Hydraulic Structures Fourth Edition

Abstract

The aim of the book, to provide a text for final year undergraduate and postgraduate students, remains the same as in the previous editions; we also trust that researchers, designers and operators of hydraulic structures will continue to find the text of interest and a stimulating up-to-date reference source. This new edition enabled us to update the text and references throughout, and to introduce some important changes and additions reacting to new developments in the field. We have also taken note of some comments received on the previous edition; particular thanks for the constructive comments and help provided by Professor J. Lewin in redrafting Chapter 6 (Gates and valves). The authorship of individual chapters remains the same as in previous editions; (Dr Narayanan carried out the work on this edition during his stay in the Faculty of Civil Engineering, Universiti Teknologi Malaysia, Johor Bahru, Malaysia). However, as our colleague Dr C. Nalluri unfortunately died in December 2003 ‘his’ text was reviewed by Dr Narayanan (Chapter 13) and Professor Novak (Chapters 9, 10 and 12) who also again edited the whole text. Readers of the previous (2001) edition may note the following major changes: Chapter 1. Enhanced discussion of environmental issues including the World Commission on Dams report. Chapter 2. New sections on partially saturated soils, small farm and amenity dams, tailing dams and lagoons and upgrading and rehabilitation of embankment dams; extended treatment of upstream face protection/rock armouring. Chapter 3. Extended discussion of roller-compacted concrete dams and a new section on upgrading of maso
