Abstract

Bedrock river profiles are often interpreted with the aid of slope-area analysis, but noisy topographic data make such interpretations challenging. The AA. present an alternative approach based on an integration of the steady-state form of the stream power equation. The main component of this approach is a transformation of the horizontal coordinate that converts a steady-state river profile into a straight line with a slope that is simply related to the ratio of the uplift rate to the erodibility. The transformed profiles, called chi plots, have other useful properties, including co-linearity of steady-state tributaries with their main stem and the ease of identifying transient erosional signals. They illustrate these applications with analyses of river profiles extracted from digital topographic datasets
