ESA Tiger > Results > Ground Water

Satellite observations are limited to the retrieval of surface information, therefore can not be used directly to assess groundwater. However EO-derived information, jointly with in situ observations can be used to identify/estimate parameters (open water extension and dynamics, geological settings and fault lines as potential aquifer recharge areas, crop water consumption, location of wells, precipitation distribution, evapotranspiration, subsidence related to water pumping.) which may support the management of aquifers.
