Hazardous hydrological events cause soil erosion and it is essential to anticipate the potential environmental impacts of prevail-
ing erosion processes that occur at different time-scales. Here, we present the modelling of net soil erosion rates for the Bradano
River Basin (southern Italy), based on rainfall erosivity, surface overland flow and transport sub-models. A semi-empirical
framework was developed, upscaling point rainfall values based on the Foster-Thornes approach in order to give an insight into
monthly and annual soil losses over the period 1950–1958 and 1961 (calibration) and over a longer time-frame (1950–2020:
reconstruction). In the 2765-km2 study area, ~ 68% of the sediment mobilized within the basin reached the basin outlet (mean
value for 1950–2020: ~ 366 Mg km−2 yr−1
). A moderate declining trend in net erosion rates was observed after the 1980s, con-
current with the contraction of cropland in favour of natural vegetation and river channelization. Our results suggest that the
parsimonious principle used here seems sufficiently robust to be suitable for applications in other Mediterranean landscapes.
