Book Description
It is more than half a century since the publication of R. A. Bagnold’s classic book The physics of blown sand and desert dunes, and it is a tribute to the quality of Bagnold’s work that many of the fundamental principles which he developed - main valid today. His book continues to be essential reading for any serious s- dent of aeolian processes. However, the past two decades have seen an explosion in the scale of research dealing with aeolian transport processes, sediments, and landforms. Some of this work has been summarized in review papers and edited conference proceedings, but this book provides the rst attempt to review the whole eld of aeolian sand research. Inevitably, it has not been possible to cover all - pects in equal depth, and the balance of included material naturally re ects the - thors’ own interests to a signi cant degree. However, our aim has been to provide as broad a perspective as possible, and to provide an entry point to an extensive mul- disciplinary scienti c literature, some of which has not been given the attention it deserves in earlier textbooks and review papers. Many examples are drawn from existing published work, but the book also makes extensive use of our own research in the Middle East, Australia, Europe, and North America. The book has been written principally for use by advanced undergraduates, po- graduates, and more senior research workers in geomorphology and sedimentology.

Book Description
Sculpted into graceful contours by countless centuries of wind and water, the Great Sand Dunes sprawl along the eastern fringes of the vast San Luis Valley of south-central Colorado. Covering an area of nearly thirty square miles, they are the tallest aeolian, or wind-produced, dunes in North America, towering 750 feet above the valley floor. With the addition of the enormous Baca Ranch and other adjacent lands, the dunes—originally designated as a National Monument in 1932—attained official National Park status in 2004. In Sea of Sand, Michael M. Geary guides readers on a historical journey through this unique ecosystem, which includes an array of natural and cultural wonders, from the main dunefield and verdant wetlands to the summits of the Sangre de Cristo Mountains. Described by explorer Zebulon Pike as “a sea in a storm” and by frontier photographer William Henry Jackson as “a curious and very singular phase of nature’s freak,” the Great Sand Dunes are a nexus of more than 10,000 years of human history, from Paleolithic big-game hunters to nomadic Native Americans, from Spanish conquistadores and transcontinental explorers to hard-rock miners and modern-day tourists in motor homes. Like these successive waves of visitors, Sea of Sand follows the water, analyzing its critical role in the settlement and development of the region. Geary also describes the profound impact that waves of human use and settlement have had on the land—which ultimately inspired the early grassroots efforts by San Luis Valley citizens to protect the dunes from further exploitation. He examines as well the more recent legislative effort led by an unprecedented coalition of local, state, and federal agencies and organizations, including The Nature Conservancy and the National Park Service, to secure the Great Sand Dunes’ national park designation. Amply illustrated, Sea of Sand is the definitive history of the natural, cultural, and political forces that helped shape this incomparable landscape.

Book Description
It is a high valley edged by serrated peaks, a remote expanse the size of Connecticut lying, as if forgotten, between two mountain ranges. Here, North AmericaÕs tallest sand dunes blow against glacier-gouged summits, the Rio Grande begins its long journey from snowflake to saltwater, and vast reaches of desert scrub hide verdant pocket wetlands. ColoradoÕs San Luis Valley is not a place for the timid. Sizzling hot in summer, frigid cold in winter, this huge landscape is humbling in its openness, a place defined by the rhythms of natureÑand by the thrust and parry of male courting female in the ritual dance of sandhill cranes. These majestic birds arrive by the thousands twice a year to feed, rest, and socialize in the valleyÕs wetlandsÑinvisible except from the airÑand their cries temper the constant wind. Susan Tweit lives in the high desert of southern Colorado not far from the valleyÕs dunes and wetlands. With the precision of a scientist and the passion of a poet, she guides readers through this land of sand dunes and sandhill cranes, describing its natural features and tracing its human history from buffalo hunters and conquistadors to Hispanic farming communities and UFO observatories. And in stunning images, photographer Glenn Oakley brings his intimate feel for light and landscape to portraying not only the subtle beauty of this high-desert sanctuary but also the grandeur of the cranes in flight. As an intimate look at Great Sand Dunes National Park and Preserve and the San Luis Valley, this book reveals a desert place as seductive and sobering as existence itself.

Book Description
This book deals with the development of temperate coastal sand dunes and the way these have been influenced by human activity. The different states in which the habitat exists both for the beach/foredune and inland dune are reviewed against the pressures exerted upon them. Options for management are considered and the likely consequences of taking a particular course of action highlighted. These options include traditional approaches to the conservation and management of wildlife and landscapes as well as habitat restoration. The way the value of the areas changes under different management regimes is considered mainly from an environmental perspective. Consideration is given to new approaches to management and restoration including adopting a more dynamic approach. Audience This book will be of interest to academics, students and professionals concerned with policy formulation and /or actively managing coastal areas.

Book Description
This book in two volumes, and with a foreword by the renowned Professor M.A.J. Williams, draws on evidence from coastal and inland regions, including desert dunes, wind-blown dust, river and lake sediments, glacial moraines, plant and animal fossils, isotope geochemistry, soils and prehistoric archaeology to better understand the genesis and development of dunes systems in selected northern hemisphere sand dunes from Asia, Africa and the Middle East regions. The collection of research papers and case studies that are presented in this book provide the reader with a wealth of information about the distribution and types of sand dunes and an insight into the complexity of sand dune formation, migration and management. Research in many countries across the northern hemisphere shows that dunes, whether coastal or inland, are under pressure around the world. Much of the pressure comes from human activities, and the anthropogenic disturbance, when coupled with global warming and alterations to the amount, frequency and temporal distribution of precipitation could lead to more serious management challenges in the future. There is much that we still need to find out about the origin, genesis and development of sand dunes so that they can be managed better. The difficult and complex questions being repeatedly raised can be answered only by interdisciplinary endeavours. Geomorphologists, geologists, palaeontologists, climatologists, ecologists, and others, can work together on research projects that better define the origin, evolution and development of dunes, both inland and along the coasts. Many chapters in this book attempt to reconstruct past climatic changes in deserts and their margins at a variety of scales in space and time in the expectation that such information might assist in preparing us for future global warming and drying.
