This study aims to determine whether increasing soil salinity levels promote higher rates of mnoff induced erosion. Rainfall simulation experiments, with an average intensity of 75 mm h- I , were conducted on eight 1-m2 runoff plots in central New South Wales, Australia. A cross-design method was adopted using three soil salinity levels (low, medium and high) and two vegetation covers «10% and >30%). Multiple regression analyses reveal that the sediment concentration of runoff is positively related to soil salinity levels and negatively related to vegetatIon cover (R- = 0.688; p > F = 0.048), suggesting a causal link between soil salinity and sediment mobilization. The results of this study will provide useful information to land managers seeking to redress salinity issues in terrestriaI and aquatic ecosystems.
