Abstract(s)
Soil erosion has been causing an imbalance in nature and the environment. It is mainly
caused naturally but is also due to human interventions leading to desertification and possible
contamination. Therefore, engineering, geography, and cartography have been allies in applying
erosion models to predict, address, and remediate the impacts. Therefore, the Revised Universal
Soil Loss Equation (RUSLE) and Soil and Water Assessment Tool (SWAT) linked to Geographic
Information Systems (GISs) could boost decision making as tools to mitigate issues. This study
applies the RUSLE and SWAT models from a geotechnical point of view to analyze a sub-watershed
at Idanha-a-Nova (Portugal) over 4 years, showing a predominant erosion risk class with losses
lower than 5 t.ha−1.year−1 (60 to 86%), characterized as very low risk. The modeling permitted
the development of soils erosion susceptibility charts, in addition to material availability and the
suitability for construction areas, exposing a replicable methodology that could contribute to minimizing
environmental impacts while encouraging a more intelligent use of the land towards a greener
exploration.
