Arid Zone Geomorphology

The new edition of Arid Zone Geomorphology aims to encapsulate the
advances that have been made in recent years in the investigation
and explanation of landforms and geomorphological processes in
drylands. Building on the success of the previous two editions, the
Third Edition has been completely revised and updated to reflect
the latest developments in the field. Whilst this latest edition
will remain a comprehensive reference to the subject, the book has
been restructured to include regional case studies throughout to
enhance student understanding and is clearly defined into five
distinct sections; Firstly, the book introduces the reader to Large
Scale Controls and Variability in Drylands and then moves on to
consider Surface Processes and Characteristics; The Work of Water,
The Work of the Wind. The book concludes with a section on Living
with Dryland Geomorphology that includes a chapter on
geomorphological hazards and the human impact on these
environments.

Once again, recognised world experts in the field have been
invited to contribute chapters in order to present a comprehensive
and up-to-date overview of current knowledge about the processes
shaping the landscape of deserts and arid regions. In order to
broaden the appeal of the Third Edition, the book has been reduced
in extent by 100 pages and the Regional chapters have been omitted
in favour of the inclusion of key regional case studies throughout
the book. The Editor is also considering the inclusion of a
supplementary website that could include further images, problems
and case studies.

Once again, recognized world experts in the field contributed chapters in order to present a comprehensive and up-to-date overview of current knowledge about the processes shaping the landscape of deserts and arid regions.

• Includes global contribution from leading experts in the field providing the reader with a selective but balanced overview of this developing subject.
• Divided clearly into five distinct sections to ensure clear, comprehensive coverage of the subject.
• Includes key regional case studies throughout to enhance student understanding.
• Key references now included at the end of the book for ease of use.
• New chapters on Climate Framework; Desert System Variability; Pavements and Mantles; Desert Dune Processes and Histories; Geomorphological Hazards in Drylands and Arid Zone Geomorphology and 21st Century Global Warming.
