Hillslope erosion measurement-a simple approach to a complex process

The measurement of hillslope erosion can be a difficult, costly and time-consuming activity. Many techniques are available, ranging from using environmental tracers, to LiDAR. Erosion measurements using erosion pins are assessed and compared with regional scale erosion data, hillslope data obtained using Cs-137 and erosion modelling results. The pins produced erosion rates which are within the range determined using Cs-137 and model data but above that of regional denudation rates. Our findings demonstrate that inexpensive erosion pins can provide reliable data on hillslope erosion. (c) 2015 Commonwealth of Australia. Hydrological Processes (c) 2015 John Wiley & Sons Ltd.
