  11. Technical Knowledge • What technical knowledge? • Simplify the problem • Break it down • Solve individually • Combined them http://www.msmam.com

  12. Design Storm Calculate IDF data Hydrograph Method Time Area Method or Runoff Routing Method Reservoir Routing Level Pool Routing Through Detention Storage I t Qp Detention Basin Calculate Water Level (Workshop 2) Use HEC-RAS model to calculate water level in drain Open Drain t http://www.msmam.com

  13. Technical Knowledge • What technical knowledge? • Simplify the problem- models • Break it down- 4 models • Solve individually- 4 procedures • Combined them- outflow hydrograph http://www.msmam.com

  14. Technical Knowledge • Tip: You can refer to the relevant parts of the Manual http://www.msmam.com

  15. Conclusion • You will reach your destination safely if you have the right skill and tool. http://www.msmam.com

  16. Tricks & Shortcuts • Question: What is the most powerful tool you need to apply MSMA? http://www.msmam.com

  17. Requirements • Cheap • Save time • Automation • Repetitive • Accurate • Reporting http://www.msmam.com

  18. Spreadsheet http://www.msmam.com

  19. Why Spreadsheets? • Spreadsheets are powerful! • Cheap- free • Save time- recycle • Automation- computation is automatic • Repetitive- iterative work • Accurate- less computation error • Reporting- graphs & tables http://www.msmam.com

  20. Why Spreadsheets? • Good for repetitive calculation • Good for presentation • Can be applied from job to job • Easy for checking & record • Lifetime tool of an engineer http://www.msmam.com

  21. Spreadsheet vs Proprietary Software • You understand what you do using spreadsheet (hand calc) • You know how and where the parameters are used • Debugging easier- you know what parameters to change http://www.msmam.com

  22. Conclusion: • Spreadsheet will make work smarter and not harder. • More importantly it will make you a better engineer. http://www.msmam.com

  23. Create your own physical library of tools, resources & software • Create your own physicallibrary of tools, resources & software recommended in MSMA • Print out all manuals- bind them • Read them. • How I do it? http://www.msmam.com

  24. This is my Resources on MSMA: http://www.msmam.com

  25. Part of the physical libraryin my office: http://www.msmam.com

  26. Create your own digital library of tools, resources & software • Create your own digitallibrary of tools, resources & software recommended in MSMA • Save into a PC/notebook computer • Learn to apply them. • How I do it? http://www.msmam.com

  27. PC- digital library: http://www.msmam.com

  28. Create spreadsheets for all MSMA computation • Create spreadsheets for all MSMA computation • Save them and use them for future jobs • Refine them • Improve them • Keep it in your notebook PC • They ARE your money-making tools!!! http://www.msmam.com

  29. Why Spreadsheets? • Spreadsheets are powerful! • Good for repetitive calculation • Can plot graph easily • Ideal for output to report • Can be applied from job to job • Example: culverts spreadsheet http://www.msmam.com

  30. Examples of Spreadsheets: • Design storm (IFD computation) • Peak discharge computation (Rational Method, Time-Area Method) • Reservoir routing (Level Pool Routing) • Culvert design procedure (inlet & outlet control) • Plus many more…(continue next page) http://www.msmam.com

(more added from time to time) http://www.msmam.com

  32. Download Software Recommended in MSMA • Download software recommended in MSMA • Install them • Print out user manual >>> physical library • Read them • Go through worked example http://www.msmam.com

  33. Examples of Software Recommended in MSMA • Many software- proprietary & public domain • MUST HAVE software: • Hydrologic Modelling • Runoff-Routing Computer Models (HEC-HMS) • Hydraulic Modelling • HEC-RAS http://www.msmam.com

  34. Build Your Own Library of Tools • MSMA recommends many free software & resources. • Save $1,000 compared to commercial software. • Download, install, print manual & learn to apply them. • Your money-making tools! http://www.msmam.com

  35. Download Software Not Recommended in MSMA • This is OPTIONAL! • Download software not recommended in MSMA • Install them • Print out user manual >>> physical library • Read them • Examples: some water quality model http://www.msmam.com

  36. Where to Find Good Software • US Army Corps of Engineers- Hydrologic Engineer Center • US EPA • US Geological Survey • Etc… http://www.msmam.com

  38. Part A- What is MSMA? • What is the purpose of MSMA? • What are major differences between MSMA & PDP1? • Why the need for MSMA? http://www.msmam.com

  39. Tip 1- What is the purpose of MSMA? • New urban drainage design procedures and guidelines for Malaysia… • “Urban Stormwater Management Manual for Malaysia” • “Manual Saliran Mesra Alam Malaysia” or MSMA • Published by DID in 2000 • Gazetted by the Federal Government in 2001 http://www.msmam.com

  40. Tip 2- Major Differences Between MSMA & PDP1? • MSMA • >1,100 pages • 20 volumes • 48 chapters • 2 three-inch arch folders http://www.msmam.com

  41. Compared to the Old Procedure… • PDP1- Planning and Design Procedure No. 1 published by D.I.D. in 1975. • 242 pages • 10 chapters • ½ inch thick http://www.msmam.com

  42. Tip 3- Why MSMA? • Why there is a need to introduce MSMA? http://www.msmam.com

  43. The Star- KL Hit By Floods! http://www.msmam.com

  44. KL- A Floating City? http://www.msmam.com

  45. LRT Becomes LBT? http://www.msmam.com

  46. The Only Free Parking Lot in KL http://www.msmam.com

  47. Part B- What’s new in MSMA? • What are major changes in MSMA? • Rapid Disposal Vs Control-at-Source • Major & minor system concept • Onsite Detention, Community and Regional Detention/Retention http://www.msmam.com

  48. Tip 4- Some Major Changes: • Major changes in design approach & procedures • Emphasis on water quantity and quality management in MSMA. • More comprehensive coverage of subject matters • Emphasis on computational methods • MSMA- SI units, PDP1- Imperial units http://www.msmam.com

  49. Tip 5- Rapid Disposal Vs Control-at-Source • PDP1- Rapid Disposal • MSMA- Control-at-Source http://www.msmam.com

  50. Old Approach- Rapid-Disposal (Conveyance Oriented Approach) Large and deep Source of pollution W/o erosion and sediment control http://www.msmam.com
