Could this be the cause of flood in Singapore?

[rusty]

Whatever the soil condition, whether compacted or made impervious by waterproofing compounds, a properly designed piece of engineering work would have all these taken into consideration and a once in 50-year event will only happen once in 50 years and not 3 to 4 times a year.

No amount of engineering could prevent a flood says the sly old man...it should have been no amount of scholar has the in-depth knowledge and understanding of correlated behaviours on the oceans, the seas, channels, straits, rivers, canals, tides, soil conditions, soil compositions, water tables, water pressure, underwater current, weather conditions...and much more... only God knows.

Mechanical and electrical engineering are easier to manage and design with precisions because there are constants you can work with whereas the former has a lot of unpredictable variations. Civil engineerings are sometimes caught off guard by earthquake and tsunami.

Soil alone is not the main cause to flood...it is a combination of those unpredictable variations mentioned earlier that is puzzling.
There is also a possibility Singapore sea level has reached an equilibrium and I strongly believe we have, due to the massive land reclamation.

The 3 to 4 times flood in a year you mentioned could have coincided with the heavy rain and laying of the tunnel across the river mouth coupled with other inherent attributed to over compacted ground, too much buildings, drainage problems, water displacement, marina barrage and God knows what.

My hunch is marina barrage and the underground tunnel across the river mouth is the last straw.
Just hope that fucking old man is weak enough to live longer and witness some of his failures and be fed the same medicine he shafted.

a lot of civil engineers in this forum LOL

bro,
me only a noob at best, a combat engineer at worst :p:p:p

They make more sense and provide more credible hypothesis for empirical testing than the 1-liner statements by the official clowns.

thank you, kind Sir!

bro,

suddenly it dawned upon me that the area around ION and around the MRT, the tunnels were to be water-proofed as well, right?

are we able to draw a correlation to the dates of construction to the dates of the flooding at Orchard?

imagine having more data on amount of rainfall per hour collected over that few incidents of flooding

 

[zhihau]

hmm... did the amount of rainfall hit the desired rate this morning to test the hypothesis?

Difference between a scientist and an engineer is that scientist uses exact figures, an engineer uses approximation.

Granted there could be complex factors affecting the outcome but these can be summarized to show its worst impact e.g. the max. amount of rainfall, the highest tide, the strongest wind, the greatest water flow through the channels, the degree of water absorption (test has to be done), amount of possible congestion (again has to be determined by observation and controlled by maintenance) etc etc.

When taken together, a fairly good picture can be obtained and a plan worked out. The problem is some factors are assumed to be unchanging and no one bothers to revisit the calculations. Remember the independent panel found the drainage to be inadequate. In fact such a conclusion can easily be obtained internally but did anyone bothered?

Engineering calculations are silly because after the laborious computation, they will multiply the result with a safety factor. So I guess most of those locals involved are fully aware of the problem. The issue is that no one dared to tell the truth that it is not viable - in view of its initiator and the commitment given by the management that it is viable. The young gutsy ones will probably leave if made to endorse the plan. The old dead woods will find all means to pass the responsibilities on the design to others (usually private consultants). For the sake of money, there are many dare-devils professional engineers. The unlucky ones kanna like the nichole highway cave-in. But thousands got away signing blank cheques.

The government should start building more water catchment areas instead of casinos. They should really start thinking about the safety of Singaporeans and stop being too fixated towards improving the economy alone.

The MRT tunnel around ION is fully water-proofed and it is one of the contributing factors besides those mentioned earlier impeding water flow. It was built in the 80's and surely it is not the single impediment that caused the flood.

Exactly, that's why LKY's statement, no amount of engineering could prevent a flood does not hold water anymore.
His insatiable greed to have more land and water was hastily achieved with no regards for good engineering practice.

bro,
you think we'll be able to test the hypothesis today?

 

[moolightaffairs]

any news of flood?

 

[laksaboy]

The land which ION Orchard now stands on was once an open park, and on Sundays you could see Filipino maids relaxing and having a picnic. Occasionally, there would be open air music performances too.

any news of flood?

me reckoned the volume may be similar but perhaps not at the same rate. if the rain persists, and the skies opened up for a big one, the already water logged areas might show some signs. will check around Eunos, Still road area in a jiffy :o:o:o

bro,
great info there, i.e. to say, the tunnels leading to ION are newly constructed?

 

[zhihau]

a good time to test the hypothesis? :o:o:o
