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.
Despite the mechanisms of reservoir sedimentation being well known
for a long time, sustainable and preventive measures are rarely
taken into consideration in the design of new reservoirs. To avoid
operational problems of powerhouses, sedimentation is often treated
for existing reservoirs with measures which are efficient only for
a limited time. The today's challenge of dam owners and engineers
is to guarantee with adequate mitigation measures the future
sustainable use of the vital reservoirs supplying water for
drinking, food and energy production. Research and development is
still urgently needed to identify efficient mitigation measures
adapted to the main sedimentation processes involved in reservoirs.
During the seventh International Conference on Fluvial Hydraulics
"River Flow 2014" at Ecole Polytechnique Federale de Lausanne
(EPFL), Switzerland, scientists and professionals from all over the
world addressed the challenge of reservoir sedimentation in a
special session and exchanged their knowledge and experiences.
Invited and selected contributions, which give an overview on the
latest developments and research regarding reservoir sedimentation
including case studies, are presented in this book, in the hope
that they can contribute to better sustainable use of the vital
reservoirs worldwide.
Dam engineering is currently experiencing a strong revival of
labyrinth oriented weirs. Labyrinth weirs, with a repetitive
constructional character and an increased specific discharge
capacity, are a very good technical-economical compromise. The
concept of Piano Key Weir (PKW), with alveoli developed in
overhangs from a reduced support area, enables the installation of
non-linear crests at the top of concrete dams. As a result it
eliminates the main drawback of classical labyrinth weirs, and
enables their use to rehabilitate numerous existing dams. Since the
first implementation of piano key weirs by Electricite de France on
Goulours dam (France) in 2006, at least eight PKWs have been built
in France, Vietnam and Switzerland. Their operation over a few
years has already provided the first prototype data. Other projects
are under study, construction or planning in varied countries. On
another hand, research programs are under progress all over the
world. Following a first edition in 2011, Labyrinth and Piano Key
Weirs II - PKW 2013 collects up-to-date contributions from people
with various backgrounds, from engineers and researchers to
academics. Summarizing the last developments on labyrinth oriented
weirs, the book constitutes the state-of-the-art in research and
application of piano key weir solutions, and will be invaluable to
professionals and scientists interested in Dams Engineering.
Since the first implementation by Electricite de France on the
Goulours dam (France) in 2006, the Piano Key Weir has become a more
and more applied solution to increase the discharge capacity of
existing spillways. In parallel, several new large dam projects
have been built with such a flood control structure, usually in
combination with gates. Today, more than 25 Piano Key Weirs are in
operation or under construction all over the world. More than 15
years of research and development have enabled detailed
investigations of the hydraulic and structural behaviour of the
Piano Key Weir complex structure and have provided more and more
accurate design equations. Following the proceedings of the first
two workshops held in Liege (Belgium - 2011) and Paris (France -
2013), Labyrinth and Piano Key Weirs III collects the contributions
presented by people with varied background, from researchers to
practitioners, at the 3rd International Workshop on Labyrinth and
Piano Key Weirs - PKW 2017 (22-24 February 2017, Qui Nhon,
Vietnam). The papers, reviewed and accepted by an International
Scientific Committee, summarize the current state-of-the-art on
Piano Key Weirs from a theoretical to a practical point of view,
and present most of the main projects in operation or under
construction. Labyrinth and Piano Key Weirs III is thus a reference
for students, practitioners and researchers interested in Dams
Engineering.

The behaviour of river systems is a result of the complex
interaction between flow, sediments, morphology and habitats.
Furthermore, rivers are often used as a source of water supply and
energy production as well as a waterway for transportation. The
main challenge faced by river engineers today, in collaboration
with environmental and ecological scientists, is to restore the
channelized rivers under the constraints of high urbanization and
limited space, as well as sustainable water use. During the seventh
International Conference on Fluvial Hydraulics "River Flow 2014" at
Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland,
scientists and professionals from all over the world addressed this
challenge and exchanged their knowledge regarding fluvial
hydraulics and river morphology. This book comprises the
proceedings of the high quality contributions of the participants,
which reflect the state-of-the-art in the fields of river
hydrodynamics, morphodynamics, sediment transport, river
engineering and restoration. The conference was organized under the
auspices of the Committee on Fluvial Hydraulics of the
International Association for Hydro-Environment Engineering and
Research (IAHR). Past River Flow conferences have witnessed a
significant increase in participation of our community of river
engineers and researchers, confirming the need for such a forum.
