Research on Flood Control Evaluation of Wharf Engineering Based on MIKE21 Model
To evaluate the flood control safety of a dock project in Nansha District,Guangzhou,this paper uses MIKE21 hydrodynamic model to simulate the changes in hydraulic elements such as water level,flow velocity,and flow direction before and after the construction of the project under the condition of a 200 year flood.The model calculation analysis shows that after the construction of the project,the maximum water level rise does not exceed 0.007m,the flow velocity decreases by no more than 0.39m/s,and the maximum flow direction deviation does not exceed 13°.The research results indicate that the construction of the dock project will not have a significant adverse impact on the flood control and river regime of the river section where it is located.
