Novak P. Developments in hydraulic engineering - Vol. 5

Elsevier, 1988г. , 230 стр.

This is the fifth volume of Developments in Hydraulic Engineering, the publication of
which started in the autumn of
1983. During the intervening years one of the main aims
of the series has remained unchanged, i.e. to publish in each volume a number of
chapters considerably more extensive than papers in technical jouals, but shorter than
monographs each giving an authoritative and comprehensive up-to-date review of the
state-of-the-art of a subject area within hydraulic engineering.

The first chapter, on water power development, deals in its first three sections with
some general matters of hydropower utilisation, but the bulk of the text is oriented
towards all aspects of low-head river developments, including their layout, planning
criteria, magnitude and evaluation of producible power and energy, generating sets and
their operation, electrical equipment, environmental aspects and economic appraisal. A
special section on small size hydropower plants is also included. The text is well
documented by figures and contains both the theoretical background as well as practical
advice drawing on the author’s lifelong involvement in hydropower development.
Although some of the material has been published by the author before, it is dispersed in deal of previously unpublished work. The first part of the text forms also an introduction
to a future text by Professor Mosonyi on high-head power development, which is likely
to be included in the next volume.

Developing further the previous treatment of ice engineering, the next chapter, on
intake design for ice conditions, discusses one topic in ice engineering which is of
paramount importance in power development and water supply in general. It deals with
the characteristics of ice problems that must be taken into account in the design and
operation of intakes, the ice growth and production rates and its behaviour at intakes in
various conditions and with the counter measures to be taken. The chapter concludes with
some typical case studies illustrating the magnitude and diversity of the ice conditions at
intakes.

In the third chapter the author discusses the methods of study of the hydraulic behaviour of estuaries, concentrating on the numerical analysis of interactions between estuaries and seas. The detailed treatment of regional modelling of tidal flows and of tidal currents at estuary
mouths, as well as of regional modelling of waves and of nearshore waves and currents,
is followed by the discussion of sea bed stresses and induced sediment transport and a
summary of the properties of various wave models. The chapter concludes with a section
speculating how the previously mentioned three estuaries could be modelled using
recently developed techniques.

The last chapter of this volume looks to one specific development in water resources
engineering of lowlands—the polders. The Dutch engineers have, of course, long been
the pioneers in this area, and three Dutch authors, after a brief description of polders, deal
in some detail with the soil types encountered in polders and particularly with the
complex water management of polders, including design of irrigation and drainage and
flood control systems. The text concludes with a look to the polders of the future.
