Water quality and management are of great significance globally, as the demand for clean, potable water far exceeds the availability. Water science research brings together the natural and applied sciences, engineering, chemistry, law and policy, and economics, and the Treatise on Water Science seeks to unite these areas through contributions from a global team of author-experts. The 4-volume set examines topics in depth, with an emphasis on innovative research and technologies for those working in applied areas. Published in partnership with and endorsed by the International Water Association (IWA), demonstrating the authority of the content Editor-in-Chief Peter Wilderer, a Stockholm Water Prize recipient, has assembled a world-class team of volume editors and contributing authors Topics related to water resource management, water quality and supply, and handling of wastewater are treated in depth

The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Manitoba is more than one of Canada's three prairie provinces. Encompassing 649,950 square kilometres, its territory ranges from Canadian Shield to grassland, parkland, and subarctic tundra. Its physical geography has been shaped by ice-age glaciers, while its human geography reflects the influences of its various inhabitants, from the First Nations who began arriving over 9,000 years ago, to its most recent immigrants. This fascinating range of geographical elements has given Manitoba a distinct identity and makes it a unique area for study. Geography of Manitoba is the first comprehensive guide to all aspects of the human and physical geography of this unique province. Representing the work of 47 scholars, and illustrated with over 200 maps, diagrams, and photographs, it is divided into four main sections, covering the major areas of the province's geography: Physical Background; People and Settlements; Resources and Industry; and Recreation.As well as studying historical developments, the contributors to Geography of Manitoba analyse recent political and economic events in the province, including the effect of federal and provincial elections and international trade agreements. They also comment on future prospects for the province, considering areas as diverse as resource management and climatic trends.

Understanding the ebb and flow of materials on the earth's surface is vital to comprehending environmental change. We need to differentiate between those that represent a progression of natural events from those that might be human induced. The latter can be managed by changing policies; the former probably cannot. This volume presents what researchers know and do not know about the base (or natural) level of surficial fluxes and their dynamics. Leading experts in the field offer a historical perspective on geofluxes and discuss the cycles of materials on the earth's surface, from weathering processes to the movement of material through the river system and oceans to their deposition. The committee sets research directions in five areas: shallow-water studies, mapping, rates of change, sample dating, andâ€"most criticalâ€"understanding whether human influence can exceed the natural variability in geoflux processes. This volume will be important reading for geophysical scientists, researchers, faculty, and students, as well as environmental policymakers.

In recent years there has been a marked increase in funding andemployment in river restoration. Methods in Fluvial Geomorphologyprovides an integrated approach to the interdisciplinary nature ofthe subject and offers guidance for researchers and professionalson the tools available to answer questions on river management onvery difference scales. * Each chapter is organised to cover everything from generalconcepts to specific techniques * Topics covered include evolution of methods, guiding concepts, aframework for deciding when to apply specific tools, advantages andlimitation of the tools, sources of data, equipment and suppliesneeded, and a summary table * Provides the professional with a useful handbook covering alltools used in fluvial geomorphology * Also provides valuable information on the advantages andlimitations of the tools * All chapters include case studies to give examples of theapplications of the tools discussed

Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
