Why Do Fluvial Valleys Behave So Differently?
Source: AGU Advances Editors’ Highlights are summaries of recent papers by AGU’s journal editors. The shape of fluvial valleys results from the complex interaction between climate and the local environment. Our current knowledge suggests that river discharge and valley-wall lithology are the main controls on valley width. Yet, current models based on these observations fail […]
