Abstract:For centuries, land in the North East of Brazil has been overexploited, which has brought a large area to a high degradation level, vulnerable to erosion. Ephemeral gullies emerge with increasing frequency. Among the potential impacts of gully erosion, there is the change in connectivity patterns, which might influence the sediment delivery ratio and therefore, the rates of sediment transfer from the hillslopes into the lower parts of the catchment area. The purpose of this research is to point out how gully erosion changes sediment connectivity patterns in a small-scale catchment area in the Brazilian semiarid region. This change can enhance rates of soil losses, river and reservoir silting and pollutant transfer, among others.
