Water Quality Evaluation and Influencing Factor Analysis of Nanwan Reservoir with a Bayesian Model Based on AHM-CRITIC Combination Weighting by SUN Geyao, DUAN Jingjing, ZHAO Jing

“…In a traditional Bayesian model,equal weights are assigned to different evaluation factors,and the difference in their contributions to water quality is thereby ignored.To address this problem,this paper introduces the attribute hierarchy model-criteria importance through intercriteria correlation (AHM-CRITIC) combination weighting on the basis of a traditional Bayesian model and constructs a Bayesian model for water quality evaluation based on AHM-CRITIC combination weighting.The water quality of Nanwan Lake and the water quality grades of the main tributaries inflowing into Nanwan Reservoir are quantitatively analyzed with the model by using measured monthly water quality data of reservoir sections and main inflow tributaries from 2012 to 2020,and the results are compared with those of other methods.The following findings are obtained.① From 2012 to 2015,Nanwan Lake basically maintained the water quality at the Class III standard.However,from 2016 to 2020,the water quality did not meet the Class III standard occasionally,with water of Class Ⅳ even appearing.The water quality of the Dongjiahe section was poor,while the water quality of the Xiaoshihe,Tanjiahe,Wudaohe,and Xijiahe sections was good.② The results of the Bayesian model with combination weighting for water quality evaluation are more consistent with those of the single factor index method and the improved Nemerow index method.Overcoming the shortcomings of the subjectively weighted Bayesian method,the proposed model can reflect the water quality of the reservoir more realistically and provide a technical basis for similar water quality evaluation.…”

DATA VISUALIZATION AS A MEASURE TO IMPROVE THE EFFECTIVENESS OF SURFACE WATER QUALITY ANALYSIS by Ekaterina G. Larina

“…The efficiency of using some techniques (graphical representation of data, Shewhart control maps, box-and-whiskers diagram, and scattering diagram) for analyzing the results of water quality control of the Moscow river and some of its tributaries is demonstrated. It is shown that the methods of visual analysis allow you to visually display any changes in the quality of surface water and can become an effective tool in the organization of water use in the metropolis.…”

Research on River Health Assessment of Hanjiang River Basin by ZHANG Yajuan, ZHAO Xiaochen, CHEN Jipei

“…Health assessment of rivers and lakes is an important means of their health management.To meet the requirements of ecological civilization construction and river chief system in the new circumstances,this paper performs the classified assessment and comprehensive evaluation of the Hanjiang River Basin from five aspects:hydrological integrity,morphological and structural integrity,chemical integrity,biological integrity,and the sustainability of social service function according to the relevant methods in the Technical Guidelines for River and Lake Health Assessment (SL/T 793—2020).The assessment results show that the Hanjiang River Basin is in a state of health overall,and the score of the main stream of the Hanjiang River is slightly higher than that of its tributaries.The hydrological integrity and biological integrity of the sub-criterion layer are weak,which leads to the ecological conditions in a state ranging from sub-health to health.The social service function of the sub-criterion layer is sustainable,and the functional status is in the state of health.The health assessment of rivers and lakes in the Hanjiang River Basin is of great significance to promote its water resources protection and water environment management and ensure the sustainable utilization of its water resources.…”
