To help constrain the long-term pattern and rate of soil mixing and transport in forests, the AA. analyzed the distribution of tephra grains in soil along a hillslope transect in the Blue Mountains. Deposited within a loess mantle, tephra associated with the eruption of Mt Mazama serves as a marker bed for estimating erosion and transport rates. The main components of the study include using topography and the distribution of tephra to test and calibrate a soil transport model for a forested ecosystem. The results are important for interpreting how vegetation affects rates of sediment production and the evolution of topography over geomorphic timescales
