Abstract

The application relates to a quantitative simulation method for water quality response of a target water body under different inflow and outflow scheduling scenarios based on an IWIND-LR model, and belongs to the technical field of water resource management. The method comprises the following steps: establishing a hydrodynamic-water quality-ecological model of the target water body based on an IWIND-LR model; adjusting a momentum equation, a water quality equation and an algae equation in the model based on the hydrodynamic and water quality mechanism processes corresponding to the inflow and outflow scheduling, specifically comprising adding an inflow flow term and an outflow flow term in the momentum equation, adding an inflow water quality term and an outflow water quality term in the water quality equation, and adding an inflow algae term and an outflow algae term in the algae equation, so as to quantitatively express the influence of the inflow and outflow on the hydrodynamic and water quality processes of the target water body; coupling the adjusted momentum equation, water quality equation and algae equation with a hydrodynamic-water quality-ecological simulation framework of the IWIND-LR model, generating an inflow and outflow scheduling model of the target water body through boundary condition setting, specifically comprising rebuilding a gridded hydrodynamic simulation module, a gridded water quality simulation module and a gridded ecological simulation module based on the adjusted equations, and coupling based on the simulation framework of the IWIND-LR model; formulating an inflow and outflow scheduling scenario scheme; simulating the different inflow and outflow scheduling scenarios through the inflow and outflow scheduling model, and generating water quality response simulation results of the target water body under each scheduling scenario.
