Testing simple approaches to map sediment mobilisation hotspots after wildfires

Background The models currently used to predict post-fire soil erosion risks are limited by high data demands and long computation times. An alternative is map the potential hydrological sediment connectivity using indices express general properties of burnt landscape.Aims In this study, we aimed answer question: Do these tools identify mobilisation hotspots?Methods To achieve this, assessed spatial variability distribution location hotspots Index Connectivity, Revised Universal Soil Loss Equation Sediment Export, compared it with simulation results a more complex Landscape Evolution Model (LAPSUS model). Additionally, evaluated statistical measures association between four tools.Key three tested in study suitable for identifying hotspots, where rates above 95th percentile, differences their performance small.Conclusions indicate that help locate extreme locations recently areas.Implications These can be considered water contamination risk management, especially fast prioritisation areas needing emergency intervention.
