Short summary
We have calculated erosion caused by an extreme storm in the Atacama Desert. Erosion distribution depends on the ability of catchments to store sediments in stream networks between storms and generate debris flows during the storm. The order of magnitude of erosion is the same as the erosion rates calculated over the long term, so these storms have a relevant influence on the evolution of these arid fluvial systems.
