Hillslope erosion was\r\ncalculated using the revised universal soil loss equation (RUSLE) which estimates soil\r\nloss (t ha-1 yr-1) by runoff. Rainfall-runoff erosivity (R) factor (MJ mm ha-1 hr-1 yr-1) in\r\nRUSLE was estimated using a daily rainfall erosivity modelling for NSW and long-term\r\nrainfall records (Yang and Yu 2015). The soil erodibility (K) factor (t ha h ha-1 MJ-1 mm-1)\r\nwas estimated from digital soil mapping products and soil profile data (Yang et al 2017).\r\nSlope length and steepness (LS, unitless) factor was calculated, on catchment basis, from\r\nhydrologically corrected digital elevation model (SRTM DEM-H) based on comprehensive\r\nalgorithms considering cumulative overland flow length (Yang 2015). The time series\r\ngroundcover products (the latest version, V310) from Moderate Resolution Imaging\r\nSpectroradiometer (MODIS) were used to estimate groundcover and RUSLE cover and\r\nmanagement (C, unitless) factor (Yang 2014). Time-series hillslope erosion datasets and maps were produced on monthly and annual bases from 2000 to present. The state and trends of hillslope erosion\r\nacross New South Wales are summarised in Yang (2020). The relevant references are \r\nbelow: \r\n\r\n### Cover Erosion\r\nThis occurs when there is vegetation or ground cover, like grasses, shrubs or leaf litter, on the slope.  The cover helps protect the soil from direct raindrop impact, reduces the velocity of surface runoff, and increase infiltration.  As a result, erosion rates tend to be lower because the cover acts as a natural barrier that holds soil in place.\r\n\r\n### Bare Soil Erosion\r\nThis takes place on slopes with exposed soil, lacking any form of vegetation or cover. Bare soil is more vulnerable to erosion because there's nothing to cushion the impact of rainfall or slow down water flow.  The lack of cover results in higher runoff velocity, which intensifies erosion processes, leading to greater soil displacement, sediment transport and potentially faster degradation of the slope.\r\n\r\n1.
