Abstract This study aims to investigate the tidal variations of hydrology and dissolved nutrients, based on exten-sive field measurements during January 3~10, 2016 in the Humen outlet of the Pearl River estuary, and

to indicate the nutrient dynamics. The concentration of NH 4 varied from 0.59~2.06 mg/l, 1.20~3.54 mg/l for NO 3, 0.14~0.49 mg/l for NO 2, and 0.025~0.063 mg/l for PO 4 during the sampling time, which demon-strates a significant difference in tidal changes. Salinity and suspended sediment fluctuated with tides, and no big tidal difference was found in water temperature. The role of marine waters on the dilut-ing-mixing process of nitrogen was stronger than that on phosphorus. Compared with nitrogen, phos-phorus was scarce in this study, and was a limited factor. The results enable us to develop effective coastal management and to benefit from more focused studies in the functioning of ecological health.
