Geomorphology: Landscape texture set to scale.

The article examines the ridge-valley spacing. According to theory, valley spacing in low-relief, soil-mantled landscape is set by the ratio between hillslope transport intensity and channel incision intensity. It cites that one study shows that the wide variation in ridge-valley spacing can be explained by a simple model of this competition in a certain class of landscape. Moreover, it points out that this study provides a successful test of theory, in which their data contain further hints about the underlying controls exercised by the substrate and climate.
