Cover Story: In the Navalacruz wildfire, the loss of vegetation associated with the fire was responsible for a high rate of sedimentation in the rivers. The burned area affected up to 60 cultural heritage sites. We analyze the post-fire evolution based on a field survey of infiltration rates, hydrodynamic modeling, and channel morphological changes. The first post-fire rains caused the mobilization and transport of ashes, hydrophobicity in the soils and large transported sediments to rivers by subsequent low-magnitude storms. These trends are a consequence of a post-fire increase in flow rates for similar rainfall scenarios resulting in an increase in sediment transport capacities associated with this increase in flow rates. The combination of steep slopes with high severity and a deep regolith resulted in a series of cascading responses. View this paper
