Gravel Bed Rivers

Gravel-Bed Rivers: Processes, Tools, Environments presents a
definitive review of current knowledge of gravel-bed rivers,
derived from the 7th International Gravel-bed Rivers
Workshop, the 5-yearly meeting of the world's leading
authorities in the field.

Each chapter in the book has been specifically commissioned to
represent areas in which recent progress has been made in the
field. The topics covered also represent a coherent progression
through the principal areas of the subject (hydraulics; sediment
transport; river morphology; tools and methods; applications of
science).

• Definitive review of the current knowledge of gravel-bed
  rivers

• Coverage of both fundamental and applied topics

• Edited by leading academics with contributions from key
  researchers

• Thoroughly edited for quality and consistency to provide
  coherent and logical progression through the principal areas of the
  subject.

Autorentext
