After hours of continuous rain, flooding in Bangkok and surrounding provinces caused chaos on the roads. Several traffic accidents and long traffic jams were reported.

Sathon, Bang Rak, Phaya Thai and Khlong Toey and most parts of Thon Buri were particularly affected. But things also went wrong with Don Muang, Sai Mai, Bang Khen and Lad Krabang.

A whopping 164,5 mm fell in the Bang Khae district. Phetkasem Road in Bang Khae and Ekkachai Road in Bang Bon experienced flooding. Part of a highway Sathupradit Road was also flooded.

The rainwater on Chan Road in Sathon district and Charoen Nakhon Road in Khlong San district caused many traffic problems in the area.

The downpours also caused problems in the surrounding provinces of Nonthaburi, Samut Prakan and Pathum Thani.

More summer storms are expected, according to the meteorological service. these bring heavy rains, gusts of wind and hail. The northern, northeastern, eastern and central regions, including Bangkok and the surrounding area, will be affected until Saturday. The weather is under the influence of a high pressure system from China.

    Well,

    It is getting better and better at absorbing such "pour" showers. Very large cellars are made, in various places under the road surface. For example, Rangsit (Bangkok), near the Big-C, was always under water with its shower, but thanks to that basement, not anymore. Also at Don Muang they are building his big cellar.

    Woke up yesterday to a heavy downpour that lasted until around noon. Very cloudy all day, even now and it was very cool last night-like in December.

    It remains astonishing that after so many decades of flooding with a bit of a serious shower, people still do not work on a large scale to maintain the sewage system (if present) better and more regularly.
    The construction of a few underground cellars is an emergency measure. After all, with 2-3 of these showers, the cellars overflow.

    The maintenance and improvement of sewers must take place all year round and not only be cleaned at the time of a shower or during the rainy season. The costs of this on an annual basis will probably be lower than the damage that now and again occurs in the event of a flood.

    But… I have no illusions that people will actually do that. It keeps sticking a plaster here and there and with many males / females showing on TV, who are sweeping, emptying overgrown khlongs here and there manually or "painting" a bridge (over the growth etc of course).

      It is absolutely not surprising that the streets in Bangkok (and elsewhere) are flooded for several days a year.
      As mentioned in the article above, 160 mm of rain fell in a few HOURS in some places. In the Netherlands, an average of 800 mm of rain falls per YEAR (!!), and the chance that more than 100 mm of rain falls in a few hours occurs in the Netherlands only once per century and therefore leads to flooding, and in Thailand that is a number of times per year.
      So it's a bit more than a little serious mood. No sewage system can withstand this kind of amount of water, period. Improvements will somewhat limit the number and duration of flooding, but they will never be able to prevent it completely. Your derogatory remarks in your last paragraph make no sense.

        And with this subject, the key question is what outcome the cost-benefit analysis gives. In other words: how much must be invested in water management to keep the economic damage and the number of deaths at an acceptable level.
        I believe that in the Netherlands that analysis resulted in one flood every hundred years.
        It seems to me very unlikely that a cost-benefit analysis for Bangkok would show that a few floods per year cause less damage than the costs of preventing them.
        If the floods cannot be prevented with well-maintained sewers and canals, other ways must be ensured that the flood frequency is drastically reduced by a factor of 300(?). I am thinking of overflow areas, water storage cellars and ensuring that rainwater can enter the ground as much as possible, which is also good against soil settling.
        Furthermore, reforestation around (the upper reaches of) the rivers would significantly(?) reduce flooding in the lower reaches. Forestry instead of rice cultivation?

      You cannot reasonably make the sewer system suitable for heavy tropical showers. Just as we in the Netherlands cannot make our rivers and their dikes suitable for periods when it has rained a lot in Germany/France. What we have done: Created and/or designated flood areas. Very similar to a basement. They are not that crazy in Thailand.
      What is a problem is that an increasing percentage of the urban area is being built on or asphalted, so that the water can no longer penetrate the soil and the amount of water to be drained off artificially continues to increase, even if the amount of rain remains the same. So cellars will still have to be added for the time being.
