This study characterised gully morphology and activity, identified the factors related to gully volume, and estimated the topographic thresholds for sub-catchments subject to woody encroachment. Firstly, relationships between gully volume, activity, topography, vegetation cover and road infrastructure were explored. Secondly, site characteristics of 32 sub-catchments with and without gullies were compared. Finally, the topographic thresholds for unstable and stable sub-catchments with and without gullies, respectively, were estimated using a slope – drainage area relationship. The mean topographic threshold for gully development provided insights into the drainage area and slope conditions needed for gully development. Gully erosion in the study area is most likely the result of interactions among topography, vegetation and human-made structures (roads) in space and time
