Book Description
Covering a large swath of the American West, the Great Basin, centered in Nevada and including parts of California, Utah, and Oregon, is named for the unusual fact that none of its rivers or streams flow into the sea. This fascinating illustrated journey through deep time is the definitive environmental and human history of this beautiful and little traveled region, home to Death Valley, the Great Salt Lake, Lake Tahoe, and the Bonneville Salt Flats. Donald K. Grayson synthesizes what we now know about the past 25,000 years in the Great Basin—its climate, lakes, glaciers, plants, animals, and peoples—based on information gleaned from the region’s exquisite natural archives in such repositories as lake cores, packrat middens, tree rings, and archaeological sites. A perfect guide for students, scholars, travelers, and general readers alike, the book weaves together history, archaeology, botany, geology, biogeography, and other disciplines into one compelling panorama across a truly unique American landscape.

Book Description
The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM). Groundwater management is a formidable challenge, one that remains one of humanity’s foremost priorities. It has become a largely non-renewable resource that is overexploited in many parts of the world. In the 21st century, the issue moves from how to simply obtain the water we need to how we manage it sustainably for future generations, future economies, and future ecosystems. The focus then becomes one of understanding the drivers and current state of the groundwater resource, and restoring equilibrium to at-risk aquifers. Many interrelated dimensions, however, come to bear when trying to manage groundwater effectively. An integrated approach to groundwater necessarily involves many factors beyond the aquifer itself, such as surface water, water use, water quality, and ecohydrology. Moreover, the science by itself can only define the fundamental bounds of what is possible; effective IGM must also engage the wider community of stakeholders to develop and support policy and other socioeconomic tools needed to realize effective IGM. In order to demonstrate IGM, this book covers theory and principles, embracing: 1) an overview of the dimensions and requirements of groundwater management from an international perspective; 2) the scale of groundwater issues internationally and its links with other sectors, principally energy and climate change; 3) groundwater governance with regard to principles, instruments and institutions available for IGM; 4) biophysical constraints and the capacity and role of hydroecological and hydrogeological science including water quality concerns; and 5) necessary tools including models, data infrastructures, decision support systems and the management of uncertainty. Examples of effective, and failed, IGM are given. Throughout, the importance of the socioeconomic context that connects all effective IGM is emphasized. Taken as a whole, this work relates the many facets of effective IGM, from the catchment to global perspective.

Book Description
"From the New York Times bestselling and award-winning author of the epic adventure tale The Emerald Mile comes the most dramatic and deeply moving account ever of walking the Grand Canyon, a highly dangerous, life-changing 750-mile trek. The Grand Canyon is an American treasure, visited by more than 6 million people a year, many of whom are rendered speechless by its vast beauty, mystery, and complexity. Now, in A Walk in the Park, author Kevin Fedarko chronicles his year-long effort to find a 750-mile path along the length of the Grand Canyon, through a vertical wilderness suspended between the caprock along the rims of the abyss and the Colorado River, which flows along its bottom. Consisting of countless cliffs and steep drops, plus immense stretches with almost no access to water, and the fact that not a single trail links its eastern doorway to its western terminus, this jewel of national parks is so challenging that when Fedarko departed fewer people had completed the journey in one single hike than had walked on the moon. The intensity of the effort required him to break his trip into several legs, each of which held staggering dangers and unexpected discoveries. Accompanying Fedarko through this sublime yet perilous terrain is the award-winning photographer Peter McBride, who captures the stunning landscape in breathtaking photos. Together, they encounter long-lost Native American ruins, the remains of Old West prospectors' camps, present day tribal activists, and signs that commercial tourism is impinging on the park's remote wildness. An epic adventure, action-packed survival tale, and a deep spiritual journey, A Walk in the Park gives us an unprecedented glimpse of the crown jewel of America's National Parks: an iconic landscape framed by ancient rock whose contours are recognized by all, but whose secrets and treasures are known to almost no one, and whose topography encompasses some of the harshest, least explored, most awe-inspiring terrain in the world"--

Book Description
There is a continued demand for well-trained and competent hydrogeologists, especially in the environmental sector. For decades, Fetter’s Applied Hydrogeology has helped prepare students to excel in careers in hydrogeology or other areas of environmental science and engineering where a strong background in hydrogeology is needed. The text’s long-standing tradition as a vital resource is further enhanced in the fifth edition by Kreamer’s added expertise. Stressing the application of mathematics to problem-solving, example problems throughout the book provide students the opportunity to gain a much deeper understanding of the material. Some important topics include the properties of aquifers, the principles of groundwater flow, water chemistry, water quality and contamination, and groundwater development and management. The addition of new case studies and end-of-chapter problems will strengthen understanding of the occurrence and movement of ground water in a variety of geological settings.

Book Description
North American deserts—lands of little water—have long been home to a surprising diversity of aquatic life, from fish to insects and mollusks. With European settlement, however, water extraction, resource exploitation, and invasive species set many of these native aquatic species on downward spirals. In this book, conservationists dedicated to these creatures document the history of their work, the techniques and philosophies that inform it, and the challenges and opportunities of the future. A precursor to this book, Battle Against Extinction, laid out the scope of the problem and related conservation activities through the late 1980s. Since then, many nascent conservation programs have matured, and researchers have developed new technologies, improved and refined methods, and greatly expanded our knowledge of the myriad influences on the ecology and dynamics of these species. Standing between Life and Extinction brings the story up to date. While the future for some species is more secure than thirty years ago, others are less fortunate. Calling attention not only to iconic species like the razorback sucker, Gila trout, and Devils Hole pupfish, but also to other fishes and obscure and fascinating invertebrates inhabiting intermittent aquatic habitats, this book explores the scientific, social, and political challenges of preserving these aquatic species and their habitats amid an increasingly charged political discourse and in desert regions characterized by a growing human population and rapidly changing climate.
