This book focuses on structural characterisation techniques for porous materials. Covering a range of techniques, including gas sorption, mercury porosimetry, thermoporometry, NMR and imaging methods, this practical guide presents the basic theory behind each characterisation technique, and discusses the practicalities of the experimental and data analysis approaches needed for complex industrial samples. The book shows readers how to approach characterising a particular sort of material for the first time and then how to develop a strategy for more in-depth analysis. It also demonstrates how to determine the best techniques for solving particular problems, and describes methods of obtaining the required information, as well as the limitations of various methods. It particularly highlights a scientific approach involving parameter validation and simple acquisition. Featuring examples taken from case studies of real-world industrial materials, this book is intended for industrial practitioners and researchers. It provides a manual of potential techniques and answers questions concerning porous materials that arise in areas such as the catalyst industry, the oil and gas sector, batteries, fuel cells, tissue engineering scaffolds and drug delivery devices.

It is evident, that for a number of ecological and technical problems in rivers and lakes a better knowledge of sediment transport and sedimentation is needed together with the ability to predict and simulate sediment behaviour. On the other hand, a stagnation of research in these topics could be observed in the last decades. At the Symposium an attempt was made to present new results in mathematics and natural sciences relevant for the sediment problem. New strategies were discussed to tackle the complexity of the problem. Basic theoretical research and laboratory experiments alone are incomplete without a feedback from field observations and measurements. For that reason well-known researchers from both basic and engineering sciences were invited.
Turbulence, non-local phenomena, stability, interaction, feedback systems, self-organization, two-phase flow and chaotic processes, numerical simulations as well as measurement techniques and field results were the keywords of the Symposium. This proceedings are a good source for those interested in the state of the art.

Field work, supplemented by laboratory studies, is a cornerstone for the geological sciences. This volume provides an introduction to general field work through selected topics that illustrate specific techniques and methodologies. One hundred and twenty-three main entries prepared by leading authorities from around the world deal with aspects of exploration surveys, geotechnical engineering, environmental management. field techniques, mapping, prospecting, and mining.
Special efforts were made to include topics that consider aspects of environmental geology in particular those subjects that involve field inspections related to, for example, the placement of artificial fills, sediment control in canals and waterways, the geologic effects of cities, or the importance of expansive soils to environmental management and engineering. In addition, some widely ranging topics dealing with legal affairs, geological methodology, the scope and organization of geology, report writing, and other concepts, such as those related to plate tectonics and continental drift, provide a necessary perspective to the arena of field geology.

The Earth's rocky mantle convects to lose heat, which comes from the liquid iron core below. The mantle's interfaces - the core-mantle boundary, and the lithosphere - may hold the key to understanding mantle motion because of the seismic anisotropy present in these parts of the Earth.
In this thesis, Andy Nowacki presents a precise but comprehensive review of the current state of the art in studying flow with anisotropy, mineral physics and geodynamics. New measurements of shear wave anisotropy in the lowermost mantle and at mid-ocean ridges are used to constrain mechanisms of creep and melt extraction in the mantle. A model of global flow is used to predict anisotropy in the deep Earth, and novel methods to forward model shear wave splitting are described. Future studies of mantle flow must incorporate the understanding gained in this thesis.
The thesis contains a substantive introduction to the structure of the Earth, seismic anisotropy in general and in the core-mantle boundary region, and mid-ocean ridge processes. It also describes novel methods for forward modelling and interpreting shear wave splitting data. Three chapters present timely research into dynamics at divergent plate boundaries and at the core-mantle boundary.

Modeling of flow and transport in groundwater has become an important focus of scientific research in recent years. Most contributions to this subject deal with flow situations, where density and viscosity changes in the fluid are neglected. This restriction may not always be justified. The models presented in the book demonstrate immpressingly that the flow pattern may be completely different when density changes are taken into account. The main applications of the models are: thermal and saline convection, geothermal flow, saltwater intrusion, flow through salt formations etc. This book not only presents basic theory, but the reader can also test his knowledge by applying the included software and can set up own models.

This book contains selected contributions from the Sixth Meeting of the International Geographical Union's Commission on Land Degradation and Desertification, held in Perth, Australia, in September 1999. Collectively, these contributions explicitly seek to understand not only the mechanisms responsible for the problem of land degradation but their social and economic implications, the means of overcoming the problems, and the policy instruments whereby remedial measures may be implemented. This breadth of approach is both distinctive and essential if the problems are to be tackled effectively. The authorship comprises of specialists (mostly geographers) from universities, research organizations, and government agencies, who provide a truly international perspective with contributions from Iceland to Australia and from the USA to Japan. Audience: The book presents current research findings which will be of particular benefit to professionals and practitioners, as well as researchers and tertiary-level educationalists who are involved with land degradation.

Geomorphology deals with some of the most striking patterns of nature. From mountain ranges and mid-ocean ridges to river networks and sand dunes, there is a whole family of forms, structures, and shapes that demand rationalization as well as mathematical description. In the various chapters of this volume, many of these patterns are explored and discussed, and attempts are made to both unravel the reasons for their very existence and to describe their dynamics in quantitative terms. Particular focus is placed on lava and mud flows, ice and snow dynamics, river and coastal morphodynamics and landscape formation. Combining a pedagogical approach with up-to-date reviews of forefront research, this volume will serve both postgraduate students and lecturers in search of advanced textbook material, and experienced researchers wishing to get acquainted with the various physical and mathematical approaches in a range of closely related research fields.

With a length of about 1200 km, the Son-Narmada-Tapti Lineament (NSL) is one of the most prominent geomorphic features in the Indian subcontinent. Anomalous conductive bodies are delineated at mid-lower crustal depths below major earthquake epicentral zones. The region has been interpreted as the collision zone of the Indian Plate with the Eurasian Plate. The NSL zone is therefore also known to be the second most important tectonic feature in the Indian geology, after the Himalayas.
The present thesis describes significant new insight into the seismotectonics of this Central India tectonic zone, based on thorough magnetotelluric studies. The main objectives of the present study are: (i) to delineate subtrappean sediments across the NSL region along four different traverses, (ii) to understand the characterization of geo-electrical structure of the crust and examine the nature of geo-electrical signatures of the known faults, (iii) to integrate the results with other geophysical data such as seismicity, gravity and heat flow, in order to understand the tectonic scenario of the region.
Deep electromagnetic (magnetotelluric) analyses were integrated in this study with gravity, seismic and heat flow studies and distinct, delineated deep crustal features. The resulting high conductivity is justified with the presence of fluids at mid-lower crustal depths. The migration of these fluids from mantle to mid-lower crustal depths through pre-existing brittle fracture/fault zones were obviously caused by the plume related to the Deccan volcanism. Migration of the fluids generated a higher fluid pressure along the faults and resulted in earthquakes.
Based on the geo-electric sections derived along the four traverses of the Narmada-Son Lineament Zone, the present study gives important clues on the subduction/collision history in this important tectonic zone.

In many geological epochs, glacial sediments are widespread. This type of sedimentation results from the interaction between atmosphere, cryosphere, hydrosphere and biosphere under temperatures ranging from 0 to -80. Two types of glacial sediments exists: those from sea-ice and those from icebergs. Both types can be subdivided into various subfacies. Most widespread in the Northern Hemisphere is the Siberian subfacies, characterized by silt and clay and often misinterpreted as sediments of temperate zones. This reference book for researchers working on this kind of sediments provides a complete overview of the various glacial deposits in the ocean.

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.

This book will open up a large body of data previously inaccessible or unknown to non-francophone geomorphologists, geologists and geographers. It provides an insight into the regional geomorphology of basement terrains in France and elsewhere which do not belong to the list of benchmark case studies, recurringly explained in mainstream textbooks. The essay style of the nine chapters, the permanent and holistic reference to landscapes of the real world, and the constant shuttle between field and laboratory studies help to remind students that the analysis of the geomorphic landscape is a humbling process of interpretation, requiring the collation of many strands of evidence. This is not always apparent in more linear textbooks on process geomorphology, where topics are dealt with in more detail but also more theoretically.

This volume is mainly concerned with landform and sediment associations in cold regions, and their transformations over time and space in response to changing environments. Most of the chapters adopt a landscape approach, with the goal of describing, interpreting and comparing regional landscapes. The emphasis here is on landscapes that are formed or constrained by cold conditions. In particular, we look at landform morphology, earth surface processes and sediments reflecting the presence of frost, ice and melt water, and the influence upon landscape of cold-adapted plants and animals. The notion of 'transition' is employed to address the ways in which environmental changes are uniquely expressed through adjustments in landforms and earth surface processes. It is shown that geomorphic transitions have, or tend to, generate their own temporal and spatial shape. They involve mechanisms or patterns of adjustment distinct from, and not readily obvious in, the mere chronology of, say, climate change or tectonics. Examples are discussed from high mountain and glacierized environments, from cold lowlands and coasts. Appropriate theoretical concerns are addressed in relation to the slope stability and extreme mass movement events, paraglacial regimes, changing distributions of permafrost, delta and other cold coastal development.

Ocean Hotspots provides a comprehensive overview of recent and ongoing research on intraplate volcanism in the ocean basins with special emphasis on the Pacific Ocean. The geology of the seamounts and their associated seamount chains is described, along with detailed geophysical, geochemical and hydrothermal observations made by a multi-disciplinary group of marine geoscientists. These observations lead to a deeper understanding of how the ascending mantle melts, represented by hotspots, are able to penetrate the lithosphere, build seamounts, and enhance hydrothermal circulation. The "fixed" hotspot-generated seamount chains also provide key constraints on plate tectonic reconstructions on the Earth's crust.

Antarctica, the sixth continent, was discovered more than 160 years ago. Since then this large, mysterious continent of ice and penguins has attracted world interest. Scientific expeditions from various countries have begun to study the geographical and natural conditions of the icy continent. Systematic and comprehensive inves tigations in the Antarctic started in the middle of our century. In 1956 the First Soviet Antarctic Expedition headed to the coast of Antarctica. Their program included studies of the atmosphere, hydrosphere and cryosphere. Thirty years have since passed. Scientists have unveiled many secrets of Antarctica: significant geophysical processes have been investigated, and a large body of new information on the Antarctic weather, Southern Ocean hydrology and Antarctic glaciers has been obtained. We can now claim that the horizons of polar geo physics, oceanology, and particularly glaciology, have expanded. Scientific inves tigators have obtained new information about all Antarctic regions and thus have created the opportunity to use the Antarctic in the interests of mankind."

Deserts are parts of the Earth that receive little or no rain; 25 cm or less per year. The physical processes that act upon these parched lands are vastly different from those that shape the more humid parts of the terrestrial landmasses. In the desert, wind is a major agent of erosion and transportation. As the results of recent space missions have indicated, this is also true in the case of the planet Mars. Thus, our understanding of desert processes sheds light on fundamental planetary processes that may apply on any planetary body that is enveloped by a windy atmosphere. An understanding of the physical layout of arid lands, and the nature of processes that initiate changes therein is also fundamental to thoughtful utilization of these lands for the benefit of mankind. It is with this in mind that we prepared this book for publication. We believe that the collection of articles in this book will be useful to scientists who are interested in desert landforms and processes, and to planners of economic develop ment of arid lands. The book also serves as a guide for students as to the state of our knowledge in this field as well as to the topics that require additional research."

This is a detailed description of the steps leading from raw signals measured in space, to calibrated comparable long term data sets, to its final form: useful information for user communities. Examples of applications and data validations result from different investigations in the Mediteranean area. An appendix summarizes useful formulas of the evaluation of satellite data.

Coastal Lowlands by virtue of their position across the boundary of land and sea belong to the earth's most dynamic systems. This is true in the physical, i. e. geological and biological, as much as in the cultural and social sense. Although the nearness to the sea was and still is fraught with danger coastal lowlands have always attracted human interest, providing challenging opportunity, holding the promise of profitable enterprise. Coastal lowlands, especially where rivers enter the region, are the cradles of great civilisations and there, of old, populations reached highest densities. As an example, Dutch history is a tale of human struggle and endeavour with and against the sea. Dutch 'low landers' wrestled their land from the sea, in turn the sea forged a nation of independent fishermen, navigators, farmers and traders who built their towns and ships at the borders of the North and Zuyder Seas. As lowlands subside and sea level rises, apparently these days at an increasing rate, concern about this environment world-wide is also rising. It certainly was appropriate and timely for the Royal Geological and Mining Society of the Netherlands when celebrating its 75th birthday to organize and call together a symposium, focussing attention on the geology and geotechnology of coastal lowlands; geology to better understand their formation and evolution, geotechnology to better manage and harvest resources as much as protect a unique and crucial environment.

This book compares existing soil erosion models and determines their suitability for predicting the impacts of global change upon soil erosion. The common datasets used for the evaluation are drawn from both temperate and semi-arid areas; they represent 73 site-years of data from seven sites in three countries. Six field-scale erosion models are evaluated; five of these are continuous-simulation types (GLEAMS, EPIC, CSEP, MEDRUSH and WEPP), the other is event-based (EUROSERM). After an introduction, the results of the model evaluation exercise are presented. Subsequent sections deal with weaknesses or omissions in current modelling approaches, descriptions of specific erosion models, and potential or actual model applications.

This book presents in a concise format a simplified and coherent geological-dynamical history of the Indian subcontinent (including Sri Lanka, Bangladesh, Myanmar, Southern Tibet and Pakistan). Encompassing a broad array of information related to structure and tectonics, stratigraphy and palaeontology, sedimentation and palaeogeography, petrology and geochemistry, geomorphology and geophysics, it explores the geodynamic developments that took place from the beginning around 3.4 billion years ago to the last about 5,000 years before present. Presented in a distilled form, the observations and deductions of practitioners, this book is meant for teachers, researchers and students of geology, geophysics and geomorphology and practitioners of earth sciences. A comprehensive list of references to original works provides guidance for those seeking further details and who wish to examine selected problems in depth. The book is illustrated with a wealth of maps, cross sections and block diagrams - all simplified and redesigned.

This book provides a detailed overview on methods used for the dating of past torrential activity on fans and cones and fosters the discussion on the impact of past and potential future climate change on torrential processes. The book has a clear focus on the practical applications of these methods, complemented by case studies. The limits of each dating method in case of excessive natural and human interventions on fans and cones are shown.

Global warming, melting polar caps, rising sea levels and intensifying wave-current action, factors responsible for the alarming phenomena of coastal erosion on the one hand and adverse environmental impacts and the high cost of 'hard' protection schemes, on the other, have created interest in the detailed examination of the potential and range of applicability of the emerging and promising category of 'soft' shore protection methods. 'Soft' methods such as beach nourishment, submerged breakwaters, artificial reefs, gravity drain systems, floating breakwaters, plantations of hydrophylous shrubs or even dry branches, applied mostly during the past 20 years, are recognised as possessing technical, environmental and financial advantageous properties deserving more attention and further developmental experimentation than has occured hitherto. On the other hand, 'hard' shore protection methods such as seawalls, groins and detached breakwaters, artefacts borrowed from port design and construction technology, no matter how well designed and well implemented they may be, can hardly avoid intensification of the consequential erosive, often devastating, effects on the down-drift shores. Moreover, they often do not constitute environmentally and financially attractive solutions for long stretches of eroding shoreline. Engineers and scientists practising design and implementation of shore defence schemes have been aware for many years of the public demand for improved shore protection technologies. They are encouraging efforts that promise enrichment of those environmentally sound and financially attractive methods that can be safely applied.

Soil formation is related to the nature of landforms on which that formation takes place. The nature of the soil affects some of the processes shaping the landforms and which cause landscape change. An accurate assessment of the evolution of landforms and of the patterns of soil formation is possible only if the interdependence of soils and landforms is recognized. This book provides an integration of geomorphology and pedology to fully assess this relationship. After an opening chapter outlining the approach adopted, specific chapters examine the relationships between soil formation and specific suites of landform assemblages. The highly influential catena concept is followed by an analysis of soil within drainage basins, on erosion surfaces, flood plains, river terraces, coastal plains, glacial and fluvioglacial landforms, deserts and periglacial landforms. The concluding chapter addresses the way in which soils can be used to assess major phases in landscape evolution. Undergraduate students and lecturers in geography or soil sciences will find this a valuable interdisciplinary introduction to soil geomorphology.

A wide variety of problems are associated with the flow of shallow water, such as atmospheric flows, tides, storm surges, river and coastal flows, lake flows, tsunamis. Numerical simulation is an effective tool in solving them and a great variety of numerical methods are available. The first part of the book summarizes the basic physics of shallow-water flow needed to use numerical methods under various conditions. The second part gives an overview of possible numerical methods, together with their stability and accuracy properties as well as with an assessment of their performance under various conditions. This enables the reader to select a method for particular applications. Correct treatment of boundary conditions (often neglected) is emphasized. The major part of the book is about two-dimensional shallow-water equations but a discussion of the 3-D form is included. The book is intended for researchers and users of shallow-water models in oceanographic and meteorological institutes, hydraulic engineering and consulting. It also provides a major source of information for applied and numerical mathematicians.

This book is an engineering guide for design of slopes and stabilisation works in rocks and residual soils. It is tailored to the practising geotechnical engineer and engineering geologist. Engineering and engineering geology students will find it quite useful and a practical course guide. It can be used as textbook in courses on landslides and slope stabilisation. The book's purpose is to present a concise documentation on how to design slopes and how to select a slope stabilisation method. The authors were selected among those who have lots of experience in their field.
