Study region: Houay Xon catchment in northern Laos.Study focus: Because agricultural headwater catchments of SE Asia are prone to erosion anddeliver a significant proportion of the total suspended sediment supply to major rivers andfloodplains, the potential sources of sediments and their dynamics were studied for twosuccessive storm flow events in...

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...
Extreme hydrological events
During a flood event over a karst watershed, the connections between surface and ground waters appear to be complex ones. The karst may attenuate surface floods by absorbing water or contribute to the surface flood by direct contribution of karst waters in the rivers (perennial and overflowing springs) and by diffuse resurgence along the hillslopes...
