Description :
Within the context of the proposed method a soil-erosion model is integrated within a GIS and remote sensing and digital cartographic data are used for estimating the model parameters before and after the passage of the fire. The model incorporates the effects of fire on the parameters that control erosion using remotely sensed estimates of the characteristics of the fire, such as the temperature and the extent. The method was implemented in 4 regions in Greece where severe wildfires took place during the summer of 1998. It is showed significant changes in runoff and erosion patterns as a result of the passage of the fire and a notable increase in the spatial variability of post-fire erosion rates.
