Hajar

Wadi Hajar cuts through southwestern Hadhramawt toward the Arabian Sea. Unlike many Arabian wadis, the Hajar carries water throughout the year, supporting cultivated land along its valley. Its waters form a separate system from Wadi Hadhramawt farther inland. Irrigation works in this part of Hadhramawt have roots in the pre-Islamic era, testifying to the long use of the region's scarce water.
