LA PREMIERE PARTIE DE CE MEMOIRE S'ATTACHE A EVOQUER L'ENVIRONNEMENT (SITUATION ET PRINCIPAUX PARAMETRES) A DEFINIR LE DISPOSITIF EXPERIMENTAL AYANT SERVI A LA COLLECTE DES DONNEES (DIFFERENTES PARCELLES, AGRICOLES OU NON). LA DEUXIEME PARTIE ETUDIE LES PHENOMENES D'EROSION PLUVIALE, ELLE ANALYSE ET INTERPRETE HUIT ANNEES DE MESURES CONCERNANT LES PLUIES, LE RUISSELLEMENT, LES TRANSPORTS DE PARTICULES, A LA SUITE D'UNE ANALYSE DE LA GRANULOMETRIE DE LA CHARGE TRANSPORTEE, LES PERTES ET LES BILANS GEOCHIMIQUES SONT ETABLIS, EN LIAISON AVEC LA DYNAMIQUE DES SOLS. L'ETUDE S'ELARGIT ENSUITE PAR L'EXAMEN DE BASSINS-VERSANT (RIVIERE DES PLUIES, RAVINE MERE CANAL), DE LEUR FONCTIONNEMENT HYDROLOGIQUE (CRUES ET TRANSPORTS). LA TROISIEME PARTIE EST COMPARATIVE : INTERET ET LIMITES DES DEUX TYPES DE SYSTEMES, EXAMEN DES DIFFERENTS MODELES POUR LES CRUES ET L'EROSION. FINALEMENT, ON CLASSE L'ILE DE LA REUNION PARMI LES SECTEURS A TRES FORTS TAUX D'EROSION NATURELLE ET ANTHROPIQUE.

Book Description
An editorial by Wanless (1982), entitled "Sea level is rising - so what?", tells the case of an executive editor of a major city newspaper, who, when confronted with evi dence for a recent sea-level rise, replied: "That just means the ocean is six inches deeper, doesn't it?". Whether his "so what?" attitude was real or put on to dike a threat of sensation, there is at present a wide and deepening interest in ongoing and future global sea-level change. This interest has grown along with the concern over global warming due to increasing levels of C02 and trace gases. A stage has been reached where investigators of climat- sea-level relationships call for long-term measurement programmes for ice-volume changes (using satellite altimetry) and changes in temperature and salinity of the oceans (ther mal expansion). This manual, however, is primarily concerned with sea level changes in the past, mainly since the end of the last glaciation. Its major objective is to help answer the ques tion: "how?", which, of course, is little else but to assist in the gathering of fuel for the burning question: "why?" Good fuel, hopefully, for the less smoke and ashes, and the more heat and light produced by that fire, the better scientists are enabled to develop a quantitative under standing of past, and hence of future, sea-level changes on different spatial and temporal scales.

Book Description
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.
