Abstract

Abstract

The construction projects along the coast of Jinzhou Bay will inevitably affect the surrounding marine hydrodynamic environment and ecological environment. The paper simulates and calculates the tidal current field in the reclamation area of Jinzhou Bay by 2D hydrodynamic numerical simulation, and predicts the impact of airport artificial island shore connection project on the tidal current field and erosion siltation under different conditions. The results show that the tidal current is generally characterized by strong reciprocation, and the main flow direction of ocean current is NE-SW, with NE for flood tide and SW for ebb tide. The maximum possible flow velocity is 23.2-100.9 cm/s. When the opening width of land connection dam is 50 m and 200 m, the areas with obvious flow pattern changes are concentrated in the waters near the opening. The flow velocity in the opening channel and vicinity increases significantly, while that in the eastern waters of the northern land connection dam tends to decrease. When the opening width is expanded from 50 m to 200 m, the average siltation intensity in the siltation area increases from 0.06 m/a to 0.14 m/a.
