Book Synopsis La sédimentation fine sur une plate-forme interne actuelle macrotidale by : Sébastien Garnaud
Download or read book La sédimentation fine sur une plate-forme interne actuelle macrotidale written by Sébastien Garnaud and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: En Baie de Seine sud-orientale (shoreface à plate-forme interne), la sédimentation fine est étudiée à des échelles de temps variées, des dépôts holocènes argilo-tourbeux continentaux (9000 ans BP) aux événements de dépôt instantanés actuels liés à des "crues estuariennes". Lors de ces crues, succédant à de faibles débits prolongés, sont combinés les apports d'un stock de sédiments fins intra-estuariens et les MES originaires du bassin versant amont. Des placages de vase se mettent alors en place dans les petits fonds ouverts sableux. Ces fonds correspondent actuellement à un contexte d'ensemble érosif, où sont mises à l'affleurement les argiles holocènes; une reconstitution lithochronostratigraphique de ces dépôts fossiles est proposée. Il est montré l'importance: à l'échelle décennale et pluri-annuelle, d'un envasement progressif des sables subtidaux et, à l'échelle de la saison, d'épisodes paroxysmiques de dépôts de vase, éphémères remaniés par les houles et les courants de marée.
Book Synopsis Les Clapages de sédiments en mer by : Stella Marmin
Download or read book Les Clapages de sédiments en mer written by Stella Marmin and published by . This book was released on 2010 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chaque année en France, 50 millions de m3 de sédiment sont dragués afin de maintenir une profondeur suffisante dans les chenaux et les ports. Dans ce cadre, une étude visant à localiser et étudier un site de clapage de sédiments de plusieurs millions de m3 pour le port de Rouen pour les deux prochaines décennies a été lancée. Une zone prédéfinie a été choisie en fonction des différentes contraintes économiques, logistiques et environnementales. Les premiers dépôts de matériel de dragage seront effectués dans la partie orientale de la Manche en janvier 2011. Les objectifs seront d'évaluer l'impact sur l'écosystème, d'évaluer les périodes de récupération des communautés, de contrôler la dispersion des sédiments afin d'en déduire une méthode optimale de gestion pour le site. Récemment (déc 2009-avril 2010-juillet 2010), les sédiments et la macrofaune ont été échantillonnés sur un site de référence et sur les deux futurs sites de clapage. Le but est de caractériser la zone avant le dépôt de matériel dragué et d'obtenir un état de base antérieur au dépôt. Les premiers résultats indiquent que la zone est caractérisée une teneur en matière organique faible (2%) ; le faciès sédimentaire est caractérisé par des sables moyens dunaires propres à Nephtys cirrosa. Les échanges d'oxygène et d'ammonium à l'interface eau-sédiment ont été estimés par l'incubation de carottes de sédiment en laboratoire. Les résultats sont caractéristiques des sédiments perméables. En vue d'une décision publique, on peut supposer que cette région est favorable à recevoir des dépôts des déblais de dragage dont l'impact sera réduit par rapport à une zone riche peu profonde à l'embouchure de l'estuaire de la Seine.

Book Synopsis Water & Heritage by : Willem Willems
Download or read book Water & Heritage written by Willem Willems and published by . This book was released on 2017-01-15 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is vital for life, and its availability has been a concern for mankind throughout the ages. Its presence has always been ascertained in a variety of ways and the development of human society everywhere is connected with various forms of water management. Man also needed to manage water to find protection from its dangers and the need for that is increasing. In the coming decades, the impact of climate change is expected to intensify floods and droughts, affect groundwater resources, raise sea levels, increase pollution and enhance the frequency and magnitude of disasters. Societies around the world are challenged to adapt to these threats to ensure water security, economic prosperity and environmental and cultural sustainability. This book deals with the heritage of water management and the use that was made of water, as well as the impact of water management on heritage. An example of the former may be an ancient irrigation system in the Filipines or in the Middle East that still functions today, while the latter may reflect the importance of maintaining groundwater levels for the preservation of organic remains on archaeological sites or of wooden piles underneath standing buildings. In either case the papers in this book reflect the dynamic nature of water, and hence the equally dynamic relation between water management and heritage. This publication follows up on a Heritage and Water conference in Amsterdam, the first of its kind. Its main purpose is to credibly present the importance and value of heritage and historical experience for water and sustainable development, and vice versa, present the importance of water management for the protection of heritage. It presents evolving insights and concepts about Water and about Heritage from a variety of disciplines, policy and public perspectives illustrated with cases studies and aims to connect decision makers with experts such as engineers, archaeologists, historians, geographers, ecologist and landscape architects
Book Synopsis Coastal Marine Ecosystems of Latin America by : U. Seeliger
Download or read book Coastal Marine Ecosystems of Latin America written by U. Seeliger and published by Springer Science & Business Media. This book was released on 2000-10-18 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental settings, biotic components and structure of the system, considers trophic processes and energy flow, evaluates the modifying influence of natural and human perturbations, and suggests management needs. Although the focus of the book is on basic ecological research, the results have application for coastal managers.

Book Synopsis Evolution of Marine Coastal Ecosystems under the Pressure of Global Changes by : Hubert-Jean Ceccaldi
Download or read book Evolution of Marine Coastal Ecosystems under the Pressure of Global Changes written by Hubert-Jean Ceccaldi and published by Springer Nature. This book was released on 2020-06-15 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal and estuarine environments at the interface of terrestrial and marine areas are among the most productive in the world. However, since the beginning of the industrial era, these ecosystems have been subjected to strong anthropogenic pressures intensified from the second half of the 20th century, when there was a marked acceleration in the warming (climate change) of the continents, particularly at high latitudes. Coastal ecosystems are highly vulnerable to alteration of their physical, chemical and biological characteristics (marine intrusion, acidification of marine environments, changes in ecosystems, evolution and artificialization of the coastline, etc.).In contact with heavily populated areas, these environments are often the receptacle of a lot of chemical and biological pollution sources that significantly diminish their resilience. In this context of accelerated evolution and degradation of these areas important for food security of many populations around the world, it is necessary to better identify the factors of pressure and understand, at different scales of observation, their effects and impacts on the biodiversity and on the socio-eco-systems, in order to determine the degree of vulnerability of these coastal ecosystems and the risks they face. A transdisciplinary and integrated approach is required to prevent risks. Within this framework, operational coastal oceanography occupies an important place but also the implementation of a true socio-eco-system approach in order to set up an environmentally friendly development.
