Beneath the surface of global change: Impacts of climate change on groundwater

Journal of …, 2011

Global change encompasses changes in the characteristics of inter-related climate variables in space and time, and derived changes in terrestrial processes, including human activities that affect the environment. As such, projected global change includes groundwater systems. Here, groundwater is defined as all subsurface water including soil water, deeper vadose zone water, and unconfined and confined aquifer waters. Potential effects of climate change combined with land and water management on surface waters have been studied in some detail. Equivalent studies of groundwater systems have lagged behind these advances, but research and broader interest in projected climate effects on groundwater have been accelerating in recent years. In this paper, we provide an overview and synthesis of the key aspects of subsurface hydrology, including water quantity and quality, related to global change.

2008-Climate change and groundwater: a short review. By W. Dragoni and B. S. Sukhija

Geological Society, London, Special …, 2008

There is a general consensus that climate change is an ongoing phenomenon. This will inevitably bring about numerous environmental problems, including alterations to the hydrological cycle, which is already heavily influenced by anthropogenic activity. The available climate scenarios indicate areas where rainfall may increase or diminish, but the final outcome with respect to man and environment will, generally, be detrimental. Groundwater will be vital to alleviate some of the worst drought situations. The paper analyses the main methods for studying the relationships between climate change and groundwater, and presents the main areas in which hydrogeological research should focus in order to mitigate the likely impacts.

An Overview of the Potential Impacts of Climate Change on Groundwater Resources

Journal of Informatics and Mathematical Sciences, 2017

Climate change has been consistently observed over the past decades to be associated with changes and/or modifications of components of the hydrological systems. Observational records and global and regional climate projections indicate that both surface-water and groundwater resources are vulnerable to climate change and variability. Thus, understanding the impacts of climate change and variability on groundwater systems is integral to better planning and efficient management of groundwater resources. However, assessing and predicting the effects of climate change on groundwater systems is relatively difficult due to the uncertainties associated with the spatial and temporal prediction of future climates. This review provides an overview of the key components of groundwater hydrology in relation to climate change. The effects of changes in climate on groundwater in soil, deep vadose and saturated zones are assessed. The responses of groundwater recharge, discharge, quality and chan...

Impact of Climate Change on Groundwater Resources - Status of Research Studies

Climate change poses uncertainties to the supply and management of water resources. The Intergovernmental Panel on Climate Change (IPCC) estimates that the global mean surface temperature has increased 0.6 ± 0.2 o C since 1861, and predicts an increase of 2 to 4 o C over the next 100 years. Temperature increases also affect the hydrologic cycle by directly increasing evaporation of available surface water and vegetation transpiration. While climate change affects surface water resources directly through changes in the major long-term climate variables such as air temperature, precipitation, and evapotranspiration, the relationship between the changing climate variables and groundwater is more complicated and poorly understood. The greater variability in rainfall could mean more frequent and prolonged periods of high or low groundwater levels, and saline intrusion in coastal aquifers due to sea level rise and resource reduction. Groundwater resources are related to climate change through the direct interaction with surface water resources, such as lakes and rivers, and indirectly through the recharge process.

Climate change and its influence on groundwater resources

Climate change is commonly discussed at national and international levels. It directly affects the water cycle and thus life on Earth. The effect of climate change on surface water has been known for quite sometime now, however research is still in its infancy on the effects of climate change on the subsurface water. This review provides an insight into the factors responsible for climate change, its effects on groundwater quantity and quality on a global scale with emphasis on Indian groundwater resources and anticipated mitigation strategies
