“…This is because the habitat quality in no-weirs reaches is determined by velocity and not water depth (except for the HSR at a discharge of 70 m 3 /s). Improving the habitat quality of rivers should not be based on experience, as some recognized measures for improving habitat quality may not be effective under certain conditions [55] or may have different effects depending on the discharge and layout conditions [56,57]. These findings are similar to our research conclusion; that is, the impact of hydraulic engineering on habitat quality will vary according to flow and layout conditions.…”

“…Habitat simulation models mainly include the1-D PHABSIM model, EVHA and HABITAT models, the 2-D RIVER2D model and the 3-D software, etc. The 1-D model cannot adequately simulate the hydrodynamic characteristics in habitat assessment, while DELFT3D is mostly used for the analysis of the internal flow field of water bodies, especially in the aspect of pollutant diffusion (Ma et al 2020). RIVER2D closely combines hydraulic simulation with ecological simulation, which is mainly used for the simulation and evaluation of microhabitats (water depth, velocity, and bottom sediment, etc.).…”

“…The flow velocity in this region is about 25-30% of the mainstream velocity [7]. Such structures are beneficial for improving the habitat of aquatic organisms in urban rivers [14].They create shelter for aquatic species, increasing their diversity. Weak and little fish shouldn't be swimming in the river's main channel because of the high velocity.…”
