Bangkok Floods Persist as Rain Begins to Ease

On September 28, Bangkok said flooding had affected about 329,000 households, or 700,000 people. Rain was easing, but water remained on roads and in low-lying communities. Around 1,500 bedridden patients and others needing care had been moved to hospitals.
Bangkok lies on the flat Chao Phraya delta near the Gulf of Thailand, only a few metres above sea level. Canals, pumps and tunnels move its water. When canals are high, officials must lower them before draining more water from roads and neighborhoods. This staged process means some places clear more slowly.
Rain over the city, water flowing south from the river basin, and high tides can all strain drainage. Buildings cover land that once absorbed water, while subsidence has lowered parts of Bangkok. If rain falls faster than the system can carry it away, water builds up even when the drains still work.
A September 27 report listed floods in 25 provinces, with 174,803 affected households outside Bangkok and eight deaths since mid-September. Special government holidays on September 28 and 29 aimed to reduce traffic. Less rain helps, but canal capacity and staged drainage shape how quickly neighborhoods recover.
