This book was released on 1999 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: LA REDUCTION DE LA POLLUTION DES EAUX PLUVIALES URBAINES EST UN ENJEU ENVIRONNEMENTAL MAJEUR DEPUIS UNE TRENTAINE D'ANNEES. DES REJETS URBAINS DIVERS SONT TRANSPORTES DANS LA VILLE VIA LE CYCLE DE L'EAU POUR REJOINDRE LE MILIEU NATUREL. LE DEVELOPPEMENT DE LA CONNAISSANCE ET DE LA COMPREHENSION DES PROCESSUS PHYSICO-CHIMIQUES MIS EN JEU LORS DU TRANSPORT DE DIFFERENTS POLLUANTS SONT INDISPENSABLES POUR UNE MEILLEURE GESTION DU TRAITEMENT DES EAUX PLUVIALES (EN AMONT COMME EN AVAL). DANS LE BUT DE CARACTERISER ET DE COMPRENDRE LE TRANSPORT ET L'EVOLUTION DES FORMES CHIMIQUES DES METAUX TRACES EN MILIEU URBAIN, DEUX PROGRAMMES DE RECHERCHE SE SONT ASSOCIES : LE BASSIN VERSANT URBAIN EXPERIMENTAL ET LE PIREN-SEINE. UN BASSIN VERSANT EXPERIMENTAL A ETE CHOISI ET EQUIPE DANS LE QUARTIER DU MARAIS A PARIS AFIN D'ETUDIER LE TRANSFERT DE LA POLLUTION METALLIQUE DEPUIS L'ATMOSPHERE JUSQU'A L'EXUTOIRE, PAR TEMPS SEC ET PAR TEMPS DE PLUIE. CE BASSIN VERSANT DE 42 HECTARES, IMPERMEABILISE A 90% ET DONT LES EAUX SONT DRAINEES PAR UN RESEAU D'ASSAINISSEMENT UNITAIRE, EST CARACTERISTIQUE D'UN CENTRE VILLE ANCIEN. SON RESEAU DE COLLECTE A PLUSIEURS NIVEAUX DU CYCLE DE L'EAU (ATMOSPHERE, TOITURES, COURS INTERNES, CHAUSSEES, EXUTOIRE) EST UNIQUE EN SON GENRE. LES METAUX TRACES ONT ETE ETUDIES DE MAI 1996 A OCTOBRE 1997, PERIODE PENDANT LAQUELLE 20 EVENEMENTS PLUVIEUX ONT ETE INTERCEPTES. LES CONCENTRATIONS TOTALES ET DISSOUTES, LES TENEURS, LES REPARTITIONS ENTRE LES PHASES DISSOUTE ET PARTICULAIRE ET LES FLUX DE CADMIUM, DE CUIVRE, DE PLOMB ET DE ZINC PRESENTENT UNE EVOLUTION SIGNIFICATIVE ENTRE L'AMONT ET L'AVAL DE CE BASSIN VERSANT AINSI QU'UNE VARIABILITE IMPORTANTE. AU NIVEAU DU COMPARTIMENT ATMOSPHERIQUE, LES METAUX TRACES SONT PRINCIPALEMENT DEPOSES PAR VOIE SECHE (DE L'ORDRE DE 80%) ET SONT TRANSPORTES PAR LA PLUIE SOUS FORME DISSOUTE (DE 65 A 95%). LA NATURE ET LES CARACTERISTIQUES DE CHAQUE SURFACE URBAINE INFLUENT SUR LA CHARGE METALLIQUE DES EAUX RUISSELEES. LES EAUX DE RUISSELLEMENT DES TOITURES PRESENTENT LES CONCENTRATIONS METALLIQUES TOTALES LES PLUS ELEVEES DU BASSIN VERSANT ETUDIE : ELLES SONT FORTEMENT CONTAMINEES DU FAIT D'UNE DISSOLUTION PARTIELLE DES MATERIAUX DU TOIT ET DE LA DESCENTE DE GOUTTIERE DUE A L'ACIDITE DE LA PLUIE. A L'EXUTOIRE DU BASSIN VERSANT, APRES TRANSPORT DANS LE RESEAU D'ASSAINISSEMENT, LES CONCENTRATIONS METALLIQUES TOTALES DIMINUENT PAR RAPPORT A CELLES MESUREES DANS LES EAUX DE RUISSELLEMENT DE TOITURES ET LA FORME METALLIQUE PARTICULAIRE DEVIENT MAJORITAIRE (DE L'ORDRE DE 90%). CE PHENOMENE S'ACCOMPAGNE D'UNE STABILISATION DES FORMES METALLIQUES ET TEND AINSI A DIMINUER AINSI LA BIO-DISPONIBILITE DES METAUX PARTICULAIRES EN AVAL DE CE BASSIN VERSANT. A L'ECHELLE DE L'EVENEMENT PLUVIAL, LES EAUX DE RUISSELLEMENT SONT LA PRINCIPALE SOURCE DE METAUX SUR CE BASSIN VERSANT. LES BILANS DE MASSES ENTREES / SORTIE (METAUX DISSOUS ET PARTICULAIRES) DEMONTRENT QUE LE RESEAU D'ASSAINISSEMENT EST UN LIEU OU SE PRODUISENT DES PROCESSUS PHYSICO-CHIMIQUES NOMBREUX ET RAPIDES. LA PLUIE PROVOQUE L'EROSION D'UNE FRACTION DES DEPOTS CONSTITUES DANS LES COLLECTEURS ET CONTRIBUE AINSI A LA POLLUTION METALLIQUE GLOBALE MESUREE EN AVAL DU BASSIN VERSANT. D'AUTRE PART, UNE FRACTION DE CES MEMES DEPOTS, QUE NOUS N'AVONS PU ENCORE IDENTIFIER, SE COMPORTE COMME UN PUITS A METAUX TRACES. DES REACTIONS D'ADSORPTION, DE PRECIPITATION OU ENCORE DE COMPLEXATION SUR LES PARTICULES EN SUSPENSION OU LES STOCKS EUX-MEMES PORRAIENT EXPLIQUER CE PHENOMENE.

Book excerpt: Water Pollution 2010 is the 10th International Conference in the series on Modelling, Monitoring and Management of Water Pollution. The conference, which has always been very successful, provides a forum for discussion amongst scientists, managers and academics from different areas of water contamination. The wealth of information exchanged in this international meeting will be of great benefit to all involved with water pollution problems. The environmental problems caused by the increase of pollutant loads discharged into natural water bodies requires the formation of a framework for regulation and control. This framework needs to be based on scientific results that relate pollutant discharge with changes in water quality. The results of these studies allow industries to employ more efficient methods of controlling and treating waste loads, and water authorities to enforce appropriate regulations regarding this matter.

Book excerpt: NOVATECH conferences are one of the most important conference series in the world on innovative technologies in urban drainage. Scientists and technicians meet over three days to share experiences from different continents, to see the most significant advances on this subject and to discover some innovative and original ideas, which are likely to be developed in the coming years. During NOVATECH '2001, nearly 130 authors presented papers and 430 people from 34 countries took part. From the papers presented, 15 papers have been selected by the international scientific committee to be published in this special issue; the authors have been allowed to enhance their paper to offer more complete information; these papers are representative of the quality and the subject of NOVATECH. The main topics developed during NOVATECH?2001 were: global strategies of stormwater management; best management practices techniques (source control, detention basin and retention / infiltration ponds); sewer systems and physical processes under wet weather conditions (hydraulic and transport of solids); treatment of urban wet weather effluents; and data acquisition, tools for studies, analysis and real time control management of drainage systems. These proceedings provide an essential reference for engineers, researchers and planners working on the problems of urban drainage and looking for new solutions.

Available in PDF, EPUB and Kindle. Book excerpt: Deux aspects sont à prendre en compte pour cadrer les travaux menés sur le transfert atmosphérique des polluants en milieu urbain. Premièrement, un vaste programme de recherche sur l'environnement de la Seine (PIREN-Seine) a pour objectif de progresser dans la compréhension du lien qui unit le fonctionnement de l'écosystème formé par tout le réseau hydrographique de la Seine et les activités humaines de l'ensemble du bassin versant. C'est dans ce sens qu'ont été menés les travaux sur les apports atmosphériques de polluants sur le bassin et leurs liens avec la contamination des différents types de milieux rencontrés. Deuxièmement, un Observatoire de la Pollution Urbaine (OPUR) a été mis en place afin de mieux appréhender le comportement des polluants au sein d'un bassin versant fortement urbanisé. Cette seconde approche a permis de suivre l'enrichissement des eaux de ruissellement des toitures et des chaussées, considérées comme des exutoires pour la pollution atmosphérique tout en étant des voies d'apport de polluants au sein du réseau d'assainissement.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'essor que connaît aujourd'hui la gestion intégrée des eaux pluviales s'accompagne d'un recours croissant à des techniques favorisant l'infiltration de l'eau “à la source”, disséminées sur des bassins versants urbains. Néanmoins, de telles pratiques suscitent des interrogations sur la capacité du sol à jouer le rôle de “filtre” vis-à-vis des polluants présents dans le ruissellement. Ces travaux de thèse s'intéressent à la contamination du sol par les métaux et les hydrocarbures aromatiques polycycliques (HAP) dans ces dispositifs, avec trois objectifs : (i) évaluer les niveaux et l'étendue spatiale de la contamination, (ii) mieux comprendre les mécanismes qui gouvernent le devenir de ces contaminants dans le sol des ouvrages, et (iii) proposer des recommandations sur la conception et la maintenance de ces installations, afin de leur assurer un fonctionnement épuratoire durable.La première partie du travail consiste en une série d'investigations expérimentales sur dix sites d'étude aux caractéristiques contrastées, en service depuis plus de dix ans. Cette phase donne lieu à des cartographies de la contamination superficielle en éléments traces métalliques, puis à des profils verticaux de métaux et HAP, accompagnés de différentes variables explicatives. La distribution spatiale des métaux en surface, qui est toujours structurée autour de la zone d'arrivée de l'eau, porte la signature du fonctionnement hydraulique réel des dispositifs, et révèle le caractère non-uniforme de l'infiltration lors des événements pluvieux courants, qui représentent la plus grande partie du flux polluant à l'échelle annuelle. Dans la zone la plus contaminée des ouvrages, métaux et HAP présentent un enrichissement significatif sur 10 à 40 centimètres de profondeur. La rétention des contaminants résulte de la combinaison de processus physico-chimiques (adsorption) et mécaniques (sédimentation et filtration) ; leur importance relative peut être quantifiée grâce au déficit de zirconium dans le sédiment urbain par rapport au bruit de fond géochimique local. La variabilité inter-sites des niveaux de contamination s'explique à la fois par les capacités de rétention du sol et par les flux de polluants issus du bassin versant d'apport. Bien que les teneurs de surface excèdent, sur certains sites, les seuils internationaux de remédiation du sol pour des espaces “multifonctionnels”, la zone concernée représente -- latéralement et verticalement -- une région assez limitée dans les ouvrages.La seconde partie de la thèse consiste en une approche de modélisation, dont la finalité est de décrire l'évolution à long terme de la contamination du sol, et d'évaluer l'incidence de différentes pratiques de conception ou de gestion. Une analyse de sensibilité est d'abord mise en œuvre afin d'identifier les “éléments-clés” dans la description du système, et d'orienter le choix du modèle. Les résultats montrent qu'une mauvaise estimation de la dispersivité ou de l'isotherme d'adsorption du sol est susceptible de biaiser significativement la prévision des profils de contamination. Dans la suite du travail, on propose une méthode visant à décrire l'infiltration non-uniforme et la filtration des polluants particulaires. Le modèle ainsi construit est validé via une comparaison entre mesures et simulations sur l'un des sites d'étude faisant l'objet d'une nouvelle caractérisation approfondie. Enfin, une analyse de scénarios illustre les bénéfices d'un amendement de l'horizon superficiel par un matériau adsorbant, ainsi que d'une répartition homogène des flux d'eau en surface, en matière de durée de vie des installations et de fréquence d'intervention.

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.

This book was released on 2015 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Mediterranean region hosts around 400 coastal lagoons, covering a surface of over 641 000 ha differing in both their typology and use. Fisheries and various forms of aquaculture have been traditionally carried out in Mediterranean coastal lagoons since ancient times and are part of the cultural heritage of the region. Traditional lagoon management linked to extensive aquaculture and fish harvesting has certainly contributed, over time, to preserve these peculiar ecosystems, although much of the coastal lagoon areas have progressively disappeared due to land reclamation and other uses. Recently, coastal lagoons have become a relevant environmental concern: land claiming, pollution and the lack of management, among other factors, have strongly modified both the structure and functioning of these sensitive coastal ecosystems. In particular, the management of traditional aquaculture and capture fisheries activities has been identified as the main instrument to maintain lagoons' ecological features and to prevent the degradation of their sensitive habitats, both from an environmental and socioeconomic point of view. To guarantee the sustainability of aquaculture and capture fisheries in lagoons, proper management plans should be established so as to ensure the preservation of both biodiversity and local knowledge. This should also be considered as a fundamental pillar for any programme aiming at the preservation and restoration of lagoons' environment."--Publisher's description.
