The oasis landscapes of the Nefzaoua (southern Tunisia) have been structured at least since antiquity around artesian springs. They emerged in a circular geomorphologic formation that could reach several hundred meters in diameter and a few tens of meters in height called mound. These mounds of springs consist of a ring of sedimentary material redistributed by the artesian waters and especially of aeolian material trapped by the vegetation growing around the springs.
