Abstract
The use of
photogrammetry based on UAVs allows to survey long distances of riverbanks with
a resolution capable of identifying detailed bank erosion features and quantifying
retreat rates with an accuracy of centimetres. The identification of these
features would be missed in slower and more expensive GPS profiling. Moreover, moving
terrestrial laser scanning would require significant greater times and costs
for comparable results.
