Hydraulic Principles and Design Concepts for Submain Units with Multiple Outlet Pipelines

Gürol Yıldırım is full Professor of Civil Engineering, Head of Hydraulics Division, Civil Engineering Department, and Vice Rector of Giresun University, Turkey. Born in Konya, Turkey, he received Ph.D. degree from Hydraulic Engineering Division at Istanbul Technical University, Civil Engineering Faculty, in 2007. During his doctorate at Istanbul Technical University, he taught courses in fluid mechanics, hydraulics, water resources, hydrology, water supply and environmental sanitation; river hydraulics and restoration, flood control and its hydrology, manifold and diffuser hydraulics in water distribution networks. He has been at Texas A&M University (TAMU) Biological and Agricultural Engineering Department (BAEN) for post-doctorate research and joined in colloborative projects with Dr. Vijay P. Singh.. Dr. Yıldırım received associate professorship degree in 2011, and professorship degree in 2016, in Civil and Hydraulic Engineering Department. His researches is mainly conducted on the hydraulic and economic analysis and design concepts on water distribution networks, pipe flows hydraulics analysis i.e. low-volume and low-pressurized irrigation systems, , turbulent and resistance law phenomena pipe turbulent flows, friction factor computation methods using truly analytical, numerical and semi-theoretical approaches and new soft-computing techniques, and commercial pipeline design. He has published full-paper technical articles, technical notes, discussions and closures, more than 100, in respective publishers; reviewed numerous technical papers, published book chapters, technical reports in several major projects.  Dr. Yıldırım has received “the Best Discussion Award”, from American Society of Civil Engineers (ASCE) at the Environmental Water Resources Institute (EWRI) Conference, in Honolulu/Hawaii, 2008. He is a member of the American Society of Civil Engineers (ASCE) and also  Member of Science and Advisory Board of the Journal of Environment, Urban and Climate, published under the Republic of Turkey, Ministry of Environment, Urbanization and Climate Change. He lives with his wife Semra, his daughter Mihrimah Ruveyda, and his son Mücahit in Giresun/Turkey.
