Abstract

This paper applies a landscape evolution model (LEM) for the first time at time and space scales where soil erosion models have largely been used. It tests the ability of the LEM (the CAESAR model) to predict soil erosion on a 30 m experimental plot on a trial rehabilitated landform in the Northern Territory, Australia. It then continues to discuss the synergies and differences between soil erosion and LEMs. The results demonstrate that once calibrated for the site hydrology, predicted suspended sediment and bedload yields from CAESAR show a close correspondence in both volume and timing of field measured data. The model also predicts, at decadal scales, sediment loads close to that of field measured data. Findings indicate that the small-scale drainage network that forms within these erosion plots is an important control on the timing and magnitude of sediment delivery
