• Modelling resilience in a water supply system : contrasting conditions of drought and flood 

  Goonetilleke, Ashantha (Kumamoto University, 2012)

  This paper presents an approach to modelling the resilience of a generic (potable) water supply system. The system is contextualized as a meta-system consisting of three subsystems to represent the natural catchment, the ...
• Building community resilience: learning from the 2011 floods in Southeast Queensland, Australia 

  Goonetilleke, Ashantha (Kumamoto University, 2012)

  The year 2010 was the wettest year on record for Queensland, Australia and the wettest year since 1974 for Southeast Queensland. The extremely heavy rain in early January 2011 fell on the catchments of heavily saturated ...
• Understanding treatment characteristics of constructed stormwater wetlands 

  Goonetilleke, Ashantha (RMIT Publishing, 2012)

  Constructed wetlands are a common structural treatment measure employed to remove stormwater pollutants and forms an important part of the Water Sensitive Urban Design (WSUD) treatment suite. In a constructed wetland, a ...
• WSUD application audit at gold coast city 

  Goonetilleke, Ashantha (Engineers Australia, 2012)

  In recent years, Water Sensitive Urban Design (WSUD) has been strongly promoted in South East Queensland to mitigate quantity and quality issues in relation to stormwater. Gold Coast City Council has implemented WSUD devices ...
• Application of Resilience concept for enhanced management of water supply systems 

  Goonetilleke, Ashantha (International Conference on Sustainable Built Environment (SBE), 2013)

  This paper presents an approach to developing indicators for expressing resilience of a generic water supply system. The system is contextualised as a meta-system consisting of three subsystems to represent the water ...
• Role of solids in heavy metals buildup on urban road surfaces 

  Goonetilleke, Ashantha (ASCE, 2011-09)

  Solids are widely identified as a carrier of harmful pollutants in stormwater runoff exerting a significant risk to receiving waters. This paper outlines the findings of an in-depth investigation on heavy metal adsorption ...
• Source characterisation of road dust based on chemical and mineralogical composition 

  Goonetilleke, Ashantha (Elsevier, 2012-04)

  Road dust contain potentially toxic pollutants originating from a range of anthropogenic sources common to urban land uses and soil inputs from surrounding areas. The research study analysed the mineralogy and morphology ...
• Prediction of the wash-off of traffic related semi- and non-volatile organic compounds from urban roads under climate change influenced rainfall characteristics 

  Goonetilleke, Ashantha (Elsevier, 2012-04)

  Traffic generated semi- and non-volatile organic compounds (SVOCs and NVOCs) pose a serious threat to human and ecosystem health when washed off into receiving water bodies by stormwater. Climate change influenced rainfall ...
• Inadequacy of land use and impervious area fraction for determining urban stormwater quality 

  Goonetilleke, Ashantha (Springer, 2012-03)

  Urban stormwater quality is multifaceted and the use of a limited number of factors to represent catchment characteristics may not be adequate to explain the complexity of water quality response to a rainfall event or ...
• Role of traffic in atmospheric accumulation of heavy metals and polycyclic aromatic hydrocarbons 

  Goonetilleke, Ashantha (Elsevier, 2012-07)

  Traffic related emissions have been recognised as one of the main sources of air pollutants. In the research study discussed in this paper, variability of atmospheric total suspended particulate matter (TSP), polycyclic ...
• Inherent errors in pollutant build-up estimation in considering urban land use as a lumped parameter 

  Goonetilleke, Ashantha (Wiley, 2012-09)

  Stormwater quality modeling results are subject to uncertainty. The variability of input parameters is an important source of overall model error. An in-depth understanding of the variability associated with input parameters ...
• Taxonomy for rainfall events based on pollutant wash-off potential in urban areas 

  Goonetilleke, Ashantha (Elsevier, 2012-10)
