Hydrodynamic numerical simulation of lake ecological water diversion based on MIKE21

Abstract

In the steady development of social economy, the development of various countries based on the frequent occurrence of extreme events in the lake ecosystem, the lake ecological water transfer, which can not only develop a more perfect project management system, but also according to the relationship between the lake interior, for the prevention and control of ecological environment pollution put forward appropriate treatment countermeasures. In this paper, the MIKE21 software was used to build a mathematical model for the lake ecosystem, and the numerical simulation was carried out in combination with the characteristics of the hydrodynamic environment in a certain area. According to the data obtained from the measured analysis, the model is verified and analyzed. The final results show that the simulated results are basically consistent with the actual measured data, which proves that the numerical simulation method based on MIKE21 software is an important means to understand the hydrodynamic environment of lake ecological water transfer at present.
