Three-dimensional Hydrodynamic Analysis of Yushan Petrochemical Reclamation

Abstract

With the help of Mike 3 software, a three-dimensional hydrodynamic mathematical model was built for Daxiaoshan sea area. The model was calibrated and verified by the measured tidal current and tidal level data. The influence of Daxiaoshan reclamation project on the surrounding hydrodynamic conditions was analyzed by the numerical simulation of tidal current. The results show that in the model verification, the tide level only has a little deviation in the neap tide stage, and the velocity error is controlled within 0.4m/s. The influence of reclamation projects is mainly concentrated in the vicinity of reclamation areas and has no influence on the hydrodynamic conditions in a large area of sea. The three-dimensional effect of the positions of the southeast and southwest dikes is obvious, and the vertical velocity distribution of the south dike is the most uneven because of the complex terrain conditions. Using the Mike 3 hydrodynamic module can better simulate the flow field distribution in the engineering area and the surrounding sea area of the project, and can better guide the construction of related projects.
