Bedforms and associated bedforms in the field. (A) 3D Current Ripples; (B) 3D Asymmetrical Ripples; (C) 2/2.5 D Symmetrical ripples; (D) 2D Small Symmetrical Dunes in the center of the residual channel are associated with 3D Current Ripples (on left) and Upper Stage Plane Bed (on the right); (E) 2D symmetrical Dunes associated with 3D Asymmetrical Ripples and Upper Stage Plane is also present on top right corner (white bar in the red circle in 20 cm); (F) 3D Symmetrical Dunes associated to 2/2.5 D Symmetrical ripples in the troughs (person for scale is 1.75 m high); (G) Association of bedforms in a runnel at the junction of two ridges, 3D Symmetrical Dunes are covered by 2/2.5 D Symmetrical ripples, 3D Current Ripples or 3D Asymmetrical Ripples. Note that 3D CR evolve as delta-like sediment accumulation within the trough (doted white line); (H) 3D Symmetrical Dunes, locally the hummocks are flattened (-f) and so replaced by Upper Stage Plane Bed. 2/2.5 D Symmetrical ripples are preserved in the troughs (white bar in the red circle in 20 cm).
