History and context

Masonry wells and galleries captured fossil water by gravity; maintaining them required cooperation, risk and decisions on distribution.

Evidence and interpretation

Synthesis based on ISAC · Archaeology of Fazzan and irrigation landscapes; UNESCO · Rock-Art Sites of Tadrart Acacus. The comparison serves to formulate questions, not to fill gaps in the record with certainties.

Catalogue facts

A valley could irrigate in a different way

The hydraulic synthesis distinguishes Wadi al-Ajal from the depressions of Barjuj, Murzuq and Hofra. In these latter, the terrain configuration was less favourable to foggaras, and the fields were supplied by numerous wells, probably counterpoise, with more limited use of galleries. This difference shows that Garamantian engineering did not consist of reproducing a single system everywhere. Relief, water depth and soil characteristics conditioned the solutions. Comparing wells and tunnels allows understanding local decisions within a connected region.
