An understanding of environmental gradients is a prerequisite to the delineation of wetland boundaries, and buffers are a key element of wetlands conservation. This text focuses on current research and techniques for delineation in wetlands.

An understanding of environmental gradients (physical, chemical, hydrological, and biological) is a prerequisite to the accurate delineation of wetland boundaries. Presenting the wide-ranging views of academicians, environmentalists, policy makers, consultants, planners, engineers, hydrologists, biologists, geochemists, ecologists, and conservationists, Wetlands: Environmental Gradients, Boundaries, and Buffers focuses on current topics and research related to wetland delineation; summarizes the main issues of concern; and provides recommendations on research needs. In addition to...

Constructed wetlands are proving to be the best natural treatment syst em for landfill leachates. Most of the contaminants in landfill leach ates are degraded in treatment wetlands. Potential for long-term susta inability and significant cost savings are attractive features of this eco-technology. Documentation of the experience in this use of const ructed wetlands has been limited. Constructed Wetlands for the Treatme nt of Landfill Leachates is the first compilation of the results of re search from North America and Europe. Originally presented at an inter national symposium, this...
