Where Is the Great Zab?
The Great Zab rises in the high mountains of eastern Turkey, near the country of Hakkari, and flows south and west into Iraqi Kurdistan, where it gathers the waters of many tributaries draining the great ranges. It passes through the dramatic gorge country near Rawandiz, flows past the lands south of Deralok, and runs down toward the plains, eventually joining the Tigris below Mosul, not far from the region around Erbil. Its long course ties together the highlands and the lowlands of the Kurdish region.
A River of Gorges
The Great Zab is famous for the spectacular gorges it has carved through the mountains. As it tumbles down from the heights, the river cuts deep canyons through the rock, none more famous than the dramatic chasms of the Rawanduz country, where the water runs far below sheer cliffs. Fed by snowmelt and mountain rain, the Zab can be a raging torrent in spring, and its wild upper reaches, rapids, and green valleys make it one of the most beautiful rivers in the land — a magnet for those who love mountain scenery.
Lifeline of the Land
For the people of the region the Great Zab has always been a lifeline. Its waters irrigate fields and orchards along its valleys, support fishing, and sustain the towns and villages strung along its course. In modern times dams and projects have harnessed parts of the river for water storage and hydroelectric power, while its flow remains vital to the farming of the lowlands downstream. The river’s steady gift of water from the mountains has made settled life possible across a wide and often dry land.
A River of History
The banks of the Great Zab have witnessed momentous events. In ancient times the river ran through the heartland of Assyria, near the great cities of the empire. Its most famous moment came in the year 750, when a decisive battle was fought on the Zab that overthrew one ruling dynasty of the Islamic world and brought another to power — a turning point whose echoes reached across the whole region. Through the centuries the river’s crossings and valleys have shaped the movements of armies, traders, and peoples.
The Great Zab Today
Today the Great Zab remains a powerful presence in the life of Iraqi Kurdistan — a source of water and power, a place of stunning natural beauty, and an increasingly popular destination for those drawn to its gorges and valleys. Like all the rivers of the region it faces the pressures of drought, dams, and changing climate. Yet the Zab flows on as it always has, the great river of the Kurdish mountains, carrying the snows of the heights down to the ancient plains.
