Commentary on a “Conceptual model for complex river responses using an expanded Lane diagram by David Dust and Ellen Wohl”, Geomorphology, Volume 139–140, March 2012, Pages 109–121.

Abstract: This paper presents a revision of a river-flow response model by Dust and Wohl (2012). In particular, serious confusion of the relationship between sediment transport capacity and width-to-depth ratio is clarified. As a consequence, we propose a reasonable qualitative model for understanding the complexity of river responses as illustrated in an appropriately modified form of the Lane diagram, which identifies the equilibrium condition based on the balance between channel aggradation and degradation.
