Abstract
Anthropogenic activities and climate change have accelerated soil erosion in the Mediterranean. In the region, erosion rates are further exacerbated due to frequent wildfires and flash floods. Soil bioengineering works and nature-based solutions need to be placed in targeted areas to provide the greatest erosion control in the burnt areas. The purpose of this study was to provide a targeted approach by utilizing spatial software along with field measurements to place optimally soil erosion prevention works. Specifically, the Gavrilovic soil erosion equation was implemented within the Geographical Information System (GIS) to estimate the areas of greatest erosion potential. The study area was Prinos Watershed of Thasos Island in Greece that was burnt in the summer of 2017. To run the soil erosion equation in GIS, different layers of data were collected or developed. Visual field measurements were taken to estimate the erosion potential factor. The results indicated the areas with the greatest soil erosion and allowed to pinpoint the location for the soil bioengineering works. The recommended works were wooden dams and log erosion barriers. This method could be used by the Greek Forest Service to promote the sustainable restoration of burnt areas.
