模型准确性排名为WQIS > WQIW > WQIL。 改进的WQI模型: 该研究的改进WQI模型,融合了机器学习、组合权重和新的聚合函数,有效降低了不确定性并提高了准确性。建议使用WQIS模型来评估较差水质,而WQIW模型则适用于评估较好水质。 水质评估: 利用优化的WQI模型对朝柏河流域进行的评估显示,该流域被分类为二类水,表明...
Water Quality Index (WQI) computed based on certain hydrogeochemical parameters is one of the most effective tools to understand the overall quality and suitability of water for drinking, irrigation and industrial purposes. The spatial variation of the same can demonstrate the percentage of pollution...
由于河流是人类的主要淡水来源,所以定期评估河流水质十分重要,本文采用水质系数(Water Quality Index, WQI)来评估河流水质。 文章简介 本文的研究区域位于勒克瑙,它位于北纬26°30'-27°10'和东经80°30'-81°13'之间,属亚热带湿润气候,4 月至6月为夏季炎热,12月至次年2月为冬季。其中,贡题河是一条重要的供水...

Water quality index (WQI) is a single value numerical expression to evaluate the quality of a given water body at a particular position and time. The present study on WQI is based on the analysis of water samples collected from the Damodar River (after confluence of Tamla Nullah (canal)) ...
In this section, we employ the water quality index (WQI) to conduct awater quality assessmentof the waters in the Third Pole rivers. The WQI is calculated as follows: WQI=1n∑i=1nAi=1n∑i=1nCiQi whereCiis the examined metal concentrations in the water andQiis the guideline threshold limi...
The present study was intended to calculate Water Quality Index (WQI) of an Subbarayanahalli, Iron Ore Mine, Sandur, Karnataka in order to ascertain the quality of water for public consumption, recreation and other purposes. This paper deals with the study on the influence of environmental ...

Water quality predictionEclipsingAmbiguityMonitoring water quality is essential for the sustenance of the ecosystem and various forms of life on Earth. The water quality index (WQI) models are the widely adopted approach to water quality monitoring. However, they received much criticism for the ...
Water quality was evaluated by a water quality index (WQI) based on these parameters, which are commonly used in WQI calculation. Generally, the water quality state was classified as “moderate” in LCB (mean value of 69.1). Meanwhile, the state varied obviously among the three groups, with...
