Numerical Investigation of the Sediment Hyperpycnal Flow in the Yellow River Estuary

Sediment hyperpycnal flow is one of the most important processes for mass transport, which essential to coastal morphodynamics. Herein, we studied generation and maintenance sediment in Yellow River Estuary (YRE) using a three-dimensional finite volume ocean model (FVCOM). The considered effect sediment-laden water on density stratification, was validated by field hydrodynamic data. Numerical results revealed that shows periodic characteristics with tidal cycles where weakened during flood tides enhanced ebb tides. A high suspended concentration (SSC) about 30–40 kg/m3 constitutes an factor formation flows. High river discharge SSC maintaining YRE.
