Soil Erosion Monitoring in Quarry Restoration Using Drones

Mining is an essential activity that supports the provision of raw materials. However, extraction process mining has deep environmental impacts. For this reason, restoration actions are mandatory, and monitoring a key step in ensuring renaturalization affected areas. Erosion processes one main problems affect restored areas extractive activities due to frequently steep slopes difficulty revegetating technosols constructed using debris. This research aims develop method for determining soil losses water erosion mine-restored by Geographic Information Systems (GIS) Remote Sensing (RS) tools. study, images obtained Unmanned Aerial (UAS) open pit mine used, from which Digital Elevation Model (DEM) current state (0.10 m spatial resolution). With GIS techniques, ridges rills gullies generated detected, whereby estimation first DEM before erosive second after can be constructed. Each these DEMs evaluated individually order determine height differences estimate volumetric loss. At same time, results validated with derived official mapping agencies’ airborne Lidar data (1.00 resolution), yield consistent quantification despite difference resolution. In conclusion, high resolution drone facilitated detailed processes, obtaining vast inaccessible usually immeasurable traditional field altogether improving restoration.
