Better model to predict floods likely in the near future
It will include 3-D land-height map of Marina catchment area for a start
Published on Jan 21, 2012
National water agency PUB could be using a better flood-prediction computer model in the near future.
It will include a 3-D land-height map of just the Marina catchment area for a start, to predict the direction in which rainwater will flow at ground level during storms, and where flooding might occur.
Such a map, which the PUB has commissioned, will depict land height in that area to within 10cm accuracy.
Computer models now in use only predict how rainwater flows within drains and canals, and the intensity of rainfall they can handle.
So it seems that no detailed studies were done on the catchment area that resulted from the new Marina Barrage. So how can it be claimed by the authorities that the barrage did not cause the “once in 50 yrs” Orchard Rd floods. They occured twice in two months in 2010. And late last year, parts of Orchard Rd were “ponded”.
No wonder this news came out on a day when S’poreans were at the start the CNY hols? It was a gd day to “pond” the news? So did the same PR people who advised the use of “ponding” advise releasing the news on a day it would disappear without trace? If so, VivianB should kick the PUB’s new CEO again, juz as he did over the use of “ponding”. [The last two sentences were only added at 9.00am, hrs after the original posting.]
BTW, the “50-year flood” minister (“Speak to me in English” Yacoob) is now in charge of taming the Internet Tsunami. Can’t solve “ponding”, so moved to handling a tidal wave. Taz meritocracy S’porean-style? He is also a poster boy for a “sacrificing” minister. He was an associate professor at NUS earning at most couple of $100,000. He then became junior minister, with a starting salary of abt a million. Wow some sacrifice!
