Near coast sediment transport is a challenge due to the complexity of wave-current interaction, but also because of the variety of acting phenomena (breaking waves, undertow …). Most transport formulae have been calibrated with experiments, but have a restricted range of application. Nonetheless, these formulae are often used beyond these ranges. The aim of this paper is to point out the limits of four of these formulae: the Engelund-Hansen, Bijker, Bailard and Dibajnia-Watanabe formulations. The sensitivity of the formulae to wave orbital velocity, wave period, sediment grain size and water flux has been studied. It appears that they behave in very different ways if one of these parameters is slightly modified.
