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. La télédétection fournit des informations sur la surface du sol. C'est pourquoi des liens doivent être établis lorsque ces données sont utilisées dans l'étude des eaux souterraines et de leur recharge. Les clés de cette démarche sont l'utilisation des techniques de télédétection qui informent sur l'humidité du sol et les modèles de bilan hydrologique qui associent ces observations à la recharge. Les techniques de télédétection dans le domaine des micro-ondes sont mises en œuvre pour cartographier l'humidité du sol en surface dans l'espace et pour suivre sa dynamique dans le temps, informations qui ne peuvent pas être obtenues par d'autres techniques. La base physique de cette approche est présentée avec des exemples d'utilisation de la télédétection micro-onde pour la recharge de nappes et dans les études associées. La teledetección proporciona información de la superficie terrestre. Por ello, se debe establecer vínculos si se pretende utilizar dichos datos para análisis de aguas subterráneas y recarga. Son factores clave en este proceso el uso de técnicas de teledetección para recoger información sobre la humedad del suelo y los modelos de balance de agua que ligan estas observaciones con la recarga. Las técnicas de teledetección por microondas se emplean con el fin de cartografiar el dominio espacial de la humedad superficial del suelo y controlar su dinámica temporal, cosa que no se puede lograr con otros medios. Se presenta el fundamento físico de este enfoque mediante ejemplos de cómo la teledetección por microondas es aplicada en estudios de recarga y trabajos relacionados.
