Field Evidence for the Initiation of Isolated Aeolian Sand Patches
WebEarly‐stage aeolian bedforms, or protodunes, are elemental in the continuum of dune development and act as essential precursors to mature dunes. Despite this, we know very little about the processes and feedback mechanisms that shape these nascent bedforms. Whilst theory and conceptual models have offered some explanation for protodune … WebApr 21, 2024 · We report a landscape-scale experiment with controlled initial and boundary conditions to reveal incipient dune growth under natural action of wind.
