The merger of two successful events to form the 30th International Conference on Modelling, Monitoring and Management of Air and Water Pollution provided the papers that are published in this volume. Many important air pollution issues are discussed, demonstrating the widespread nature of the air pollution phenomena and the in-depth exploration required to address their impacts on human health and the environment. In addition, the topic of Water Pollution is discussed in a number of contexts across different areas of water contamination. The environmental problems caused by the increase of pollutant loads discharged into natural water bodies requires the formation of a framework for regulation and control. This framework needs to be based on scientific results that relate pollutant discharge with changes in water quality. The results of these studies allow the industry to apply more efficient methods of controlling and treating waste loads, and water authorities to enforce appropriate regulations regarding this matter. Environmental problems are essentially interdisciplinary. Engineers and scientists working in this field must be familiar with a wide range of issues including the physical processes of mixing and dilution, chemical and biological processes, mathematical modelling, data acquisition and measurement, to name but a few. In view of the scarcity of available data, it is important that experiences are shared on an international basis. Thus, a continuous exchange of information between scientists from different countries is essential.

Research works were presented at the 8th International Conference on Flood and Urban Water Management with the aim of developing innovative solutions that can help bring about multiple benefits toward achieving integrated flood risk and urban water management strategies and policy. The papers resulting from these works form this book. Flooding is a global phenomenon that claims numerous lives worldwide each year. When flooding occurs in urban areas, it can cause substantial damage to property as well as threatening human life. In addition, many more people must endure the homelessness, upset and disruption that are left in the wake of floods. The increased frequency of flooding in the last few years, coupled with climate change predictions and urban development, suggest that these impacts are set to worsen in the future. How we respond and importantly, adapt to these challenges is key to developing our long term resilience at the property, community and city scale. As our cities continue to expand, their urban infrastructures need to be re-evaluated and adapted to new requirements related to the increase in population and the growing areas under urbanization. We also need to consider more nature-based interventions to the management of flood risk, including the adoption of more catchment-based approaches. These are now being recognised as being more sustainable and also able to achieve wider benefits to the environment and society as a whole. Water supply systems and urban drainage are also increasingly important due to this expansion. Topics such as contamination and pollution discharges in urban water bodies, as well as the monitoring of water recycling systems are currently receiving a great deal of attention from researchers and professional engineers working in the water industry. Mitigating losses from water distribution networks and effective, efficient and energy-saving management are key goals for optimising performance and reducing negative impacts. Sewer systems are under constant pressure due to growing urbanization and climate change, and the environmental impact caused by urban drainage overflows is related to both water quantity and water quality. This book is aimed at researchers, academics and practitioners involved in research and development activities across a wide range of technical and management topics related to urban water and flooding and its impacts on communities, property and people.
