  • Estuary eutrophication can affect both top-down and bottom-up ecological processes.
  • We elevated sediment porewater nitrogen to test effects on microphytobenthos and grazers.
  • Nitrogen enrichment doubled benthic microphyte biomass and altered macrofauna communities.
  • Enrichment effects did not alter sediment erosion threshold or rate.
  • Erosion of nitrogen-enriched sediment released substantial nutrients and chlorophyll a.
