Description :
The paper describes hyperpycnal flows observed in situ off the Huanghe (Yellow River) mouth, their relationship to tidal cycles, and the mechanisms that drive them. Simultaneous observations at six mooring stations during a cruise off the Huanghe mouth in the flood season of 1995 suggest that hyperpycnal flows observed at the river mouth are initiated by high concentrations of sediment input from river and modulated by tides. Hyperpycnal flows started near the end of ebb tides, when near-bottom suspended sediment concentration (SSC) increased rapidly and salinity decreased drastically. The hyperpycnal flows have an important impact on both sediment dispersal and coastal morphology at the mouth of the Huanghe.
