Rough-Hewn Land

A Geologic Journey from California to the Rocky Mountains

"Unfold a map of North America," Keith Heyer Meldahl writes, "and the first thing to grab your eye is the bold shift between the Great Plains and the Rocky Mountains." In this absorbing book, Meldahl takes readers on a 1000-mile-long field trip back through more than 100 million years of deep time to explore America’s most spectacular and scientifically intriguing landscapes. He places us on the outcrops, rock hammer in hand, to examine the evidence for how these rough-hewn lands came to be. We see California and its gold assembled from pieces of old ocean floor and the relentless movements of the Earth’s tectonic plates. We witness the birth of the Rockies. And we investigate the violent earthquakes that continue to shape the region today. Into the West’s geologic story, Meldahl also weaves its human history. As we follow the adventures of John C. Frémont, Mark Twain, the Donner party, and other historic characters, we learn how geologic forces have shaped human experience in the past and how they direct the fate of the West today.

Late Cenozoic Drainage History of the Southwestern Great Basin and Lower Colorado River Region

Geologic and Biotic Perspectives

Papers in this title were selected from presentations from an April 2005 workshop sponsored by the U.S. Geological Survey Earth Surface Dynamics Program, the U.S. Geological Survey National Cooperative Geologic Mapping Program, and the Smithsonian Institution. Papers are divided into two broad topics of the configuration, areal extent, and temporal development of the chain of interconnected lakes that emptied into Death Valley during periods of the Pleistocene, and the late Cenozoic history of drainage integration in the lower Colorado River region. Papers are occasionally illustrated in both color and black-and-white; the publication contains no index.

Global Continental Palaeohydrology

Palaeohydrological research is a comparatively recent development. However, research undertaken has already demonstrated a significant multidisciplinary impact and shown how palaeohydrology can provide an important contribution to the study of global change. Although a considerable amount of exciting palaeohydrological research has been applied to particular areas, there has not previously been a systematic approach to research into the palaeohydrology of the Earth s surface. It was for this reason that a Commission was established by INQUA in 1991 on Global Continental Palaeohydrology. This volume provides the background to that exciting international research project and has been written to provide a basis for understanding the current state of research into the palaeohydrology of the land surface of the Earth. It therefore gives a summary of the work achieved to date and of the research investigations currently taking place, together with an indication of the way in which palaeohydrological research relates to other global research programmes.

Megaflooding on Earth and Mars

Megaflooding is the sudden discharge of exceptional volumes of water. Megafloods have significantly altered the terrain of Earth and Mars, and may have acted as triggers for climate change on these planets. Recently, research into megaflooding has made important advances: on Earth, real-time measurements of contemporary floods in Iceland complement research into older and larger terrestrial floods, while on Mars terabytes of data from several spacecraft orbiting that planet are dramatically revising our view of flooding there. Beginning with a historical overview of flood science, the book presents sections on morphology and mechanisms, flood sedimentology, and modelling, each illustrated with examples from Earth and Mars. By juxtaposing terrestrial and Martian research, this volume creates a unique synthesis to further our understanding of these enormous paleoflood events. It is an invaluable reference for researchers and students of hydrology, geomorphology, sedimentology and planetary science, as well as environmental and hydraulic engineers.

Incised River Channels

Processes, Forms, Engineering, and Management

Incised river channels are ubiquitous features of landscapes disturbed by environmental change. Problems associated with channel incision include undermining of structures, downstream sedimentation, severe bank erosion and widening, and degradation of aquatic and riparian habitats. In Incised River Channels, research from the disciplines of geomorphology, hydraulics, sediment transport, ecology, environmental management and river engineering is brought together to develop a detailed, integrated treatment, over a range of spatial and temporal scales, of the dynamic behaviour of unstable incised rivers. The book emphasizes the need for improved understanding of the processes and mechanisms of channel adjustment and evolution to underpin sustainable river management and engineering. It contains important original contributions from an international authorship. Contributors include university and government scientists and researchers, as well as practitioners from regulatory and consultancy organizations. Divided into three thematic sections, Incised River Channels covers the nature and significance of incised channels, processes, and mitigation and management. Fundamental principles are illustrated using case studies from a wide range of physiographic environments, providing a wide geographical coverage. This volume will be of interest to academics and advanced level students who are studying fluvial geomorphology and/or river engineering. It will also be of appeal to all those interested in river adjustment and management.

Palaeohydrology and Environmental Change presents the most recent advances in the study of global changes in the hydrological regime during the last 20000 years. The book brings together new contributions; on regional palaeohydrology with case studies from all over the world; and on new methodologies and techniques used on palaeohydrological reconstructions. There are several key points that make this book an essential review to the international scientific community: The major emphasis is on areas very sensitive to climate changes such as the Mediterranean, Tundra regions and the Tropical Zones of Asia, Africa and America. New interdisciplinary methodologies in reconstructing palaeohydrological changes including palaeoecology, pollen and lichen analysis, identification of anthropogenic stressors and changes in climate circulation regimes. Modelling studies; conceptual and mesoscale models for reconstructing palaeoenvironments during the Quaternary. This book will be a valuable reference work for all professionals and students interested in quaternary environmental, climatic and hydrological history including those in the fields of geology, geography, hydrology, biogeography, archaeology, and environmental sciences.
