer forBuild a new river the size or larger than the Chao Phraya River. providing a drainage capacity of 2,500-3,000 cubic meters / second from Chainat province to drain water into the sea in Samut Sakhon province or Samut Songkhram province The new river excavation distance is approximately 300 Km. a great project (Megaproject) in 2 alternatives along the 1st straight (through crowded urban communities Use large budget for land expropriation) or line 2, the curve (avoid urban communities less budget There is better space to build a tank / cheeks monkey) for flood season drainage at not less than 2500-3,000 cubic meters / second, including the maximum drainage potential of 7,000-7,500 cubic meters / second, capable of preventing flooding in the central region and Bangkok at least 50-100 years, ready to build a water storage area (Reservoir / Monkey Cheek) for 4 main uses, namely the use of water for consumption. for agriculture for industry and to balance and maintain ecosystems
2. Guidelines to prevent Bangkok and its surroundings from sinking into the sea According to the non-profit organization Climate Central and Greenpeace East Asia, in the next 8 years, or 10-15 years, Bangkok and the surrounding provinces will sink into the sea. To prevent economic damage that is worth up to 18.6 trillion baht and will affect at least 10.45 million people.

- Therefore, I would like to proposeBuild a sea wallit’s a great project (Megaproject) A distance of 131 kilometers along the coast of 3 provinces, along with a special form of local government organization, the province of Samut Prakan. Samut Sakhon Province Samut Songkhram Province with Bangkokand giveRemove the soil that has been dug into the new stream. The excavation distance is about 300 kilometers to fill the dam, a distance of 131 kilometers.major projects (Mega Project). Both projects benefit each other. and can prevent floods The high seas have sunk the city. systematically in the central region and in Bangkok and ready to build drainage systems and fresh water systems in cities / provinces to go together
