Water quality is an emergent property of a complex system comprised of interacting microbial populations and introduced microbial and chemical contaminants. Studies leveraging next-generation sequencing (NGS) technologies are providing new insights into the ecology of microbially mediated processes that influence fresh water quality such as algal blooms, contaminant biodegradation, and pathogen...
As the forefront of complex nonlinear science and artificial intelligence science, artificial neural network has began to be applied in the field of water quality control and planning step by step. According to the fuzzy feature of water quality information, this paper proposes a membership degree Back-Propagation network (MDBP) for water quality assessment with combining fuzzy mathematics and ...
This study investigates spatial water quality assessment of selected river basins in the three different states in Malaysia. Environmetric techniques namely, cluster analysis (CA), principal component analysis (PCA), and discriminant analysis (DA), were applied to study the spatial variations of the most significant water quality variables in order to determine the origin of pollution sources ...
The paper aims to evaluate the role of faecal coliforms in assessment of water quality. The study was conducted on the Neretva River in Bosnia and Herzegovina. The sampling was performed bimonthly, over 12 months at seven selected sites. APHA (1995) methods were used. The raw data of temperature, pH, conductivity, oxygen saturation, nitrogen, total phosphorus, and faecal coliforms were transfor...
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...
In this Focus article, the authors ask a seemingly simple question: Are harmful algal blooms (HABs) becoming the greatest inland water quality threat to public health and aquatic ecosystems? When HAB events require restrictions on fisheries, recreation, and drinking water uses of inland water bodies significant economic consequences result. Unfortunately, the magnitude, frequency, and duration ...
Abstract The energetic nature of these important water resources makes them the most vulnerable to contamination from additional waste multiple sources. Water quality monitoring is critical environmental management, and successful provides direction confirms effectiveness management. Models based on artificial intelligence are fundamental for anticipating appropriate moderation measures surface...
