Abstract: | Remote sensing provides information on the land surface. Therefore, linkages must be established if these data are to be
used in groundwater and recharge analyses. Keys to this process are the use of remote sensing techniques that provide information
on soil moisture and water-balance models that tie these observations to the recharge. Microwave remote sensing techniques
are used to map the spatial domain of surface soil moisture and to monitor its temporal dynamics, information that cannot
be measured using other techniques. The physical basis of this approach is presented with examples of how microwave remote
sensing is utilized in groundwater recharge and related studies.
