Shows the range of subdisciplines and approaches that contribute to palaeohydrology. Includes reviews and examples of specific approaches, including gully development, drainage network development, vegetation changes, and river channel planform changes. Concentrates on middle and high latitudes.
The book provides a review of the most relevant topics on the booming discipline of palaeohydrology and focuses on previous extreme events like exceptional floods and droughts. Reviews written by leading experts of their fields are combined with selected key studies and presentations on up-to-day methodical and conceptional topics as a perspective for further research. Consequently, the compilation provides an excellent review on the state of the art of numerous relevant topics of palaeohydrology and acts as unique introduction for early career scientists and scientists of different disciplines working on hydrological extreme events, both in basic research and applied aspects.
Palaeohydrology is the study of changes in the waters of the Earth prior to continuous monitoring. Knowledge of these changes is important for the understanding of past and present environmental changes and of the form of the present-day environment. The evolution of the hydrological cycle in response to climatic change produces a chain of environmental and human consequences -- factors that are becoming more relevant as climate change is predicted. Evidence of past environmental changes may be used to validate models with which to predict future change -- thus the study of rates, mechanisms and processes of Late Quaternary hydrological changes is of critical importance. This volume is designed for all who are interested in the hydrological impacts of climatic change and the contribution that palaeohydrology can make to the study of these changes.
The studies collected in this volume were conducted as part of the International Geological Correlation Program, organized to encourage research devoted to identifying and assessing the earth's natural resources and improving the state of our environment. Representing current research in the field, this volume looks at several aspects of water as a natural resource and how natural and engineered water systems interact with the surrounding environment. Its major focus is on the environmental evolution of hydrological systems, their formation and changes over time, and the impact of human activity on such changes. Coverage includes an analysis of climatic change in Central Britain over the past millenium; the palaeoecology of the Severn Basin during the late Quaternary Age; prehistoric irrigation practices in the Severn Basin; and an overview of the evolution of European rivers. The discussions offered here are intended to provide clues to possible approaches for preserving and improving the earth's environment and to extend models of environmental change in order to illuminate what to expect in the future.
Summarizes the palaeohydrological changes that have taken place during the last 15,000 years in various countries around the world. Written by leading experts in the field, it is divided into three main sections. The first section introduces the temperate zone and IGCP Project 158. Section two consists of 14 chapters describing the research conclusions from many different study areas with themes developed for each to aid in the understanding of temperate palaeohydrology. The final section provides perspectives of temperate palaeohydrology in various areas and then offers conclusions comparing and contrasting the events from one area to another in the temperate zone; explores global patterns; and points the way to continued research in the future.
The Times (Obituaries, 4 August 2008) reported that “John Thornes was one of the most eminent and influential physical geographers of his generation.” John’s keen interest in understanding landform processes and evolution was furthered through a variety of methods and informed across a range of disciplinary boundaries. In particular he pushed for better integration of monitoring, theoretical and simulation modelling, field and laboratory experimentation and remote sensing techniques. Although dominated by an interest in the Mediterranean region and problems of land degradation, his research activities ranged across a number of time scales and with other environmental perspectives. This collection of papers reflects this wide range of John’s interests through the recent work of scientists and professionals most strongly influenced by his rigorous training or leadership. The thematic focus of the book, which runs through all of the main contributions, is the integration of different methodologies and the application of this approach to improved understanding of natural systems and the development of appropriate strategies for environmental and resource management. Short overviews of John’s contributions to geomorphological research are also presented to provide context for the origins of this book.
Dreaming of Sheep in Navajo Country offers a fresh interpretation of the history of Navajo (Diné) pastoralism. The dramatic reduction of livestock on the Navajo Reservation in the 1930s -- when hundreds of thousands of sheep, goats, and horses were killed -- was an ambitious attempt by the federal government to eliminate overgrazing on an arid landscape and to better the lives of the people who lived there. Instead, the policy was a disaster, resulting in the loss of livelihood for Navajos -- especially women, the primary owners and tenders of the animals -- without significant improvement of the grazing lands. Livestock on the reservation increased exponentially after the late 1860s as more and more people and animals, hemmed in on all sides by Anglo and Hispanic ranchers, tried to feed themselves on an increasingly barren landscape. At the beginning of the twentieth century, grazing lands were showing signs of distress. As soil conditions worsened, weeds unpalatable for livestock pushed out nutritious native grasses, until by the 1930s federal officials believed conditions had reached a critical point. Well-intentioned New Dealers made serious errors in anticipating the human and environmental consequences of removing or killing tens of thousands of animals. Environmental historian Marsha Weisiger examines the factors that led to the poor condition of the range and explains how the Bureau of Indian Affairs, the Navajos, and climate change contributed to it. Using archival sources and oral accounts, she describes the importance of land and stock animals in Navajo culture. By positioning women at the center of the story, she demonstrates the place they hold as significant actors in Native American and environmental history. Dreaming of Sheep in Navajo Country is a compelling and important story that looks at the people and conditions that contributed to a botched policy whose legacy is still felt by the Navajos and their lands today.
Geomorphology is a major area of geography in which a great deal of new research developments have recently taken place. This book is an international, authoritative, up-to-date review of all the major areas within geomorphology, assessing recent trends and surveying recent advances to portray the latest state of the art. Many case studies and examples are examined and these are drawn from throughout the world. Geographical methodology and applications are considered and likely future developments are assessed.
After the excitement of its discovery and excavations in the early 1960s, the world-important site of Çatalhöyük has remained dormant for 30 years. This is Volume 1 of the Çatalhöyük Research Project series. It describes the first phase of renewed archaeological research at the site. It reports on the work that has taken place on the surfaces of the east and west mounds and in the surrounding regions. It also discusses the material from the 1960s excavation in museums, which has been re-examined. The result is that new perspectives can be offered on the internal organization and symbolism of a site which is central to our understanding of the earliest development of complex societies.
