Description :
The AA. illustrate the influence of initial conditions with examples drawn from two well-studied systems : the formation of ridge-and-valley topography through the coupled evolution of soil-mantled hillslopes and fluvial channels, and the emergence of cyclic steps in steep, sandy beds. In this section, they briefly describe the dynamics of these systems and the models used to conduct the numerical experiments. The results highlight the importance to consider the influence of initial conditions when comparing models with natural topography, estimating the uncertainty of model predictions, and studying how landscapes respond to disturbances.
