Ephemeral river bed in Libya From Wikipedia, the free encyclopedia
Wadi Derna is a river valley in Libya which leads down from the Jebel Akhdar mountains to the port city of Derna. Like many other wadis in North Africa, it is an intermittent riverbed that for much of its length contains water only when heavy rain occurs.[1] It is 75 kilometres (47 mi) long[2] and drains a drainage basin of 575 km2.

The Derna waterfalls are located in Wadi Derna[1] about 7 km (4.3 mi) to the south of Derna.[3]
In September 2023, against the backdrop of the civil war, the rainfall from the Storm Daniel led to the collapse of two dams across the river, the Derna dam and the Abu Mansour dam, causing catastrophic flooding in the city of Derna, which killed at least 4,000 people.[4][5][6] It was one of the deadliest dam failures in history.
