 This study uses structure for motion, SFM, technique to monitor soil loss, gully head retreat, and plunge pool development in southern Morocco using high-resolution 3D imagery. Due to the impractical use of terrestrial IDAR in difficult-to-access gully systems, SFM is a promising tool for analyzing and monitoring these processes. Objects with known dimensions were placed around the gully scenes for scaling purposes and free-scaling with objects was compared to terrestrial laser scanner, TLS, data in a field laboratory in Germany. Results showed discrepancies of 5.6% in volume difference for erosion and 1.7% for accumulation between SFM and TLS. Soil loss varied between 0.58 T in an 18.65 square meters narrowly stretched gully incision and 5.25 T for 17.45 square meters in a widely expanded head cut area following two heavy rain events. Different techniques of data preparation were applied and the advantages of SFM for soil erosion monitoring under complex surface conditions were demonstrated.
