感潮平原河网水流水质计算模型应用研究

Research on water quality with hydraulic computation model in plain tidal river networks

根据平原河网在不同水文时期关注的目标,应用建立的水流水质计算模型,对研究区历史发生的5场洪水水流进行了验证,并对现状枯水期水流和水质进行了计算。结果表明,模型对洪水水流预报和枯水水流及水质计算都能达到较高的精度。通过研究区河网水环境现状验证,提出了枯水期相应的水质改善方案,为地区河网水资源的综合利用及水环境管理提供了决策依据。

For objects focused differently by the distinct hydrologic period in plain river networks, through the model of water quality with hydraulic computation, five flood cases were simulated and validated which happened between 1998 and 2001. Hydraulic factors and water quality of low water period in 2006 were computed in study area. The results show that precision in computation was high for the floods forecast in flood period and hydraulic factors and water quality simulation in low water period based on the model. Schemes on improving water quality were afforded by combining water environments in Yuyao river network. These could be as bases for decisions making in water resources integrative utilization and water environments management.
