Research on Internal and External Water Circulation System in Dongying City Based on MIKE 11 Model

This paper builds a dual water circulation system in Dongying City through power improvement and water source supplementation, with an external circulation in the replenishment period and an internal circulation in the non-supplementary period. For the internal water circulation system, by using MIKE 11 to build a hydrodynamic model of surface water, the flow velocity and water level distribution along the route under different pumping station scales are analyzed, so as to achieve the scale of Dongba Road pumping station with sensory flow effect (flow velocity 0.05 m/s); external water circulation The system refers to the use of Caodian Main Canal, Shengli Main Canal and Lunan Main Canal for water supply to ensure that clean water enters the city.
