Abstract
Prediction of sediment transport in concentrated overland flow remains a fundamental challenge in soil erosion assessment. Sediment transport is often modelled as a non‐linear function of shear stress. These relations are mostly derived from river channels or flume experiments. Here, new data of active incisions that occurred as a response to a single runoff event is presented. This allowed to complement and revisit a field‐based sediment transport‐shear stress equation. The results demonstrate the general applicability of the proposed relation for predicting sediment transport in linear incisions, ranging from rills to gullies, in field conditions. These findings have important implications for erosion modelling. Copyright © 2009 John Wiley & Sons, Ltd.
