Estuary Geometric Feature ’s Effecting on Salt-Fresh Water Mixing
A three dimensional unstructured model was established and estuaries with different cross sectional divergence rates and different bed form were designed to study the estuary geometric feature effecting on salt-fresh water mixing in estuary. The model dispersing 3d domain into unstructured triangular and/or quadrangular elements, has good flexibility to simulate complex bank. By analyzing the horizontal and longitudinal distribution attributes of velocity and salinity field, the effects of cross section divergence rate, the bottom elevation of mouth and the slope inside estuary on salt water intrusion in estuary are studied. The result could act as design basis for the engineering projects which will change estuary’s bank shape or bed form such as estuary regulation and channel dredging.
