Abstract

As an important resource and environmental carrier, urban rivers are related to the survival of the city and restrict the development of the city. However, situations caused by environmental degradation, water pollution occurs in urban rivers. Therefore, comprehensive treatment of urban water pollution has become a necessity. This study establishes a two-dimensional Hydrodynamics and Water Environment (HWE) model based on MIKE21 FM, and then the simulation effect of the proposed HWE model is verified by comparison with the measured data. With Shenzhen city’s Guanlan River as a case study, the results indicate that (1) the water level and water quality of the proposed HWE model have a good fit; (2) the flow velocity of the main stream in the Guanlan River shows a gradual increase trend from the upstream to the downstream, that is, the average flow velocity values of the upstream, middle, downstream reaches are 0.034 m·s-1, 0.041m·s-1, and 0.183 m·s-1; and (3) the temporal and spatial distribution of the water quality parameters in the Guanlan River shows that the flow of river water has a diluting effect on the sewage discharged from the sewage treatment plant. These findings are helpful to the analysis of urban river’s hydrodynamics and water environment characteristics.
