Geomorphology of Desert Dunes

Synopsis

Sand dunes cover up to a quarter of many desert regions. Understanding the factors that determine their shape, size and dynamics is important to an understanding of many aspects of the geomorphology and ecology of desert regions, as well as to resource management in these areas. This book offers a comprehensive understanding of how desert dunes are formed, how they change and their environmental importance. Analyzing dune types, patterns, sand seas and sediments, and dune dynamics and processes at different temporal and spatial scales, the author draws on extensive research from the deserts of South Africa, North America, India, Northern Europe and Australia. Investigating the role of climatic change,The Geomorphology of Desert Dunesconcludes that a better understanding of dune processes and dynamics is vital for effective and appropriate mitigation of environmental problems in arid regions.

Excerpt

This book is a personal view of the geomorphology of desert dunes that has developed from my research on dune sediments, processes, and dynamics over the past two decades. This work has been made possible by research support from a variety of organizations, including the Royal Geographical Society, the Royal Society, and the National Geographic Society; the Universities of Cambridge, Witwatersrand, and Cape Town; the Transvaal Museum; the Foundation for Research Development (South Africa); NASA, NATO, and the National Science Foundation.

In the course of my work, I have interacted with many individuals who have provided assistance and discussion of problems and results. I thank them all for their company and time. I would like to single out A.T. (Dick) Grove (University of Cambridge), Mary Seely (Desert Ecological Research Unit of Namibia), Ron Greeley (Arizona State University), Gary Kocurek (University of Texas at Austin), and Bill Nickling (University of Guelph) as individuals who have made major personal contributions to my thinking on aeolian processes and dunes.

Many individuals have helped me in producing this book. In particular, Dale Ritter of the Quaternary Sciences Center, Desert Research Institute, provided institutional support; Rob Bamford did all the drafting for the figures; and Liane Alessi assisted with proof reading.
