Study Regions

Study Regions


One of GRAPHIC’s goals is to establish studies in different countries and regions of the world that incorporate a similar philosophy and approach – to analyze groundwater sustainability under the impacts of human activities and climate change and identify adaptation strategies. Findings from the studies will likely provide insights and comparisons among similar countries/regions, creating a global network of groundwater projects. By encouraging and coordinating consistent regional efforts provides a means to achieve GRAPHIC objectives while broadening the impact and applicability of the program.

GRAPHIC studies in different physiographic, climatic, and water use/management settings around the world will provide an opportunity to compare data among areas, and evaluate how controlling factors influence local water quantity and quality. GRAPHIC studies are designed around aquifers rather than political boundaries. GRAPHIC also provides opportunities for nested studies that address both sub-regional variations and primary controlling processes that enable up- and downscaling of interpretations.

At present, GRAPHIC regional expert groups have been established in the following regions:

Case Studies

The GRAPHIC network currently includes more than 20 case studies from parts of 30 countries. These case studies address groundwater resources in a range of hydrogeological settings from mountainous to coastal aquifer systems, including unconfined, semi-confined, and confined aquifers in unconsolidated to fractured- rock material.

GRAPHIC case studies include several high profile aquifer systems from each of the regions, including:
