From the reviews: "The book aims to give a unified mathematical theory of branched transportation (or irrigation) networks. ... The logical structure of the book makes it easy to learn the theory. ... this book, in addition to being a great source of references is also extremely suitable for a study from scratch. The theory is presented while avoiding useless complications and keeping the language simple. I would also suggest this book to graduate students who want to enter this very interesting research field." (Luigi De Pascale, Mathematical Reviews, Issue 2010 e)
