Floods began threatening in Bangkok in September and October. Public officials knew it was coming. But there Bangkok Gov. Aswin Kwanmuang stood before the media Monday, apologizing after the Chao Phraya River overflowed its supposedly fortified banks.

The city Drainage and Sewerage Department reported overflows from river-connected canals in Bangkok and Muang District of Samut Prakan, blaming it on high tide.

At about 10 a.m., the department reported flooding in Bangkok Noi, Taling Chan, Bang Khunthian and Nong Chok districts of the capital. In Samut Prakan, flooding hit Muang District and areas along the Samrong Canal as well as a khlong in the Bangpu Recreation Center.

Inspecting flooding on Song Wat Road in Samphanthawong District, Aswin said the high tide and surge from provinces upstream over the past few days raised the level of the Chao Phrya to 2.3 meters and communities standing without a permanent embankment were flooded.

He said the Bangkok Metropolitan Administration had placed sandbags to protect the communities but the level of the river was 50-60 centimeters higher than expected.

As a result, the river overflowed into many areas including Song Wat and Ratchawong roads in Samphanthawong District, other areas in Bang Phlad, Charoen Krung and Rama III roads in Yannawa District and Charoen Nakhon Road and Bukkalo intersection in Thon Buri District.

“BMA must apologize for the overflow into areas by the Chao Phraya River today which affected the everyday life of people and caused traffic congestion in many areas. Floodwater is receding, the governor said.

City hall earlier said that the Chao Phraya flowed at the rate of 2,524 cu. meters a second past Bang Sai District of Ayutthaya but claimed the discharges did not cause flooding in Bangkok and Samut Prakan but the high tide did.

“Officials are monitoring the situation and have placed sandbags in flood-prone areas to cope with the evening high tide from 4pm to 7.30pm and the high tide tomorrow morning,” Aswin said.
