7. 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

8. 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

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

10. 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

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

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

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

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

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

16. 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

17. 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

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

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

20. New Approach- Control-at-source Detention Pond Storage Tank Engineered Waterway Sediment Fence Gross Pollutant Trap Swale http://www.msmam.com

21. Tip 6- Major & Minor Systems Design Concepts http://www.msmam.com

22. Tip 7- Detention/Retention Storages Classification: OSD, Community & Regional http://www.msmam.com

23. Tip 8- Concept for Multilevel Stormwater System http://www.msmam.com

24. Tip 9- Examples of On-site Detention Facilities http://www.msmam.com

25. Tip 10- Devices for Community & Regional Detentions • Involves detention Storage • Example: detention basins/ponds • Attenuation of hydrograph • Pre and post-development peak discharge • Reduction in peak discharge because of detention control of runoff http://www.msmam.com

26. Tip 11- Differences Between OSD & Community Detention: • MSMA (Control-at-source): • On-site Stormwater Detention (OSD)- Minor Storm (10 year ARI) • Community or regional detention- Minor & Major Storms (20, 50, 100 year ARI) Many water quantity control measures eg, retention, detention and infiltration. Aim: To limit the post-development peak outflow rate to that existed before development Design ARI: Table 4.1. http://www.msmam.com

27. More Differences… • On-site Stormwater Detention (OSD)- individual housing/industrial lots. • Community/Regional facilities- catchment consists of mixed landuse/different owners. http://www.msmam.com

28. Part C- How to Master MSMA? • How to learn MSMA? • How to increase your productivity in applying MSMA? http://www.msmam.com

29. Read the MSMA Manual Question: But where to start? Answer: Start from Page 1… Tip 12- How to Learn to Apply MSMA? http://www.msmam.com

30. So You Started Reading MSMA… • Assuming you started reading from Page 1. • At Page 123, you’re bored. • At Page 456, you’re confused. • At Page 789, you finally give up! http://www.msmam.com

31. Too thick (>1,100 pages)! No time! Too complicated! Too much information! What is important? What is not important? You cannot relate what you read to your work Why Do You Fail? http://www.msmam.com

32. Tip 13- The Correct Way of Learning MSMA… • Understand what you need to know? • Read only what you need to know. • Do the worked examples. • Repeat the above. • Note: • Focal point- scatted information in MSMA, Eg detention basin design, reservoir routing, design ARI. • Allows you to relate what you read to your work & experience • Build upon what you already knew. You are not starting 100% new. http://www.msmam.com

33. So Why Do You Fail Again? • No focal point- reading disorganised information from Page 1 to 1,100. • Cannot relate to your work or what you already know. • You are bored! • That’s why you failed! http://www.msmam.com

34. Tip 14- Secrets for Success… • Understand what you need to know? • Focus only on what you need to know. • Do the worked examples. • Repeat the above. http://www.msmam.com

35. Tip 15- So You Want Some Tips? • Use Examples (Design Storm, Rational Method, Hydrograph Method, Reservoir Routing etc) as a starting point. • Read the relevant chapters in MSMA. • Go through the Worked Examples. http://www.msmam.com

36. Tip 16- 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

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

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

39. Tip 17- 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

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

41. Tip 18- 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

42. 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

43. Tip 19- 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

45. Tip 20- 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

46. Tip 21- 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

47. Tip 22- 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

48. Tip 23- 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
