Special Issue Information

Dear Colleagues,

Artificial intelligence will play a critical role in international efforts to mitigate climate change’s impacts on the environment and preserve water resources.

Due to the combined effects of climate change and human activity in recent years, traditional methods in the fields of hydrology and water resources may not be sufficient to provide satisfactory results for practical engineering problems. Therefore, more focus has been placed on cutting-edge AI techniques in water resource management, leading to an increase in global research output. Specifically, AI has a great deal of potential for groundwater management in the future.

With the ability to provide accurate predictive modeling, real-time monitoring, and data integration, artificial intelligence (AI) is set to revolutionize groundwater management practices.

Several sophisticated artificial intelligence techniques, such as artificial neural networks, support vector machines, deep learning machines, Bayesian networks, Markov models, Kalman filters, chaos theory, and Gaussian process regression, have been successfully developed in recent decades to improve the understanding or simulation of the complex hydrodynamic processes found in nature. Generally speaking, by gaining important knowledge from a vast number of data samples, artificial intelligence techniques can accurately simulate the nonlinear relationship between the input and output variables.

Artificial intelligence (AI) techniques can be applied for the simultaneous prediction of groundwater heads, contaminant transport, and saltwater intrusion; the optimization of monitoring networks; and providing early warnings of critical conditions pertaining to the supply of drinking water and ecosystems that depend on groundwater. As AI techniques can transfer data spatially and temporally, they can extract complex relationships from existing data and offer significant advantages over established techniques. More sophisticated AI models can produce more accurate predictions of groundwater behavior, pinpoint areas susceptible to pollution and depletion, initiate preventive actions, and promote platforms for cooperation between local communities, policymakers, and scientists.

This Special Issue examines the multifaceted applications of AI in this field, breaking down its contributions, tackling related issues, and outlining its potential future applications.

It is still essential for resilient and sustainable groundwater management techniques to embrace AI's potential while tackling its obstacles. AI has the potential to develop a more resilient and sustainable groundwater management paradigm by overcoming obstacles through interdisciplinary collaboration and capacity-building. However, more research, policy integration, and technological innovation are required to harness the full power of AI to protect this invaluable resource.

Groundwater salinization poses a critical threat to sustainable development in arid and semi-arid rurbanizing regions, exemplified by Kerman Province, Iran. This region experiences groundwater ecosystem degradation as a result of the rapid conversion of rural agricultural land to urban areas under chronic drought conditions. This study aims to enhance Groundwater Pollution Risk (GwPR) mapping by integrating the DRASTIC index with machine learning (ML) models, including Random Forest (RF), Boosted Regression Trees (BRT), Generalized Linear Model (GLM), Support Vector Machine (SVM), and Multivariate Adaptive Regression Splines (MARS), alongside hydrogeochemical investigations, to promote sustainable water management in Kerman Province. The RF model achieved the highest accuracy with an Area Under the Curve (AUC) of 0.995 in predicting GwPR, outperforming BRT (0.988), SVM (0.977), MARS (0.951), and GLM (0.887). The RF-based map identified new high-vulnerability zones in the northeast and northwest and showed an expanded moderate vulnerability zone, covering 48.46% of the study area. Analysis revealed exceedances of WHO standards for total hardness (TH), sodium, sulfates, chlorides, and electrical conductivity (EC) in these high-vulnerability areas, indicating contamination from mineralized aquifers and unsustainable agricultural practices. The findings underscore the RF model’s effectiveness in groundwater prediction and highlight the need for stricter monitoring and management, including regulating groundwater extraction and improving water use efficiency in riverine aquifers.
