The longest River

Sebou River, important river in northern
Morocco, draining part of the
Atlas Mountains and the
Gharb coastal plain into the
Atlantic Ocean. From its source as the Guigou River in the
Middle Atlas (Moyen Atlas), it flows northward to
Fès and then eastward to the Atlantic at Mehdiya—a distance of 280 miles (450 km). The
Kenitra, 10 miles (16 km) upstream from Mehdiya, is a busy port at the head of navigation for oceangoing vessels. Tributaries of the Sebou include the Rdom River, which is the location of a thermal generating station (at Sidi Qacem), and the Beth River, site of a hydroelectric plant (at El-Kansera). Other tributaries are the Ouergha and Inaouene rivers.
Sebou basin is a major olive, rice, wheat, sugar beet, citrus, and grape region.
