Implementing Water Sensitive Urban Design Through Regulation

Implementation of water sensitive urban design to meet established stormwater quality objectives in Melbourne has until recently occurred through Melbourne Water drainage scheme requirements and funding programs to local government. Significant advances in the regulatory framework for new development to incorporate WSUD have been delivered through the Sustainable Neighbourhoods Clause 56 of the Victoria Planning Provisions. The successful implementation of Clause56 involves local government requiring incorporation of WSUD into residential subdivision development and for management of sites during construction.

Impact of Spatial Variability of Rainfall on Predicted Irrigation Demand: Case Study of Melbourne

Melbourne’s land cover is spatially variable and experiences a strong natural precipitation gradient from west to east. Using precipitation and potential evaporation data, along with land surface characteristics for ten sites across Melbourne, this study investigates spatial differences in evapotranspiration and irrigation demand. Using a water balance model for outdoor water use only, it was found that irrigation demand is largely dependent on the vegetated fraction (gardens and parks) of the sites.

Integral Water Management, Oriented To The Renovation And Urban - Architectonic Sustainable Planning, Of The El Palomar Development

The present work describes of general way to the Project of Integral Water Management, Oriented to theRenovation And Urban - Architectonic Sustainable Planning, of the El Palomar Development at Municipality of Tlajomulco de Zúñiga, Jalisco, Mexico. “El Palomar Development” is an area of high economic level in the Metropolitan Zone of Guadalajara and belongs to “La Primavera” Forest and it is at the upstream of the“El Ahogado” basin which is a sub-basin of the Lerma-Santiago River. This last basin is the most important in western of México.

Best Practice For Modelling Sustainable Urban Drainage System Structures--Kirkham

Sustainable Urban Drainage Systems (SUDS) design has traditionally been simplistic, using basic equations and “rules of thumb” often leading to conservative designs. Now with plenty of information available advising planners about the different types of SUDS structures available it is often left to engineers to build or develop hydraulic models to quantify how these structures will operate for a range of operating conditions. This paper will explore how SUDS design on a range of real life case studies compare using a detailed modelling approach against traditional approaches. The results show the benefits of modelling from a SUDS perspective, where traditionally little modelling has been undertaken.

Decentralized Rainwater Management – Part of decentralized environmentallysound water and sanitation systems

Decentralized rainwater management measures can be taken to develop and restore sustainability in rural and urban areas. Examples carried out in densely populated urban areas with water-impermeable soils showed that to decentralize rainwater management is possible. At present this type of decentralized management primarily contributes to a failure-free function of mixed sewer systems and wastewater treatment plants.

Drought Proofing Cities: Desalination vs rainwater Tanks – A Challenge To Water Supply Managers

Drought is affecting water supply in many cities across Australia. However, rainwater tanks do not appear to be considered a serious water supply option by many government agencies. The major concern about rainwater tanks for drought response is the yield they would provide during drought conditions. The results presented in his paper challenge the widely held assumption that rainwater tanks cannot provide a reliable supply during drought. Furthermore the real cost per kilolitre of desalination is challenged by investigating the assumption that once a desalination plant is built, it will be running constantly. However cost, climate change and energy management suggest that the desalination plant be used only when required.

Estimation of MUSIC Rainfall-Runoff Parameters for Urban Catchments in NSW

This paper outlines the results of continuous simulation rainfall-runoff modelling undertaken for 7 urban catchments within NSW and the ACT. The models weredeveloped to estimate appropriate MUSIC rainfallrunoff parameters for urban catchments in NSW. Parameter estimates were derived through a detailed calibration and verification process and yielded some important insights into the use of these parameters in MUSIC.

Experimental Study on Performance of Permeable Sidewalk Pavement Using Reused Construction Wastes

Nowadays the modern environment of city and country is composted by cement, asphalt, brick and mental with impermeable materials. Vehicle road, sidewalk (footpath, walkway, and pedestrian way), commonness park, amusement park, and plaza are usually changed as impermeable harden ground surface.

Field Testing The Effectiveness Of Pervious Pavements As A Water Sensitive Urban Design Initiative

Pervious pavements in car parks and driveways reduce peak discharge and the volume of runoff flowing in to urban drains and improve the water quality by trapping the sediments in the infiltrated water. This reduces the risk of pollutants such as suspended solids and particle bound chemicals such as phosphorous, nitrogen, heavy metals and oils and hydrocarbons entering receiving waters.

Hydrologic, Water Quality And Geomorphic Indicators Of Catchment Effective Imperviousness

Recent research has related waterway ecosystem health to a simple indicate of catchment Effective Imperviousness. Effective Imperviousness(EI) is defined as impervious area that is directly connected, via a stormwater pipes or channels, to receiving waters. Thissimple relationship between catchment EI and waterway ecosystem health cannot be directly translated into stormwater management objectives without first identifying key characteristics representing catchment Effective Imperviousness.
