Sommario/riassunto |
|
Dunes is the first book in over a decade to incorporate the latest research in this active and fast-developing field. It discusses the shapes, sizes, patterns, distribution, history and care of wind-blown dunes, and covers all aspects of dunes, terrestrial and in the Solar System.The only book to cover all dunes, terrestrial and in the Solar System, in deserts, on coasts, and in the pastRepresents the most current update on the research of dunes for over a decadeIncorporates the latest research to come out of China where the field is most rapidly expanding< |
