1Small river basin and estuarine sediment fluxes:The magnitude necessary for coastal dispersion and siltation effects on a coral reef显示文摘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 processes.In Brazil,a small coastal basin(Macae River)was identified as a source of suspended sediment to a coral reef on the coast of Cape Arma?ao dos Búzios.Biannual suspended sediment loads were measured at the basin as were fluxes within the estuary and towards the coast during eight tidal cycles.Particle load and yield from this basin were typical of small coastal basins,showing high to moderate slopes and transitional land management.However,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 reef.Nonetheless,the estuary displays both suspended particle retention and export capacity and,therefore,fluxes to the coast and the coral reef occur as episodic events.Paula Sagiliao Isacksson Eduardo Guilherme Gentil de Farias Francisco Jose Dias Roberto Nascimento de Farias Anandra Machado Francisco de Assis Esteves Mauricio Mussi Molisani 2019International Journal of Sediment Research2019,34,6:0
