| Sumario: | Wildfires affect soil properties, such as infiltration capacity. When precipitation exceeds infiltration capacity, water surplus occurs. This study aimed to determine water surpluses in the soils of the Bamba Hydric and Natural Reserve (BHNR) affected by rural fires in 2020. A vegetation cover map was developed through supervised classification. Infiltration capacity equations were applied based on land-cover classes and soil taxonomy, and then corrected using a slope map generated from a digital elevation model (DEM). Normalized burn ratio (NBR) index calculations determined that 5019.39 ha were affected (50.97 % of the total reserve area). The most affected land-cover classes were open forest and grassland, which represented 42.44 % and 37.33 % of the burned area, respectively. The water surplus percentages in the BHNR, following rural fires and considering recurrence times of five, ten, and twenty-five years, showed increases of 11.24 %, 23.63 %, and 26.87 %, respectively. Increasing percentages of burned areas and steeper slopes increase the water surplus percentages. Water surplus decreases with a higher proportion of bare soil. |
