A total load formula for the nearshore
Une formule de transport total pour le côtier
Résumé
A total load sediment transport formula based on recent studies on the bed load and suspended load transport for the nearshore is presented. Phase-lag in the sheet-flow layer or due to ripples, as well as acceleration effects, is included in the formula. A sensitivity analysis is performed to better qualify and quantify the current-related and wave-related sediment transport. It appeared that the prediction of the ripple characteristics is fundamental for a proper estimation of the suspended load in the direction of the waves. For the longshore sediment transport where the current-related total load prevails, the formulas are not as sensitive to ripples.
