In the last decades, water quality of river network in most Chinese cities has been worse than before due to the huge amount of wastewater discharges. Hence, in order to improve the river network environment, numbers of water diversion projects have been constructed in lots of these cities, which are widely acknowledged as effective projects to accelerate the river network flow rate and enhance the environmental capacity. In this study, two typical river networks are selected, which are Jiaxing river network and Wenzhou river network, located in northern and southern Zhejiang province, respectively. Since the water diversion projects in these two cities have been constructed and operated for years, it is necessary to evaluate the water quality improvements as well as the social benefits using a comprehensive evaluation system. Moreover, the health status comparison of these two different river networks is also made in this study to show the discrepancies between these two typical Chinese cities. The analysis and results in this study will be widely used in other Chinese cities in the future as a decision-making method for the construction of water diversion projects.
