Presenting the development process of Türkiye’s water structures and engineering history through the lens of a civil engineer, this work documents Mustafa Kafalıer’s sixty years of professional experience across the axis of dam projects. Covering a wide spectrum ranging from global-scale mega-projects like the Atatürk Dam to irrigation and flood control systems that serve as the key to local development, the book blends technical data with the social and professional atmosphere of the period. Enriching the narrative of how Türkiye’s water resource management and engineering vision were shaped with human and technical stories, this work serves as both an inspiring sharing of experience and a valuable historical guide for young engineers and industry professionals alike.
