Special Issue Information

Dear Colleagues,

Climate change can lead to variability in precipitation and more extreme weather events, can cause sea-level rise, storm surges and seawater inundation, longer periods of droughts and floods, which can all directly or indirectly affect the availability and dependency on groundwater. Groundwater is an important source of drinking water, agricultural production, and heavily used in some commercial industrial setups. It is critically important for us to investigate, explore and understand how climate change will affect the quality and quantity of groundwater.

Studying the relationship between climate change and groundwater is important because it can help us understand how to manage and protect our groundwater resources in a changing climate. By understanding how changes in precipitation and temperature patterns impact groundwater, how sea-level rise, storm surges and seawater inundation impacts aquifer systems and groundwater resources, we can develop more effective strategies for water resource management and conservation. This knowledge can also help us predict and adapt to future changes in water availability and quality.

The main aim of this Special Issue is to initiate discussions, explore ideas, focus on collaborations, and share concepts that will help us design and implement effective groundwater monitoring and management strategies and prepare for tomorrows changing climate.

Abstract
The Earth’s water resources, totalling 1.386 billion cubic kilometres, predominantly consist of saltwater in oceans. Groundwater plays a pivotal role, with 99% of usable freshwater supporting 1.5–3 billion people as a drinking water source and 60–70% for irrigation. Climate change, with temperature increases [...] Read more.
The Earth’s water resources, totalling 1.386 billion cubic kilometres, predominantly consist of saltwater in oceans. Groundwater plays a pivotal role, with 99% of usable freshwater supporting 1.5–3 billion people as a drinking water source and 60–70% for irrigation. Climate change, with temperature increases and altered precipitation patterns, directly impacts groundwater systems, affecting recharge, discharge, and temperature. Hydrological models are crucial for assessing climate change effects on groundwater, aiding in management decisions. Advanced hydrological models, incorporating data assimilation and improved process representation, contribute to understanding complex systems. Recent studies employ numerical models to assess climate change impacts on groundwater recharge that could help in the management of groundwater. Groundwater vulnerability assessments vary with the spatial and temporal considerations, as well as assumptions in modelling groundwater susceptibility. This review assesses the vulnerability of groundwater to climate change and stresses the importance of accurate assessments for sustainable water resource management. It highlights challenges in assumptions related to soil and aquifer properties, multiple stressors, adaptive capacity, topography and groundwater contamination processes, gradual sea level rise scenarios, and realistic representations of the region of study. With the advancements in hydrological modelling, including the integration of uncertainty quantification and remote sensing data, artificial intelligence could assist in the efforts to improve models for assessing the impacts of climate change on hydrological modelling.
