The main purpose of this book is to contribute towards an understanding of the specifics of river diversion and to stimulate creativity, when tackling new projects. Many years of activity in hydraulic engineering has taught that the implementation of man-made constructions in natural river valleys should be approached with precision and constraint. Each river diversion project has its own individual character. The diversion structures, and only these, interfere with the changing river: its flow and floods, sediment load and floating debris. A successful design must, therefore, be based on detailed knowledge of the river hydrology. A recent trend in this field is to consider the given river as a system, and to define a conceptual model which embraces the relevant components and their links. Like most major civil engineering undertakings, a river diversion demands extreme precision. Many disciplines are involved: hydrology and hydraulics, soil and structure mechanics, concrete technology, mechanical and electrical engineering. This book pays particular attention to hydraulic design, involving aspects such as layout, structure shape and dimensions, and environmental effects.

Hydraulic engineering of dams and their appurtenant structures counts among the essential tasks to successfully design safe water-retaining reservoirs for hydroelectric power generation, flood retention, and irrigation and water supply demands. In view of climate change, especially dams and reservoirs, among other water infrastructure, will and have to play an even more important role than in the past as part of necessary mitigation and adaptation measures to satisfy vital needs in water supply, renewable energy and food worldwide as expressed in the Sustainable Development Goals of the United Nations. This book deals with the major hydraulic aspects of dam engineering considering recent developments in research and construction, namely overflow, conveyance and dissipations structures of spillways, river diversion facilities during construction, bottom and low-level outlets as well as intake structures. Furthermore, the book covers reservoir sedimentation, impulse waves and dambreak waves, which are relevant topics in view of sustainable and safe operation of reservoirs. The book is richly illustrated with photographs, highlighting the various appurtenant structures of dams addressed in the book chapters, as well as figures and diagrams showing important relations among the governing parameters of a certain phenomenon. An extensive literature review along with an updated bibliography complete this book.

Side weirs are widely used to divert or discharge flows from reservoirs, rivers, artificial channels and sewers. The hydraulic behaviour of this type of weir is complex and difficult to predict accurately using simple methods and the diversity of applictions of side weirs has the potential to complicate guidance. This manual covers the fundamental hydraulic principles and discusses the practical design issues separately for each main strcuture type.
