| Abstract: | Trans-jurisdictional conflict in both water quantity and quality is a general concern in large river basins. In this paper, the relative utility function combined with the asymmetric Nash bargaining method was established to analyze the trans-jurisdictional conflict between water quantity and water quality in the Zhangweinan Canal Basin in China. The basin was divided into four conflict stakeholders, namely, Shanxi, Hebei, Henan, and Shandong Provinces, based on administrative unit. The water usage and pollutant discharge scheme for multiple stakeholders was optimized using the established model to satisfy the environmental flow and water quality objectives at the identified conflict sections. The results indicated that the total water consumption was reduced from 4.38?×?109?m3 in 2007 to 1.97?×?109?m3, and that the allowable COD and NH3-N discharged into the river was less than 3.8?×?104?t and 4.3?×?103?t, respectively. About 81.1 % of COD and 76.1 % of NH3-N should be further reduced compared with the values in 2007. |
