Bangkok Governor: Brace for Possible Flooding

The Bangkok governor has ordered Bangkok Metropolitan Administration officials to arrange sandbags and temporary evacuation centers in preparation for possible flooding.

Bangkok Governor M.R. Sukhumbhand Paribatra says he has ordered city officials to arrange sandbags and coordinate with district offices, temples, and schools to be utilized as evacuation centers if the city is hit by floods.

Sukhumbhand expressed concern for 1,200 households living in 27 riverside communities outside the dike-protected zone.

The governor noted that the Bangkok Metropolitan Administration or BMA will closely monitor the flood situation until November.

The Bangkok governor added that the efficiency of the city's water drainage system has doubled this year.

The current construction of three additional dranage tunnels will increase capacity even further.

Regarding flood-prone areas such as Ratchadapisek Road in front of Robinson department store, Sukhumbhand said the Drainage and Sewerage Department has constructed a sump, which will be able to pump out water at a rate of four million cubic meters per second.

The construction is expected to be completed in one month.

The Bangkok governor added that the water level in the Chao Phraya River is currently not worrisome.

Floodwater flowing from the North to the river is flowing at a rate of 1,300 cubic meters per second.

Protective dikes erected by the municipality are able to hold back floodwater to a height of 2.5 meters.

Somehow I doubt that!

I doubt it too, that is significantly more than Niagra Falls manages.

Old information but more realistic numbers:

Climate Change Impact and Adaptation Study for Bangkok Metropolitan Region Final Report capacity.

Pumps

Results from the simulation study reveal that in the future the pumping system in the eastern area

of the Chao Phraya River will have enough capacity to cope with repeated flooding. On the other

hand, the pumping system in the western area of the Chao Phraya River will not have enough.

The pumping stations at Phasi Charoen and Sanam Chai should be upgraded to capacities of 400 and 200 m3/sec for floods of a 30-year return period (550 and 350 m3/sec for floods at a 100-year return period) respectively. These two pumping stations will drain the flood water inside the protection area into the Tha Chin River.

The pumping station at Klong Khun Rat Phinit Chai should also add capacity to reach 100 and 250 m3/sec for floods at a 30-and 100-year return period respectively.

However, drainage canals to convey the flood water from the inundated area to the

pumping stations have to be trained. The unit costs of pumping station and drainage canal

improvement were derived from the study results of the drainage system improvement in the area

around Suvarnabhumi Airport (RID, 2004).

Don't know about the specific area reported in OP.
