Assessment of the Present State and Future Fate of River Saraswati, India: Water Quality Indices and Forecast Models as Diagnostic and Management Tools

CLEAN – Soil, Air, Water, Volume 51, Issue 4, April 2023., 2023
Water quality indexing based on actual and forecasted data reveals that river Saraswati in India is a dying river. Free carbon dioxide, dissolved oxygen, and turbidity appear as strong determinants. Three forecasting methods project that under a “business as usual” situation, the progressively degrading river will die soon.

A Type‐2 Fuzzy Logic Approach for Forecasting of Effluent Quality Parameters of Wastewater Treatment

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
In this investigation, we have studied and designed a type‐2 fuzzy logic controller (IT2FLC) for the wastewater treatment plant at Haldia, India. To avoid modeling complex physical, chemical, and biological treatment processes of wastewater, this present work represents an ensemble of fuzzy models as surrogates for the wastewater treatment plant (WWTP).

An Optimized Approach for Predicting Water Quality Features Based on Machine Learning

Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022
Traditionally, water quality is assessed using costly laboratory and statistical methods, rendering real‐time monitoring useless. Poor water quality requires a more practical and cost‐effective solution. The machine learning classification approach appears promising for rapid detection and prediction of water quality.

A Comprehensive Method for Water Environment Assessment considering Trends of Water Quality

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021
Water quality is a significant issue, and its assessment plays an important role in environmental management and pollution control. In this paper, we proposed a comprehensive water quality assessment method which takes into account both absolute and temporal trends in water quality.

River water quality management using a fuzzy optimization model and the NSFWQI Index

Water SA, 2021
In this study, a novel multiple-pollutant waste load allocation (WLA) model for a river system is presented based on the National Sanitation Foundation Water Quality Index (NSFWQI). This study aims to determine the value of the quality index as the objective function integrated into the fuzzy set theory so that it could decrease the uncertainties ...
