133Campforts, BenjaminHyLands model run showing a period of intense landsliding over 100 years on a steady state topography. The upper left subplots show the landslide activity. The location of landslides is indicated with black diamonds. The colors represent the square root of the landslide erosion (-) and deposition (+) during the presented time step. The upper right subplots show the evolution of of sediment thickness (H) through time. On both subplots, the blue line represents the location of the river, plotted in the lower subplots. These lower subplots show the topographic and bedrock elevation (red and black line respectively) as well as the volume occupied by sediments (orange shaded area) and water (the blue shaded area). Note that, during landsliding, both pure landslide dams arise as well as irregularities in the bedrock profile (the grey bumps). The latter originate from the river being redirected after landsliding forming epigenetic gorges.

106Campforts, BenjaminHyLands model run showing evolution of the landscape to steady state.The upper left subplots show the evolution of topography through time. The upper right subplots show the evolution of of sediment thickness(H) through time. On both subplots, the blue line represents the location of the river, plotted in the lower subplots. These lower subplots show the topographic and bedrock elevation (red and black line respectively). The difference between the topographic elevation and the elevation of the bedrock represents the sediment thickness. With respect to total elevation, sediment thickness is small, which is why sediment thickness (orange line) is also plotted against a separate right-hand y-axis. The gray shaded area represents bedrock underlying the river profile.

123Campforts, BenjaminReestablishment of the landscape to steady state. Bedrock bumps created by landslide-induced drainage redirection are eroded and the channel re-attains its smoothly concave-up, steady-state configuration. The upper left subplots show the evolution of topography through time. The upper right subplots show the evolution of of sediment thickness(H) through time. On both subplots, the blue line represents the location of the river, plotted in the lower subplots. These lower subplots show the topographic and bedrock elevation (red and black line respectively). The difference between the topographic elevation and the elevation of the bedrock represents the sediment thickness. With respect to total elevation, sediment thickness is small, which is why sediment thickness (orange line) is also plotted against a separate right-hand y-axis. The gray shaded area represents bedrock underlying the river profile.
