This volume contains selected papers presented at both the 3rd International Conference on the Design, Construction, Maintenance, Monitoring and Control of Urban Water Systems and the 5th International Conference on Flood Risk Management and Response, organized by the Wessex Institute. These papers deal with three main subjects: water supply systems, urban drainage and flooding.Water distribution networks around the world often suffer substantial losses, which indicate energy and treatment waste. Sewer systems are under relentless pressure due to urbanisation and climate change, and the environmental impact caused by urban drainage overflows relates to both water quantity and water quality.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. Researchers, academics and practitioners actively involved in improving our understanding of flood events and our approaches to response, recovery and resilience will also find this book a valuable resource.
