About
About Wadi Shab Aflaj System
Coastal wadi falaj complex where Aini (spring) and Daudi aflaj emerge from Wadi Shab emerald pools to irrigate 3 villages' terraced mango, lime and palm gardens along Jebel Akhdar wadis dropping to Gulf of Oman. Later Persian Sassanian rebuilding visible. Aflaj tunnels accessible by swimming through submerged passage to hidden waterfall cave — the 'wadi shab cave gap'.
Why it mattersCoastal type of aflaj where spring emerges inside wadi pool cave — unique hydrology.
