The Oued Sebou is Morocco's largest river by discharge volume, playing a pivotal role in the nation's economy and geography. Originating in the Middle Atlas Mountains as the Oued Guigou, it flows for approximately 450 kilometers across the country. The river traverses the fertile Gharb Plain, one of Morocco's primary agricultural regions, before emptying into the Atlantic Ocean at Mehdia, near Kenitra. Its drainage basin covers roughly 40,000 square kilometers, which accounts for about 6% of Morocco's total land area. The Sebou is essential for the large-scale irrigation of cereals, citrus fruits, and rice paddies. Due to its significant water volume, it feeds several major dams, most notably the Al Wahda Dam, the second-largest dam in Africa. Historically, the Sebou basin has been a center of Moroccan civilization, supporting major cities like Fez along its tributaries. Currently, the river faces environmental challenges due to industrial runoff and urban waste, leading to extensive national restoration efforts.
