Interactive Map

This dataset shows the degree of groundwater development as a percentage of estimated recharge and the main groundwater use for global groundwater regions.

Map description and dataset provided by: International Groundwater Resources Assessment Centre (IGRAC)

DescriptionGroundwater Development

Names for the regions are associated with the most pronounced geomorphologic features and relative geographical location on the particular continent. Regionally accepted names, appearing the in the continental geographical references, are used. A total of 36 groundwater regions is used.

Interpretation

Basic to the concept of groundwater region is the assumption that large-sized territories have a certain groundwater setting that is contrasting with the neighboring regions. The purpose of a division into groundwater regions is to organize the complexity of global groundwater occurrence into simple pattern and provide practical framework for an overview of groundwater resources.

Background

Delineation of groundwater regions is primarily based on general geographical references and the USGS classification of geological provinces related to the wolrd energy resources. Im some cases, existing divisions into hydrogeological regions are used.
