Human settlement in Yemen
At the mouth it carries 0.4 m³/s on average: an Olympic pool every 6,173 seconds. It drops from 1,369 m to 874 m, 8.6 m per kilometre on average. Its basin covers 2,435 km², about the size of RE. 35,000 people live in it. Highest water: from March to April; lowest: from June to July and from October to November. No large dam holds it back: it is one of the world's free-flowing rivers.

Wadi Dawan, month by month
Highest water: from March to April
Lowest water: from June to July and from October to November. Best months to visit: from January to May.
From about 0.0 m³/s in the lowest month to 1.9 m³/s in the highest. An estimate: the monthly flow is modelled from the lowest and highest months of WaterGAP (RiverATLAS, 1971–2000) and the rain and snow along the river (WorldClim). Dams change the real rhythm. The chip is the average air temperature; below it, the month's rain.
