This book presents insights into the complex processes controlling sediment behavior in river basins and into state of the art integrated sediment management concepts. Main topics are: sediment transport, modelling sediment transfer in rivers, sediment quality, sediment monitoring and integrated sediment management at catchment scale. Interlinkages of sediment dynamics and quality with biogeochemistry, ecology, climate change and human activities are discussed. Drivers, boundary conditions and processes of erosion, sediment transport and sedimentation are presented with the aim to help the reader putting sediment quantity and quality issues into perspective.

A sound understanding of the global carbon cycle requires an appreciation of the various physico-chemical and biological processes that determine the production, distribution, deposition and diagenesis of organic matter in the natural environment. This book is a comprehensive interdisciplinary synthesis of this information, coupled with an organic facies approach based on data from both microscopy and bulk organic geochemistry.

Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.

In dynamic river systems, effective and sustainable risk management of sediments, contaminants and their sources must be carried out on a river basin scale. A diversity of interests and risk perceptions, whether environmental, economical, or personal, as well as the broad variety of uses and functions of river systems can lead to conflicts and disagreements about how and where river systems should be managed. This requires a transparent methodology to assess environmental risks in the river basin, followed by a prioritisation of those sites where measures would yield the highest positive effect for the river basin and where financial resources could be allocated most efficiently. However, risk perceptions may only partially be influenced by scientific assessments of risk, and often also depend on a variety of factors such as personal experience and confidence in institutions. Risk managers must develop methods to balance technical and socioeconomic issues with the aim to reduce risks posed by sediments to environmental and economic resources to a level that is perceived as tolerable by society. Sediment Risk Management and Communication (Vol.3 in the SEDNET mini-series) is based on discussions that were held in the working group on "Risk Management and Communication" which was one of 4 working groups within the European Demand-Driven Sediment Research Network "SedNet". It aims to analyse the current situation in Europe with regard to sediment risk management issues, to draw conclusions from this analysis and to offer recommendations for sustainable risk management from basin to site-specific scale. This volume also available as part of a 4-volume set, ISBN 0444519599. Discount price for set purchase. A broad overview on sediment quality and impact assessment of pollutants Suitable for both newcomers to the field of sediment treatment and specialists alike Outlines practical examples of methods used in sediment quality analysis

Historically, the flow of sediment in the Missouri River has been as important as the flow of water for a variety of river functions. The sediment has helped form a dynamic network of islands, sandbars, and floodplains, and provided habitats for native species. Further downstream, sediment transported by the Missouri and Mississippi Rivers has helped build and sustain the coastal wetlands of the Mississippi River delta. The construction of dams and river bank control structures on the Missouri River and its tributaries, however, has markedly reduced the volume of sediment transported by the river. These projects have had several ecological impacts, most notably on some native fish and bird species that depended on habitats and landforms created by sediment flow. Missouri River Planning describes the historic role of sediment in the Missouri River, evaluates current habitat restoration strategies, and discusses possible sediment management alternatives. The book finds that a better understanding of the processes of sediment transport, erosion, and deposition in the Missouri River will be useful in furthering river management objectives, such as protection of endangered species and development of water quality standards.
