Height data for the surface profiles of the (a) original surface prior to evolution, and surface after 60 h of evolution using (b) the linear evolution equation and (c) nonlinear evolution equation at θ=45°. The surface height is normalized to the maximum height, where the peaks are shown by the red regions while the troughs are shown as blue. The x- and y-axes are expressed in [m] to show the feature size. The evolution parameters are as shown in Table 1. Both evolution regimes produce dots-on-ripples patterns, with contrasting characteristics
