Special Issue Information

Dear Colleagues,

Since the dawn of civilization, societies have developed technologies to improve daily life. Today, information technology represents a driving force in societal evolution, fostering accelerated progress and innovation. High-quality water resources are vital to society and rely on emerging technologies and information systems for improving the quality of service and monitoring solutions. Nonetheless, the pursuit of smart water initiatives must harmoniously prioritize both societal well-being and environmental sustainability for developing intelligent environments.

This Special Issue gathers research papers, reviews, and contributions from experts at the intersection of machine learning and environmental science and aims to address the following key inquiries:

  • To what extent can water quality management be facilitated by machine learning techniques?
  • How can intelligent monitoring solutions be integrated in the context of water infrastructure?
  • How can machine learning support high-quality, proactive, and personalized services for humans?

We are pleased to invite you to contribute original research based on machine learning techniques and their applications focused on our most vital resource—water. The primary goal is to provide a comprehensive overview of recent advancements, methodologies, and case studies related to the utilization of machine learning for monitoring and managing water quality, including, but not limited to, the following:

  • Machine learning and deep learning solutions for smart water quality monitoring;
  • The integration of machine learning within smart water infrastructure;
  • Decision support and data-driven solutions for water quality management.

Plastic pollution in the ocean is a severe environmental problem worldwide because rivers carry plastic waste from human activities, harming the ocean’s health, ecosystems, and people. Therefore, monitoring the amount of plastic waste flowing from rivers and streams worldwide is crucial. In response to this issue of river-floating waste, our present research aimed to develop an automated waste measurement method tailored for real rivers. To achieve this, we considered three scenarios: clear visibility, partially submerged waste, and collective mass. We proposed the use of object detection and tracking techniques based on deep learning architectures, specifically the You Only Look Once (YOLOv5) and Simple Online and Realtime Tracking with a Deep Association Metric (DeepSORT). The types of waste classified in this research included cans, cartons, plastic bottles, foams, glasses, papers, and plastics in laboratory flume experiments. Our results demonstrated that the refined YOLOv5, when applied to river-floating waste images, achieved high classification accuracy, with 88% or more for the mean average precision. The floating waste tracking using DeepSORT also attained F1 scores high enough for accurate waste counting. Furthermore, we evaluated the proposed method across the three different scenarios, each achieving an 80% accuracy rate, suggesting its potential applicability in real river environments. These results strongly support the effectiveness of our proposed method, leveraging the two deep learning architectures for detecting and tracking river-floating waste with high accuracy.

Groundwater quality is one of the major concerns. Quality of the groundwater directly impacts human health, growth of plants and vegetables. Due to the severe impacts of inadequate water quality, it is imperative to find a swift and economical solution. Water quality prediction may help us to manage water resources properly. The present study has been carried out considering thirty-seven water sample data points form the Pindrawan tank command area of Raipur district, Chhattisgarh, India. A total of nineteen physicochemical parameters were measured, out of which seventeen parameters were used to compute the weight-based groundwater quality index (WQI). In this present work, the primary goal is to identify the most effective parameters for WQI prediction. Out of the seventeen parameters tested, the Mann—Whitney—Wilcoxon (MWW) statistical test has revealed that five parameters Fe, Cr, Na, Ca, and Mg hold a strong statistical significance in distinguishing between drinkable and non-drinkable water. Out of these five parameters, Cr is the only parameter that maintains a different range of values for drinkable water and non-drinkable water. To validate the efficiency of these statistically significant parameters, machine learning techniques like Artificial Neural Networks (ANN) and Logistic Regression (LR) were used. The experimental results clearly demonstrate that out of all the seventeen parameters tested, utilizing only Cr yields remarkably high classification accuracy. ‘Cr’ achieved an accuracy of 91.67% using artificial neural networks. This is much higher than the accuracy of 66.67% obtained using a parameter set with all seventeen parameters. The proposed methodology achieved good accuracy when classifying water samples into drinkable and non-drinkable water using only one parameter, ‘Cr’. Full article
