Short summary
The past flood activity was investigated using a sedimentological and geochemical analysis of surfaces sediments from a southeastern Tunisian catchment in order to trace the origin of sediments deposit in the El Bibane Lagoon. Aeolian, fluvial and marine source. This multi-proxy analysis on the BL12-10 core shows that finer material, a high content of clay and silt, and a high content of the elemental ratios Fe / Ca and Ti / Ca characterise the sedimentological signature of palaeo-flood levels.
