  abstract = {{M}uddy coastlines cover much of the world's shores, yet studies on the interaction between mud-affected coasts and estuaries are limited. {T}his study focuses on the {M}ahury {R}iver estuary and its interaction with the muddy coast of the {G}uianas, primarily fed by the {A}mazon. {A} coupled wave-current-sediment transport model is developed to analyze the sediment exchange in an environment with strong interactions between the waves and the fluid mud. {S}imulations explore how seasonal changes in waves, mud availability, and tides affect sediment fluxes. {T}he main processes influencing suspended particulate matter ({SPM}) and sediment transport are well emulated, notwithstanding the complexity of the ambient muddy environment. {T}he results show that during the rainy season, strong wave damping and wave refraction zones cause high {SPM} resuspension in shallow waters (<5 m). {I}n contrast, during the dry season, wave influence shifts to the estuary mouth. {E}rosion and sedimentation patterns indicate that ebb currents associated with neap tides during the rainy season represent the most favourable conditions for the alongshore migration of mud banks. {N}eaptide ebb currents also contribute to sedimentation during the dry season but only in the estuary mouth and the nearby coastal area. {T}he abundance of mud leads to an extension of the estuary's intertidal area during the dry season.},
