Water quality indices (WQIs) are used for the simple assessment and classification of water surface sources. However, considerable time, financial resources, effort required to measure parameters their calculation. Prediction WQIs through supervised machine learning is a useful approach reduce cost analysis development predictive models with reduced number parameters. In this study, regression ...
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...
Water Quality Index and Environmental Assessment of Rosetta Branch Aquatic System, Nile River, Egypt
This study was carried out on Rosetta branch water and 3 drains (El-Rahawy, El-Soble El-Gezira) that discharging wastewater into it, to assess the Water Quality Index (WQI) of their waters. investigation performed during period starting from winter 2017 summer 2018. The mean annual averages WQI values were good poor for irrigation (up 55) very aquatic life 97) at stations exposed discharged bra...
The current study was conducted to assess the water quality of Valley Duhok as a source for drinking livestock and poultry in region. Seventy-two samples were collected from six sites valley conduct physicochemical biological tests, sub-index model (WQI) applied quality.The results index indicated that Dam Lake (site N1) good poultry, while rest on category very poor animals, with WQI values ra...
Background: Survey of pollution and evaluation of water quality in rivers with Oregon Water Quality Index (OWQI) and GIS are effective tools for management of the impact of environmental water resources. The information in calculating the WQI of Moradbeik river allowed us to take our tests results and make a scientific conclusion about the quality of water. GIS can be a powerful tool for develo...
The practice of river quality classification usually uses Water Quality Index (WQI) to evaluate the WQI values river. However, due huge data collection on pollution with uncertain water parameter values, need a different approach classify quality. One supervised algorithms known as K-Nearest Neighbors (KNN) seems give new for where each points are classified according k number or closest neighb...
Groundwater is regarded as the primary source of agricultural and drinking water in semi-arid arid regions. However, toxic substances released from sources such landfills, industries, insecticides, fertilizers previous year exhibited extreme levels groundwater contamination. As a result, it crucial to assess quality for activities, both its current use potential become reliable supply individua...
Abstract Groundwater is an important source for drinking water supply in hard rock terrain of Bundelkhand massif particularly District Mahoba, Uttar Pradesh, India. An attempt has been made this work to understand the suitability groundwater human consumption. The parameters like pH, electrical conductivity, total dissolved solids, alkalinity , hardness, calcium, magnesium, sodium, potassium, b...
