The invention discloses a hydrodynamic
model system based on an MIKE 21FM model and an automatic parameter judging, setting, selecting and testing method, and belongs to the technical field of hydrodynamic
simulation. In order to solve the problems that in the prior art, MIKE 21FM
model parameters are complex to set, difficult to select and tedious in
verification process, an automatic parameter judging and setting
system is constructed; the
system can automatically judge and set
model parameters according to model characteristics and hydrological conditions of a research area, and meanwhile, automatically select proper parameters and verify and check the parameters, so that the rationality and reliability of the parameters are ensured. By means of the method, the efficiency and accuracy of MIKE 21FM
model parameter setting can be remarkably improved, and powerful support is provided for hydrodynamic
simulation; in addition, the method is also combined with a
machine learning technology to further optimize a parameter selection process and improve a
simulation effect; the method is widely applied to hydrodynamic simulation of rivers, lakes,
offshore water areas and the like, and has remarkable practical application value.
