In this research, spatial – temporal variations of water quality in the fluvial components Hasana?a Stream Basin were evaluated by using Water Quality Index. Surface samples taken from seven stations selected on basin winter seasons 2019 and 2020. Eleven variables including dissolved oxygen, oxygen saturation, pH, electrical conductivity, total solids, salinity, turbidity, nitrate, nitrite, pho...

fuzzy water quality index (fwqi) was applied in order to assess the degree of drinking water resources in yazd province, iran. thisstudy has also offered the creation of a new fuzzy water quality index (fwqi) to evaluate this tool’s applicability. 12 chemicalparameters including toxic and non-toxic heavy metals measured in 71 groundwater samples collected from drinking water resourcesin rural a...

The present study aims to have a comparative study of the results, from biological monitoring as well as conventional method, based on physico-chemical variables. Water quality index (WQI) and planktonic diatom metrics have been used to determine water quality and ecological conditions of the Dong Nai River (DNR) and Canonical Correspondence Analysis (CCA) to find out the main environmental var...

The rapid development of industrialization and urbanization in the world impact increased water pollution. Human activities, such as dam constructions, excessive consumption, severance river flows, compaction riverbanks, use riverbed vegetation, disrupt flow alter original hydrological cycle. In response to these conditions, this study aims analyze quality status set up a watershed environmenta...
