Both practical and theoretical, this book provides the basic principles of soil chemistry, hydrology, wetland ecology, microbiology, vegetation and wildlife as a sound introduction to this innovative technology to treat toxic wastewaters and sludges. The use of wetlands for acid mine drainage, and metals removal in municipal, urban runoff, and industrial systems is discussed. Case histories are also presented, demonstrating specific types of constructed wetlands and applications to municipal wastewater, home sites, coal and non-coal mining, coal-fired electric power plants, chemical and pulp industry, agriculture, landfill leachate, and urban stormwater. Construction and management guidelines are clearly explained, providing information on applicable policies and regulations, siting and construction, and operations and monitoring of constructed wetlands treatment systems. Recent theoretical and empirical results from operating systems and research facilities, including such new applications as nutrient removal from eutrophic lakes and urban stormwater treatment within highway rights-of-way, are included. This book is an ideal resource for wastewater treatment plants, consulting engineers, federal and state regulators, industrial environmental managers, municipalities, environmental health professionals, and ecologists.

Design options and planning procedures must be critically examined to ensure that landscapes are created with sensitivity to water quality and management issues as well as overall ecological integrity. Handbook of Water Sensitive Planning and Design presents the history of water as a design and planning element in landscape architecture and describes new interpretations of water management. This text pushes the frontiers of standard water management in new directions, challenging readers into abandoning the comfortable safety of conducting business-as-usual within narrow disciplinary confines, and instead directing views outward to the exciting and incompletely mapped regions of true interdisciplinary water sensitive planning and design. With contributions from renowned practitioners, Part I provides seventeen chapters addressing the subject of site-specific water sensitive design and Part II presents another seventeen chapters focusing on issues relating to the water sensitive planning of riparian buffers and watersheds. In addition, Professor France has provided a "Response" to accompany each chapter, which succinctly underscores the salient features in more detail and emphasizes cross-linking to other chapters in the book. The "Overview" provides a brief road-map to navigate through the section. Finally, the discussion summaries at the end of each section elaborate on past problems, current challenges, and future directions. Handbook of Water Sensitive Planning and Design puts forward the very best of modern water sensitive planning and design and should be required reading for everyone involved in this dynamic and crucial field.

Coastal wetlands are under a great deal of pressure from the dual forces of rising sea level and the intervention of human populations both along the estuary and in the river catchment. Direct impacts include the destruction or degradation of wetlands from land reclamation and infrastructures. Indirect impacts derive from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. As sea level rises, coastal wetlands in most areas of the world migrate landward to occupy former uplands. The competition of these lands from human development is intensifying, making the landward migration impossible in many cases. This book provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide, and suggestions for their management. In this book a CD is included containing color figures of wetlands and estuaries in different parts of the world. - Includes a CD containing color figures of wetlands and estuaries in different parts of the world.

"Wetlands" has become a hot word in the current environmental debate. But what does it signify? In 1991, proposed changes in the legal definities of wetlands stirred controversy and focused attention on the scientific and economic aspects of their management. This volume explores how to define wetlands. The committee--whose members were drawn from academia, government, business, and the environmental community--builds a rational, scientific basis for delineating wetlands in the landscape and offers recommendations for further action. Wetlands also discusses the diverse hydrological and ecological functions of wetlands, and makes recommendations concerning so-called controversial areas such as permafrost wetlands, riparian ecosystems, irregularly flooded sites, and agricultural wetlands. It presents criteria for identifying wetlands and explores the problems of applying those criteria when there are seasonal changes in water levels. This comprehensive and practical volume will be of interest to environmental scientists and advocates, hydrologists, policymakers, regulators, faculty, researchers, and students of environmental studies.

Wetlands have been used for uncontrolled wastewater disposal for centuries. However, the change in attitude towards wetlands during the 1950s and 1960s caused the minimization of the use of natural wetlands for wastewater treatment (at least in developed countries). Constructed wetlands have been used for wastewater treatment for about forty years. Constructed wetland treatment systems are engineered systems that have been designed and constructed to utilize the natural processes for removal of pollutants. They are designed to take advantage of many of the same processes that occur in natural wetlands, but do so within a more controlled environment. The aim of this book is to summarize the knowledge on horizontal s- surface flow constructed wetlands (HF CWs) and objectively evaluate their treatment efficiency under various conditions. The information on this type of wastewater treatment technology is scattered in many publications but a comprehensive summary based on world-wide experience has been lacking. The book provides an extensive overview of this treatment technology around the world, including examples from more than 50 countries and examples of various types of wastewater treated in HF CWs.

Wetlands combine the beauty of both aesthetic form and ecological function in a way that few other landforms can match.

A Guide to Wetland Functional Design provides coherent design guidance on wetland replacement for estuarine, palustrine, riverine, and lacustrine systems. It describes wetland design from a functional standpoint and addresses subjects such as wetland hydrology, nutrient removal and transformation, sediment and toxicant retention, shoreline stabilization, floodflow alteration, groundwater recharge, and wildlife habitat. The guide is loaded with figures and tables to help illustrate key points, and it is presented in an easy-to-use format that leaves plenty of room for making notes. A Guide to Wetland Functional Design is an essential tool for individuals involved in a wetland replacement project. Environmental consultants, government regulators, environmental managers, and anyone interested in wetland functional design, wetland creation, or restoration will find this handy guide packed with useful information.
