Impact assessments of water allocation on water environment of river network: Method and application

Publication date: Available online 2 February 2017 Source:Physics and Chemistry of the Earth, Parts A/B/C Author(s): Qinggai Wang, Yaping Wang, Xuchuan Lu, Peng Jia, Beibei Zhang, Chen Li, Sa Li, Shibei Li Two types of water allocation senarioes were proposed for reasonably utilizing water resources and improving water quality in a two-river network in Tongzhou District. Water circulation and quality were selected as two important indexes to evaluate the two senarioe. Meanwhile, one-dimensional water amount and quality model was set up on the basis of the MIKE11 model to compare the two senarioes in terms of improving water environment. The results showed that both senarioes changed the hydrodynamic conditions, and consequently the river flow reached 0.05 m/s or higher in the central part of river stream. In addition, we also found that the two plans have similar effects on water quality, with first senarioe producing larger area of water class III and IV than the second senarioe.
