Abstract

A large panel of instruments was deployed in the Eastern English Channel tomeasure the evolution of bedload fluxes during a tidal cycle for two different sites. The firstone was characterized by a sandy bed with a low dispersion in size while the other studysite implied graded sediments with grain sizes ranging from fine sands to granules. Thein situ results obtained were compared with predictions of total bedload fluxes by classicalmodels.Agoodagreementwasfoundforhomogeneoussedimentswiththeseformulas.Inthecase of size heterogeneous sediments, a fractionwise approach, involving a hiding-exposurecoefficientandahindrancefactor,providedbetterpredictionsofbedloadfluxes,butstillsomediscrepancies were noticed. Present results revealed that the consideration of particle shapein formulas through the circularity index enhanced the estimations of bedload transport rates.A new adjustment of Wu et al.’s (J Hydraul Res 38:427–434, 2000) formula was proposed and a very good agreement was obtained between the measured and predicted values.

<div type="abstract" xml:lang="en">A large panel of instruments was deployed in the Eastern English Channel tomeasure the evolution of bedload fluxes during a tidal cycle for two different sites. The firstone was characterized by a sandy bed with a low dispersion in size while the other studysite implied graded sediments with grain sizes ranging from fine sands to granules. Thein situ results obtained were compared with predictions of total bedload fluxes by classicalmodels.Agoodagreementwasfoundforhomogeneoussedimentswiththeseformulas.Inthecase of size heterogeneous sediments, a fractionwise approach, involving a hiding-exposurecoefficientandahindrancefactor,providedbetterpredictionsofbedloadfluxes,butstillsomediscrepancies were noticed. Present results revealed that the consideration of particle shapein formulas through the circularity index enhanced the estimations of bedload transport rates.A new adjustment of Wu et al.’s (J Hydraul Res 38:427–434, 2000) formula was proposed and a very good agreement was obtained between the measured and predicted values.</div>
