Abstract In this study, a customized WQI (Seoul water quality index, S-WQI) for urban rivers that can ultimately reflect their characteristics was developed by modifying and supplementing the existing Bascarόn calculation method through linkage with statistical methods such as factor analysis. We used data generated monthly at 17 monitoring networks (WQMNs) in Seoul 18 years, from 2002 to 2019....

The quality of the water TigrisRiver passing through city Mosul was studied, starting from Kubba area in north to Yarmajah south, and is only resource for city. Physical Chemical propertiesof river conducted, which included (water temperature, pH, electrical conductivity, total dissolved solids, turbidity, oxygen some positive negative ions), Canadian Water Quality Index = (WQI) used express wa...

Given the complexity of water quality data sets, resources pose a significant problem for global public order in terms protection and management. In this study, surface drinking irrigation purposes was evaluated by calculating Water Quality Index (WQI) Irrigation (IWQI) based on nine hydrochemical parameters. The discriminant analysis (DA) method used to identify variables that are most respons...

Online approaches for monitoring water quality can be an alternative aid to rapid decision-making in watershed management, especially reservoirs, given their vulnerability the process of eutrophication. In this study, a modified index (WQI) was developed using parameters that are easily measured with sensors, which would allow online reservoirs. The WQI based on WQICETESB and we used regression...

The Wadi Fatimah area suffers from a lack of freshwater resources, so this study aimed to analyze the groundwater in region and evaluate its quality for irrigation drinking purposes. Eleven water parameters, including pH, total dissolved solids (TDS), Ca 2+ , HCO −3 NO F − Cl K + Mg SO 2 −4 Na were utilized produce index (WQI). These parameters measured at 100 different chosen locations. spatia...

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,...

Assessment of groundwater quality is important for drinking water, especially rural populations. The aim this study was to assess the human consumption by integrating water index with geographic information system (GIS) eventual interpretation Meknes area quality. Eight wells and two springs were investigated between February 2013 2014. In light analysis results, spatial distribution maps chose...
