Abstract

The AA. investigate how medium-term gully-development data differ from short-term data, and which factors influence their spatial and temporal variability at 9 selected actively retreating bank gullies situated in 4 Spanish basin landscapes. Results 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 on runoff production and connectivity play a dominant role in these study areas, both for short-term variability and medium-term difference in gully development. The study proves the value of capturing spatially continuous, high-resolution three-dimensional data using small-format aerial photography for detailed gully monitoring. Results confirm that short-term data are not representative of longer-term gully development and demonstrate the necessity for medium- to long-term monitoring
