  abstract = {{T}he {A}mazon yields the largest freshwater discharge to the world ocean, outflowing on a shallow, macro-tidal shelf. {I}ts plume dynamics is complex and the impact of the discharge on the tidal properties on the adjoining shelf remains poorly understood. {T}hrough a series of numerical modelling experiment, we investigate the interaction between the {A}mazon discharge and the tide over the {A}mazonian shelf. {W}e find that the runoff is responsible for a rise of the {M}2 tidal amplitude of ten cm in the embayment between {C}abo {N}orte and {C}abo {C}assipore. {T}he runoff also induces a rise of the mean sea level there, of 10 cm as well. {S}uch a one-to-one sensitivity of the tidal amplitude and of the mean sea level over this region is quite unique among the world coastline. {T}he modulation of the bottom friction by the thickness of the water column as well as by the vertical density stratification in the {A}mazon plume appears to be the main forcing factor of this response. {O}ur numerical sensitivity experiments suggest that the seasonal variability of the {A}mazon discharge has little impact on the temporal variability of the tidal characteristics over the {A}mazonian shelf.},
