Covers environmental hydraulics and engineering hydrology. This book provides an introduction to the theory of civil engineering hydraulics, together with a number of worked examples and exercise problems with answers.This thorough update of a well-established textbook covers a core subject taught on every civil engineering course. Now expanded to cover environmental hydraulics and engineering hydrology, it has been revised to reflect current practice and course requirements. As previous editions, it includes substantial worked example sections with an on-line solution manual. A strength of the book has always been in its presentation these exercises which has distinguished it from other books on hydraulics, by enabling students to test their understanding of the theory and of the methods of analysis and design. "Civil Engineering Hydraulics" provides a succinct introduction to the theory of civil engineering hydraulics, together with a large number of worked examples and exercise problems with answers. Each chapter includes a worked example section with solutions; a list of recommended reading; and exercise problems with answers to enable students to assess their understanding. The book will be invaluable throughout a student's entire course - but particularly for first and second year study, and will also be welcomed by practising engineers as a concise reference.Preface to Fifth Edition.
