  abstract = {{T}he present work investigates cross-shore shoreline migration as well as its alongshore variability (with deformation) on timescales of days to years using 6 years of time-averaged video images. {T}he variability of the shoreline is estimated through empirical statistical methods with comprehensive reference to three scales of variability. {A}t the meso-to macro-tidal barred {B}iscarrosse beach, shoreline responds in decreasing order at seasonal (winter/summer cycles, 52%), event (storms, 28%) and inter-annual scales. {W}hereas seasonal evolution is dominated by wave climate modulation, short-term evolution is influenced by tidal range and surf-zone sandbar characteristics. {T}he influence of tide range and sandbars increases when timescale decreases. {T}his is even more the case for the alongshore deformation of the shoreline which is dominated by short-term evolution. {A}n {EOF} analysis reveals that the first mode of shoreline change time series is associated with cross-shore migration and explains 58% of the shoreline variability. {T}he rest of the modes are associated to deformation which explain 42% of shoreline variability.},
