The Integrated Ocean Drilling Program (IODP: 2000-2013) has provided crucial records of past and present processes and interactions within and between the biosphere, cryosphere, atmosphere, hydrosphere and geosphere. Research in IODP encompasses a wide range of fundamental and applied issues that affect society, such as global climate change, biodiversity, the origin of life, natural hazards involving the study of earthquakes processes, and the internal structure and dynamics of our planet. This compilation of major findings from the 2003-2013/14 phase of IODP, focusing on scientific results rather than description of data acquisition and early inferences, provides invaluable information. Anyone wondering what scientific drilling can achieve will gain quick understanding of the range of questions that are uniquely addressed with this methodology and the ways these data dovetail with other regional information. The excitement of breakthrough findings that occasionally accompanies a drilling project will be evident. IODP obtained unique records from the global ocean basins during the 2003-2013 program phase. This book highlights findings in three theme areas: Subseafloor life and the marine biosphere; Earth's changing environments; and Dynamics of the solid Earth. Each core or borehole log provides a window revealing insights that no other data achieve.
Geomorphological Fieldwork addresses a topic that always remains popular within the geosciences and environmental science. More specifically, the volume conveys a growing legacy of field-based learning for young geomorphologists that can be used as a student book for field-based university courses and postgraduate research requiring fieldwork or field schools. The editors have much experience of field-based learning within geomorphology and extend this to physical geography. The topics covered are relevant to basic geomorphology as well as applied approaches in environmental and cultural geomorphology. The book integrates a physical-human approach to geography, but focuses on physical geography and geomorphology from an integrated field-based geoscience perspective.
Originally published in 1995, Monitoring Active Volcanoes is a comprehensive text which addresses the importance of volcano surveillance in the context of forecasting eruptive activity and mitigating its effects. The traditional core of seismic and ground deformation monitoring is discussed, along with more innovative techniques involving the recording of microgravity and micromagnetic variations, and the changing compositions of volcanic gases and liquids. The role of satellites is stressed, particularly with regard to the capabilities for measuring surface deformation, recognizing thermal anomalies and monitoring gas and ash plumes from space platforms. This book provides an invaluable insight into how and why volcanoes are monitored. It will be of interest to volcanologists, geophysicists and earth scientists.
Originally published in 1993, Active Lavas looks at the practical aspects of monitoring uncontrolled streams of molten rock and how field data can be applied for theoretical modelling and forecasting the growth of lava flows. It describes the basic features of common subaerial lava flows and domes - both on Earth and on other bodies in the Solar System - before discussing the logistics of measuring lava properties during eruption and how these measurements are used to develop simple theoretical models for forecasting flow behaviour.

Discussions in the book present and stimulate new challenges and questions facing today's earth science and modeling communities.
Significant advances in geomatics and geomorphology are changing the way in which scientists study complex mountain environments. This book provides a critical treatment and evaluation of these recent developments. With the advent of advanced satellite sensors, high resolution satellite imagery and digital elevation, models now make possible quantitative analysis and modelling of the landscape. So it is becoming ever more important for geoscientists to integrate geomatics into their scientific investigation. This book is a "must" for any researcher actively working in geomatics, geomorphology and mountain systems. It will also be valuable to geologists and resource planners interested in the role of surface processes in complex orogens and resource assessment and sustainable development.
This book presents an overview of volcanic debris avalanche deposits, which are produced by partial volcanic edifice collapse, a catastrophic natural phenomenon. It has been 40 years since the volcanic debris avalanche associated with the 1980 eruption of Mount St. Helens, and our understanding of these events has grown considerably in the interim. Drawing on these advances, the book addresses all aspects of volcanic debris avalanches. Though previously overlooked in field-based geological and volcanological studies, these deposits are now known to be associated with most volcanoes and volcanic areas around the world. The book presents state-of-the-art ideas on the triggering and emplacement mechanisms of these events, supported by field and analogue studies, as well as new simulations tools and models used to determine their physical characteristic and hazards.
Measuring, monitoring, and modeling technologies and methods changed the field of glaciology significantly in the 14 years since the publication of the first edition of Fundamentals of Glacier Dynamics. Designed to help readers achieve the basic level of understanding required to describe and model the flow and dynamics of glaciers, this second edition provides a theoretical framework for quantitatively interpreting glacier changes and for developing models of glacier flow. See What's New in the Second Edition: Streamlined organization focusing on theory, model development, and data interpretation Introductory chapter reviews the most important mathematical tools used throughout the remainder of the book New chapter on fracture mechanics and iceberg calving Consolidated chapter covers applications of the force-budget technique using measurements of surface velocity to locate mechanical controls on glacier flow The latest developments in theory and modeling, including the addition of a discussion of exact time-dependent similarity solutions that can be used for verification of numerical models The book emphasizes developing procedures and presents derivations leading to frequently used equations step by step to allow readers to grasp the mathematical details as well as physical approximations involved without having to consult the original works. As a result, readers will have gained the understanding needed to apply similar techniques to somewhat different applications. Extensively updated with new material and focusing more on presenting the theoretical foundations of glacier flow, the book provides the tools for model validation in the form of analytical steady-state and time-evolving solutions. It provides the necessary background and theoretical foundation for developing more realistic ice-sheet models, which is essential for better integration of data and observations as well as for better model development.
Channelized Rivers Perspectives for Environmental Management Andrew Brookes Environmental Consultant, Reading, UK For centuries engineers have modified river channels in order to control floods, drain land, prevent erosion and improve navigation. The natural shape of many rivers has been dramatically changed, often with dire environmental consequences. This book demonstrates the role fluvial geomorphology can play in the design of river channels, both to lessen environmental impact and to enhance the success of channelization schemes. It considers the physical and biological impacts of channelization, the repercussions downstream and in the adjacent floodplain. Revised procedures and designs are proposed which minimize harsh environmental impacts. The interdisciplinary approach of the book offers river managers the opportunity to make more environmentally sensitive decisions in the course of their work. The book will be of great interest to geomorphologists, biologists and civil engineers working in the water industry.
**Please note that the PB version of this title is an exact reprint of the original HB published in 1994** This book is an up-to-date review of research and practice on the use of vegetation for slope stabilization and control of surface erosion caused by water and wind. From a basic understanding of the principles and practices of vegetation growth and establishment, it describes how vegetation can be treated as an engineering material and used to solve erosion and slope stability problems.
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.
This book presents selected articles from the workshop on "Challenges in Petrophysical Evaluation and Rock Physics Modeling of Carbonate Reservoirs" held at IIT Bombay in November 2017. The articles included explore the challenges associated with using well-log data, core data analysis, and their integration in the qualitative and quantitative assessment of petrophysical and elastic properties in carbonate reservoirs. The book also discusses the recent trends and advances in the area of research and development of carbonate reservoir characterization, both in industry and academia. Further, it addresses the challenging concept of porosity portioning, which has huge implications for exploration and development success in these complex reservoirs, enabling readers to understand the varying orders of deposition and diagenesis and also to model the flow and elastic properties.
This book describes the geological setting of Iran throughout geological history, referring to paleogeography and general geodynamics. Also, all structural units, faults, tectonic phases and orogeny occurred in the geology of Iran have been evaluated. Magmatic and metamorphic rocks along with ophiolitic complexes have extensive outcrops in Iran, and these rocks with Precambrian age constitute its basement. Study and identification of such rocks not only throws light on the geodynamic issues of Iran but also helps in recognition of the mode of formation and evolution of the sedimentary basins located within various structural divisions of the country. Moreover, the majority of metallic and non-metallic mineral deposits are associated either directly or indirectly with magmatic, and at time metamorphic, rocks. In the Magmatism and Metamorphism parts, it is tried to thoroughly consider the various aspects of the igneous rocks, whether intrusive, extrusive or young volcanoes, from the point of view of petrography, geochemistry and geodynamics. In addition, the major intrusive bodies of Iran have been presented along with their petrologic and chronologic specifications in tables, mentioning the bibliographic resources.
This re-issue, first published in 1964, is the first of a seminal series analysing the development of the study of landforms, from both the geographical and geological point of view, with especial emphasis upon fluvial geomorphology. Volume 1 treats the subject up to the first important statement of the cycle of erosion by W. M. Davis in 1889, and attempts to identify the most significant currents of geomorphic thought, integrating them into the broader contemporary intellectual frameworks with which they were associated. As well as dealing with such key figures as Werner, De Saussure, Hutton, Playfair, Buckland, lyell, Agassiz, Ramsay, Dana, Peschel, Powell, Gilbert and Davis, attention is also given to many less important contributions by American, British and continental workers. A spirited biographical treatment, attractively set off by contemporary portraits, diagrams and sketches, will make this book of great interest to the historian of science, and indeed to the general reader, as well as to the student and scholar in geomorphology, hydrology and any other earth science.
The surface of the Earth is and always has been in flux, constantly being remodelled by powerful natural forces. This text explores the processes and evidence of change, explaining how to recognize past events in the rocks, guiding through geological time to recreate past landscapes, and illustrating agents of erosion such as water, wind and ice sculpting solid landscapes, rocks amd materials recycling at the Earth's surface, and human impact on global cycles and climate change. This book complements the exhibition entitled "Restless Surface" in the Earth Galleries at the Natural History Museum, London.
This book describes repository solutions for all types of radioactive waste and residues in different geotechnical repository structures. The focus is initially on existing or planned final disposal sites in Germany and the process of finding sites. However, international comparisons are drawn, especially to locations in the US. This affects both the repository structures and the legal requirements. The radioactive substances considered include residues from uranium ore processing, as well as low and intermediate level radioactive waste up to heat generating, high level radioactive wastes, such as spent fuel and vitrified waste from reprocessing. In order to evaluate the repository structures and their inventories, a dimensionless radiotoxicity index Ai / Fi [activity of radionuclide quantity (Ai) related to the exemption limit of radionuclide (Fi)] has been introduced. This gives the reader a well-founded overview of the degree of inconsistency in the handling of safety requirements for the respective geotechnical environmental structures. This creates the necessary transparency on this issue, which has not been previously available and is required by stakeholders today. The long-term security, the duration of the observation period and the certainty of the safety prognosis are also discussed in the book as well as the participation of subsequent generations in current and possible future repositories. This is vital as nuclear energy will continue to be used worldwide in the long term. The international repository projects presented have all been subjected to the same evaluation criteria. This applies both to existing operational project as well as those about to be commissioned and the processes for seeking locations. Special attention has been paid to monitoring, both operational and long-term monitoring. This broad range of topics makes this book a very valuable read for both the interested public and the professional world.
This book encompasses the most challenging topics in earthquake engineering and seismology aiming at seismic risk reduction and reveals the outstanding progresses made in Europe in the past four years. Earthquakes pose a significant threat to countries around the world. But, equipped with the right knowledge and tools, engineers and seismologists can support policy and decision makers and building officials in creating a safer future for all of us. In this paradigm, the Third European Conference on Earthquake Engineering and Seismology (3ECEES) is organized in Bucharest (Romania) in September 2022 by the Romanian Association for Earthquake Engineering, Technical University of Civil Engineering of Bucharest and National Institute for Earth Physics. This outstanding scientific event is the third in a series started in 2006 in Geneva, Switzerland and continued in 2014 in Istanbul, Turkey. The papers included in this book are written by the most prominent contemporary European scholars in the two-folded fields of 3ECEES. The Distinguished Nicholas Ambraseys, along with 28 invited lectures providing the best knowledge in the fields of earthquake engineering and seismology, are shared with the general readership of this book. The book is organized in three parts, as follows: (1) Seismicity, engineering seismology and seismic hazard, (2) Seismic risk assessment and mitigation, and (3) Structural earthquake engineering. The 29 contributed papers for this book are shared among these three parts almost equally. Chapter "The Challenge of the Integrated Seismic Strengthening and Environmental Upgrading of Existing Buildings" is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.
This volume discusses the general physics of debris flows and various approaches to modeling - including the SEGMENT-Landslide approach - as well as the pros and cons of these approaches and how other approaches are sub-sets of the SEGMENT-Landslide approach. In addition, this volume will systematically unify the concepts of vadose zone hydrology and geotechnical engineering, with special emphasis on quantifying ecosystem consequences of storm-triggered landslides in a warmer climate setting. The reader will find a comprehensive coverage of concepts ranging from hillslope hydrology, porous granular material rheology and the fundamentals of soil properties, to state-of-the-art concepts of enhanced hydrological cycle with climate warming and a discussion of new approaches for future research.
The Juneau Icefield Research Project (JIRP) was formed to find a
prototype area to study Alaska's coastal glaciers and trends in
climatic change. For the past 57 years JIRP has conducted a
systematic study of key receding and advancing glaciers, including
Lemon Creek and Taku Glaciers. From this study, a model has been
developed to study the mass balance of these glaciers and their
relation to general atmospheric circulation. Taku's mass balance
was expected to provide a meaningful assessment of flakier climate
relations and environmental trends, specifically the increase in
atmospheric trace element pollution and global warming.
Historically, climate fluctuations, such as the Little Ice Age,
show that interglacial climate chage in not entirely stable, but
responds to even subtle changes in radiative forcing. Through
research, it has been made clear that even an abrupt change of
climate within years is not just a theoretical possibility but has
in fact happened in the prehistoric past. It is therefore clear
that in principal it could happen again. Human civilaization has
exploded under the mild and relatively stable climatic conditions
that have prevailed over the last 11,000 years.

This rock-based book is an attempt to link deep-water process
sedimentology with sandstone petroleum reservoirs. In presenting a
consistent process interpretation, the author has relied on his
description and interpretation of core and outcrop (1:20 to 1:50
scale) from 35 case studies (which include 32 petroleum
reservoirs), totaling more than 30,000 feet (9,145 m), carried out
during the past 30 years (1974-2004). This book should serve as an
important source of information for students on history,
methodology, first principles, advanced concepts, controversies,
and practical applications on deep-water sedimentology and
petroleum geology
Dams profoundly impact the geomorphology of rivers by altering the
natural patterns of water, sediment and energy flow in rivers.
These changes have a largely negative impact on aquatic and
riparian ecosystems upstream and downstream of the dam. Natural
dams also impact river geomorphology, although with positive and
negative repercussions for aquatic and riparian organisms. |
