Firstly, the importance of the urban water environment is highlighted and the major problems urban water bodies face and strategies to safeguard the water environment are explored. Secondly, the diversity of pollutants entering the water environment through stormwater runoff are discussed and modeling approaches for factoring in climate change and future urban and transport scenarios are proposed. Thirdly, by linking the concepts of sustainable urban ecosystems and sustainable urban and transport development, capabilities of two urban sustainability assessment models are demonstrated. To achieve sustainability of the urban water environment and future viability of treatment strategies, a framework that supports their adaptation to future challenges is required. A conceptual framework which involves a decision making cycle integrating best management practices and best planning practices that can be adopted to ensure future adaptation is also presented.

Taking a holistic approach and with practical applications for modeling and predictions, Sustainable Urban Water Environment will strongly appeal to postgraduate students, practitioners and researchers in environmental science, environmental policy and urban transport planning.

This book presents new findings on intrinsic variability in pollutant build-up and wash-off processes by identifying the characteristics of underlying process mechanisms, based on the behaviour of various-sized particles. The correlation between build-up and wash-off processes is clearly defined using heavy metal pollutants as a case study. The outcome of this study is an approach developed to quantitatively assess process uncertainty, which makes it possible to mathematically incorporate the characteristics of variability in build-up and wash-off processes into stormwater quality models. In addition, the approach can be used to quantify process uncertainty as an integral aspect of stormwater quality predictions using common uncertainty analysis techniques. The information produced using enhanced modelling tools will promote more informed decision-making, and thereby help to improve urban stormwater quality.

This book presents a detailed analysis in relation to human health risk assessment of the main toxic chemical pollutants in urban stormwater generated from urban traffic and land use activities. The knowledge presented in this book was derived based on comprehensive experimental investigations including field sampling, laboratory testing, mathematical modelling, spatial analysis and multivariate and univariate statistical data analyses.

The key highlights of the book include the quantitative assessment of the human health risk posed by key toxic chemical pollutants in urban stormwater and the development of linkages between risk and traffic and land use. Additionally, a suite of mathematical equations are presented to predict human health risk based on traffic and land use characteristics through mathematical modelling. These outcomes can significantly assist in effective stormwater risk management under changing traffic and land use in the urban environment. The knowledge presented is of particular interest to readers such as stormwater treatment design specialists, decision-makers and urban planners since these outcomes provide practical suggestions and recommendations for effective urban stormwater treatment design.
