Simulating Flow of An Urban River Course with Complex Cross Sections Based on the MIKE21 FM Model
In this case study, the method of unsteady flow was used to study the flow characteristics of a planned urban river course, River A, with complex cross sections, based on the MIKE21 FM hydrodynamic module, which is an important tool for analyzing and solving hydrodynamic problems. First, the rationa...
