Location and morphological status of spring mounds in the Nefzaoua Province in western Tunisia in 2020.

Overall, in an area of 3 000 km2, 126 spring mounds of 7 types were identified, of which 112 (89%) were degraded. Due to the low salt content in spring mound sediments, they are excavated and used as a soil amendment to expand new palm plantations.

Only 14 mounds (11%) are presently preserved. We used old topographical maps, aerial photographs, TanDEM-X digital elevation model (DEM) and information from Google Earth to create this dataset.
