Hani (MCSH) system in eastern Tunisia shows that groundwater upwelling and/or seepage
toward the modern surface is important in the shaping of its geomorphologic features and
sediment outcrops. Along the watershed of the system, groundwater is downward enriched
with evaporitic minerals. These minerals precipitate as cement and protect the sediment
outcrops from aeolian erosion. The water table is the limiting control on erosion and …
