Recent Floodings must be linked to the Marina Barrage

[kojakbt]

For the many years, I never recall we have any serious floods in Singapore until the completion of the Marina Barrage.

Actually, common sense will tell you that Marina Barrage will definitely have an effect on drainage. Just look at the pic below. The Marina Barrage is acting more like a dam. Hence, the water level on the barrage side is definitely higher than the usual sea level (on the left). And since major canals will drain water towards Singapore river and Kallang basin and finally exit at the barrage, with higher water level at the barrage now, the water drainage will be slower than before.

I understand that the barrage also have emergency holes below to allow for faster drainage of water into the sea to prevent flooding upstream. There lies the challenge -> in the design of the Marina Barrage, did PUB take into account of these "once in 50 years" rains? That means to say, are the holes at the barrage big enough to allow for fast drainage of water out to sea in case of these "once in 50 years" rain??

Obviously, no. And we pay millions for this. It's an expensive joke.
