We inquire into the morphodynamics of barchans under seasonal flows. For that, we carried out grain-scale numerical computations of a subaqueous barchan exposed to two-directional flows, and we varied the angle and frequency of oscillations. We show

Three dimensional dunes of crescentic shape, called barchans, are commonly found on Earth and other planetary environments. In the great majority of cases, barchans are organized in large fields in which corridors of size-selected barchans are observ

IntroductionWind erosion and the formation of sand dunes are common phenomena in many arid regions around the world. More than 100 types of sand dunes have been classified by geomorphologists based on shape and size criteria (Lancaster, 1995). One of

We investigate experimentally the short-range interactions occurring between two subaqueous barchans. The experiments were conducted in a water channel of transparent material where controlled grains were poured inside, and a camera placed on the top

The sand dunes of the study area are located downstream of Routack watershed, 40 km west of Saravan city (Baluchestan province, Iran) and in the northern margin of the agricultural lands of the region. Wind velocity data (direction and speed) of Sara
