Tidal current analysis for Dapu berth extension project of Binzhou Harbor

Two-dimmension tidal mathematical model of Tao-er River about 15 km reach was established.The model was verified with the nature data,and the calculated result of model was consistent with the nature data by adjusting some parameters.Then the tidal flow characteristic was analyzed based on the simulation of tidal water level and tidal current in nature.Finally the mutual reaction of different extension plans and tidal flow were simulated.The outcomes of the three berth extension plans were summarized and compared by analyzing the tidal flow characteristic of the layout plans.The 3rd layout plan was the best one,on which the tidal current direction consistent with river bank,the velocity increased and no circumfluence.As a result,the berth depth was steady,watercourse was broad that convenient for ship pass-in-and-out,and constructing on bank became more advantage.
