Sediment Fluxes in Coastal Areas by Mohamed Maanan,Marc Robin Pdf

This book presents a detailed analysis and synthesis of the processes affecting sediments fluxes from watershed to worldwide coastal systems. The volume provides a comprehensive overview and constitutes a systematic description of the response of coastal systems to global and local changes, like climate change, sea level, land use and land cover change. The case studies cover a sequence of coastal environments such as lagoons, bays, estuaries, deltas and beaches. Sediment Fluxes in Coastal Areas is designed for researchers, professionals and for course-use in hydrology, oceanography, geography, geology, geomorphology and environmental science.

Modeling and Practice of Erosion and Sediment Transport under Change by Mohamed Meddi,Gil Mahé,Hafzullah Aksoy Pdf

Climate and anthropogenic changes impact the conditions of erosion and sediment transport in rivers. Rainfall variability and, in many places, the increase of rainfall intensity have a direct impact on rainfall erosivity. Increasing changes in demography have led to the acceleration of land cover changes in natural areas, as well as in cultivated areas, and, sometimes, in degraded areas and desertified landscapes. These anthropogenized landscapes are more sensitive to erosion. On the other hand, the increase in the number of dams in watersheds traps a great portion of sediment fluxes, which do not reach the sea in the same amount, nor at the same quality, with consequences on coastal geomorphodynamics. This book is dedicated to studies on sediment fluxes from continental areas to coastal areas, as well as observation, modeling, and impact analysis at different scales from watershed slopes to the outputs of large river basins. This book is concentrated on a number of keywords: “erosion” and “sediment transport”, “model” and “practice”, and “change”. The keywords are briefly discussed with respect to the relevant literature. The contributions in this book address observations and models based on laboratory and field data, allowing researchers to make use of such resources in practice under changing conditions.

The Effects of Woody Debris on Sediment Fluxes in Small Coastal Stream Channels by P. R. Commandeur,Brian Thomas Guy,Hugh Hamilton,Pacific Forestry Centre Pdf

Describes research on two first-order streams on the British Columbia south coast which were studied to determine the role of woody debris in controlling the routing and storage of sediment within high-gradient channels in logged areas. Two similar channels were selected, one with slash removed from the channel prior to the start of the experiment, and the other a control channel with no modification following harvest. Two methods were used to quantify sediment movement and changes in sediment storage in the control and treated channels: cross-sectional channel profiles and bedload tracers. Sediment outputs were measured using a combination sediment box and weir installed at the downstream limit of each test reach. Potential sources of sediment were also identified. By employing a sediment budget approach, an attempt is made to quantify inputs, outputs, and changes in storage in the test channels.

Sediment Transport in Coastal Waters by Sylvain Ouillon Pdf

The interface of 440,000 km long coastline in the world is subject to global change, with an increasing human pressure (land use, buildings, sand mining, dredging) and increasing population. Improving our knowledge on involved mechanisms and sediment transport processes, monitoring the evolution of sedimentary stocks and anticipating changes in littoral and coastal zones is essential for this purpose. The special issue of Water on “Sediment transport in coastal waters” gathers thirteen papers which introduce the current revolution in the scientific research related to coastal and littoral hydrosedimentary dynamics, and reflect the diversity of concerns on which research in coastal sediment transport is based, and current trends — topics and preferred methods — to address them.

Mitigating Shore Erosion Along Sheltered Coasts by National Research Council,Division on Earth and Life Studies,Ocean Studies Board,Committee on Mitigating Shore Erosion Along Sheltered Coasts Pdf

Like ocean beaches, sheltered coastal areas experience land loss from erosion and sea level rise. In response, property owners often install hard structures such as bulkheads as a way to prevent further erosion, but these structures cause changes in the coastal environment that alter landscapes, reduce public access and recreational opportunities, diminish natural habitats, and harm species that depend on these habitats for shelter and food. Mitigating Shore Erosion Along Sheltered Coasts recommends coastal planning efforts and permitting policies to encourage landowners to use erosion control alternatives that help retain the natural features of coastal shorelines.

Treatise on Estuarine and Coastal Science by Anonim Pdf

The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics

Kenya: A Natural Outlook by Christine A. Omuombo,Daniel O. Olago,Eric O. Odada Pdf

This chapter focuses on the existing information on the hydrodynamics and sediment transport processes along the Kenyan coastline. Although the low-lying coastline is under threat from coastal erosion that has led to its destabilization, the factors are linked to local and global processes. Changes in land used for agriculture have led to increase sediment fluxes which have resulted in increase in turbidity and siltation. Other activities such as coral and mangrove harvesting, seawall construction, urbanization and lack of regulations on the construction of structures along of the coastline can be linked to the coastal erosion processes. Among the global factors, the Kenyan coastline has been affected by the extreme events such as the El Niño event of 1997/1998, which led to devastating effects such as an increase in sediment fluxes and turbidity, coral bleaching and mortality and substantial sea level rise. A 1.3 °C sea surface temperature rise on the western side of the Indian Ocean has been recorded since 1880; this makes the coastline vulnerable to the impacts of the predicted 6 °C temperature rise in East Africa due to climate change. It is estimated that the biggest coastal city of Mombasa will be 17% submerged by 2100 and the Tana delta will experience a 5% loss as a consequence of climate change due to the frequent storms that are anticipated. Although the 2004 global tsunami events did not have devastating effects on the Kenyan coast, the event hit the coastline at low tide and this led to the limited damage. In the management of the shoreline, currently an Integrated Coastal Zone Management strategy does not exist although efforts are underway to develop a shoreline management strategy that incorporates the principles of the integration in the management of the coastline. These efforts are encouraged by the success of the marine protected areas of Malindi and Watamu and the current co-management strategy adapted by the Ministry of Fisheries through the Beach Management Units that engages the resource users as equal partners in the management of the coastal resources.
