Overland flow generation processes, erosion yields and nutrientloss under fires with different intensities – Lessons learned fromanalysis at different scales

摘要

In addition to the incineration of vegetation and litter layer, fires are also responsiblernfor the formation of a hydrophobic layer with different spatial distribution following differentrnburning intensities. This spatial distribution patterns have an enormous influence on soil wettingrnpatterns, and on hydrological processes at different scales, which drive the erosion yields and nutrientrnloss. This study attempts to isolate the impact of hydrophobicity severity and spatial distributionrnon soil and slope water processes, soil erosion and nutrient loss by comparing areasrnburned by different intensity fires.
