This book was released on 1994 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: LA PRESENTE ETUDE CONSTITUE UNE APPROCHE DE LA QUANTIFICATION DU RISQUE NATUREL LIE AUX MOUVEMENTS DE TERRAIN A PARTIR DE LA SIMULATION DES DONNEES DE SURFACE ET DE LA MORPHODYNAMIQUE DES VERSANTS. NOUS AVONS DEFINI LA TYPOLOGIE DES INSTABILITES DES VERSANTS ET EFFECTUE LEUR RECENSEMENT DANS LE SITE DE LA VILLE DE TAOUNATE (RIF, MAROC) AU COURS DE PLUSIEURS MISSIONS DE TERRAIN ET AVEC L'APPORT PERMANENT DE LA PHOTO-INTERPRETATION. L'ETUDE DETAILLEE DE LA PENTE TOPOGRAPHIQUE, DE LA LITHOLOGIE ET DE LA GEOMORPHOLOGIE NOUS A PERMIS DE METTRE EN EVIDENCE LES RELATIONS MUTUELLES DES CARACTERISTIQUES INTRINSEQUES DES TERRAINS INSTABLES. CES TROIS COMPOSANTES CADRENT LES INSTABILITES DES VERSANTS ET FORMENT LES FACTEURS DE RISQUE POUR LA CONTRIBUTION DE CET ESSAI METHODOLOGIQUE DE LA CARTOGRAPHIE DES RISQUES NATURELS. LA QUANTIFICATION DU RISQUE EST BASEE SUR DES CALCULS DE RAPPORTS DE SURFACES: EN RECHERCHANT LA PENTE LIMITE D'EQUILIBRE NATURELLE DE CHAQUE FACIES, EN CALCULANT LE DEGRES D'INSTABILITE DES FACIES (RAPPORT DES SURFACES INSTABLES SUR LES SURFACES TOTALES DES AFFLEUREMENTS), ET EN CLASSANT LES TYPES D'INSTABILITE EN FONCTION DES DEGATS OCCASIONNES OU QU'ELLES PEUVENT OCCASIONNER. NOUS AVONS DEFINI AINSI DES INDICES DE RISQUE SELON UNE ECHELLE NUMERIQUE. CETTE SYSTEMATISATION GRAPHIQUE NOUS A CONDUIT A TRANSCRIRE LES CARTES DE FACTEURS EN CARTES DE SIMULATION DU RISQUE (CARTES NUMERIQUES). LE RISQUE GLOBAL DE L'ACTION SIMULTANEE DES FACTEURS DETERMINANT A ETE EVALUE SELON DEUX TYPES: EVALUATION ARITHMETIQUE ET EVALUATION PROBABILISTE. LA COMPARAISON DE CES DEUX DEMARCHES FAIT RESSORTIR QUE L'APPROCHE PROBABILISTE DONNE UNE PRECISION DU NIVEAU DU RISQUE ET S'ACCORDE MIEUX AVEC SA DEFINITION. LA CARTE DES RISQUES NATURELS QUI EN RESULTE EXPRIME DES PROBABILITES D'APPARITION SPATIALE CLASSEES SUIVANT DES DEGRES DE RISQUES CROISSANT: FAIBLES D1, 0 A 10% ; MOYEN D2, 10 A 30 ; ELEVE D3, 30 A 50 ; ET TRES ELEVE D4, 50 A 100%
Book Synopsis Aléas et risques naturels en montagne by : Anne Lacambre
Download or read book Aléas et risques naturels en montagne written by Anne Lacambre and published by . This book was released on 2001 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forme et processus d'érosion sont étudiés dans deux vallées alpines qui forment les sources du Drac (communes d'Orcières et de Champoléon, Hautes-Alpes, France).En plus de l'inventaire des secteurs touchés par les nombreux aléas et risques (avalanches, crues, coulées de débris, mouvements de terrain), la perception de ces risques par les habitants a été analysée.Mais, pour mieux comprendre le fonctionnement des processus d'érosion et surtout les causes de leur déclenchement, un Système d'Information Géographique (SIG) a été mis en place. Le maximum de paramètres du milieu est pris en compte, grâce à des cartes thématiques (données topographiques, climatiques, lithologiques, biogéographiques). Le croisement de toutes ces données est ensuite effectué pour créer cartes d'aléas et cartes de risques.Une réflexion sur la méthodologie développée a enfin été menée. En effet, le SIG, s'il présente quelques inconvénients, n'en demeure pas moins un outil nécessaire pour traiter en général des problèmes d'aménagement, et en particulier des aléas et risques naturels dans des communes de montagne où l'homme est confronté à de nombreux phénomènes d'érosion.

Download or read book La Caraïbe, données environnementales written by and published by KARTHALA Editions. This book was released on 2006 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: A l'interface des continents nord et sud américains, la Caraïbe se caractérise par de grandes disparités sociétales et biologiques. A la pluralité des environnements physiques correspond une diversité floristique, faunistique, écosystémique et paysagère. Ressource primordiale pour les Amérindiens, les écosystèmes terrestres et marins sont aujourd'hui à l'intersection d'intérêts divers relevant de l'économique et du culturel ou encore de l'aménagement territorial. Les spécificités écologiques, qui sont fonction des différentes terres caribéennes, sont à la base d'usages nouveaux susceptibles de participer au développement économique, par exemple le tourisme. A cette histoire singulière, façonnée par l'action des hommes, s'ajoutent les incommodités naturelles telluriques et atmosphériques, dont les effets directs et indirects ont érigé certaines composantes de cette partie de la biosphère en terre à risques. Les nuisances de toutes sortes, inhérentes au fonctionnement de ces sociétés, sont des freins au développement maîtrisé ou soutenable. Pour l'essentiel, les économies relèvent des propriétés du mal-développement et peuvent entraîner, dans des cas extrêmes, un chaos politique et social. Les conséquences pour les milieux biophysiques sont souvent graves et s'apparentent à un écocide (Haïti par exemple). Le but premier de ce numéro de Terres d'Amérique est d'explorer les différentes facettes du fonctionnement des sociétés caribéennes ainsi que leurs dynamiques d'interface au regard des environnements physiques et biologiques.

Book Synopsis Geomorphological Hazards of Europe by : C. Embleton
Download or read book Geomorphological Hazards of Europe written by C. Embleton and published by Elsevier. This book was released on 1997-04-07 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Geomorphological Hazards of Europe contains an excellent balance of authoritative statements on the range and causes of natural hazards in Europe. Written in a clear and unpretentious style, it removes myths and concentrates on the basic facts.The book looks at the known distributions, processes and the underlying principles and focuses on the need for a true understanding of the scientific details so that a real contribution to hazard management can be made.A comprehensive treatment of scientific and management issues of hazards in Europe caused by natural or sometimes human induced earth surface processes are covered including floods, landslides, avalanches, glacier-, coastal-, karstic-, and volcanic hazards, soil erosion and subsidence.Leading researchers in the field of natural hazards and their mitigation have contributed to this nation by nation account covering 20 European countries. The individual chapters deal with the distribution of natural hazards within specific countries (quite often the first synthesis of the information available) and • provide a review of current research in the field• discuss the economic, engineering and policy responses in national hazard management• are complemented by an extensive bibliography.The volume is well illustrated with 207 figures of which 66 are photos and has an extensive general index and a complete index of place names. It is a major European contribution to the International Decade for Natural Disasters Reduction.The book will appeal to practitioners, managers, academicians, researchers, as well as graduate students in geomorphlogy, natural hazards research and environmental management.
Book Synopsis Lake Pavin by : Télesphore Sime-Ngando
Download or read book Lake Pavin written by Télesphore Sime-Ngando and published by Springer. This book was released on 2016-10-31 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.
Download or read book Atlas of Lebanon written by Eric Verdeil and published by Presses de l’Ifpo. This book was released on 2019-10-03 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: After fifteen years of reconstruction in a relatively peaceful environment spanning the years 1990 to 2004, Lebanon has experienced successive violent political events resulting from complex entangled internal and external struggles. The Syrian crisis and its political, economic and demographic consequences on Lebanon have increased these tensions. This atlas sheds light on these new challenges and adds new data that complete the analyses already published in the Atlas du Liban. Territoires et société (Atlas of Lebanon. Territories and Society) released in 2007 by the same research team. Some of its components are included in this edition. Beyond the international regional crisis and the population movements, it takes into account Lebanon’s socio-economic dimensions, the environmental issues linked to uncontrolled urbanization and to natural risks, as well as conflicts due to local territorial management. This atlas is the result of a collaborative endeavor between French and Lebanese researchers. It uses a geographical approach that puts in the foreground a spatial analysis of social and natural phenomena. Public sources are scarce in Lebanon, especially at the local scale. They are sometimes less reliable and difficult to access. It is particularly the case for the Lebanese census data, conversely data are abundantly available on the refugees population, which is less known than the population of refugees. International data help compare Lebanon to its neighbors. Thematic data produced by some ministries are helpful to provide a detailed view regarding specific domains. Analyses processed on aerial and satellite images have produced essential data on urbanization and environment. Local thematic fieldwork surveys have provided additional data. The book consists of seven chapters. The first one deals with the territorial state-building seen in the light of regional geopolitics, and emphasizes internal violence and the reemergence of militias and armed groups that fight each other and the state army. Lebanon is once again perceived as a territory divided between multiple allegiances. The second chapter is devoted to the analysis of population dynamics, despite the lack of reliable data whose sources are subject to discussion. It includes analyses of internal population flows, the Lebanese diaspora, and the assessment of Syrian refugees’ influx. The third chapter shows the fragility of the Lebanese economic model. Its dependency on foreign investments and on...
