A three-dimensional hydrodynamic and salinity transport model of estuarine circulation with an application to a macrotidal estuary

▸ A three-dimensional estuary model is developed based on orthogonal unstructured grid. ▸ A well-mixed estuary with strong tidal mixing is studied by the developed model. ▸ Hydrodynamic and salinity processes before and after a blocking project are studied. ▸ Saline water intrusion is studied under combined river inflow and tide conditions.
