Abstract

In this study, a conflict resolution methodology for water quality management in a river system is presented. The proposed model maximizes an objective function based on the Nash product which includes different utility functions related to the water quality deviations from the standard limits. Simulation and optimization models are proposed to determine operating policies for river water quality management, based on evaluation of system performance to derive the most appropriate diffusing strategy for different stakeholders. The proposed model includes an integrated GA–based optimization and a water quality simulation model. Sustainability measures of system performance, termed "reliability, resiliency, and vulnerability", are calculated for each water withdrawal sector and combined into a Nash product as an objective function. The model is applied to the Karkheh River system in the southern part of Iran. The utility functions are based on the acceptable risk of the allocated water quality by different sectors, especially by the Environmental Protection Organization. The results of the proposed model show that the waste load allocation policies can significantly reduce the number and duration of deviations from the standard quality limits
