  abstract = {{T}he problem of sandbar migration on the storm timescale is revisited with a 3{D} wave-resolving hydro -sedimentary model. {T}he latter presents an intermediate approach between expensive wave-resolving two-phase flow models and highly parametrized wave-averaged models. {I}nnovative features include the use of weakly compressible assumptions in the hydrodynamics and morphological acceleration of bed changes to speed up numerical simulations. {T}he model accurately simulates the successive offshore and onshore bar migration observed in a large-scale flume experiment in response to wave forcing representing storm and post-storm (recovery) conditions. {T}he diagnosis of sand transport and the analysis of an ensemble-averaged asymmetric wave cycle reveal the migration mechanisms in each phase. {I}n all cases, sediment resuspension is impacted by breaker-induced turbulence, while sediment transport and bed evolution are primarily the result of the undertow distribution - the breaker-induced seaward undercurrent - across the sandbar. {T}here is also a significant contribution from asymmetric wave-related onshore fluxes, due to greater mobilization and currents during the wave crest period.},
