Tidal and prism analysis of sea reclamation project in coastal bay

Mathematical model analysis is very important in investigating the water exchanges and tidal prism in the reconstruction engineering projects around coastal bay. Based on the accurate simulation of tides, the mathematical model method is more economical and efficient than traditional measurement method and physical experiment model in the first evaluation of initial design. A robust numerical model with high accuracy is explored in this study for a systematic consideration of hydraulic interactions within different water zones in coastal reconstruction project. Application of the developed tidal model to a reconstruction project in the Dalian Laohutan Bay of China is presented in details. The developed tidal model with a refined meshing algorithm has been validated through measured field data with reasonable agreement. Then, the validated model is used to examine water exchanges and the tidal prism under different engineering reconstruction scenarios. The engineering solutions that satisfy the requirements of both project demands and environmental protection have been obtained.
