     Suggestions

     Conclusion

  • INSPIRING CREATIVE & INNOVATIVE MINDS

    Background

    Natural Disaster: A Lesson For Future

    Development Planning

    • Development patterns greatly impact the

    existence & function of natural systems;

    e.g. rivers

    • Destruction can pose risks to life and

    property & greatly increase the cost of

    development

    • Johor flooding (Dec 2006 & Jan 2007)

    • public facility damages: RM 1.5 billion

    • Iskandar Malaysia - downfall: 350mm

    (2006); 400mm (2007)

    • Very important to understand the

    interrelationship of urbanization and

    natural, economic and cultural resources

    • Many agencies are now very concerned on

    how to deal with stormwater in a manner

    which is healthier, safer, and more in

    balance with the natural environment

  • INSPIRING CREATIVE & INNOVATIVE MINDS

    Background

    Stormwater Asset Inventory

     Part of (core component) JPS’s ‘Detailed

    Design of Stormwater Management

    Facilities’ projects:

    - Senai; Kulai; Pandan; Tmn Anggerik;

    Buntan; Rinting

     Mainly to tackle flash floods

     A similar development for ‘Flood Mitigation

    Master Plan Study For WPI’ (Iskandar

    Malaysia):

    - Sg Skudai, Sg Pulai, Sg Pendas, Sg

    Melayu, Sg Masai, Sg Kim Kim, Sg Kong

    Kong

     To develop using GIS

     To conform/ comply with MS 1759 : 2004

     Assets: - Waterways: rivers/ drains

    - Structures: bridges; culverts; weirs; tidal

    gauge; barrage; garbage traps; drop

    structures; outfalls; sewage treatment plants

    • Material

    • Geometry Type

    • Size

  • INSPIRING CREATIVE & INNOVATIVE MINDS

    Stormwater Assets

    Outfall  Feature: Shoreline Structure

     A structure extending into a body of water for

    the purpose of discharging sewage, storm

    runoff, or cooling water

     Associated Attributes:

    • Source (e.g. residential; industrial;

    oxidation pond)

  • INSPIRING CREATIVE & INNOVATIVE MINDS

    Stormwater Assets

    Weir  Feature: River Structure

     A barrier constructed to control the flow or

    raise the level of water

    Pond  Feature: Inland Water

     An open body of water smaller than a lake

    which is either naturally formed or man

    made

     Associated Attributes:

    • Type (e.g. detention; wastewater/

    oxidation)

  • INSPIRING CREATIVE & INNOVATIVE MINDS

    Stormwater Assets

    Sewage Treatment Plant  Feature: Sewerage

     Site that contains facilities for treating

    sewage

     May introduce outfall into river

     Associated Attributes:

    • Type (e.g. communal septic tank;

    oxidation pond)

  • INSPIRING CREATIVE & INNOVATIVE MINDS

    Stormwater Assets

    Trap Boom (Garbage Trap)  Feature: River Structure

    MS 1759: 2004

    MS 1759

    • Provides specification: data producers and

    users may exchange digital spatial data

    • Minimize duplication of effort in database

    development

    • Describes encoding of real world: in terms

    of features and attributes
