Evaluation of the performance of river water quality monitoring stations of Iran

One of the basic issues of that country is monitoring system. The monitoring process is carried out by considering the managerial and technical, social, economic and environmental indicators in the monitoring system. Consecutive assessment, pathology and optimization in long-term monitoring; Leads to proper management of output data, system efficiency and reduces costs. In this study, multi-criteria decision making methods have been used to evaluate the performance of the quality monitoring network of the country's rivers by considering various criteria. In this study, the total quality stations of the country's rivers with four main criteria including: economic, social, environmental, managerial and technical have been considered. The weight of the criteria is determined by experts. The weight of the options is calculated using mathematical standards and the network analysis process method. The network analysis process method is proposed in order to modify the hierarchical analysis process method based on the technique of sup matrices. Finally, the results of the method were controlled using the network analysis process method, compatibility ratio and sensitivity analysis. Most of the challenges in the managerial and technical criteria, then the environmental and water health criteria are considered important, and finally the next economic and social criteria are obtained. In the managerial and  technical criteria in water monitoring stations, the sub-criterion of data quality control and assurance, in the social criterion sub-criterion of water quality parameters, in the economic criterion sub-criterion of pollution detection and in the environmental criterion sub-criterion of optimization of monitoring network at specific time and place.
