Why did Turkey dam the Tigris river?

Turkey dammed the Tigris River primarily as part of the Southeastern Anatolia Project (GAP), aiming to enhance water management, irrigation, and hydroelectric power generation in the region. The dams help regulate water flow and support agricultural development, which is vital for Turkey's economy. However, this has raised concerns among downstream countries, particularly Iraq, about water shortages and environmental impacts. The project reflects Turkey's strategy to control its water resources amidst regional geopolitical dynamics.
