People in Bangkok are getting a bit jittery about a possible flood threat (several streets have been flooded for a couple of hours after heavy rainfall). People are building floodbarriers around Bangkok.
But as Bangkok Pundit pointed out:
Major reason 4 severe sustained flooding in 2011, was not just months of excess rainfall, but large amount of water released from dams.
In 2012, because of better management of water in dams, they r able to significantly reduce the discharge of water during monsoon season
For Sirikit Dam, in 2011, 45 million cu/m of water was discharged per day for Sep1-Nov1. For Sep1-19 2012, we r down to 4 mcu/m per day
For Bhumibol Dam, in 2011, 44 million cu/m of water was discharged per day for Sep1-Nov1. For Sep1-19 2012, we r down to 3 mcu/m per day
These r the two largest dams so u can see that reducing the discharge of water reduces water flowing downstream. Of course, we r still
going 2 have flash floods when there is excess rainfall (as in Bkk recently) over short period of time, but rain stops, water drains away
Obviously, we need to keep an eye on the weather, but BP stills see no signs of a severe flood approaching 2011 levels
