Concepts on models and similarity are discussed in Chapter 15. The discussion on models includes an example on the Niagara River model, which provides the student with a real-world application of the concepts and that modeling concepts have important practical uses. However, it would have been helpful to have a few more basic examples. The book has many other positive aspects. The index is very complete.
Bold typeface is used to emphasize important concepts.
Most chapters include a brief list of references. Both SI and English units are used. The schematics and figures are easy to read. Overall, Gray s text is a welcome addition to a civil engineering faculty member s bookshelf.
