Slope Correction for Calculation of Bedload Sediment Transport Rates in Steep Channels
Publication: Journal of Hydraulic Engineering
Volume 140, Issue 6
Abstract
Classical theories developed for investigating bedload sediment transport are applicable largely for channel beds of a gentle slope. Examples are the well-known Shields diagram for the evaluation of the critical condition for initial sediment motion and the classical bedload transport formulas derived with deterministic or probabilistic approaches. How to apply the existing bedload formulas for steep channels remains challenging. In this study, a simple procedure is proposed for correcting slope effects so that the existing bedload formulas can be extended for steep channels. To verify the proposed correction factor, two representative bedload formulas are modified and checked against published data of sediment transport rates that were significantly affected by steep slopes.
