A Long Distance Estuary Scouring Quasi-2D Numerical Model for the Lower Yellow River and its Estuary

According to the properties of incoming water and sediment, and the fluvial evolution law in the lower reach and estuary of the Yellow River, a long distance numerical model, which simulate high - concentration water and sediment movement, aimed to predict the sea water scouring effect, based on the field water stage, water depth, velocity, sediment concentration data of Aishan cross - section to river mouth and the lower reach quass - 2D unsteady sediment model in the Yellow Rivers, is established and verified. The calculated results, which include the total quantity of erosion & deposition and water stage along the river, are good agreement with the field data. So the model is reliable and usable.
