Severe wildfires in NW Spain lead to increased soil erosion. Two erosion prediction models, RUSLE and Disturbed WEPP, were tested on 44 field plots. Both models underestimated soil loss after the fire. RUSLE's accuracy was low, even with adjustments for soil organic matter. Neither model is effective for predicting soil erosion in the first year after a wildfire in NW Spain. Soil burn severity should be a key factor in post-fire erosion modeling.
