A practical guide to the latest techniques to measure sediments, seabed, water and transport mechanisms in estuaries and coastal waters. Covering a broad range of topics, enough background is included to explain how each technology functions. A review of recent fieldwork experiments demonstrates how modern methods apply in real-life scenarios.

This is the first interdisciplinary book on the mobilization of nutrients and pollutants in the water phase due to hydrodynamic processes. Coverage includes the formation of aggregates in turbulent water; flocks and biofilms from organic reactions; and the formation of new surfaces for re-adsorption of dissolved pollutants. The book gathers papers resulting from an International Symposium on Sediment Dynamics and Pollutant Mobility in River Basins in Hamburg, Germany, March, 2006.

The original idea of this book started when we were making a residual fluxes study of the Paranagua Coastal Lagoon (Brazil) near the colonial town of Guaraque~aba.Among the beautiful mangroves of this Brazilian National Park, between profile and profile, we wondered why South American estuaries were little known in the international arena. Besides, most of the papers published in the literature are based on biological research. Practically nothing is known about their geomorphology and dynamics. That night, while we were walking along the hilly streets of the town, we decided that the only way to have an idea about the degree of advance in the geomorphology and dynamics of our estuaries was to ask the proper South American researchers to write review articles about the estuaries in which they were working or about the gen eral state of the art of the Geomorphology and Physical Oceanography of the estuar ies of his/her country. The book grew from then on. Although initially many scien tists offer to write a chapter, we ran into the same problem these researchers have to publish in journals, they felt that their English was not good enough and withdrew. However, we are very satisfy about the number and quality of the contributions which also passed a very strong review process.

Hardbound. The INTERCOH series of conferences bring together the world's leading researchers and practitioners in cohesive sediment transport processes to share recent insights. This book presents papers that examine the spectrum of fine sediment transport related science and engineering, including the basics and applications of flocculation, settling, deposition, and erosion, advanced numerical models used in engineering practice, and applications to mud flats and harbor siltation.

Coastal Wetlands, Second Edition: An Integrated and Ecosystem Approach provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide. As coastal wetlands are under a great deal of pressure from the dual forces of rising sea levels and the intervention of human populations, both along the estuary and in the river catchment, this book covers important issues, such as the destruction or degradation of wetlands from land reclamation and infrastructures, impacts from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. Covers climate change and its influence on coastal wetland form and function Provides a fully updated and expanded resource, including new chapters on modeling, management and the impact of climate change Contains full-color figures of wetlands and estuaries in different parts of the world

It is a well-known fact that eutrophication of coastal waters causes significant changes in the species composition of the primary producers. Usually a shift from an ecosystem dominated by sea grasses or large brown algae to an ecosystem dominated by fast-growing green algae or phytoplankton is observed. While this shift has been documented in a number of research papers and books, the consequences of this shift are less well known. This book focuses on the consequences of such changes for nutrient cycling. The aim is to investigate how different types of primary producers influence nutrient cycling in coastal marine waters, and how nutrient cycling changes qualitatively and quantitatively as a consequence of the changes in the primary producer community caused by eutrophication. The various chapters address specific ecological processes such as grazing, decomposition, burial and export of biomass from the ecosystem. The book is intended for researchers and professionals working in the field of coastal marine ecology and estuarine ecology and for advanced students in this field.

Estuarine Processes, Volume II: Circulation, Sediments, and Transfer of Material in the Estuary provides information pertinent to estuarine processes and focuses on dynamic interactions at several levels of organization. This book describes the effects of physical alterations on estuarial hydraulics, dissolved and particulate material support, and on aquatic biota. Organized into six parts encompassing 27 chapters, this volume begins with an overview of the historic changes in salinity balance in the estuarial zone of the Sacramento-San Joaquin Delta. This text then reviews the effect of enlargement of artificial waterway of the Chesapeake and Delaware Canal, which has resulted in substantial alterations of the physical hydrography, biotic populations and chemical environment of the canal and its approaches. Other chapters consider the elements in a mathematical model for estuarial sediment transport. This book discusses as well sediment transport rates in coastal waters. The final chapter deals with accurate estimates of fish abundance for models of many estuarine processes. This book is a valuable resource for ecologists, environmentalists, and scientists.

Hydroinformatics systems are systems that combine computational hydraulic modelling with information systems (including knowledge-based systems). They are gaining rapid acceptance in the areas of environmental planning, design and management. The present book focuses exclusively on sewage systems, starting with their planning and then going on to discuss their design, operation and rehabilitation. The very experienced authors discuss business and information needs in the management of urban drainage, tools for collecting and archiving such data, and their use in modelling catchment hydrology, sewer systems hydraulics, wastewater quality, wastewater treatment plant operation, and receiving waters. The control and operation of sewer systems in real time is described, followed by a discussion of their maintenance and rehabilitation. Intelligent decision support systems for managing the urban drainage business process are presented. Audience: Researchers into sewer design, municipal engineers, planners and managers interested in an innovative approach to all aspects of the planning, design and operation of sewer systems.

The emphasis now placed on the concept of sediment cells as boundaries for coastal defence groups, and the development of SMPs, should help CPAs realise the importance of natural processes at the coast when designing defence and protection schemes. However, this will only be the case where defence groups exist, and where CPAs take up the challenge of developing SMPs. Coastal landscapes have been produced by the natural forces of wind, waves and tides, and many are nationally or internationally important for their habitats and natural features. Past practices at the coast, such as the construction of harbours, jetties and traditional defence systems may have contributed to the deterioration of the coast. English Nature (1992) have argued that if practices and methods of coastal defence are allowed to continue, then coastlines would be faced with worsening consequences, including: The loss of mudflats and the birds which live on them Damage to geological Sites of Special Scientific Interest (SSSIs) and scenic heritage by erosion, due to the stabilisation of the coast elsewhere Cutting of sediment supplies to beaches resulting in the loss of coastal wildlife Cessation through isolation from coastal processes, of the natural operation of spits, with serious deterioration of rare plants, animals and geomorphological and scenic qualities (English Nature, 1992) A number of designations, provided by national and international legislation do exist to aid conservation.
