This new book presents powerful techniques that can be used to address issues and problems related to wetlands and surface waters. It is the first book of its kind to address inventory and management of wetlands and water quality problems using GIS and remote sensing technologies. Wetland and Environmental Applications of GIS describes a variety of techniques, applications, and case studies for evaluating wetland and surface water characteristics at the landscape scale. The book details wetland and environmentally-oriented surface water resource studies using spatial and spectral based technologies such as GIS, remote sensing, computer modeling, and image display. Introductory material is included in the first section to provide a common background and to refresh or introduce concepts to the professional. The second section details applications of these technologies in studies of wetlands, including the use of GIS and archival satellite data in evaluating and measuring sediment types, water depth, and environmental change in the coastal wetlands of the Great Lakes. The third section addresses various environmental applications of GIS, such as locating non-point pollution sources and managing oil spills. The final section supplies additional information and applications, with particular emphasis on potential contributions of remote sensing.

This work advises owners and managers how woodlands and forests influence the freshwater ecosystem, and gives guidance on how operations should be carried out in order to protect and enhance the water environment. The guidelines apply equally to forest enterprises and the private sector.

Of all the outputs of forests, water may be the most important. Streamflow from forests provides two-thirds of the nation's clean water supply. Removing forest cover accelerates the rate that precipitation becomes streamflow; therefore, in some areas, cutting trees causes a temporary increase in the volume of water flowing downstream. This effect has spurred political pressure to cut trees to increase water supply, especially in western states where population is rising. However, cutting trees for water gains is not sustainable: increases in flow rate and volume are typically short-lived, and the practice can ultimately degrade water quality and increase vulnerability to flooding. Forest hydrology, the study of how water flows through forests, can help illuminate the connections between forests and water, but it must advance if it is to deal with today's complexities, including climate change, wildfires, and changing patterns of development and ownership. This book identifies actions that scientists, forest and water managers, and citizens can take to help sustain water resources from forests.

Large-Scale Ecosystem Restoration presents case studies of five of the most noteworthy large-scale restoration projects in the United States: Chesapeake Bay, the Everglades, California Bay Delta, the Platte River Basin, and the Upper Mississippi River System. These projects embody current efforts to address ecosystem restoration in an integrative and dynamic manner, at large spatial scale, involving whole (or even multiple) watersheds, and with complex stakeholder and public roles. Representing a variety of geographic regions and project structures, the cases shed light on the central controversies that have marked each project, outlining • the history of the project • the environmental challenges that generated it • the difficulties of approaching the project on an ecosystem-wide basis • techniques for conflict resolution and consensus building • the ongoing role of science in decision making • the means of dealing with uncertainties A concluding chapter offers a guide to assessing the progress of largescale restoration projects. Large-Scale Ecosystem Restoration examines some of the most difficult and important issues involved in restoring and protecting natural systems. It is a landmark publication for scientists, policymakers, and anyone working to protect or restore landscapes or watersheds.
