International audienceGully morphology (often summarized as comprising an alcove, channel and debris apron) is one of the key elements used to support the argument for liquid water in the recent past on Mars. Nevertheless, the processes that create different gully morphologies, both on Mars and on Earth, are not fully understood. One of the puzzling morphologic attributes of martian dune gullies is their apparent lack of an apron, or terminal deposit, which has caused debate about their formation process. Several physical processes could explain the formation of these gullies (e.g. runoff, debris flows, granular flows, sliding blocks falling downslope). In this work, we focus on the role of liquid in the substrate as well as in the flow and...
