Introduction to Hydrology

I suppose it would be nice if all engineering texts were as easy to read as the popular novel of the day. Unfortunately, assuming you are a water resource engineer like me, we wade through a topic which is not easily written. I first used this book during my Masters Degree program. The instructor was not as helpful as I would have liked, but since all of the lectures, homework and tests were pulled from the book, I decided to stop listening and start reading. With a bit of patience, trying to acclimate to the authors' presentation style, I found the book to be helpful. The description and calculation of Unit-hydrographs, hydrographs and moving between the two was very helpful. Either during, or shortly after taking this course I took the Professional Engineers licensing exam and, to my success, used this book on a couple of questions related to the unit-hydrograph method. Overall the book deserves 4 stars for being a good place to start. It lacks the final fifth star because it does get a little confusing as the authors attempt to explain many more competing approaches than they should have. There were also a couple of errors in the calculations used as examples, which had me scratching my head for a while. The good thing is that the description of the methods shown in the examples was correct, so whoever created the examples did not follow the direction properly a couple of times. I recommend this book for anyone trying to study for the P.E. exam, or as a desk reference at work when you want to know what your hydrology software is doing.
