Analysis of spatial variability of river network morphology, flow and potential energy

Abstract

Horton-type laws describe the downstream change in link morphological and topological characteristics. Accordingly, surrogates to the traditional stream length and area ratios are provided by the link number ratio, and the total link number ratio, respectively. The opposite statistical behaviour of stream and link length, as being dependent and independent variables, respectively, is found to be reversed in the case of link and stream heights. This property leads to an identical trend in the spatial variability of slope in both cases. Results show an increasing structure departure from simple-scaling for the n-th order moments. -from Authors
