In Tunisia, lunettes are characteristic in the area of Tunis and in the Central-Eastern steppes, but we notice they disappeared quickly in the Sahara margin. All of them were built during Holocene times, but during different periods according with bioclimatic requirements and hydrologie regimes of the desert play as. The particularities of their distribution, the peculiarity of their genetic processes and observation about similar active phenomena are proofs that these inherited landforms are related to moderately-arid environments. So, they point out the ability for the wind to have a main rôle in the shaping of their relief.En Tunisie, les lunettes caractérisent la région tunisoise et les steppes du Centre-Est, alors qu'on note leur dispa...
