زمینه و هدف: با توجه به اهمیت مصارف مختلف آب، هدف این مطالعه بررسی روند مکانی کیفیت آب رودخانههای کن و کرج با استفاده از سه شاخص NSFWQI، IRWQIsc و WQI است. مواد و روشها: اطلاعات پارامترهای کیفی آب از 20 ایستگاه پایش رودخانههای کن و کرج طی سالهای 1391-1392 جمعآوری و کیفیت آب دو رودخانه با سه شاخص کیفی نامبرده محاسبه شد. برای محاسبه شاخصهای NSFWQI و IRWQIsc از پارامترهای TDS، FC، EC، نیتر...
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...
مطالعات زیستی و بومشناختی منابع آب از مباحث اساسی در تحقیق و بررسی های علمی مربوط به منابع آب است. شناسایی ویژگیهای هر اکوسیستم، موجودات زنده و فاکتورهای محیط زیستی حاکم بر آن، گام نخست این مطالعات محسوب میشود. ارزیابی کیفیت منابع آب بخصوص منابع آب آشامیدنی در سالهای اخیر همزمان با کاهش کمیت و کیفیت منابع آب از اهمیت بسیاری برخوردار گردیده است. دریاچهها و مخازن آبی سدها به عنوان منابع مهم...
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...
Water quality index (WQI) is the primary method applied to characterize water in world. The current study employed statistical analysis and multilayer perceptron (MLP) approaches for predicting groundwater Ghiss-Nekkor aquifer, northeast of Al Hoceima, Morocco. Fifty sampled were identified analyzed major anions cations throughout May 2019. Several physicochemical parameters all samples this in...
Background and Objectives In recent years, excessive use of groundwater resources and the discharge of urban and industrial wastewater in the environment has contaminated and reduced the quality of groundwater resources. The aim of this study was to determine the quality of drinking water resources in Rafsanjan city using water quality index (WQI) in 2018. Materials and Methods: This descri...
