Country ‘better prepared’ to handle flood hazards, making a repeat of 2011 highly unlikely.
Experts predict that this year’s flooding will not approach the catastrophic levels experienced in 2011, thanks to decreased water volumes coming from the north and improved disaster readiness. Recent assessments indicate a marked decrease in water flow, with current estimates showing 15.6 billion cubic meters passing through Nakhon Sawan compared to 23.4 billion cubic meters in September 2011.
This decline in water volume has been attributed to the reduced contributions from northern rivers, as only the Yom River has significantly impacted this year’s levels. Comparatively, the water flowing through Nakhon Sawan on August 25 was around 40% of the amount recorded in 2011, which experts deem manageable.
When addressing concerns about potential flooding in Bangkok, it is suggested that current volume levels indicate minimal risk. Bangkok’s unique geographic position as the exit point to the sea further mitigates the chances of a severe flood, given that the water impact from the north is not extensive.
Confidence in localized water management systems, particularly the 10 “monkey cheek” reservoirs along the Chao Phraya River, also bolsters flood prevention efforts. These catchment areas possess the capacity to hold 1.2 billion cubic meters of water, serving to redirect potential flooding away from the capital.
While Bangkok struggles with surface water drainage during heavy rainfall — especially in areas known for flooding such as Chaeng Watthana Road and Ratchadaphisek Road — the structural improvements made across the city have bolstered its resilience to flooding events.
Nonetheless, global warming remains a critical factor influencing weather patterns, with last year seeing an alarming spike in rainfall leading to severe flooding. Predictions suggest that continued temperature increases could exacerbate future flood risks, with projections of a 75cm rise in sea levels in the Gulf of Thailand over the next 26 years, potentially submerging parts of Bangkok.
Experts urge awareness of these climate challenges, emphasizing the importance of preparing for increased rainfall and the potential for future disasters linked to rising global temperatures.
