Randomized trial evaluates erosion dynamics in restored mining slopes, suggesting effective monitoring methods.

The study aims to evaluate erosion dynamics on restored mining slopes using advanced monitoring techniques.
Conducted research at the Lázaro quarry, Tarragona, Spain using UAS equipped with a multispectral camera.
Produced Digital Elevation Models (DEMs) and compared them with historical LiDAR data.
Applied statistical assessments including error metrics and spatial autocorrelation to analyze erosion and deposition.
DEMp provides the most reliable volume estimates and best preserves pre-erosion morphology.
DEMf smooths surface detail less effectively than DEMp, impacting erosion representation.
DEMl offers an overview but has lower spatial resolution compared to the other models.

Moncada et al. (2026) studied this question.
