Althwairat and Dahna led to the course of the valley being cut into three parts: Wadi al-Rummah (the longest, at 600 km (370 mi)), Wadi Aloddi (45 km (28 mi)), and Wadi al-Batin (450 km (280 mi)). Geological studies show that Wadi al-Rummah flows at full capacity about three times every 100 years. It flowed most recently in 1945, 1982, 1987, 2004, 2008 and 2018. In 1818, the river valley was flooded for 40 days, in 1838 for 22 days, in 1987 and 2008 for 17 days. In 1838 the wadi overflowed, creating a 200-square-mile (520 km) lake that persisted for two years and attracted water birds which had rarely been seen in the valley.

He called it the Kuwait River, which is more popularly known as Wadi Al-Batin, an extension of Wadi Al-Rummah. The Wadi Al-Batin river system would have been responsible for deposition of the Dib DiBa
Formation (similar to an alluvial fan deposit, both morphologically and sedimentologically). This

Farouk El-Baz piqued the interest of
Biblical scholars around the world with his announcement of paleo-drainage from Arabian Peninsula into the Persian Gulf. The idea that a river once flowed across the deserts of Arabia, and somehow connected with the Tigris and/or Euphrates Rivers, draws its
