Urban Drainage has been thoroughly revised and updated to reflect changes in the practice and priorities of urban drainage. New and expanded coverage includes: sewer flooding the impact of climate change flooding models the move towards sustainability. Providing a descriptive overview of the issues involved as well as the engineering principles and analysis, it draws on real-world examples as well as models to support and demonstrate the key issues facing engineers dealing with drainage issues. It also deals with both the design of new drainage systems and the analysis and upgrading of existing infrastructure. A unique and essential textbook for students of water, environmental and public health engineering as well as a valuable resource for practising engineers.
