  abstract = {{T}he oases in the arid the {N}efzaoua region in central-western {T}unisia are associated with spring mounds. {S}pring mounds result from an exceptional succession of geomorphological, hydrogeological and climatic conditions and processes that follow each other in a specific order. {T}hey look like small volcanoes that range from 200 m to more than 2000 m in diameter and 3-30 m in height, which centres were once occupied by a pond fed by an artesian spring. {T}hey are at the origin of each oasis's irrigation system, which radiates from the mound's foot. {D}ue to intense irrigation of intensive date palm plantations ({P}hoenix dactylifera) in recent decades, all artesian springs dried out. {W}e established a complete inventory and typology (i.e. location, dimension, and types of degradation) of all spring mounds in the {N}efzaoua region. {O}verall, in an area of 3000 km2, 126 spring mounds of 7 types were identified, of which 112 (89%) were degraded. {D}ue to the low salt content in spring mound sediments, they are excavated and used as a soil amendment to expand new palm plantations. {O}nly 14 mounds (11%) are presently preserved. {T}heir qualification as a geomorphosite could preserve them from complete destruction.},
