Un lac d'eau douce au coeur du Sahel / Atlas du lac Tchad
Les principaux apports en eau sont constitués par les rivières qui alimentent le lac et par les précipitations qui tombent directement sur celui-ci. Les teneurs en éléments dissous de ces apports dépendent de la nature et de l'histoire géologique du bassin versant ainsi que de sa position géographique vis-à-vis des océans. Les flux sortants dépende...

36Cl measurements in groundwaters of the deep confined aquifer of the Lake Chad Basin (LCB) were performed in order to constrain groundwater geochemical ages and residence times. Twenty-seven wells were sampled in Nigeria, Niger and Chad in the southern parts of the large (700 000 km2) multilayered aquifer of the LCB. 36Cl/Cl values range between 1...
Influence of inherited paleotopography and water level rise on the sedimentary infill of Lake Ossa (S Cameroon) inferred...
Lacustrine records hold considerable archives providing access to valuable information. However, to decode this information it is necessary to know how the lake in question and its catchment area function. In this study we propose to highlight the different factors that govern sedimentation by studying different core samples covering the Holocene t...

Les sols
Les sols sont le support de nos activités agricoles et sylvicoles et les garants de notre sécurité alimentaire. Ils assurent un grand nombre de services écosystémiques qui sont au coeur de grands enjeux planétaires. Pourtant ils restent encore largement méconnus, en particulier au niveau mondial. Les programmes du Groupement d’intérêt scientifique ...
Impact of high-pH fluid circulation on long term hydromechanical behaviour and microstructure of compacted clay from the...
Published in Applied Clay Science
•Alkaline water circulation reduced the swelling ability of compacted clay.•Extended circulation led to an increase of friction angle.•Alteration of behaviour could be related to the neoformation of illite.•Alkaline water circulation alters the sealing characteristics of compacted clay.
