摘      要：Increasing continental suspended sediment influx to coral reefs is an example of land-sea coupling that requires the identification of sources,magnitude of transport,and controlling *** Brazil,a small coastal basin(Macae River) was identified as a source of suspended sediment to a coral reef on the coast of Cape Armacao dos *** suspended sediment loads were measured at the basin as were fluxes within the estuary and towards the coast during eight tidal *** load and yield from this basin were typical of small coastal basins,showing high to moderate slopes and transitional land ***,the magnitude of the river loads was lower than the sediment transport within the estuary,indicating that the estuary amplifies river fluxes and sustains the transference of suspended sediment alongshore to the coral ***,the estuary displays both suspended particle retention and export capacity and,therefore,fluxes to the coast and the coral reef occur as episodic events.
