Topsoil field-saturated hydraulic conductivity, Kfs, is a parameter that controls the partition of rainfall between infiltration and runoff and is a key parameter in most distributed hydrological models. There is a mismatch between the scale of local in situ Kfs measurements and the scale at which the parameter is required in models for regional ma...

In the highlands of southern Colombia and northern Ecuador, soils developed on volcanic ash deposits have specific properties: high water retention, high hydraulic conductivity and high carbon (C) contents. The main role of the soils is to regulate the water available for the dense population living in the valleys. Soil properties and land use depe...

An updated procedure for a CTD-oxygen calibration along with new data processing was applied to recent hydrographic cruise data in the Coral Sea during the Cruise "BIFURCATION" in September 2012. After a brief introduction with the scientific context (section 1), we describe the contents and acquisition models of hydrological and chemical data that...

It is crucial to understand the adaptive mechanisms of woody plants facing periodic drought to assess their vulnerability to the increasing climate variability predicted in the Sahel. Guiera senegalensis J.F.Gmel is a semi-evergreen Combretaceae commonly found in Sahelian rangelands, fallows and crop fields because of its value as an agroforestry s...

Les barrières de sécurité passives reconstituées, des installations de stockage de déchets, sont conçues à l'aide de géomatériau bentonitique, sous forme d'un géosynthétique bentonitique (GSB), ou d'un sol traité. Ce travail présente les études expérimentales relatives aux comportements hydromécaniques et chimiques à long terme des géomatériaux d'é...

Description du sujet. Ce travail présente et analyse l'évolution de la conductivité hydraulique des surfaces cultivées et en jachère des formations pédologiques sablo-limoneuses couvrant les altérites du socle cristallin de l'Ouest du Niger. Le travail est mené en des emplacements choisis pour leur représentativité dans la zone sahélienne cultivée....

Because of technical difficulties in measuring soil properties at a large scale, little is known about the effect of soil properties on the spatial distribution of trees in grasslands. We were interested in the associations of soil properties with the phenomenon of tree encroachment, where trees increase in density at the expense of grasses. The sp...
