Regularity of transportation for cohesive bank-collapsed materials

Guosheng Duan and Haifei Liu

Abstract. The transportation of bank-collapsed materials is a key issue among river evolution processes. In this study, a series of flume experiments were conducted to monitor riverbank collapse processes and to explore the regularity of transportation for cohesive collapsed materials. The collapsed materials, both the bed and suspended loads, that transformed from collapsed materials were intensively evaluated under experimental conditions. The results showed that the collapsed materials contributed to 12~20 % sedimentation in situ, 8~14 % suspended loads and 70~80 % bed loads. In addition, the bed load motion efficiency coefficient (eb), suspended load motion efficiency coefficient (es) and sediment carrying capacity factor (U3/gRω) were introduced to describe the transportation of collapsed materials in terms of energy dissipation. This research provides theoretical and practical benefits for predicting channel evolution processes.

Short summary
As riverbank collapse and bank-collapsed materials transportation are important contributing factors among river evolution and geomorphic processes, a series of flume experiments were conducted to quantify transformation for cohesive bank-collapsed materials. transportation in terms of energy dissipation. The results made a valuable addition to current state of the art in understanding and characterising sediment transport.
