POUR EVALUER LA DISPERSION DANS L'ATMOSPHERE DES REJETS INDUSTRIELS DE LA REGION DE FOS-SUR-MER, UN MODELE "BOUFFEES" TRIGAUSSIEN, CARACTERISE PAR LES ECARTS-TYPES PARAMETRES, EN FONCTION DU TEMPS DE TRANSFERT POUR 2 CLASSES DE STABILITE VERTICALE DE L'ATMOSPHERE, A ETE DEVELOPPE. CETTE RECHERCHE ENTRE DANS LE CADRE DES ETUDES REALISEES POUR TRAITER LES DONNEES OBTENUES LORS DE LA CAMPAGNE DE MESURE ORGANISEE PAR LES COMMUNAUTES EUROPEENNES. LE MODELE, PAR SA FORME ANALYTIQUE, PERMET DE PRENDRE EN COMPTE LES PHENOMENES LES PLUS IMPORTANTS QUI MODIFIENT LE CONTENU DE LA BOUFFEE AU COURS DU TRANSFERT : REFLEXIONS, DEPOTS SEC ET HUMIDE, TRANSFORMATION PHYSICO-CHIMIQUE DU POLLUANT SO::(2). IL TIENT COMPTE DES PARAMETRES METEOROLOGIQUES DU SITE MESURES DANS LES TROIS DIMENSIONS (VITESSE ET DIRECTION DU VENT, AU SOL ET EN ALTITUDE) ET DES CARACTERISTIQUES DES DIFFERENTES CHEMINEES. EN OUTRE, IL PEUT AUSSI BIEN CALCULER LA POLLUTION CONSECUTIVE A UNE COURTE PERIODE D'EMISSION QUE CELLE RESULTANT D'EMISSIONS CONTINUES. DES EXEMPLES SONT PRESENTES

Book Description
Qualité de l'air, effet de serre, trou d'ozone, accidents chimiques ou nucléaires... Tous ces sujets ont en commun d'être étroitement liés à la composition chimique de l'atmosphère et à la dispersion atmosphérique de polluants. Cet ouvrage a pour objectif de donner les principaux éléments de compréhension des «pollutions atmosphériques». Quels sont les enjeux? Quels sont les processus physiques impliqués? Quel rôle joue à présent l'expertise scientifique, fondée notamment sur la modélisation, pour l'aide à la décision? Ce livre d'adresse non seulement à des étudiants de master ou d'écoles d'ingénieurs, à de jeunes chercheurs ou à des enseignants, mais aussi à des professionnels en activité qui veulent avoir une vue synthétique et argumentée des sujets traités et plus généralement, à toute personne possédant un socle de culture scientifique et désireuse d'aller au-delà de la connaissance «grand-public». De nombreux exercices et problèmes permettent d'aborder des sujets d'actualité.

Book Description
We live in turbulent times with continents and nations facing ever-heightening risks such as natural disasters, intense and protracted conflicts, terrorism, corporate crises, cyber threats to infrastructures and mega-events. We are witnessing the rise of mega-crises and a new class of adversity with many unknowns. The prospect of mega-crises presents professionals and students in the field of crisis management with four major tasks. First, they should engage in “deep thinking” about the causes of the increasing occurrence of mega-crises. Second, they should identify and work through the dominant trends which complicate contemporary crisis management. Third, they should upgrade institutional crisis management capacity. Fourth, they should improve societal resilience since no institutional complex can mitigate or manage these mega-crisis on its own. This book is divided into four primary parts, each of which looks at one facet of mega-crises. Part I focuses on the concept of a mega-crisis and mega-crisis management; Part II examines crisis management of mega-natural disasters; Part III evaluates crisis management of man-made mega-crises; and Part IV identifies mega-threats and vulnerabilities. Additional major topics include Hurricane Katrina; Hurricane Gustav; the London Bombings; the Mumbai Terrorist Attacks of July 7, 2005; corporate meltdowns; the subprime crisis; the Olympic Games; electricity grids; global climate change; the Dutch Delta; risks to food security; and mega-crises and the Internet. This comprehensive text will provide practitioners and academics with the results of an across-the-board research effort in the prospects, nature, characteristics, and the effects of mega-crises.

Book Description
Expanding a port, deepening a navigation channel or creating new land for development, introduces changes to our physical, social, economic and political environment. Changes may result from events during the construction process, or relate to the nature of the completed structure. Changes can be positive or negative, short-term or long-term, and may affect the immediate vicinity of the project or a larger geographical area. Predicting and assessing all possible effects of a planned dredging activity in a scientifically-sound and reliable manner is essential, so that appropriate control measures can be taken to avoid or mitigate unwelcome impacts. This book provides guidance for a complete holistic environmental evaluation procedure and for the design and implementation of environmental control measures. The book is of particular interest to engineers, government agencies and port authorities, as well as civil engineering consultants and contractors involved in planning and designing dredging, maritime infrastructure and fluvial projects.
