The hydraulic performance of traditional labyrinth weirs has been extensively studied in the literature. The research outcomes indicated that labyrinth weirs have many hydraulic advantages to pass more flow with a constant water head which reduces the construction cost and improve flood prevention. In this study, a series of laboratory experiments was conducted to test a new weir design based on a classical triangular labyrinth weir. A square pool was added to the vertex of a triangular labyrinth weir in two different directions to form two new designs named as labyrinth weirs with upstream and downstream pools. Detailed velocity and turbulence measurements were conducted using an Acoustic Doppler Velocimetry (ADV) probe to investigate the flow dynamics and turbulence characteristics of the new design in both free and submerged flow conditions. The ability of using a series of the newly design weirs as a fish passage was tested by constructing a series of weirs with different weir spacing. The upstream flow velocities in three directions and the mean and the turbulent kinetic energies (TKE) were measured with the ADV probe. The mean velocity and the turbulent kinetic energy distribution indicated that the maximum range occurred in the corner of the main sidewall of the weir and the pool's sidewalls. The maximum longitudinal and vertical velocities and TKE for the weir with the upstream pool occurred inside the pool, whereas the maximum lateral velocity located in the vicinity of the main sidewall of the weir. In addition, the lateral velocity in the labyrinth weir with the upstream pool changed to the elevation equal to 70% of the upstream water level.

Recent advances in technology have permitted the construction of large dams, reservoirs and channels. This progress has necessitated the development of new design and construction techniques, particularly with the provision of adequate flood release facilities. Chutes and spillways are designed to spill large water discharges over a hydraulic struc

Many fish species, like salmon and sturgeon, undertake extended migrations as part of their basic behavior, and other fish and invertebrates also undertake short-term or small-scale migrations at certain phases of their life cycles. Activities such as dam construction for water supply and power generation, channelization for navigation and flood control, land drainage and wetland reclamation for agricultural and urban use all have profound impact on the aquatic ecosystem and thus on natural fish populations. Fish passes are often the only way to make it possible for aquatic fauna to pass obstacles that block their up-river journey. Based on knowledge and experience from mainly Europe and North America, this book describes the various types of fish passes, with special emphasis to "close-to-nature" solutions.

This book discusses in detail the planning, design, construction and management of hydraulic structures, covering dams, spillways, tunnels, cut slopes, sluices, water intake and measuring works, ship locks and lifts, as well as fish ways. Particular attention is paid to considerations concerning the environment, hydrology, geology and materials etc. in the planning and design of hydraulic projects. It also considers the type selection, profile configuration, stress/stability calibration and engineering countermeasures, flood releasing arrangements and scouring protection, operation and maintenance etc. for a variety of specific hydraulic structures. The book is primarily intended for engineers, undergraduate and graduate students in the field of civil and hydraulic engineering who are faced with the challenges of extending our understanding of hydraulic structures ranging from traditional to groundbreaking, as well as designing, constructing and managing safe, durable hydraulic structures that are economical and environmentally friendly.

Labyrinth spillways are almost as old as dam engineering. In spite of the fact that they appear as a very good technical-economical compromise, only 0.1% of large dams are equipped with such weirs. The main reason for this is that traditional labyrinth weirs usually cannot be installed on top of concrete gravity dams as they require a large foundat

The Hydraulics of Open Channel Flow is a major new textbook for senior undergraduates and postgraduate students. Dr Chanson first introduces the basic principles of open channel flow hydraulics, namely the continuity, Bernoulli and momentum principles. Applications include short transitions (e.g. intake), hydraulic jumps and flow resistance. The key topics of sediment transport, hydraulic modelling and the design of hydraulic structures are then developed in turn. This innovative textbook contains numerous examples, including practical applications, and is fully illustrated with line drawings and photographs in colour and black and white. Exercises - located at the end of each chapter and as revision sections at the end of each part - form an integral part of the text. The book concludes with major assignments, which assimilate all the knowledge into a fully coherent whole. Solutions to exercises, together with the shareware software Hydroculv, are available from the Web at: Key Features: Ideal for Use by Students and Lecturers in Civil and Environmental Engineering Numerous Exercises and Examples, Including a Supporting Website, to Aid the Reader’s Understanding Comprehensive Coverage of the Basic Principles and the Key Application Areas of the Hydraulics of Open Channel Flow the Reader is Taken Step by Step from the Basic Principles to the More Advanced Design Calculations
