Soil erodibility was studied in El Hammam catchment, Algeria, to see how easily soil can be eroded by water. 51 soil samples were collected and analyzed. The erodibility factor ranged from 0.16 to 0.66, showing significant variation. Erodibility was negatively correlated with clay, organic matter, and permeability, but positively correlated with silt, sand, and soil structure. A map was created using kriging to show the spatial distribution of erodibility, with the study area classified as highly erodible and ecologically vulnerable.
