Khunying Sudarat Keyuraphan lists three critical shortcomings to address from Bangkok’s 2026 floods: unclear warnings, delayed public assistance, and failed water management. She recommends using these as lessons to prepare for future major floods.
On 1 October 2026, Khunying Sudarat Keyuraphan posted on Facebook about the flood situation, outlining a checklist of issues to fix from the 2026 Bangkok mega floods. The article aims to propose solutions and prepare for future major floods in Bangkok. She draws on her experience managing flood problems in Bangkok from the severe 1996 flood through 2006, when she oversaw the Royal Irrigation Department.
Khunying Sudarat stated: 1) Did government warnings pass the test? Warnings should not be mere notifications but clear messages informing people what is happening and what they must do, straightforwardly. Warning duties lie with two agencies: nationally, the Meteorological Department should stop broad alerts, while locally, Bangkok—knowing the terrain best—must specify which areas, villages, or low-lying basins like Kheha Khlong Chan, Kheha Romklao, Kheha Ramintra, as well as old villages and canal-side communities, are at risk. Bangkok must tell residents in these basins to immediately move belongings and vehicles to higher ground to reduce damage. If such warnings had been issued this time, damage—especially to cars—would have been far less.
2) Has flood management repeatedly failed? The chaos I witnessed and the media showed remains unchanged, similar to Hat Yai: delayed, uneven assistance to residents, with most donated food piled only at the front.
A large War Room and local War Rooms must be established, appointing incident commanders at both levels with authority over all involved agencies, even across ministries, plus power to approve appropriate emergency budgets to swiftly aid the people.
They should also manage incoming aid from various sources to ensure it reaches those in need efficiently, while reporting real-time situations to the central War Room. This allows the highest commanders to have accurate, timely information to solve problems and assist the public.
Khunying Sudarat said: 3) Is water drainage management effective and vigilant? We were "lucky in misfortune" this time, facing only one problem: heavy rainfall in Bangkok. So, after meteorological warnings, did Bangkok fully drain all major canals before the rain? How much water was drained? Are the seven giant tunnels, built at a cost of hundreds of billions, functioning efficiently? What main issues prevent these tunnels from reaching full capacity? Has Bangkok prepared enough pumps to remove water from basin areas and canal-side communities like Kheha Khlong Chan, Kheha Romklao, and many scattered old housing estates? Otherwise, these areas would remain flooded for weeks even after rains subside. Has Bangkok used its significant technological investments for flood modeling and prevention sufficiently?
Khunying Sudarat said she invites reflection on these shortcomings to serve as lessons for effectively managing the next mega flood. Because Bangkok residents will face major floods multiple times in the near future, we must prepare thoroughly to minimize public hardship.
