Numerical Simulation and Experimental Study of Hydrodynamic Characteristics Based on Dynamic Programming Algorithm

Mike software is a kind of numerical simulation software, which is usually used to analyze environmental problems such as water flow and water quality changes in lakes, rivers, and oceans. The MIKE 21 model includes multiple modules, among which the hydrodynamic simulation module is the core of the MIKE 21 model and is the basis for the simulation of other modules. Aiming at the influencing factors of the artificial lake hydrodynamics, this paper establishes the MIKE 21 hydrodynamic simulation model, and uses the dynamic programming algorithm to analyze the influence of factors such as throughput, wind direction, water level on the hydrodynamic characteristics, and analyzes the distribution characteristics and changes of the artificial lake flow field. rules, thereby helping to regulate and improve lake water conditions. In this paper, the dynamic programming algorithm is used to analyze the numerical simulation results of the water flow field of the artificial lake, and it is obtained that the initial simulation error of the MIKE 21 hydrodynamic model is relatively large.
