Short summary
We present 2D morphodynamic simulations of hydraulics and sediment deposition patterns over an exposed bedrock anastomosed pavement. Alluvial barforms appear to be initiated through sediment deposition in bedrock topographic lows. It is likely that vegetation establishment in these depositional loci increases the cohesive strength of the deposited sediment and captures additional sediment and propagules, eventually leading to greatest thicknesses of alluvium positioned over the bedrock lows.
