Kurzfassung/Abstract

This study focuses on the quantification and analysis
of geomorphic processes on the barely vegetated slopes of
a recultivated iron ore mine on the Italian island of Elba using
photographs from terrestrial laser scanning (TLS) and digital
photogrammetry by an unmanned aerial vehicle (UAV) over
a period of 5 1/2 years. Beside this, the study tried to work
out the potential and the limitations of both methods to detect
surface changes by geomorphic process dynamics within a
natural environment. Both UAV and TLS show the pattern of
the erosion and accumulation processes on the investigated
slope quite well, but the calculated amounts differ clearly between
the methods. The reasons for these differences could
be found in the different accuracies (variable level of detections)
of the methods and the different viewing geometries.
Both effects have an impact on the detectable process dynamics
over different timescales on the slope and their calculated
amounts, which in both cases can lead to an underestimation
of erosion and accumulation by fluvial processes.
