Riassunto

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.
