evaluation of surface water quality is a complex process undertakingmultiple parameters. converting great amount of parameters into a simpler expressionand enabling easy interpretation of data are the main purposes of water quality indices.the main aim of this study is to plan effective water resources management system forkarun river by combination of ccmewqi and geographic information system ...

Water quality evaluation benefits monitoring the water quality, utilizing and developing water resources rationally, providing a basis for the planning of water pollution control strategies, and predicting the future trend of water environment scientifically. This paper proposes a combination approach that can be used to incorporate two or more water quality evaluation models. The application o...

The blind number theory was applied to define the blind numbers of the parameters of environmental system according to the characteristics of several kinds of uncertainties coexisting in water environmental system. Entropy coefficient method was calculate indicator weight based on the differences of water evaluation indicators and effectively solve the problems of weight calculation and effect ...

Australian ports serve diverse and extensive activities, such as shipping, tourism and fisheries, which may all impact the quality of port water. In this work water quality monitoring at different ports using a range of water quality evaluation indices was applied to assess the port water quality. Seawater samples at 30 stations in the year 2016-2017 from six ports in NSW, Australia, namely Por...

the development of a surface water evaluation index is a critical factor in the assessment, restoration and protection of stream water quality. quantifying water pollution in specific grade using dominant parameters is important, as this can explain the current state of water pollution with accuracy. as a result, an integrated multi-parameter water quality index has been developed. it is based ...

Although agenda of Water supply in sufficient quantity and standard quality is highlighted in India from last few years. But Yet Performance assessment and Efficiency evaluation of water supply services not in practice. However the analysis is confined to the realm of researchers and policy makers. The present paper spells inclusion of quality parameter in assessment of utilities through fronti...

Hodnotenie kvality mestskej vody použitím multivariacnej analyzy A data set, obtained for the sake of drinking water quality monitoring, was analysed by multivariate methods. Principal component analysis (PCA) reduced the data dimensionality from 18 original physico-chemical and microbiological parameters determined in drinking water samples to 6 principal components explaining about 83 % of th...
