Wetlands for Water Pollution Control, Second Edition, covers the fundamental science and engineering principles relevant to the drainage and treatment of both storm and wastewater. Standard and novel design recommendations for predominantly constructed wetlands and related sustainable drainage systems are also provided to account for the interests of professional engineers and environmental scientists. This revised edition deals with the design, operation, maintenance, and water quality monitoring of traditional and novel wetland systems, but also provides information on the analysis of asset performance and modeling of treatment processes, along with performances of existing infrastructures in predominantly developed, but also developing countries, and the sustainability and economic issues involved. This new edition contains 10 new chapters, along with multidisciplinary, experimental, and modeling-orientated case study topics that include natural wetlands, constructed treatment wetlands for pollution control, sustainable drainage systems, and specific applications, such as wetlands treating hydrocarbon and ammonia, as well as ecological sanitation systems recycling treated. Contains a broad overview of water and environmental engineering aspects relevant for the drainage and treatment of storm water and wastewater, respectively Includes standard and novel design, operation, monitoring and maintenance recommendations for predominantly constructed wetlands and related sustainable drainage systems Provides detailed solutions to pressing water quality challenges associated with constructed treatment wetlands, integrated constructed wetlands, sustainable flood retention basins, farm constructed wetlands and storm water ponds, and other sustainable biological filtration and treatment technologies linked to public health engineering

Wetland Systems to Control Urban Runoff integrates natural and constructed wetlands, and sustainable drainage techniques into traditional water and wastewater systems used to treat surface runoff and associated diffuse pollution. The first part of the text introduces the fundamentals of water quality management, and water and wastewater treatment. The remaining focus of the text is on reviewing treatment technologies, disinfection issues, sludge treatment and disposal options, and current case studies related to constructed wetlands applied for runoff and diffuse pollution treatment. Professionals and students will be interested in the detailed design, operation, management, process control and water quality monitoring and applied modeling issues. * Contains a comprehensive collection of timely, novel and innovative research case studies in the area of wetland systems applied for the treatment of urban runoff * Demonstrates to practitioners how natural and constructed wetland systems can be integrated into traditional wastewater systems, which are predominantly applied for the treatment of surface runoff and diffuse pollution * Assesses the design, operation, management and water treatment performance of sustainable urban drainage systems including constructed wetlands

Abstract: "A research program to investigate the viability of using urban freshwater wetlands for stormwater management and nonpoint pollution control. Resource Planning Section, King County Department of Planning and Community Development, WA., July 1, 1986. Washington State Department of Ecology, WDOE Project Number G0086039, 16 pages. A review of the literature revealed little information in the long-term effects of using freshwater wetlands for urban stormwater management and nonpoint pollution control. This is especially true for freshwater wetlands in the Pacific Northwest. King County began a study in 1986 to obtain sound scientific data for management decisions regarding freshwater wetlands. This Research Program is one of three products resulting from the first phase of that study. A research technical advisory committee was formed to help formulate a research design that will answer many of the long-term questions regarding the use of wetlands for urban surface water management. A series of research questions were formulated, and a research methodology prepared to answer those questions according to five subject areas: biology, sediments and soils, water quality, groundwater, and hydrology."

Urbanization affects wetlands in direct and indirect ways. Over the past several decades it has become increasingly apparent that unmanaged runoff is the primary threat to the country's watershed resources. Wetlands and Urbanization: Implications for the Future is the result of a ten year research project focused on the understanding and ma

Nonpoint stormwater runoff remains a leading threat to surface water quality in the U.S. Increased impervious surfaces, climate change, and increasing water demands put even more pressure on stormwater managers to improve stormwater management practices with regards to cost effectiveness, removal performance, and ecological sustainability. More effective BMPs can be designed by understanding the nature of pollutant runoff loads with respect to the hydrograph. Many studies have been performed on the first flush (FF) phenomenon (the assumption that the initial portion of a rainfall-runoff event is more polluted than the later portions). However, controversy remains on whether or not the first flush truly exists, which environmental factors influence a first flush, and how best to define the first flush phenomenon. The objective of this study as to evaluate the first flush occurrence in two small urban watersheds (differing in extent of impervious area) using multiple analytical methods and definitions previously published in the literature. The first watershed is 4.8 acres with 67% impervious roadway and the second watershed is 5.6 acres with 87% wooded land cover. Statistical tests were performed to analyze for site-specific correlations between first flush strength and rainfall characteristics (e.g. rainfall depth, peak flow rate, runoff volume, peak rainfall intensity, and antecedent dry period) and determine differences in FF strength between different land uses and pollutants. Furthermore, the FF study was utilized to perform an annual treatable load analysis in order to evaluate the effectiveness of two hypothetical BMPs sized to treat stormwater from the highly impervious watershed based on the 1.3 cm, 1.9 cm, 2.6 cm and 3.2 cm of rainfall water quality volumes. A year-long study captured stormwater samples from over 33 storm events and analyzed for TSS, turbidity, nutrients and heavy metals. Samples were collected using flow-based sampling frequencies that yie.

This book explains how with careful planning and design, the functions and performance of constructed wetlands can provide a huge range of benefits to humans and the environment. It documents the current designs and specifications for free water surface wetlands, horizontal and vertical subsurface flow wetlands, hybrid wetlands and bio retention basins; and explores how to plan, engineer, design and monitor these natural systems. Sections address resource management (landscape planning), technical issues (environmental engineering and botany), recreation and physical design (landscape architecture), and biological systems (ecology). Site and municipal scale strategies for flood management, storm-water treatment and green infrastructure are illustrated with case studies from the USA, Europe and China, which show how these principles have been put into practice. Written for upper level students and practitioners, this highly illustrated book provides designers with the tools they need to ensure constructed wetlands are sustainably created and well manage
