Oum Er-Rbia River

The second one in Top 10 Longest Rivers in Morocco that Toplist would like to introduce to you is Oum Er-Rbia River. The Oum Er-Rbia River is a large, long, and high-flowing river in central Morocco. The river runs for 555 kilometers (345 miles).Oum Er-Rbia is the second longest river in Morocco, after the Sebou River, with an average water throughput of 105 m3/s. It begins in the Middle Atlas and flows through the city of Khénifra before reaching the Atlantic Ocean at the port of Azemmour on its left bank. The most important dam in Oum Er-Rbia is the Al Massira Dam. El-Abid River, Tessaoute River, and Lakhdar River are its most important tributaries.

The river's historical Berber nickname was Asif n Isaffen, which means "river of rivers." Scholars believe that the river's original Berber common name, Wansifen, was only recently changed, around the 16th or 17th century, and that a nearby village called Oum Rabia may have influenced this change.

A large number of groundwater springs feed Oum Er-Rbia. As a result, the area near its headwaters is known as "The Forty Springs," though this is a poetic term rather than an exact count.
