Strategy SnapShotTotal Watermark Ã¢Â€Â“ City as a Catchment is our planÃ‚Â for integrated water cycle management for the next four years. Our vision is a healthy city in a healthy catchment. Seeing our city as a catchment means that we recognise the important roles of the natural and man-made catchments, including roads, roofs and impermeable surfaces. We want the whole of MelbourneÃ¢Â€Â™s community Ã¢Â€Â“ residents, workers and businesses alike, to think about water and its role inÃ‚Â our future, to help create a healthy city in aÃ‚Â healthyÃ‚Â catchment.The water security pressures caused by MelbourneÃ¢Â€Â™s recent 13-year drought have fundamentally changed the way we use water Ã¢Â€Â“ in our homes, offices and public open spaces, for recreation and for commercial and industrial purposes. City of Melbourne practices integrated water cycle management. this is the coordinated management of all components of the water cycle including water consumption, rainwater, stormwater, wastewater and groundwater, to secure a range of benefits for the wider catchment. This strategy is part of City of MelbourneÃ¢Â€Â™s work to become one of the worldÃ¢Â€Â™s most sustainable cities. We know that a successful future depends on understanding the risks that climate change poses, reducing our impact and becoming more resilient.As part of this, our goal is for Melbourne to be carbonÃ‚Â neutral by 2020, as outlined in our Zero Net Emissions by 2020 Ã¢Â€Â“ 2014 update. Other key strategies referenced in Total Watermark Ã¢Â€Â“ City as a Catchment include our: Climate Change Adaptation Strategy, Urban Forest Strategy, Open Space Strategy, Urban Ecology and Biodiversity Strategy and the Municipal Strategic Statement.

There are many models have been developed to estimate pollution from mobile sources. However, the sufficient data related to support an actual mobile emission, emission factor and traffic condition is hardly available. The paper describes a method to simplify the estimation of mobile source emission in the area. The simplification method is used to estimate emission factor using the data of idle vehicle emission test and to combine the data of vehicle fleet, traffic condition and road network to estimate daily vehicle density. To compute the mobile source emission, the area was divided into grids based on the sub-district administrative boundaries. The result indicates that the model is the appropriate available approach to estimate the mobile emission to emulate the data of idle vehicle emission test as emission factor. Further emission estimation using dynamic mode and the modified local driving condition are vitally important to improve the results of emission estimation as well as actual condition.
