As the new urban core area and the center of Dalian, Pulandian Bay shoulder the mission of the coastal economic growth in Liaoning province. In view of the present urgent pollution situation in the coastal waters , the MIKE 21 Flow Model is used to build the two-dimensional tidal current field and replay the basic situation and the trend of variation of the bay. Model validation results show that the calculated values agree well with the measurement values, and the model can reflect the tidal current field of Pulandian Bay accurately. The numerical simulation results provide the scientific basis and basic data for the sea area construction and environmental protection.

2D Numerical Model

Taking Yangshan sea-area of the Qiqu archipelago as an example, a 2D numerical model of tidal currents is established to study the change of the current field and the influence of branch blocking in different stages of northern port construction, including tide process, velocity and tidal prism, in the main channel waters and the branches. Verifications with the observed data indicate that the simulated results can reflect the current fields in the region. Based on the numerical model it is rechecked and researched the influence of branch blocking in different stages of northern port construction on the changing processes of hydrodynamic, including tide process, velocity and tidal prism, in the main channel waters and the branches. The paper is to provide the scientific basis for the construction of Yangshan Port’s subsequent engineering.

Sediment Model

Based on the 2-D tidal current and sediment model, the field of tidal current near the sea of the secondary Diaoliang reclamation in Zhoushan was simulated due to the construction of the southern dike. After the simulation , the result was varified by the measured data .The impact on the surrounding sea and the annual change in erosion and deposition after the project was analyzed. The results show that the local current velocity in the eastern side of Luomen sea area features obviously decrease because of the reclamation project.The deposition is presented in the Diaoliang bay with the mean siltation intensity of around 0.8m/a, as well as about 1.1m/a of Luomen wharf apron .

The numerical simulation of tidal current field in wide and shallow waters (Naochao River) of Caofeidian industrial zone is carried out by using a two-dimensional hydrodynamic model, taking the discharge problem of temperature and drainage in a refinery integration project as an example. Taking the tidal current field as the hydrodynamic condition of the temperature drainage transport simulation, the concentration distribution of the temperature drainage in the receiving water area was predicted by using the two-dimensional convection-diffusion model of the temperature drainage, and the change of the temperature rise line and its influence were analyzed. The results showed that the water area affected by temperature rise in winter and summer were 0.28km2 and 0.35km2, respectively, when the project was discharged separately. The existing temperature displacement of China Resources Power Plant in the superposition area is: 19.1km2 in winter and 1.64km2 in summer under the influence of temperature rise. By analyzing the influence degree of wide and shallow water (Naochao River) drainage outlet on temperature rise, the conclusion that the layout of drainage outlet should be further optimized is given. conclusion that the layout of drainage outlet should be further optimized is given.
