To determine the impact of vegetative cover and slope on runoff, erosion and water quality, a field study was commenced in 1993 at 3 open-cut coal mine sites in the Bowen Basin. Field plots of 0.1 ha with slope gradients of 10, 20 and 30%, along with catchments of 0.1 ha, were used to measure runoff, sediment loss and water quality from rehabilitated land. Pasture and tree treatments were imposed on soil and spoil material, while 2 soil and spoil plots were left bare as the control for the study.
