Infrequent, large-magnitude debris flows are important agents of landscape change.

The article discusses the impact of large-magnitude sediment flows on the shape of landscapes. It references the study "Exhumation by Debris Flows in the 2013 Colorado Front Range Storm" by S. W. Anderson et al. published within the issue. It also compares the results of the study with other studies that compared net sediment transport from large debris-flow events and long-term erosion rates.
