Based on geological and hydrogeological information, the data can be used to identify areas where where groundwater may come close to the ground surface and where geological conditions could enable groundwater flooding to occur.

Groundwater flooding happens in response to a combination of already high groundwater levels (usually during mid or late winter) and intense or unusually lengthy storm events. Groundwater flooding often lasts much longer than flooding caused by a river overflowing its banks. It may last many months and can cause significant social and economic disruption to the affected areas.
