Water resources engineering entails the assessment, development and management of water resources - such as rivers, lakes, reservoirs, groundwater, estuaries and coastal waters - for the benefit of mankind. Design of water resources systems presents a comprehensive coverage of the the design fundamentals of key elements of water resources engineering infrastructure. Through coverage of the basic principles and by using fully-worked examples illustration the application of the basic theory, design of water resources systems follows a typical engineered water cycle for the provision of wholesome drinking water to an urban environment and the collection, treatment and disposal of the municipal wastewater generated. This book will be invaluable to civil and environmental engineers, students in related disciplines, and as a reference work for design engineers and water industry technical personnel.
