  abstract = {{I}n this article, based on the example of the {T}oliara lagoon in {M}adagascar, we identified the major impacts of the two main drivers of the water renewal in a typical channel lagoon: the tide and the swell breaking on the reef. {F}or this purpose, we applied the numerical model {C}roco which is based on {ROMS}-{AGRIF} and uses a realistic and high-resolution configuration. {T}he validation was performed with in situ {ADCP} data, then, realistic and sensitivity simulations were run to infer tides and waves role in ocean-lagoon exchanges and to estimate water age and water origin. {T}he modelling approach adopted enabled an understanding of the effects of swell and tide on the water renewal. {D}uring low wave conditions, tide and waves counteract each other on cross-reef flow: the cross-reef inflow tends to increase with waves breaking on the reef, whereas cross-reef flow tends to decrease or to be outflowing with tidal action. {H}ence, the lagoon-ocean exchange is reduced and is at a minimum when wave height reaches 0.85 m and the tide has minimum amplitude. {D}uring high wave conditions, both tide and waves increase ocean-lagoon exchanges by increasing the cross-reef inflow, whereas during low wave conditions, the cross-reef flow is mainly outward with increase with tidal amplitude and decrease with wave height until the threshold of 0.85 m.},
