This comprehensive handbook on the hydraulic design of labyrinth
spillways - from theory to current practice - presents a
state-of-the-art method for the effective design of labyrinth weirs. The
book first provides a fundamental understanding of the theory of
labyrinth weirs and continues with detailed sections on significant
factors that affect the discharge characteristics of labyrinth weirs
such as crest shape, weir height, and sidewall angle. The most common
design curves are discussed, and from these a recommendation is
developed for only one design curve to be used in future designs. But
because site conditions often vary so much from the idealized conditions
described in this book, a section on site-specific modeling criteria is
included for making accurate predictions of prototype performance. In
its review of past studies, the book closely examines many long held
concepts, especially concerning the idea of interference, nappe
oscillation, and the definition of which head to use in design
computations, and revises them in an effort to advance current thinking
based on the latest research. With its review of theoretical concepts
and its straightforward presentation of the practical aspects of design,
both practicing engineers and researchers will find this book to be a
"must-have" reference for the hydraulic design of labyrinth weirs. The
chapters include: Analytic Development; Nappe Interference; Crest
Shapes; Design Curves; Downstream Chute; Nappe Oscillation; Design;
Sedimentation and Ice; Aeration; Special Cases; and Model Studies. To
help guide the designer, an appendix provides a representative sample of
the prototype installations and their dimensions that have been
constructed worldwide.
