Al-Marsad Newspaper: Weather expert Dr. Khaled Al-Zaaq explained: “Wadi Al-Rumma is the greatest, longest and most famous valley in the Arabian Peninsula, and it is the only one that cuts it from west to east, indicating that Wadi Al-Rumma is one of the natural phenomena in the Kingdom.
He said, during a video clip he posted on his official account on Twitter: “In rainy times, it was a river running from the heights of the Hijaz to the Shatt al-Arab, and in the era of desertification, sand cut its limbs, turning it into 3 parts: Wadi al-Rama, Wadi al-Ajrdi, and Wadi al-Batin.”
He continued: “In the era of drought, it turned into a dry river that rises three times every year, and with climate changes, it began to run at close intervals.”
