  abstract = {{T}he aim of this study is the reconstitution of the recent morpho-sedimentary evolution of the {M}edjerda {R}iver delta. {W}e examine the spatio-temporal evolution of the {M}edjerda shoreline between 1936 and 2016 using satellite images, complemented by sedimentological and geochemical analyses and (210){P}bex and (137) {C}s radiometric data. {T}he general tendency of the shoreline evolution shows an increasing progradation (300 +/- 12 m) between 1936 and 2016. {Y}et the mesoscale {N}et {S}horeline {M}ovement position ({NSM}) and the {E}nd {P}oint {R}ate ({EPR}) reveal an erosion pattern estimated to be -20 m +/- 0.15 m/yr during the period 1988-1999. {T}he sedimentological analyses reveal four main lithostratigraphic units. {T}he fine sand substratum layer ({M}d = 0.08 mm) decreases toward clay and silt facies ({M}d < 0.063 mm), rich in continental plant debris. {T}he geochemical results reveal gradual incoming of the terrigenous component instead of marine deposits. {T}he {C}s-137/(210) {P}bex radiometric dating confirms the functioning of the new river flow by the 1950s with the highest sedimentation rate being 3.3 cm/yr. {O}ur results show that the {S}idi-{S}alem dam impoundment (1981) led to a dramatic reduction of sediment discharge, a decrease of the grain size with nearly no more sand reaching the coast, and the shoreline retreat.},
