Abstract Water quality assessment is key to the conservation and management of rivers. River Saraswati, a distributary river Ganga, serves as lifeline many villages in district Hooghly West Bengal, India. As gradually dying due diverse man‐made pollution, ten water parameters two sampling spots (PR‐1 PR‐2) are monitored month‐wise from March 2017 February 2020, these compared with those referen...

the zarivar lake a freshwater lake in west of kurdistan province is home for large number of native plant and animal species therefore water quality and health of the lake are vital for conservation of these species. the present study aimed at evaluation of the zarivar lake using nsf- wqi as an indicator of water quality. wqi is a suitable tool to examine and classify spatial and temporal varia...

the aim of this study was to assess the potential impact of trout farm effluents on water quality of zaringol stream based on nsfwqi and wqi indexes. some physicochemical water quality parameters were measured from 14 point during december 2009 to september 2010 seasonality. the average value of nsfwqi is 53.21 and it shows spatial and temporal variation. the maximum value or best water quality...

Groundwater is an essential resource for drinking and agricultural purposes in the Al-Jouf region, Saudi Arabia. The main objective of this study to assess groundwater quality irrigation region. Physicochemical characteristics were determined, including total dissolved solids (TDS), pH, electric conductivity (EC), hardness, various anions cations. index (WQI) was calculated determine suitabilit...

Environmental flow requirements, to maintain the functioning of freshwater-dependent ecosystems and restore rivers in ecologically acceptable conditions, depend upon the present water quality status of the river. Various stretches of Vishwamitri River vary in quality and quantity. Water quality index is a tool to converse information regarding water quality of various stretches of river and can...

Abstract The Water Quality Index (WQI) is a single, deferential metric for describing the state of water quality as whole, which aids in selection effective remediation strategies. Fifteen surface samples were taken from Euphrates AlHaydria neighborhood AL-Najaf (Iraq). Various physicochemical parameters, including pH, total dissolved solids (TDS), calcium, chloride, sulfate, and electrical con...

Abstract Water sources for irrigation systems in the Red River Delta are crucial to socioeconomic growth of region's communities. Human activities (discharge) have polluted water source recent years, and from upstream is limited. Currently, surface quality index (WQI), which calculated numerous parameters (physical, chemical, microbiological, heavy metals, etc.) frequently used evaluate systems...

Abstract Water quality assessment using water index (WQI) is performed based on major variables reflecting the river characteristics. We evaluated of tributaries Nam River in South Korea. analyzed spatial characteristics cluster analyses and selected main (Cluster 1: chemical oxygen demand [COD], total organic carbon [TOC], nitrogen, phosphorus; Cluster 2: temperature [WT], dissolved [DO], COD,...
