The Research on Flow and Water Quality Numerical Simulation for Urban River Network in Fuzhou

In this paper, according to the previous studies and water body´s hydrodynamic and quality features in the tidal river network region, one-dimensional hydrodynamic and water quality model is established and validated. The results show that the calculated value of hydrodynamic model can better match the measured and reflect the tidal fluctuation trends accurately, and water quality model can reflect the changes of contaminants reverberating within the river network in the impact of fluctuation in tide. This study with a certain directive significance provides a theoretical foundation to solve the problems of water environment of Fuzhou City.
