All in all, this book will be valuable to both the practitioner looking for an urgent solution to a site-specific problem and the academic researcher embarking on scour-related research. The authors provide step-by-step guidance with simple formulae and worked examples, as well as in-depth discussions and derivations. The writing style and organisation of the material is easy to follow, the figures are very clear, and the price is inexpensive making it well worth adding to the bookshelf. The serious researcher or practitioner will find it useful to have the earlier books on marine scour as well, since all three have their own strengths. This book leaves no stone unturned--indeed, reading it one wonders what unanswered questions in scour are left for tomorrow's researchers to study.
