Dans le cadre d'un contrat d'étude IBM (I), nous avons réalisé un système d'informations géographiques (S.I.G.) orienté image et intitulé GIPSY, pour Geographical Information and Processing System. La configuration matérielle est notamment caractérisée par un PS2/80 et une carte graphique 8514/A. Le logiciel est développé en Pascal sous DOS. Le système est composé de différents modules, dont trois sont réservés à l'environnement de travail. Le module Image couvre toutes les fonctions nécessaires au traitement des données issues, no-tamment, de la télédétection. Le module S.I.G. est conçu, dès le départ, pour exploiter les facilités du mode image, mais il permet une manipulation totalement hybride (maillé-vecteur) des informations spatiales. Un module est réservé à la constitution d'images géographiques de synthèse, parmi lesquelles le modèle numérique de terrain (M.N.T.) et ses produits dérivés, et les modèles gravitaires tels que le modèle de potentiel.

Reliability and validity of groundwater analysis strongly depend on the availability of large volumes of high-quality data. Putting all data into a coherent and logical structure supported by a computing environment helps ensure validity and availability and provides a powerful tool for hydrogeological studies. A hydrogeological geographic information system (GIS) database that offers facilities for groundwater-vulnerability analysis and hydrogeological modelling has been designed in Belgium for the Walloon region. Data from five river basins, chosen for their contrasting hydrogeological characteristics, have been included in the database, and a set of applications that have been developed now allow further advances. Interest is growing in the potential for integrating GIS technology and groundwater simulation models. A "loose-coupling" tool was created between the spatial-database scheme and the groundwater numerical model interface GMS (Groundwater Modelling System). Following time and spatial queries, the hydrogeological data stored in the database can be easily used within different groundwater numerical models. [less ▲]

Abstract: Landslides in Central Africa represent a constant threat to the population. The present work took its motivation from the increasing number of recorded incidents in recent times. It is focused on the analysis of mass movements in a regional context. Remote sensing based on the use of satellite images (Pleiades images of 2011) and aerial photographs (1957, 1958 and 1981) allowed us to identify instabilities at different scales. The study of these mass movements and the characterization of the processes governing ... [less ▲]

Testing whether rare species are limited by narrow habitat conditions from correlations between species occurrence and measured environmental factors is usually hampered by the lack of statistical power associated to the low number of observations. Aneura maxima is an exceedingly rare liverwort in Europe whose recent discovery precluded the inclusion within the Red Data Book of European bryophytes. A series of new observations resulting from intensive bryophyte grid-mapping at the border between France and Belgium allowed the statistical investigation of the factors accounting for its distribution at the landscape scale. The species was systematically observed in deep ravines on damp, loamy soils under light tree cover within broadleaf woodlands. These conditions differ from those of other European localities, suggesting that A. maxima is not limited by a narrow ecological range. Attempting to predict the occurrence of A. maxima at the landscape scale from data on land use and soil conditions resulted in a model where the species was actually observed in only a half of the squares where its probability of occurrence was the highest. The species thus does not seem to have colonized all its potential habitats, which may be explained by the poor dispersal ability of this dioecious, rarely fertile species. Given the relative frequency of A. maxima in the Semois river basin, but taking into account its seemingly low dispersal ability and its preference for swampy habitats that are threatened by draining and spruce plantations, a status as 'conservation dependent' to 'near threatened' within the category 'lower risk' is proposed.

Geographical information system (GIS) data on landscape features and land use were collected to predict bryophyte diversity and conservation value in order to determine the factors that favour bryophytes at a large geographical scale and propose the relevant conservation measures. Total species diversity and diversity in species of high conservation value were highly correlated, and the landscape features promoting them were the proportion of military lands, steep slopes, and broadleaf woodland. Military lands seemed to be especially important for the conservation of endangered species highly specialized to open habitats maintained by the appropriate level of disturbance. Woodland cover was also as a key factor for bryophyte diversity but landscape heterogeneity, such as steep slopes with a range of contrasting ecological conditions, was required to reach the highest species numbers. The GIS-based approach presented here may help focusing the attention on sites exhibiting the appropriate landscape features in terms of conservation, which is especially relevant in the context of the European network 'Natura 2000' for designating, conserving, and managing the sites of high biological value.

L'argile est une matière première abondante à la surface de la Terre. En raison de ces propriétés physico-chimiques, elle possède une grande variété d'utilisations. Le Maroc est l'un des plus grands consommateurs au monde d'argiles, cependant, le domaine majoritaire d’utilisation d’argiles est celui de la céramique. Dans la région de Marrakech, les argiles sont surtout utilisées dans les domaines de basse classe tels que la céramique traditionnelle et la poterie. Jusqu’à présent très peu d’études sont effectués pour valoriser ces argiles. C’est dans cet objectif que s’inscrit l’étude que nous menons sur les argiles du Haut Atlas de Marrakech ; le présent travail a pour objectif de dresser un inventaire des principaux gisements d’argiles de cette région. Les séries du Primaire (en particulier le Viséen) de la région de Marrakech ne sont pas assez altérées pour exploiter les argiles, tel est le cas de la région de Benhmed qui approvisionne les usines céramiques de la région de Settat. Dans les formations triasiques, malgré l'épaisseur et l'apparence argileuse des séries, seuls quelques gisements d'argiles y sont exploités pour la poterie. Les faciès triasiques, riches en illite, sont en effet silteux et assez pauvres en argiles à l'exception de quelques niveaux très minces. Ces argiles sont utilisées au niveau d’Ourika pour la fabrication d’ustensiles rustiques, pots de terre et objets ornementaux. Ces argiles peuvent également constituées des matières premières pour l’élaboration de briques et de substrats pour le revêtement des murs et des sols. Les argiles des formations jurassiques et crétacées sont assez riches en carbonates, ce qui ne convient pas à leur utilisation dans l’industrie céramique. Les séries du Paléocène et de l’Eocène de toute la région sont riches en argiles fibreuses non exploitées, surtout la palygorskite (argile avec de grandes propriétés physiques), ce qui donne des perspective d’utilisation dans des différents domaines industriels. Le Mioplicoène largement développé au pied du Haut Atlas est surtout connu par sa richesse en smectite, plus particulièrement dans la région de Tassaout. En ce qui concerne les séries quaternaires, certains niveaux d’alluvions sont exploités dans la région pour l’industrie céramique (site potier de Tamsloht, Briqueterie Menara,…). Dans la région de Bouchane, le sol quaternaire est considéré comme la seule source d’argiles et d’ustensiles dans cette zone. Enfin des dépôts actuels sont également exploités (limons des oueds Tensift et N’fis, canal la Rocade) pour la fabrication de briques de murailles ou additionnés à d’autres argiles pour augmenter la consistance des pâtes céramiques.
