In this study, remote sensing data and spatial analysis techniques were used to study the validity and efficiency of groundwater in 45 wells. The study area included the Baghdad-Karbala Road, passing through the Jurf al-Sakhar district, extending over a distance of more than 80 kilometres (50 miles). The road begins from the city of Latifiya, where it connects with al-Qamishli Street at the Jurf al-Sakhar bridge in the village of al-Fadhiliya, to cross the city of Jurf al-Sakhar longitudinally, passing through the villages. agricultural areas, reaching the Al-Khanafsa and Al-Jamaliyya area, then to Karbala Governorate. Well locations were determined using Global Positioning System (GPS) and this data was processed and georeferenced to represent actual locations on satellite images. The Sentinel-2 satellite was used to capture images and were processed using ArcMap 10.6 software. The depths of the wells were studied and spatial analysis maps were produced based on the spatial extrapolation technique provided by the program. The results showed that the depths of the selected wells were within international standards and Iraqi standards, as the depth in Karbala reached 280 meters, while in Baghdad it reached 84 meters. The wells in the Baghdad Governorate formation were more productive than the wells near the administrative borders of the Karbala Governorate, as the highest production value reached 864 m3/day in the city of Latifiyah, while the highest value in the wells of the Al-Fadhiliya village reached 432 m3/day. day. day.
