This study investigates the hydraulic behavior of the Kemerdere Aqueduct, an ancient Roman
structure located in the city of Troy, using CFD simulations. It is aim to reveal the engineering
significance of the open channel of the aqueduct, whose flow direction was changed after an
earthquake in antiquity. By analyzing the flow rates and water supply capabilities of the
aqueduct, the research demonstrates its efficiency in providing water to urban populations.
Results reveals that the Kemerdere Aqueduct could supply water to approximately 8,500 to
15,000 people daily, accounting for losses due to leakage and other inefficiencies. This
highlights the advanced engineering skills of Romans and their ability to manage water
resources effectively. Findings emphasize the importance of historical technologies in
addressing contemporary water management challenges and underscore the significance of
preserving ancient engineering marvels. This study contributes to a deeper understanding of
Roman water management practices and their enduring relevance.
