dc.description.abstract | Ash thickness is a key variable in the protection of soil against erosion agents after
planned and unplanned fires. Thicker ash provides better protection against raindrop
impact and reduces the runoff response by retaining water and promoting water infiltra5 tion although little is known about the distribution and the evolution of the ash layer after
the fires. Ash thickness measurements were conducted along two transects (flat and
sloping areas) following a a grid experimental design. Both transects extended from
the burned area into an adjacent unburned area. We analysed ash thickness evolution
according to time and fire severity. In order to interpolate data with accuracy and iden10 tify the techniques with the least bias, several interpolation methods were tested in the
grid plot. Overall, the fire had a low severity. The fire significantly reduced the ground
cover, especially on sloping areas owing to the higher fire severity and/or less biomass
previous to the fire. Ash thickness depends on fire severity and is thin where fire severity was higher and thicker in lower fire severity sites. The ash thickness decreased
15 with time after the fire. Between 4 and 16 days after the fire, ash was transported by
wind. The major reduction took place between 16 and 34 days after the fire as a result of rainfall, and was more efficient where fire severity was higher. Between 34 and
45 days after the fire no significant differences in ash thickness were identified among
ash colours and only traces of the ash layer remained. The omni-directional experimen20 tal variograms shown that variable structure did not change importantly with the time,
however, the most accurate interpolation methods were different highlighting the slight
different patterns of ash thickness distribution with the time. The ash spatial variability
increased with the time, particularly on the slope, as a result of water erosion. | es |
