Mean sediment residence time in barchan dunes

, 2014
International audienceWhen a barchan dune migrates, the sediment trapped on its lee side is later mobilized when exposed on the stoss side. Then sand grains may undergo many dune turnover cycles before their ejection along the horns, but the amount of ...
