Here we acknowledge an omission and offer a perspective on the importance of domain size for the simple landscape evolution model that appears in our original manuscript. For completeness, the domain size should have been included in the nondimensionalization. However, it can be shown to be of little consequence in the region of the parameter space that we examined. Furthermore, we show that our choice of nondimensionalization (with landscape evolution process rates rather than domain size) allows for a clearer view of controls on intrinsic features of the results, including valley spacing and channel head contributing areas, which were the focus of our original analysis.
