The Integrated Weight Water Quality Index (IWQI) is a ranking system that indicates the overall impact of physicochemical characteristics on water quality, as determined by the Water Quality Index (WQI). In this work, IWQI was used to evaluate water quality58,59,60,61. IWQI computation consis...
water quality index formulalogarithm functionBased on hypothesis of "base value" of water quality parameter, a universal index suitable to multi-parameter water quality evaluation was presented, as the monitoring values of parameters in the water quality index formula in logarithm function form were ...
Evaluation of the surface water quality using global water quality index (WQI) models: perspective of river water pollution Md. Habibur Rahman Bejoy Khan, Amimul Ahsan, M. Imteaz, Md. Shafiquzzaman & Nadhir Al-Ansari Scientific Reports volume 13, Article number: 20454 (2023) Cite th...
(2006) developed a water quality index (WQI) that takes the specific characteristics and uses of a given water resource into consideration and applied this method to the water quality assessments of Lake Kinneret in Israel and Lake Narach in Belarus. Huang et al. (2014) developed a water ...
This study aims to design different water quality index (WQI) models to provide policymakers, stakeholders, and water managers with a more comprehensive assessment by converting complex datasets from over 10 years, processed with the statistical software R, into consistent data sets. These datasets ...
While WQI classified 14 of the samples as ‘excellent’ and 17 as ‘good’, IWQI put all of them under ‘unsuitable’ category. This led to the development of a new index, called ‘comprehensive water quality index (CWQI)’, on the basis of analytical hierarchy process (AHP). Unit ...
The aim of this paper is to present a new approach to assessing water quality by using a new index: "Total Water Quality Index" ("TWQI"). TWQI Method has advantages over other methods in evaluating water quality and has been applied in Belgium, the United States of America ("WQI") ...
Water Quality Index (WQI) The Water Quality Index (WQI) analysis provides a comprehensive picture of the quality of surface and ground water for most domestic uses. WQI is defined as a rating that reflects the composite influence of different water quality parameters (Sahu and Sikdar 2008). It...
To overcome this limitation and to improve the assessment of water quality characteristics, the Water Quality Index (WQI) was developed. The WQI employs a numerical formula to transform water quality attributes into quantitative scores, thereby providing a representation of the overall water quality ...
Predicting a water quality index (WQI) is important because it serves as an important metric for assessing the overall health and safety of water bodies. Our paper develops a new hybrid model for predicting the WQI. The study uses a combination of a convolutional neural network (CNN), clockwor...
