The Algerian Saharan mountains, northern border of the Sahara desert, participate greatly to the understanding of the desertification processes and play a fundamental role in the research of the sand-transfers flux on both sides of the Atlasic belt. This paper is based on a detailed map and concern the South-East part of Hodna-basin, the M'Doukal region, where the interaction relief-sand transfers are expressed here. The main results of the study confirm the existence of the «barrier-relief» which stops the sand-transfers from the Hodna region and of the «corridor relief» which facilitates sands transfers. Through this large transatlasic flux, the hydro-aeolian depressions seem to maintain the permanence of the phenomenon.Les montagnes de l...
