Inner Bangkok passes danger point

GIS expert Dr Anond Snidvongs in a daily NBT flood analysis noted that innner Bangkok has passed danger point as today is the last day of high tide.

Bangkok North sees reduced water volume at Khlong Rangsit, Bang Pa-in.

Present flood in Laksi and Khlong Prapa resulted from leaks. Government is erecting new barrier at Lak Hok.

There is no more danger from water mass from the North. In the next 3-4 days, high tide will be significantly less and government/BMA can drain even more water which will see flood level in Rangsit decline slowly.

BMA tries to divert floodwater from Don Mueang and Phaholyothin through Khlong Lat Phrao and Saen Sap.

Floodwater from Lak Si will be absorbed at Khlong Bang Khen and will not reach Chatuchak area.

If new barrier at Lak Hok is finished tomorrow, flood at Chaeng Wattana will stabilise and gradually dry up.

Government will try to protect Khlong Prapa from floodwater.

Irrigation Department must finish all breached sluice gates/walls along Chao Phraya river so that all the flooded areas in Nonthaburi can be siphoned off to Chao Phraya river. This should be finished before Loy Kratong.

If a few leaks in the North are fixed, Chaeng Wattana can be dry within one week.

Lat Krabang, Nong Chok, Minburi were originally planned as floodway to be drained off. But this no longer work as people settle there and object to rising water.

To placate angry residents, the government decided to raise sluice gate at Khlong Samwa but this would pose threat to Khlong Saen Sap residents. Expect to see rising water in low-lying areas. But this would not pose threat to industrial estates.

In the next few days, Froc has to be careful about Bangkok North and the west. The west still sees rising threat while the North and East pose less threat.
