Fire influences surface processes on a multitude of spatial and temporal scales—from altering soil characteristics during a single wildfire to affecting global erosion rates across millennia. As wildfire activity expands and rainfall intensifies under a changing climate, understanding how surface processes respond to fire on short timescales (e.g., flash floods and debris flows) and longer timescales (e.g., shifts in evapotranspiration, runoff, and baseflow) will be critical to forecast postfire disturbances and develop mitigation strategies to assist communities recovering from wildfire. This session aims to unite a diverse group of scientists who share a common interest in topics relevant to wildfire impacts on surface processes. We invite studies that advance understanding of postfire geomorphic or hydrologic functioning, with implications for natural hazards, resource management, or landscape evolution.
