Our flood is due to downstreams ponding, not due to 1. Immense water cathment upstreams, like Kuala Lumpur (Conventive Effect from Immense cathment Upstreams) , better 2. No intensification by Orograhpic effect in Thailand (Orographic effect from immense cloud up North blocked by Northern mountains tapering off Mount Everest) PUB using the right word, "Ponding." Ponding means water stayed stagnated as a pond, not flowing. Therefore the solution is quite clearly implied, we must make the water flow, we must therefore break this stagnation. There are two level of "Ponding" Micro-scopic - Choked filter, drains. When there a...

PUB releases latest findings on Orchard flash floods http://news.asiaone.com/News/Latest%2BNews/Singapore/Story/A1Story20111230-319062.html AsiaOne Friday, Dec 30, 2011 Findings from investigations of Orchard flash floods show that water could not flow out into Stamford Canal as it was full, said national water agency PUB in a statement today. Rainwater that drained off from the roof and the back area of Liat Towers overflowed into the basement area from an internal drain as water could not flow out into the canal when it was full. These were among the findings by PUB with regard to flash floods in the Orchard area on Dec 23, resulting in ankle-deep water in the basement shops of Liat Towers and Lucky Plaza. RELATED STORIES Countermeasures fail to stop flooding at Liat Towers Flash floods hit Liat Towers and other parts of Orchard Road PUB said that the pumping system at Liat Towers was able to pump out the water from the open basement area when the canal is not full.

20111027 Shenton Way Flood - Its Deeper Implications http://bettersingapore.blogspot.com/2011/10/20111027-shenton-way-flood-its-deeper.html Two Points and Three Wisdom from Founders' Drainage Design Codes Point One Photographer reported at the Asia Sq , one side of the rd the water was flooding fast but the opposite side across the road the water subsided very fast also This shows that one of the drains is totally choked. Our floods subside very fast, even before rain stop. One logical explanation is the high water pressure, caused by flood, push away obsticles in the drains, silts, leaves, rubbish. Our water way therefore has enough capacity. Our water way is too complex, costly to monitor, cleanse. Point 2 Massive floods comes only after ABC Projects swing into place . A $2 Billion dollars over the last decades did not include recent investment in  massive ABC projects, Bishan, Dawson, etc. http://bettersingapore.blogspot.com/2011/10/20101018-pu...

20111007 Expert Panel S'pore Drains cannt cope with more rainfall http://bettersingapore.blogspot.com/2011/10/20111007-expert-panel-spore-drains.html Expert panel: S'pore drains can't cope with more rainfall By Reico Wong my paper Friday, Oct 07, 2011 The current design and network system of canals and drains in Singapore are no longer adequate to handle the higher rainfall levels here, said the Expert Panel on Enhancing Flood Protection yesterday. So, more "robust" ways are needed to slow down the flow of storm water and increase its drainage , said the panel's chairman, Professor Chan Eng Soon. Possible ways include building porous roads to soak up storm water and adding greenery at the top of buildings to help capture and retain rain . Singapore's drainage infrastructure could also be enhanced, such that rainwater in a particular area is drained out through a network of canals, instead of just one , Prof Chan said. He revealed that t...

20101018 PUB $2 Billion Waterway http://bettersingapore.blogspot.com/2011/10/20101018-pub-2-billion-waterway.html Long-term planning cut flood-prone areas in Singapore http://wildsingaporenews.blogspot.com/2010/10/long-term-planning-cut-flood-prone.html PUB veteran helped design drainage system that has reduced such areas by 98%
Chang Ai-Lien, Straits Times 18 Oct 10;

PUB veteran Yap Kheng Guan knows Singapore's extensive network of drains like the back of his hand - after all, he built many of them.

Drains have been his passion in his 35-year career at the Environment Ministry and the national water agency PUB, which is responsible for drainage issues.

He has stood beside floodwaters as pig and water buffalo carcasses floated past in the 1970s. He has blasted through granite to build underground drainage tunnels.

But the seeds of his career in drainage were planted much earlier.

His secondary school, St Andrew's near Potong Pasir Village, was built on elevated g...

20110926 Waterway Costly Solutions Update http://bettersingapore.blogspot.com/2011/09/20110926-waterway-costly-solutions.html Ineffective design becomes not functioning at all. 20110506b Billions Dollars Experts Designed Coffee Bag http://bettersingapore.blogspot.com/2011/05/20110506b-billions-dollars-experts.html As registered in the above blog, this coffee bag is now no longer needed, and in the process of being demolished on 2011 07 12. Solvere agree with this action, because now Singapore river is a water storage, we no longer need such deep sump to store rain water, to buffer flood. This is how with good design, we use less land for waterway, yet we have better water management. This must be progressively done around the island, but  the ability to absorb the storm water must be computed and managed well. the filtration of flotsam and silt cannot be compromised. 20110506c How Singaporeans' Invention become Foreign Experts Contribu...
