Clayton Sorensen co-authors an analysis of climate influence on erosional processes and topographic evolution.


Climate has long been thought to control a landscape’s evolution. However, studies investigating the connection between climate and topography indicate inconsistent conclusions, and either link or disjoin climate and landscape processes over various landscapes. To test climate’s influence on topographic form, a landscape evolution numerical model was calibrated with 30-year reanalysis climate data over the Andes of South America to predict latitudinal trends in topography subject only to fluvial erosion and hillslope processes. A common storm metric, mean annual precipitation, is tested against ‘storm statistics’ to understand the implications in using various storm metrics in linking climate and erosional processes.
