Ground-penetrating radar (GPR) is a rapidly developing field that has seen tremendous progress over the past 15 years. The development of GPR spans aspects of geophysical science, technology, and a wide range of scientific and engineering applications. It is the breadth of applications that has made GPR such a valuable tool in the geophysical consulting and geotechnical engineering industries, has lead to its rapid development, and inspired new areas of research in academia. The topic of GPR has gone from not even being mentioned in geophysical texts ten years ago to being the focus of hundreds of research papers and special issues of journals dedicated to the topic. The explosion of primary literature devoted to GPR technology, theory and applications, has lead to a strong demand for an up-to-date synthesis and overview of this rapidly developing field. Because there are specifics in the utilization of GPR for different applications, a review of the current state of development of the applications along with the fundamental theory is required. This book will provide sufficient detail to allow both practitioners and newcomers to the area of GPR to use it as a handbook and primary research reference. *Review of GPR theory and applications by leaders in the field *Up-to-date information and references *Effective handbook and primary research reference for both experienced practitioners and newcomers

Large Rivers: Geomorphology and Management explores an important topic in geomorphology and sedimentology: the form and function of major rivers. Our knowledge of the big rivers of the world is limited. It is currently difficult to recognise large rivers of the past from relict sedimentary deposits or to structure management policies for long international rivers. This exciting book brings together a set of papers on large rivers of the world, as a unique introduction to a demanding subject. The book includes thirty chapters and is organised into three sections. The first part is on the environmental requirements for creating and maintaining a major river system. The second is a collection of case studies on 14 large rivers from different continents, covering a range of physical environments. The third section includes chapters on the measurement and management of large rivers. First book to offer in a single volume state-of-the-art knowledge on management and geomorphology of large rivers of the world A pioneering study, pushing the boundaries of our knowledge related to big rivers Includes comprehensive case studies covering the major large rivers of the world including Amazon, Mississippi, Nile, Congo, Indus, and Mekong Written by a leading team of distinguished, international contributors Large Rivers: Geomorphology and Management is essential reading for postgraduate students and researchers in fluvial geomorphology, hydrology, sedimentary geology, and river management. It is also of relevance to engineers and environmental consultants in the private and public sectors working on major rivers of the world.

River Processes deals primarily with flow and sediment dynamics in alluvial channels. It emphasises water flows (basic principles and characterisation), fluvial sediment, processes of erosion and sediment transport, bedforms that result from flow-bed sediment interactions in sand and gravel, flow and sedimentary processes in curved, braided and confluent channels, as well as aquatic habits. River Processes provides a comprehensive synthesis of current knowledge about physical processes in alluvial channels, with an emphasis on the recent work on flow-bed-sediment transport interactions. It is intended primarily for undergraduate students interested in fluvial studies as part of physical geography, earth sciences, environmental sciences and ecology courses. The textbook is fully illustrated throughout with line drawings and photographs.

David Knighton's best-selling book looks at the wide range of forms developed by natural rivers and the processes responsible for that development. The book combines empirical and theoretical approaches, and provides a critical assessment of the many schools of thought which have emerged for dealing with adjustment in the fluvial system. It is fully illustrated throughout by a superb range of figures, photographs and tables. Starting with the network scale, the book examines the interaction of hillslopes, drainage networks and channels, and goes on to considerations of catchment hydrology and catchment denudation. Fluvial processes are analysed in detail, from the mechanics of flow to sediment transport and deposition. Detailing the major components of river channels, the book examines the nature of river adjustment, particularly with respect to equilibrium concepts, and concludes with a look at channel changes through time, affected by flood discharges, climatic change and human activities.

This collection of papers is based largely on contributions by participants in a series of special sessions at the June 1995 South East Asia Conference of the International Association of Geomorphologists. The concept that draws these papers together is best explained in the following excerpt from the call for papers that was issued in advance of the conference: The purpose of this special session is to provide an opportunity for discussion of the diversity of fluvial forms that may arise in unusual settings These may include settings where external forcing factors exert a powerful influence precluding or modifying the type of equilibrium form that is expected to develop under quasi-stable conditions in an alluvial channel: for example, patterns of response to tectonic activity longitudinal variations in channel and floodplain form associated with spatially varying patterns of bedrock lithology or jointing arid region rivers with longitudinal discharge trends that are not mono-tonically increasing. Also of potential interest are morphological features forming under climatic/hydrologic regimes associated with monsoon, tropical wet, extremely arid or extremely cold environments; or patterns of vegetation distribution that exert a controlling influence on channel form. It is hoped that the papers contributed to this session will encompass a broad range of geographic as well as morphological diversity. The underlying premise was that the world s rivers encompass a wide range of influences and associated fluvial forms, but that the geomorphic literature traditionally has focused most intensively on a subset of those forms (mostly comprised of alluvial rivers from humid temperate, semiarid or proglacial environments), and may not treat a spectrum of morphological types that is proportionately representative of the rivers that actually exist on the earth s surface. Thus the intention of this volume is, first and foremost, to present an international set of case studies with a strong descriptive component, representing the diversity of fluvial forms. To quote Baker and Komatsu in the opening paper of this volume "excitement and pleasure in science derive not so much from achieving the final explanation as from discovering the fascinating range of new phenomena to be explained". It is our hope that readers of this volume will share some of that excitement and pleasure.

Papers in this title offer understanding of allocyclic controls on non-marine stratigraphy, allowing better predictions about the nature and geometry of strata within areas of basins where data are more limited. Thus one can better estimate the potential for oil, gas, coal, or mineral accumulations. Authors examine the relative importance of eustasy, climate, and sedimentation supply in determining the nature of lithologies and the packaging of continental strata.

"Situated on the western margin of Europe, Wales has been moulded by the erosional and depositional power of its fresh waters by virtue of high rainfall interacting with extensive regions of bedrock and post- Ice Age glacial debris. The result is a still evolving landscape rich in upland bogs, springs, mountain streams and lakes, rivers running through deeply eroded valleys, and large, lowland rivers meandering across wide floodplains into estuaries and the sea. Subsequent chapters bring together, for the first time, the combined expertise of a group of scientists whose intimate and collective knowledge of the Welsh aquatic landscape is unparalleled. The authors begin by describing the knowledge base of these important habitats, emphasising the structure and role of their plant, animal, and microbial communities. Upon this are built chapters that review the pioneering role of Welsh river studies in the development of running water science and, very poignantly, assess the high degree of human alteration of the principality's riverine ecosystems. These are followed by chapters that discuss the need for further scientific study, management, conservation, restoration and education so that future impacts on Welsh waters may be understood and minimised. Throughout the book flows the underlying theme that there has been and always will be a close link between water resources and the development of Welsh society."--Publisher's description.

Developments in the modelling of sediment transport in rivers and the interactions with the river-bed have been remarkable over the last two decades. This progress has increased the understanding of the nature of turbulence, and the ability to replicate mathematically simple flow-particle interactions which can be observed experimentally. In addition, quite elegant models of stratigraphic complexes have evolved because of the growing computational power available to scientists. As always, additional knowledge has raised even more intriguing questions and the quest for explanation of phenomena has led to increased specialisation. Therefore, there are few fluid dynamicists or sedimentologists who can successfully span the two disciplines. The intention of this book is to assist various specialists on keeping abreast of current developments in related areas. The book initially focuses on hydrodynamics of turbulent flow, followed by basic two and three-dimensional flow through straight and curved channels and the flow over bed topography. This is then followed by a consideration of initial motion, sediment transport and particle sorting. The potential for modelling fluidsediment interactions is provided at the end of the first section. Linking chapters then follow, considering the preservation potential of fluvial bedforms in the stratigraphic record and the basic variety of channel morphology recognised in sedimentary studies. Subsequent chapters consider reconstructing hydraulic process and fluvial morphology from stratigraphy; the influence of bedform and depositional controls on packing of economically important sedimentary rocks; and recent advances in modelling subsurface fluvial stratigraphy. A final chapter provides a brief view of future perspectives. The objective of this volume is to review recent advances made by geologists and hydrodynamicists in an accessible manner and to promote an increased and fruitful dialogue between sedimentary geologists, geomorphologists and hydrodynamicists.
