Contenu

A primer, written in a very clear and instructive style, reveals the extraordinary complexity of the phenomena involved in "making" a river. The authors introduce us to river hydromorphology, a scientific discipline that has come of age, and explain the geomorphological characteristics of rivers, from the riverbed itself to the floodplain, that create the major types of habitat on which aquatic and terrestrial species depend. In the process, it becomes clear that the good ecological operation of rivers and their corridors depends on maintaining and restoring the natural geodynamic processes and the resulting geomorphological characteristics.

Approximately 400 photos and diagrams are another of the book's strong points, helping to explain what the human eye alone cannot grasp and to appreciate the various scales on which river phenomena take place, from individual pebbles to entire basins and even entire countries.
