Wetland Systems covers broad water and environmental engineering aspects relevant to the drainage and treatment of storm water and wastewater, providing a descriptive overview of complex 'black box' treatment systems and general design issues involved. Standard and novel design recommendations for predominantly constructed wetlands and related sustainable drainage systems are provided to match the interests of professional engineers and environmental scientists. Wetland Systems deals comprehensively not only with the design, operation, maintenance and water quality monitoring of traditional and novel wetland systems, but also with the analysis of asset performance, and modelling of treatment processes and performances of existing infrastructure. Although it focuses predominantly on developed countries, it also discusses developing countries, and the sustainability and economic issues involved.Solutions to pressing water quality problems associated with constructed treatment wetlands, integrated constructed wetlands, farm constructed wetlands and storm water ponds, and other sustainable biological filtration and treatment technologies linked to public health engineering are explained. Case study topics are diverse: wetlands including natural wetlands and constructed treatment wetlands; sustainable water management, including sustainable drainage systems; and specific applications, such as wetlands treating hydrocarbon. The research projects covered are multi-disciplinary, holistic, experimental and modelling-orientated.
