Willi H. Hager Books

Focusing on hydraulic jumps and stilling basins, this book compiles extensive research and insights on energy dissipation in hydraulic engineering. It traces the historical context from da Vinci's initial description to modern design advancements. The text reviews numerous papers, discusses current trends, and outlines future research directions. While providing design criteria and recommendations, it emphasizes the complexity of creating effective stilling basins. The book is divided into two parts, covering hydraulic jumps and various hydraulic structures, with consistent notation and references throughout.

Focusing on the theory and computation of open channel flows, this book rigorously derives fundamental equations through vertical integration of the RANS equations for turbulent flow. It critically examines the hydrostatic pressure hypothesis central to shallow water hydraulic models. Emphasizing one-dimensional models, it covers both unsteady and steady flows, detailing modern shock capturing finite difference and finite volume methods. The quality of solutions is thoroughly evaluated against analytical and experimental results, making it a comprehensive resource for understanding open channel hydraulics.

Focusing on wastewater hydraulics, this comprehensive reference integrates new insights for both researchers and practicing engineers. It serves as a valuable textbook for graduate students while maintaining reference book qualities. Each chapter begins with a summary and includes practical examples to clarify computational procedures. The text also highlights historical milestones in hydraulics, providing context for current knowledge. Definitions of terms are clearly presented, and references at the end of each chapter offer avenues for further exploration.

This book is not only a reference for researchers but also a basis for practising engineers. It can be used as a text book for graduate students, although it has the characteristics of a reference book. It addresses mainly the sewer hydraulician who has to tackle many a problem in daily life, and who will not always find an appropriate solution. Each chapter is introduced with a summary to outline the contents. To illustrate application of the theory, examples are presented to explain the computational procedures. Further, to relate present knowledge to the history of hydraulics, some key dates on noteworthy hydraulicians are quoted. A historical note on the development of wastewater hydraulics is also added. References are given at the end of each chapter, and they are often helpful starting points for further reading. Each notation is defined when introduced, and listed alphabetically at the end of each chapter.
