Abstract

Barbaro, G.; Foti, G.; Sicilia, L., and Malara, G., 2014. A formula for the calculation of the longshore sediment transport including spectral effects.

The objective of this paper is to propose an expression for the calculation of the longshore sediment transport (LST), including the effect of the spectral shape associated with the free surface displacement. The expression is derived theoretically by using the wave flux approach in conjunction with the spectral representation of the wave field propagating to the coast. The resulting expression possesses the simplicity of implementation of classical LST formulae, with the additional feature of including a dimensionless coefficient encapsulating the spectral shape influence. The reliability of the proposed formula is assessed against the results of pertinent field data. Furthermore, its adequacy is investigated in the light of existing formulae. In this article, we show that the proposed LST formula is capable of reducing the large overestimations associated with the LST calculation and of reducing scattering between calculated and the measured LST rates.
