Sediment transport in forested head water catchments – Calibration and validation of a soil erosion and landscape evolution model

摘要

Highlights?A computer based landscape evolution model is calibrated for a forested environment.?The model (SIBERIA) reliably predicts field measured sediment transport rates.?Also, pattern of erosion and deposition is matched with field observation.?The model offers huge potential for quantifying sediment transport in such environments.AbstractSediment transport and soil erosion can be determined by a variety of field and modelling approaches. Computer based soil erosion and landscape evolution models (LEMs) offer the potential to be reliable assessment and prediction tools. An advantage of such models is that they provide both erosion and deposition patterns as well as total catchment sediment output. However, before use, like all models they require calibration and validation. In recent years LEMs have been used for a variety of both natural and disturbed landscape assessment. However, these models have not been
