The plate tectonics revolution in the earth sciences has provided a valuable new framework for understanding long-term landform development. This innovative text provides a comprehensive introduction to the subject of global geomorphology, with the emphasis placed on large-scale processes and phenomena. Integrating global tectonics into the study of landforms and incorporating planetary geomorphology as a major component the author discusses the impact of climatic change and the role of catastrophic events on landform genesis and includes a comprehensive study of surface geomorphic processes.

Remote Sensing of Glaciers - Techniques for Topographic, Spatial and Thematic Mapping of Glaciers (Paperback): Petri Pellikka,... Remote Sensing of Glaciers - Techniques for Topographic, Spatial and Thematic Mapping of Glaciers (Paperback)
Petri Pellikka, W. Gareth Rees
R1,848 Discovery Miles 18 480 Ships in 12 - 17 working days

Glaciers and ice sheets have been melting significantly during recent decades, posing environmental threats at local, regional and global scales. Changes in glaciers are one of the clearest indicators of alterations in regional climate, since they are governed by changes in accumulation (from snowfall) and ablation (by melting of ice). Glacier changes have been measured for the last century by traditional field measurements, resulting in long time series for a few glaciers. Remote sensing data and methods, and geographic information systems, provide the means to allow glacier changes to be monitored at a global scale, to be analysed rapidly and to store the results and present information to both scientific and popular audiences in a way which was not possible before the digital revolution. Remote sensing of glaciers began with terrestrial and aerial photography during the middle of the 20th century, but today the discipline embraces a large variety of data types from laser scanner data to very high resolution satellite imagery, which can be applied to the mapping of glacier changes in terms of area, surface zonation or thickness. This book highlights the history of the remote sensing of glaciers, the physics of glaciers and remote sensing of them, and focuses particularly on modern data and methods used by remote sensing specialists and glaciologists. The book presents examples of glacier research carried out, for example in the Alps, Norway, Iceland, Caucasus, Patagonia, Rocky Mountains, Pakistan, Antarctica, New Zealand, and Svalbard. This book is of interest to specialists and students working in the field of remote sensing, glaciology, physical geography, geology and climate change.

F.G. Dimes, J. Ashurst
R3,908 Discovery Miles 39 080 Ships in 12 - 17 working days

One of the problems which beset the practical conservation of stone buildings is the fragmentation of the disciplines involved. This book, with both volumes now available as one invaluable paperback, brings these disciplines together by the involvement of contributors with different experiences and approaches to the same material.


Part one is an introduction to the complexities and background history of stone conservation followed by the most comprehensive description yet produced of the building and decorative stones used in the British Isles.
In part two, practitioners involved in stone conservation describe ways in which major structural masonry problems, secondary building problems and different stone surface conditions may be treated. A variety of building types and environments has been used to ensure that the broad scope of common problems is covered. This second part of the book will be of practical value to art historians, archaeologists, architects, surveyors and engineers, masonry contractors and sculpture conservators in solving problems and in learning to use each other's skills and experience.

Salt Weathering Hazards (Hardcover): A Goudie Salt Weathering Hazards (Hardcover)
A Goudie
R6,109 Discovery Miles 61 090 Ships in 12 - 17 working days

The hazards posed to engineering structures by salt weathering are increasing because of such diverse factors as the spread of irrigation and high levels of atmospheric pollution. Salt weathering is also a potent cause of rock decay and geomorphological change in polar, coastal and desert environments. The book discusses the reasons why the hazards are increasing and presents striking case studies from many parts of the world. It also discusses the nature and sources of different salts, the mechanisms that cause the deterioration of building materials and natural rock outcrops, the geomorphological processes of salt attack and their impact on landform development, and the strategies and techniques that are available to combat salt attack. The book is extensively illustrated and has a very comprehensive bibliography of the multi-disciplinary literature.

Weathering - An Introduction to the Scientific Principles (Paperback): Will J. Bland, David Rolls Weathering - An Introduction to the Scientific Principles (Paperback)
Will J. Bland, David Rolls
R1,390 Discovery Miles 13 900 Ships in 12 - 17 working days

Our landscape is constantly changing, but before the dramatic effects of erosion and mass movement take place, more subtle forces work on the rocks, minerals and soils around us. Weathering is the initial process which exposes the top few layers of the Earth to the potential for change.
This book provides an introduction to the scientific principles behind mechanical, chemical and biological weathering. Starting with a consideration of the chemical and physical properties of rocks and water, the authors proceed to an accessible explanation of the weathering processes themselves, concluding with a review of weathering rates and intensities, and a survey of the effects of weathering on the landscape. Assuming little background knowledge, the authors develop ideas from first principles to provide a straightforward introduction to weathering for students of geography, geology and earth and environmental science.

Coastal Dunes Form and Process Edited by Karl F. Nordstrom Norbert Psuty Institute of Marine and Coastal Sciences, Rutgers University, New Brunswick, New Jersey 08903, USA and Bill Carter Department of Environmental Studies, University of Ulster, Coleraine, Co. Londonderry, BT52 1SA, Northern Ireland Coastal Morphology and Research Series Series Editor: Eric C. F. Bird This book deals with the formation and establishment of coastal dunes--considering both forms and processes in a wide variety of environments. These landforms are among the most sensitive to environmental change, yet they provide extensive protection against both short-term erosion and flooding and long-term sea-level rise. Until now, there has not been any major book to deal specifically with coastal dunes. The current volume surveys a range of dune features, such as the ephemeral characteristics in the rapidly subsiding Mississippi delta, the extensive sand sheets of Australia and South Africa and the Holocene dunes of Western Europe and North America. This book will provide essential background information for ecological and management studies of coastal dunes. It will be of immense value to geomorphologists, ecologists and other environmental scientists who work on the management of coastal dunes.

Wieslaw Ziaja
R1,603 Discovery Miles 16 030 Ships in 9 - 15 working days

This revised edition describes the transformation of the environment and landscape of Western Sorkapp Land based on research data collected by Jagiellonian University scientific expeditions in the period 1980-1986 and in 2008. It also outlines potential directions of the transformation of Western Sorkapp Land.Western Sorkapp Land has been experiencing dramatic natural changes such as glacial recession, coastline retreat, emergence of new landforms and Quaternary deposits, as well as changes in the water drainage and network due to global warming. Western Sorkapp Land is a very remote and diverse region, which is representative of the European Arctic. The establishment of South Spitsbergen National Park has led to a regeneration of the local reindeer herd, which has caused overgrazing of the local tundra resulting in altered plant communities and soil erosion. They have also destroyed numerous bird nests. The transformation of Western Sorkapp Land is set to continue.

Mark S. Reed, Lindsay C. Stringer
R3,911 Discovery Miles 39 110 Ships in 12 - 17 working days

Although much is known about the processes and effects of land degradation and climate change, little is understood about the links between them. Less still is known about how these processes are likely to interact in different social-ecological systems around the world, or how societies might be able to adapt to this twin challenge. This book identifies key vulnerabilities to the combined effects of climate change and land degradation around the world. It identifies triple-win adaptations that can tackle both climate change and land degradation, whilst supporting biodiversity and ecosystem services. The book discusses methods for monitoring effects of climate change and land degradation, and adaptations to these processes. It argues for better co-operation and knowledge exchange, so that the research, land user and policy communities can work together more effectively to tackle these challenges, harnessing the "wisdom of crowds" to assess vulnerability and adapt to climate change and land degradation, whilst protecting livelihoods and biodiversity.

Noel Duncan
R2,627 Discovery Miles 26 270 Ships in 12 - 17 working days

The main mesological factors that determine vegetation activity are moisture and temperature (Ferreras Chasco, 2000). Under certain conditions of moisture and temperature a limitation in growth can appear and, if these conditions do not improve, plants can enter into a state called vegetative paralysis. This book discusses the land surface of the basin of the Guadaira River, and it pays attention to the study of riparian vegetation on different channels that belong to its countryside stretch. It also presents research on the modern spatiotemporal variability of the morphology of High Arctic proglacial rivers; and provides a review on the general properties of ancient Martian systems, focusing on possible issues related to the lack of biogenic effects on Mars, and analysing mainly riverbank related erosional and depositional structures.

Natural disasters are occasional intense events that disturb Earth's surface, but their impact can be felt long after. Hazard events such as earthquakes, volcanos, drought, and storms can trigger a catastrophic reshaping of the landscape through the erosion, transport, and deposition of different kinds of materials. Geomorphology and Natural Hazards: Understanding Landscape Change for Disaster Mitigation is a graduate level textbook that explores the natural hazards resulting from landscape change and shows how an Earth science perspective can inform hazard mitigation and disaster impact reduction. Volume highlights include: Definitions of hazards, risks, and disasters Impact of different natural hazards on Earth surface processes Geomorphologic insights for hazard assessment and risk mitigation Models for predicting natural hazards How human activities have altered 'natural' hazards Complementarity of geomorphology and engineering to manage threats

Zoogeomorphology - Animals as Geomorphic Agents (Paperback): David R. Butler Zoogeomorphology - Animals as Geomorphic Agents (Paperback)
David R. Butler
R1,078 Discovery Miles 10 780 Ships in 12 - 17 working days

Animals as geomorphic agents have primarily been considered "curiosities" in the literature of geomorphology, whose spatial and quantitative influences have been seen as both limited and minor. Zoogeomorphology: Animals as Geomorphic Agents examines the distinct geomorphic influences of invertebrates, ectothermic vertebrates, birds, and mammals, and demonstrates the importance of animals as landscape sculptors. Specific processes associated with the diversity of animal influences in geomorphology are examined, including burrowing and denning, nesting, lithophagy and geophagy, wallowing and trampling, food caching, excavating for food, and dam building by beavers. Particular emphasis is placed on terrestrial animals, although aquatic animals are also discussed where appropriate. This book, which is the only one available wholly devoted to this topic, will interest graduate students and professional research workers in geomorphology, ecology, environmental science, physical geography, and geology.

Our Dynamic Earth: A Primer (Paperback, 1st ed. 2022): Matthew R. Bennett Our Dynamic Earth: A Primer (Paperback, 1st ed. 2022)
Matthew R. Bennett
R1,445 Discovery Miles 14 450 Ships in 10 - 15 working days

Students taking undergraduate degrees in geography, ecology, earth science, and environmental science frequently take an introductory unit in Physical Geography. Some will have not done any geography since their early teens, while others have more recent knowledge. This range of backgrounds can be challenging for both the instructor and the student, this primer aims to help. A primer is a readable introduction to a subject, more technical than a piece of popular science, but less detailed than a specialist textbook. It aims to give the reader a platform in a subject with which they may be unfamiliar, so that they can proceed simultaneously, or sequentially, to more advanced texts and information. Ideally the primer should have something for those without any knowledge, while also challenge and entertaining those who do. Not quite bedtime reading, but a step in that direction. Our Dynamic Earth introduces students to the Earth's origins, to plate tectonics, atmospheric and oceanographic circulation, as well as to a range of Earth surface processes. Idea to get you started in your studies.

Pravat Kumar Shit, Biswajit Bera, Aznarul Islam, Sandipan Ghosh, Gouri Sankar Bhunia
R4,567 Discovery Miles 45 670 Ships in 10 - 15 working days

This volume provides a versatile introduction to the study of drainage basin evolution, morphology, drainage basin hydrology and sedimentology, human interference, natural and anthropogenic hazards and various management techniques. This book offers the responsible factors of sediment yield and their absolute and specific growth and rate of delivery through tributaries to the main streams. Rivers are important geomorphic agents which reflect an amazing variety of form and behaviour, showing the wide range of natural environment in which they are originated. The drainage system evolution and spatial network development within the dynamic nature are being discussed and how they are adjusted in the geomorphic time scale over the millions of years. This book shows how drainage systems function and react to change and why this thoughtful is required for flourishing integrated basin management. In tropical and sub-tropical countries population pressures as well as different developmental projects are being executed on the drainage basin without proper planning. Today scientists consider drainage basin as an administrative unit during implementation of regional projects. In this context this book will carry a bench mark for scholars and young scientists.

Zhijun Dai
R4,973 Discovery Miles 49 730 Ships in 10 - 15 working days

This book provides a comprehensive and systematic analysis of the morphodynamic process of the Changjiang River from upstream to estuary in the Anthropocene. As the longest river in China, the Changjiang River has nurtured Chinese civilization with ample natural resources for thousands of years. Evidence highlights that the Changjiang River has experienced intensive human interference and indicated dramatic changes in the Anthropocene, including "no flood in flood season, no dry in dry season" in discharge; "less flood in flood season, more dry in dry season" in sediment; riverbed shifts from accretion to erosion; lakes in the middle-lower reach turn from sediment sink to source; estuarine tidal flat exhibits self-organization characteristics and maintains the current accretion state; estuarine branches that connect to the sea show district morphodynamic patterns; and depocenters of the submerged delta indicate periodic shifts. The book stresses that dam construction upstream, practically the Three Gorges Dam, the world's largest hydraulic engineering project, has significant influences on the hydrology and geomorphology of the middle-lower reach but has a slight effect on estuarine delta development. The geomorphological structure of the estuarine channel is dominated by local land reclamation, navigation, and dredging. This book clarifies the river-estuary morphodynamics of the Changjiang River and indicates the general features of global mega rivers under human interference as well as their own response mechanisms. This book also exhibits the potential risk of river-estuary deltas in the future, as both material and dynamics are experiencing acceleration adjustment.

Glacially-Triggered Faulting (Hardcover): Holger Steffen, Odleiv Olesen, Raimo Sutinen Glacially-Triggered Faulting (Hardcover)
Holger Steffen, Odleiv Olesen, Raimo Sutinen
R2,690 Discovery Miles 26 900 Ships in 12 - 17 working days

Glacially triggered faulting describes movement of pre-existing faults caused by a combination of tectonic and glacially induced isostatic stresses. The most impressive fault-scarps are found in northern Europe, assumed to be reactivated at the end of the deglaciation. This view has been challenged as new faults have been discovered globally with advanced techniques such as LiDAR, and fault activity dating has shown several phases of reactivation thousands of years after deglaciation ended. This book summarizes the current state-of-the-art research in glacially triggered faulting, discussing the theoretical aspects that explain the presence of glacially induced structures and reviews the geological, geophysical, geodetic and geomorphological investigation methods. Written by a team of international experts, it provides the first global overview of confirmed and proposed glacially induced faults, and provides an outline for modelling these stresses and features. It is a go-to reference for geoscientists and engineers interested in ice sheet-solid Earth interaction.

Javier Doniz-Paez, Nemesio M. Perez
R1,328 Discovery Miles 13 280 Ships in 10 - 15 working days

This open access book explores El Hierro Island, which is geologically the youngest of the Canary Islands (Spain). Having registered its latest volcanic eruption in 2011-2012, it is an oceanic subtropical island with low population pressure and a largely unchanged natural landscape. Accordingly, a great geodiversity of volcanic morphologies and erosion processes has been preserved. In addition, half of the land is protected as a Biosphere Reserve and as a UNESCO Global Geopark, and the island is pursuing energy self-sufficiency. Local tourism is a sustainable activity, as the main attractions are either diving or hiking through the island's various volcanic landscapes. Covering these and other aspects, and using accessible language, the book will appeal to scientists specialized in geotourism, active leisure entrepreneurs, and members of the general public interested in volcanic geoheritage and geotourism.
