This study investigates the shifts in fan‐river coupling during two major consecutive debris flow events (March 2015 and May 2017) on tributary‐junction alluvial fans situated in the Atacama Desert in the Andes. Studying the geomorphological consequences of debris flow events in these fans provides a unique opportunity to understand the mechanisms of fan formation and destruction in arid landscapes. To do so, we integrate repeated high‐resolution topography of two end‐member fans representative of fans built in confined fluvial settings in the Andes, along with detailed geomorphological and sedimentological mapping.
