This study investigates how medium-term gully-development data differ from short-term data, and which factors are responsible for their spatial and temporal variability. Eight actively retreating bank gullies situated in Spanish basin landscapes were monitored for up to 11 years with high-resolution aerial photographs using unmanned remote-controlled platforms. The results of planimetric and volumetric change analysis using GIS and photogrammetry systems show a high variability of annual gully retreat rates both between gullies and between observation periods. The varying influences of land use and human activities with their positive or negative effects on runoff production and connectivity appears to play the most important role in these study areas, both for short-term variability and medium-term difference in gully development. The study demonstrates the importance of capturing spatially continuous, high-resolution three-dimensional data for detailed gully monitoring. It also confirms that short-term data are not representative of longer-term gully development, but they are still required to understand the processes - particularly human activity at varying time scales - causing gully-erosion variability.
