Fluid Mechanics and Hydraulics Illustrative Worked Examples of Surface and Subsurface Flows

Fluid Mechanics and Hydraulics: Illustrative Worked Examples of Surface and Subsurface Flows presents the basic principles of fluid mechanics through the use of numerous worked examples. Some readers may have interest only in the application parts of various principles without paying too much attention to the derivation details of equations. Other readers may have interest both in derivation details and their applications. As a result, this book is designed to address both needs, and most derivation details are included as example problems. Therefore, those who are not interested in the details of derivations may skip them without interrupting the effective use of the book. It serves as an effective learning source for college students and as a teaching tool for instructors (with an included solutions manual), as well as for practicing professionals in the areas of fluid mechanics and hydraulics.

He prepared his Associate Professorship thesis in Hydraulic Engineering in 1976-1977 at the University of Wisconsin, Madison. After the submittal of his thesis and passing all required examinations, he was appointed as an Associate Professor (Doçent) in the Department of Civil Engineering of Karadeniz Technical University in June 1979 and he worked as a faculty member until the end of 1982. Finally, he was the Chairman of the Civil Engineering Department. At the end of 1982, he voluntarily resigned from his position and went to the United States of America. He also served as a visiting professor in several universities in the United States and in the United Kingdom and then he joined the private sector in the US and worked on mostly environmental engineering-related projects. In Tűrkiye and the US, he taught many courses both at undergraduate and graduate levels, including hydraulic engineering, open channel hydraulics, hydrology, and ground water hydraulics for over 10 years. Since he received his PhD 1974, Dr. Batu has been involved in many scientific projects and published a number of authored and co-authored papers in some internationally-recognized journals including Ground Water,Journal of Hydrology,Journal of Hydraulic Engineering, Journal of Irrigation and Drainage Engineering,Soil Science Society of America Journal, and Water Resources Research. Dr. Batu has developed new concepts and approaches including many analytical and numerical models in the areas of aquif
