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...

20110920 SASC4 Case Study - Bukit Timah Canal  http://bettersingapore.blogspot.com/2011/09/20110920-sasc4-case-study-bukit-timah.html Bukit Timah Canal   is chosen not just because it has long flood history. It is chosen because  Serving heavier tropical rain forest storms Over more than 7km mid-stream The elevation is only 11 mete r Newton circle  16.334m (N1° 18´  47.05”  E103° 50´ 18.51”)  Bukit timah    27.24m  (N1° 29 ´24.27” E 103° 46´ 45.29”)   Data from   http://srtm.csi.cgiar.org/SELECTION/inputCoord.asp using Global Mapper  software If we can resolve Bukit Timah, we can resolve most flood problems domestically as well as contribute to others, internationally. A Precedence for others Waterway design is a matured field, there are always precedence to refer to, to help us from errors, wastage, stifling flow. 20110830 PUB is digging deeper drains from 3 to 5.7 meter for Zion-K...

20110920 SASC3 What Impede Flow - Over-sized Excessive Depth http://bettersingapore.blogspot.com/2011/09/20110920-sasc3-what-impede-flow-over.html What impede flow - over-sized drains dig excessively deep. Not only they cost a lot of money, material, labor and maintenance, they impede flow. Latest project on Alexandra River  will not mitigate flood, just from theory all experts use. First waterway design is a very matured field, not an art, not rocket sciences - just a lot of common sense with keen observation of rain, flow, terrain, soil.... Therefore we can have double confirmation from prior experience and real solutions, not models. The following two videos show how deeper drains, bigger drains is impeding flow when it is too deep that gradient is sacrificed. 2009 11 05 Hrs 1247 Rain With gradient, upstream rapid flow can counter right angle interruption.  Big, deep downstream drain that has almost zero gradient Simmer this rapid to almost stagnation, dead ...

20110920 SASC2 Singapore Unique Advantage http://bettersingapore.blogspot.com/2011/09/20110920-sasc2-singapore-unique.html Comparing with our immediate neighbor having similar rain fall intensity. On equal catchment size Singapore has many more rivers, higher gradient, straighter rivers, shorter distance to reach the ocean. We definitely can resolve flood problem. (note the scale is approximately the same on both maps) Our Higher Objectives are  1. Recover water economically and elegantly 2. Beautify our environment Two Keys to Singapore Water Resource We have not fully realize the economic advantages of being a small island. Therefore TWO key features of this island that is advantageous economicallyto waterway design. They have to be emphasized in writing, in publicly known writing. With these two advantages used, we can not only economically, expediently, elegantly resolve flood, we can also improve water quality and expand water stora...

Global Warming brings two new challenges to Water Policies, Waterway design and management: Heavier rainfall Algae A comprehensive approach to mitigate, resolve the above is presented as  Self Accelerated Self Cleansing (SASC) Waterway SASC has two main purposes: Accelerate water flow by reduces resistance and improve use of gravity, geometries Self Cleansing by: Intensify aeration to promote eco-operations, reduce algae formation. Effectively separate flotsam and silt from water a patenting invention Effective Seperation, Easy Maintenance H820 IPOS 200806192-1 that directs flotsam and silt to concentrate at locations - located away from flow path so that flow is not affected - first choke free filter ever invented (patent examination confirmed). - easy access - create massive health preserving jobs for longer life span work force. SASC is not an ideal, but a ready technology Provide clear direction for nations' water policy  Provide for both master plannin...
