Two-dimensional Finite Element Mathematical Model of the Yellow River Estuarine Sediment and Its Application(I) ——Model and Verification

In this paper, the necessity of establishing finite element model of the Yellow River estuarine sediment is analyzed, and the two-dimensional tidal current and sediment model in the Yellow River estuary area is established on the basis of the practical Yellow River estuary condition. It is shown from the verification results for the computed tidal level, tidal current and sediment scour and deposition that the simulated tidal level and current values and the computed sediment scour and deposition variations are consistent with the observed data, which indicates that the two-dimensional finite element estuary sediment model can be used to simulate the Yellow River estuary sediment movement and predict the estuarine seabed scour and deposition variations.
