Mapping the spatio-temporal variability of hillslope erosion with the G2 model and GIS: A case-study of the South Australian agricultural zone

•The G2 model efficiently captured the spatial and temporal variability in erosion.•High-resolution rainfall data was essential to capture erosive events.•Severe erosion events were driven by low ground cover and extreme precipitation.•Identification of high erosion risk areas and timing to support land management.
