Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 138.Subduction zones helped nucleate and grow the continents, they fertilize and lubricate the earth's interior, they are the site of most subaerial volcanism and many major earthquakes, and they yield a large fraction of the earth's precious metals. They are obvious targets for study--almost anything you learn is likely to impact important problems--yet arriving at a general understanding is notoriously difficult: Each subduction zone is distinct, differing in some important aspect from other subduction zones; fundamental aspects of their mechanics and igneous processes differ from those in other, relatively well-understood parts of the earth; and there are few direct samples of some of their most important metamorphic and metasomatic processes. As a result, even first-order features of subduction zones have generated conflict and apparent paradox. A central question about convergent margins, for instance--how vigorous magmatism can occur where plates sink and the mantle cools--has a host of mutually inconsistent answers: Early suggestions that magmatism resulted from melting subducted crust have been emphatically disproved and recently just as emphatically revived; the idea that melting is fluxed by fluid released from subducted crust is widely held but cannot explain the temperatures and volatile contents of many arc magmas; generations of kinematic and dynamic models have told us the mantle sinks at convergent margins, yet strong evidence suggests that melting there is often driven by upwelling. In contrast, our understanding ofwhy volcanoes appear at ocean ridges and "hotspots"--although still presenting their own chestnuts--are fundamentally solved problems.

Sediments and Ecohyraulics is comprised of papers submitted to the 6th International Conference on Cohesive Sediments (INTERCOH 2005) held in Saga, Japan, September 2005. The papers are divided into two major categories. The first is basic processes, including erosion, settling, flocculation, and consolidation. The second major catagory is application of the understanding of cohesive sediments to address specific issues, including waterway and part management, fluid mud behavior, and contaminiated sediment management.

The book is the first of its kind to deal with almost the entire swath of water resources assessment, development and sustainable management. The idea of the book crystallized during the long journey of the Editors on various facets of water issues in India and abroad during their extended association, at all levels with the Ministry of Water Resources, River Development and Ganga Rejuvenation, as well as International Organizations dealing with water. Currently water-stressed, India is likely to become water scarce in not too distant a future. The global freshwater supply and its sustainable use for human consumption, and conservation of the ecosystem have never come under such a rigorous scrutiny before. The unplanned and reckless exploitation of this precious resource have led to a crisis situation, compounded by a real threat of climate change. This book is, therefore, timely and of particular relevance not only to India but the entire world. The book contains 20 chapters, beside the lead article by the Editors. The chapters are contributed by the eminent professionals, researchers, academicians and civil society representatives having an in-depth understanding of the issues. The contents of the chapters have been chosen to represent all aspects of water. The assessment of water resources using satellite data and in-depth analyses of groundwater sector like, the Aquifer Mapping Programme initiated by Government of India, application of gravity satellite data to assess the resource build up, artificial recharge of aquifers and its contamination, are dealt with by eminent experts. The articles on sustainable management of water through good governance by community participation and involvement of civil society are placed. Flood management both through a basin level approach as well as by building resilience in vulnerable areas is discussed. Other critical issues like water bodies management, constitutional provisions, water governance and financial issues, hydro-power and need of research and development in this sector are also dealt with aptly. In view of emerging crisis and complexities in this sector the future pathways and the paradigm shift that is required in administrative and policy level is also discussed.

This book highlights the need for effective water governance in India given the fact that the country has been facing serious water stress in recent years. The water management in the country needs a serious scientific understanding coupled with the cooperative approach rather than a competitive one. It looks at current water regulations and underlines the need for overhaul of some laws to ensure that high water usage efficiency is attained, groundwater depletion is arrested and management of available resources is carried out in a disciplined manner. It also looks at the role of stakeholder engagement and pricing as a mechanism to manage demand in the wake of rapid population growth and industrialization.

The study of nature is a complex science involving many different fields from geology and meteorology to biology, zoology, and botany. This complexity indicates nature's broad scope of impact. It is at once beautiful and dangerous, displaying power beyond human control. An understanding of the basic principles and concepts of the study of nature is therefore both enriching and practical. In The Handbook of Nature, authors Frank R. Spellman and Joni Price-Bayer provide a comprehensive guide to the study of nature in terms the layperson can grasp easily. This accessible reference work is for the non-specialist looking for quick, accurate information on all aspects of the study of nature. The handbook is arranged thematically for a logical and user-friendly progression through the material. It includes chapters on the earth's structure and landforms, the atmosphere and weather, water and water sources, and the many different forms of life from single-celled organisms to complex vertebrates. Along with basic natural scientific principles, the authors look closely at the consequences of human interactions with the environment we inhabit. This reference concludes with a glossary and index, and each chapter provides further resources and recommended reading. It is an essential tool for students and professionals alike.

Microporomechanics encapsulates the study of the micromechanics of porous media. Porosity is the most prominent heterogeneous property of all natural and most engineered composite materials, and is key to the understanding and prediction of macroscopic materials behaviour. As new experimental techniques such as nanoindentation now provide unprecedented access to micromechanical properties and morphologies of materials, it becomes possible to trace these features from the nanoscale to the macroscale of day-to-day engineering applications, and predict transport properties, stiffness, strength and deformation behaviours within a consistent framework of microporomechanics. Authored by recognised leading experts in the field of microporomechanics Introduces high quality landmark research that proposes a new framework for the description of the behaviour of porous materials Composed of a logical and didactic build-up from fundamental concepts to state-of-the-art theory Synergises the disparate subject areas of poromechanics and micromechanics Includes a variety of original problem sets that provide a hands-on application of the homogenization theories to specific materials configuration

"Microporomechanics" provides a first introduction to the micromechanics of porous media, and offers an invaluable resource for academic and industrial research scientists and engineers. It will also appeal to graduate students in biomechanics and bioengineering, civil and environmental engineering, geophysics and geomechanics, materials science, and engineering related to petroleum and gas exploration.
