\"SINGAPORE: National water agency PUB explained that the flash floods on Sunday morning were caused by two bouts of heavy rainfall.... PUB chief executive Khoo Teng Chye said he is studying some possible solutions to prevent future occurrences.... \"But given Singapore's built-up situation, these are very, very expensive schemes.\"...
\"Personally, I think our weather has changed. I'm actually psychologically prepared for it to get worse,\" Dr Balakrishnan said.
\"You're dealing with nature, and you're dealing with the weather; you have to be prepared that there is a limit to human engineering and what we can deliver.
\"But having said that, let us make sure we have done the best we can and within those limits, then cope with whatever else that nature throws at us.\" ...\"

Their explanation like no explanation... basically tell us to prepare for worse?
Pls lor... if our human engineering cannot prevent flooding... then don't even think about nuclear....

1. somebody has quoted this phrase before during the orchard road flood
2. then ask Singaporeans to study engineering is giving them 'dead road 1 way'

it seems like the floods happen after the barrage was built and put in operation? maybe they need to do someth abt pumping the water out of the enclosed area at a faster rate?

means our human engineering aka barrage is fail lor... they shld remove the flood control writeup from their 3-in-1 benefits....

is orchard a low-lying area? the previous lucky plaza flood they said it was due to some major drains clogging up right? i thought they would have cleaned it by now...

I don't believe a thing they explained the flood.


1. These flood problems suddenly burst into the national scene in the last 18 to 24 months. Why so sudden ?

2. Vivian Balakrishnan's idea of the weather / climate change that is the root cause of the flood is really treating his voters as idiot. If I see him face to face I will tell him to his face this is rubbish. I accept global warming, but suddenly in the last two years it became so bad all of a sudden ? PM Lee better be reading this.

3. I saw the overflowing canal outside Swiss Club Road / Turf Club / Bukit Timah / Dunearn junction. Right after the Sixth Avenue junction further down along NYGH, the drain wasn't overflowing. WHY ?

4. Duchess / Princess of Wales near SPC station, NYPS Gate B / Lutheran Road was flooded but Kheam Hock Road / NUS was not. WHY ?

5. Why Balmoral / Bukit Timah / Newton not reported to have flood ?

and this morning in the drizzle so many workers were see clearing the run-ff drain along Lutheran Road (not the big drain)

somebody still not doing their work

maybe we are really sinking with those tunnelling and new constructions going on everywhere :evil:

[beardpapa80]

i dont think is climate change oso.


and i don think with current technology they can be ‘caught surprise’ by heavy rainfall. they could have given ample warning in advance to potential affected areas at least damage wont be so bad wad.

In the past we used to have rains for 3-4 days still no floods now even if it rains for few hours can flood oredi :? is it climate change?

I think the sudden downpour seems much heavier nowadays.

I supposed if it is raining continuously for 3-4 days, the draining away of the water might be more manageable than a sudden heavy downpour whereby water do not have enough outlets to be drained away effectively within a short period of time.

[pinky]

I read an article before explaning that as more buildings are built, there is less space for water to be drained away so floodings become more common and occuring in big cities also.

If you talk to friends or people who know engineering and flood control,

you will realised that someone somewhere has not learn their lesson and
become complacent and it alway somebody , anybody and someone else
job to make sure nothing like happened again - this can be prevented.

Engineering will tell out it can be done - no question about it-
in simple terms -it will cost money because the designed
drainage and pump system only cater for a certain level
of water ponding therafter it will not take in the water
- multiply by a certain factor of safety and occurances,
who pay for it the building owner or tenants/buyer?

Also these call for a change in the standard of drainage requirement
in flood prone area and they need to study it and map out the area
and not run the water into the neighbours.

Looking at this flood , it look to me the fooding also encroach into the
neighbouring places that did not get flooded in the last rainfall :?
so they solved this and create the next flood zone , :imdrowning:

We each wait for our turn to be flooded :spank:
