Bangkokians on Friday were warned to prepare for flooding in the middle of this month when water from upstream flowing into the Chao Phraya River will coincide with high tides.
Bangkok Governor Sukhumbhand Paribatra gave the warning during an inspection of the water situation along the Chao Phraya River and Bangkok Noi canal.
Some 200 households in riverside communities outside the city’s flood prevention dykes have been already been hit as the period of high tides approaches and river levels from upstream water flows increase.
Sukhumbhand said the construction of 86 kilometres of dykes along the Chao Phraya River is almost complete. Only 700 metres remain unfinished pending negotiation with local residents and private companies who own the land.
The governor said today's level of water in the river stood at 1.60 metres above mean sea level, which is still not too high, while water from upstream being released into the capital is flowing at 2,300 cubic metres per second.
He said Bangkok can handle water flow of up to 3,000 cubic metres per second.
However, the governor expressed concern for 850 households in 25 communities living outside the BMA dykes, noting that they would be affected by high tide and the flow of upstream water between October 1517. The Chao Phraya River level may reach two metres above sea level.
Officials in 11 atrisk districts have been asked to prepare to provide help for residents.
