Bangkok flood worse case scenario

Wednesday morning I posted the worst case scenario which was confirmed now in the evening at a Thai local TV station. Now it is not anymore the worst case scenario but it is something that is going to happen in the next hours in Bangkok. Simply said, they tried to stop the water which was not the smartest idea as now there are 4,000 million cubic meters of water running down towards Bangkok city!

The worst case scenario in regards to Thailand and more exactly Bangkok flooding in 2011 is illustrated in the below graphic. So far various areas of Bangkok are already flooded like Don Muang, areas around Chao Phraya river, around Grand Palace and more. There are no floodings in central Bangkok yet (as of 26 October 2011).

Bangkok blooding - worse case scenario 2011

Prime Minister Yingluck Shinawatra warned Bangkok residents in all areas last night to brace for flooding after advancing runoff from the north of Bangkok surged into Don Mueang airport yesterday.

In addition to the scenario presented above, the real situation map is right below in the illustration. 

Bangkok flooding situation - 26 October 2011

Khlong Hok Wa flood barrier is one of the two major barriers that block floodwater runoff from Pathum Thani from surging into the northern part of Bangkok. The other barrier is in tambon Lak Hok of Pathum Thani which connects to Bangkok's Don Muang district.

Floodwater destroyed some earth dykes near Lak Hok flood barrier raising concerns over pressure from a huge volume of water flowing into the city.

Don't forget to drop a note if you have any comments.

Bangkok flood warning for 6 districts

The Metropolitan Waterworks Authority has urged Bangkok residents to store tap water for use during the flood crisis.

The dyke along the MWA's Khlong Prapa canal had broken, allowing overflow from Khlong Rangsit to flow into Khlong Prapa, which supplies drinking water for the Bangkok city.

"Still, Bangkok residents should store tap water for use as the flooding this year is worse than expected," he said.


The Bangkok Metropolitan Administration late Sunday issued a warning for people in six districts to prepare for flooding as the huge amount of water from the North continues to bear down on the capital.

The six districts are Don Mueang, Lasksi, Bang Khen, Chatuchak, Bang Sue and Sai Mai.

Bangkok Governor Sukhumbhand Paribatra warned residents to remove their belongings and cars to higher ground.

The Nonthaburi high amount of water is to arrive in Bangkok in the next several days. Residents in western Bangkok and adjacent districts of Nakhon Pathom face a challenging week, with massive run-off heading their way from Nonthaburi.

The flooding and disaster situation map as of 24 October 2011 is right below;
