In the framework of the disposal of short-lived low- and intermediate-level radioactive waste in a near-surface disposal facility in Dessel, Belgium, additional extensive site characterization has been performed in 2008. The gathered data now enclose 388 hydraulic conductivity measurements on samples of 8 cored boreholes. Additionally, secondary information as grain size analysis, resistivity, porosity, etc. was gathered. With this dataset, a small-scale probabilistic approach can be used 1) to validate the current existing deterministic groundwater models based on large-scale average hydraulic conductivity values, and 2) to support design for a monitoring network. In preparation for stochastic realizations of the subsurface, an exploratory and structural data analysis was performed and is presented here. The exploratory data analysis allows definition of hydrogeological units, independent from the existing lithostratigraphy. It also shows the presence of three conductivity classes within a strongly heterogeneous unit. Currently, only vertical structural data analysis is performed based on vertical data profiles. Semi-variograms and cross-variograms are calculated to characterize the spatial variance of the different hydrogeological units. Additional sampling and measurements will be performed in the future to provide information of the horizontal spatial variance. Together with the current results, these will serve as the basis for conditional stochastic simulation of groundwater flow and contaminant transport. [less ▲]

The use of unsupervised artificial neural network techniques like the self-organizing map (SOM) algorithm has proven to be a useful tool in exploratory data analysis and clustering of multivariate data sets. In this study a variant of the SOM-algorithm is proposed, the GEO3DSOM, capable of explicitly incorporating three-dimensional spatial knowledge into the algorithm. The performance of the GEO3DSOM is compared to the performance of the standard SOM in analyzing an artificial data set and a hydrochemical data set. The hydrochemical data set consists of 131 groundwater samples collected in two detritic, phreatic, Cenozoic aquifers in Central Belgium. Both techniques succeed very well in providing more insight in the groundwater quality data set, visualizing the relationships between variables, highlighting the main differences between groups of samples and pointing out anomalous wells and well screens. The GEO3DSOM however has the advantage to provide an increased resolution while still maintaining a good generalization of the data set. [less ▲]

Dating archaeological mortar by OSL is one of the challenging objectives leading to the chronology of ancient constructions. Single grain OSL analysis is a very convenient tool to examine the bleaching state of the series of quartz grains extracted from a mortar sample. Indeed, during the making process, sand is extracted from a sedimentary source, transported, stored then mixed with lime and set into the walls being constructed. Experience shows that incomplete bleaching is frequent for these materials. The aim of this study is to model the distribution of single grain equivalent doses of mortars following the assumption that a population of grains corresponds to a unique distribution of heterogeneously bleached grains rather than to a mixture of well bleached quartz grains with poorly bleached ones. An exponential distribution of light exposure of grains is examined. By comparing experimental distributions of doses with simulated ones, we investigate the appropriateness of this distribution function and then we calculate the average residual dose integrated into the process of the ED determination and finally the OSL age. Limits and potentials of this approach are discussed using various case-studies of structures and buildings of known age (from the roman to the post-medieval period). Even in case of very poorly bleached samples we observed that the simulated ED distribution fits satisfactorily with the experimental one, which offers new encouraging perspectives in single grain dating of mortars.

Une très modeste enquête sur l'exposé, menée en CFWB auprès d'enseignants du primaire et du secondaire supérieur, nous a permis de dresser ces deux constats. 1° Lors des activités scolaires d'exposé, l'attention est focalisée sur la performance : le plus souvent, ce qui devrait se faire en amont et en aval de celle-ci est passé sous silence ou négligé et, à tout le moins, ne donne pas lieu à des tâches préparatoires. 2° Les ressources à mobiliser avant, pendant et après la présentation d'un exposé font très rarement l'objet d'une programmation. Principalement adressé aux enseignants, à leurs formateurs et conseillers, le présent ouvrage peut apparaitre comme une réaction à ces deux constats. Trois parties le constituent : une réflexion théorique sur le genre de l'exposé, des propositions d'activités destinées aux élèves du dernier degré de l'enseignement primaire et des trois degrés de l'enseignement secondaire et, enfin, une proposition de programmation relative à l'exposé, qui couvre ces mêmes étapes de la scolarité.

La banque de graines du sol des forêts denses humides africaines a été très peu étudiée, alors qu’elle pourrait jouer un rôle déterminant dans les cycles sylvigénétiques naturels. Elle pourrait également être avantageusement utilisée dans les programmes de restauration, à l’instar de ce qui se fait sur d’autres continents. La présente synthèse bibliographique fait le point sur les connaissances actuelles relatives à la banque de graines du sol, en mettant l’accent sur le continent africain. Elle montre qu’une meilleure caractérisation de la banque de graines du sol des différentes communautés végétales constituerait une contribution notable pour la gestion durable des forêts tropicales d’Afrique.

Fossil pollen and charcoal fragments are preserved in lake sediments, in forest soils and in ancient human settlements, were they can be accompanied by artifacts. As such, vegetation history is remarkably well archived and sometimes closely linked to cultural history. Direct evidence for Central African vegetation history has been mainly derived from pollen analysis, while the charcoal archive remains hardly explored. However, analysis of charred wood remains has proven worthwhile for palaeovegetation reconstructions in temperate and arid regions. One of the main challenges for charcoal identification in tropical regions is species diversity. Therefore we developed and present a transparent charcoal identification protocol within an umbrella database of species names and metadata, compiled from the on-line database of wood-anatomical descriptions (InsideWood), the database of the world’s largest reference collection of Central African wood specimens (RMCA, Tervuren, Belgium) and inventory and indicator species lists. We applied the protocol on radiocarbon dated charcoal collections sampled in the Mayumbe forest (Bas-Congo, DRCongo), in human settlements along the Aruwimi and Lomami rivers (Province Orientale, DRCongo), along the Sangha river (Sangha department, Republic of the Congo) and in Pallisco logging concessions (East Province of Cameroon). First charcoal identification results are promising and sometimes seem to be taxonomically more precise than pollen identification. However, next to opportunities, we also present some pitfalls when exploring ancient charcoal archives. [less ▲]
