Special Issue Information

Dear Colleagues,

We are excited to invite submissions to a Special Issue titled “New World: Advancing Water Applications Through Machine Learning and Artificial Intelligence”. This Special Issue focuses on the transformative potential of machine learning (ML) and artificial intelligence (AI) technologies in addressing complex water-related challenges. It seeks original research and case studies demonstrating how ML and AI can enhance water-related fields, including the development of predictive models for the supply and demand of water, the application of deep learning for real-time water quality assessments, and the use of AI in smart water networks for efficient resource allocation. This Special Issue serves as a platform for researchers, practitioners, and policymakers to share insights and will foster collaboration to advance the sustainable management of water resources through AI and ML innovations‌. We encourage the submission of original research articles, reviews, and case studies that demonstrate how the application of machine learning and artificial intelligence technologies can solve complex water-related problems.

Algal blooms pose significant risks to public health and aquatic ecosystems, highlighting the need for real-time water quality monitoring. Traditional manual methods are often limited by delays in data collection, which can hinder timely response and effective management. This study proposes a solution by integrating automated monitoring systems (AMSs) with advanced machine learning (ML) techniques to predict chlorophyll-a (Chla) concentrations. Utilizing low-cost and readily available input variables, we developed energy-efficient ML algorithms optimized for deployment on buoys with a battery and hardware resources. The AMS employs preprocessing methods like the SMOTE and Random Forest (RF) for feature selection and ranking. Deep feature extraction is performed through a ResNet-18 model, while temporal dependencies are captured using a Long Short-Term Memory (LSTM) network. A Softmax output layer then predicts Chla concentrations. An alert system is incorporated to warn when Chla levels exceed 10 μg/L, signaling potential bloom conditions. The results show that this approach offers a rapid, cost-effective, and scalable solution for real-time water quality monitoring, enhancing manual sampling efforts and improving management of water bodies at risk.
