Supplementary material to "On the scaling of the instability of a flat sediment bed with respect to ripple-like patterns"

This resource provides supplementary material to the publication "On the scaling of the instability of a flat sediment bed with respect to ripple-like patterns" (Journal of Fluid Mechanics, 2020). In particular, we present time resolved visualizations of the sediment bed evolution for several of the studied cases: - H6D052: Lx/H=6, Lx/D= 52, H/D= 7.9, Re=3011, Ga=104.2, Shields=0.14 - H6D077: Lx/H=6, Lx/D= 77, H/D=12.3, Re=3011, Ga= 56.7, Shields=0.17 - H6D154: Lx/H=6, Lx/D=154, H/D=25.5, Re=3011, Ga= 28.4, Shields=0.18
