Numerical simulation of water particle transport trajectory in the artificial Jiaolai Canal
胶莱人工河道水质点输运轨迹的数值模拟

Tidal flow of the artificial Jiaolai Canal was simulated by a two-dimensional hydrodynamic model. Lagrangian trajectories of water particles and the variation of water elevation were analyzed with or without consideration of a submerged dike at the entrance of the Jiaozhou Bay. It was shown that the artificial Jiaolai Canal could promote the sea water transport from the Jiaozhou Bay of the Yellow Sea to the Laizhou Bay of the Bohai Sea, but the mean flow velocity was small before submerged dike being built. Had a submerged dike been built, the duration, during which the water level of the Jiaozhou Bay was higher than that of the Laizhou Bay, would become longer and thus speed up the water transport from the Yellow Sea to the Bohai Sea. In addition, if the distance between the top of the submerged dike to the mean water level were small.The water transport from the Yellow Sea to the Bohai Sea would be faster.
