The Bangkok Metropolitan Administration has confirmed the city is fully prepared for rising water levels, insisting there will be no repeat of the 2011 catastrophic floods.
Bangkok governor Chadchart Sittipunt has assured the public that the city is geared up to handle the combined threats of northern runoff, high tides, and heavy rainfall, saying that current water levels are significantly lower than those during the 2011 floods.
During a river inspection with media crews, Mr Chadchart reviewed flood prevention measures along the Chao Phraya River, including sandbag barriers, leak repairs near Rajini School, and embankment reinforcements near Wat Rakhang.
He confirmed that Bangkok is coordinating closely with the Royal Irrigation Department, National Water Command Centre, and Office of National Water Resources.
As of Oct 6, major dams in the Chao Phraya Basin — Bhumibol (89% full), Sirikit (96%), Kwae Noi (100%), and Pa Sak (73%) — still have capacity to hold a combined 2.04 billion cubic metres of water.
Flow rates at key stations remain below critical thresholds, with C.298 in Pathum Thani recording 2,421 m³/sec, far below the 3,930 m³/sec seen in 2011.
High tides between Oct 9-12 may raise river levels, especially in low-lying areas, but are not expected to breach permanent flood defences.
Rainfall from Oct 6-14 will be influenced by weakening low pressure from Tropical Storm Matmo and a shifting monsoon trough, bringing scattered heavy rain to Bangkok and surrounding regions.
Bangkok has implemented vital strategies. For northern runoff and tidal surges, there will be a regular inspection of flood barriers, and emergency response teams will be deployed to monitor the flood situation.
Other measures involve lowering canal levels, preparing drainage systems, and mobilising equipment and personnel.
The city has reinforced 80km of permanent flood barriers and addressed 22 of 32 vulnerable “gap zones”, with sandbagging completed at 75 locations using 198,700 bags and 1,656 m³ of sand. Mobile pumps and 24-hour monitoring teams are also in place.
For 320 households in 11 communities outside flood barriers, district offices have provided sandbags, temporary walkways, and emergency support.
“We’re confident in our flood management systems. This year’s situation is under control and nothing like 2011,” Mr Chadchart stated.
Meanwhile, the Thai Meteorological Department forecasts continued rain across northern, northeastern, eastern, and southern provinces, with warnings for flash floods and waterlogging due to accumulated rainfall and rising river levels.
Cooler air from China is expected to signal the transition to the early winter season.
