Abstract
We report results from an empirical study of the anisotropic structure of e roding landscapes. By constructing a novel correlation function, we show qu antitatively that small-scale channel-like features of landscapes are coupl ed to the large-scale structure of drainage basins. We show additionally th at this two-scale interaction is scale-dependent. The latter observation su ggests that a commonly applied effective equation for erosive transport may itself depend on scale.
