Book Description
Mechanics plays a fundamental role in aeolian processes and other environmental studies. This proposed book systematically presents the new progress in the research of aeolian processes, especially in the research on mechanism, theoretical modelling and computational simulation of aeolian processes from the viewpoint of mechanics. Nowadays, environmental and aeolian process related problems are attracting more and more attention. We hope this proposed book will provide scientists and graduate students in aeolian research and other environmental research some mechanical methods and principles and introduce aeolian related problems of environment to mathematical and mechanical scientists.

Book Description
From individual grains to desert dunes, from the bottom of the sea to the landscapes of Mars, and from billions of years in the past to the future, this is the extraordinary story of one of nature's humblest, most powerful, and most ubiquitous materials. Told by a geologist with a novelist's sense of language and narrative, Sand examines the science—sand forensics, the physics of granular materials, sedimentology, paleontology and archaeology, planetary exploration—and at the same time explores the rich human context of sand. Interwoven with tales of artists, mathematicians, explorers, and even a vampire, the story of sand is an epic of environmental construction and destruction, an adventure in staggering scales of time and distance, yet a tale that encompasses the ordinary and everyday. Sand, in fact, is all around us—it has made possible our computers, buildings and windows, toothpaste, cosmetics, and paper, and it has played dramatic roles in human history, commerce, and imagination. In this luminous, kinetic, revelatory account, we do indeed find the world in a grain of sand.

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
The old world is buried. A new one has been forged atop the shifting dunes. Here in this land of howling wind and infernal sand, four siblings find themselves scattered and lost. Their father was a sand diver, one of the elite few who could travel deep beneath the desert floor and bring up the relics and scraps that keep their people alive. But their father is gone. And the world he left behind might be next. Welcome to the world of Sand, a novel by New York Times best-selling author Hugh Howey. Sand is an exploration of lawlessness, the tale of a land ignored. Here is a people left to fend for themselves. Adjust your ker and take a last, deep breath before you enter.

Book Description
Early descriptions and considerations of the characteristics of modern eolian sand deposits, mostly in the great sand seas of the world, date back to the 1880's and 1890's, when pioneer geologists and explorers wrote their classic papers on desert dunes. One or two decades later, interest in eolian processes greatly increased when wind-formed deposits were recognized in ancient sandstones in many parts of the world and in rocks of many ages. Throughout the 20th century, as the science of geology has expanded and the programs of the U.S. Geological Survey have proliferated to keep pace, dune studies have had a similar growth. Work was initially concentrated mostly on the description of dune forms or morphology and on analysis of textural features; by midcentury, however, major contributions had been made to the physics of eolian sand by detailed studies and interpretations of minor eolian structures, by statistical analyses of cross-strata dip directions, and by the development of systems for dune classification. Most recently, interest has been renewed in detailed grain studies, in the study of cross-strata, and in interpretation of dune patterns by means of aerial photographs and Landsat imagery. A major feature of this report on global sand seas is the compilation and comparison of available data based on many different methods of investigation. The application of these studies to economic problems, which is described in one chapter, clearly illustrates the importance of eolian deposits to our present culture and to human welfare. H.
