This book aims to deliver significant scientific progress on the problem of the erosion of geomaterials, focusing on the mechanical/physical aspect. The chapters oscillate between a phenomenological outlook that is well grounded in experiments, and an approach that can offer a modeling framework. The basic mechanisms of internal and surface erosion are tackled one-by-one: filtration, suffusion, contact erosion, concentrated leak erosion, sediment and wind transport, bedload transport. These erosion mechanisms comprise both hydraulic structures (dams, dikes) and natural environments (wind, river, coastal). In this book, physicists and mechanicians share with the reader their most recent findings in their field work and study, while at the same time maintaining an accessible format. This compendium provides a well-documented information resource, and above all, a tool for approaching the issue of erosion of geomaterials in an up-to-date fashion for students, researchers and practitioners alike.

Erosion is the most common cause of failures at earth-dams,dikes and levees, whether through overtopping and overflowing, orinternal erosion and piping. This book is dedicated to thephenomenon of internal erosion and piping. It is not intended to beexhaustive on the subject, but brings together some of the latestinternational research and advances. Emphasis is placed on physicalprocesses, how they can be studied in the laboratory, and how testresults can be applied to levees and dams. The results from severalresearch projects in Australia, France, the Netherlands and theUnited States are covered by the authors. Our aim has been to shareour most recent findings with students, researchers andpractitioners. Understanding the failure of an earth-dam or a leveeby erosion in a unified framework, whether internal erosion orsurface erosion, requires continuous research in this field. Wehope that the reader will gain knowledge from this book that leadsto further progress in the challenging field of the safety oflevees and dams. Contents 1. State of The Art on the Likelihood of Internal Erosion ofDams and Levees by Means of Testing, Robin Fell and Jean-JacquesFry. 2. Contact Erosion, Pierre Philippe, Rémi Beguin andYves-Henri Faure. 3. Backward Erosion Piping, Vera Van Beek, Adam Bezuijen and HansSellmeijer. 4. Concentrated Leak Erosion, Stéphane Bonelli, Robin Fell andNadia Benahmed. 5.

This book is the international edition of the proceedings of IS-Seoul 2011, the Fifth International Symposium on Deformation Characteristics of Geomaterials, held in Seoul, South Korea, in September 2011.The book includes 7 invited lectures, as well as 158 technical papers selected from the 182 submitted. The symposium explored ideas about the complex load-deformation response in geomaterials, including laboratory methods for small and large strains; anisotropy and localization; time-dependent responses in soils; characteristics of treated, unsaturated, and natural geomaterials; applications in field methods; evaluation of field performance in geotechnical structures; and physical and numerical modeling in geomechanics. These topics were grouped under a number of main themes, including experimental investigations from very small strains to beyond failure; behavior, characterization and modeling of various geomaterials; and practical prediction and interpretation of ground response: field observation and case histories. Both the symposium and this book represent an important contribution to the exchange of advanced knowledge and ideas in geotechnical engineering and promote partnership among participants worldwide.

Geomaterials derived from the Earth’s crust and used in construction after appropriate processing are among the earliest raw materials exploited, processed and used by humans. Their numerous functional properties include accessibility, workability and serviceability, and these are explored within this volume. In modern society, sustainable use of raw materials, specifically those exploited in large volumes such as geomaterials for construction, raises questions of reducing extraction of primary resources and thus minimizing impacts on natural systems, and also employment of materials and technologies to lower emissions of deleterious substances into the atmosphere. This will be possible only if we fully understand the properties, processing and mode of use of traditional geomaterials. Although most of the papers within this volume were written by geologists, the contributions will also be of interest to those working in cultural heritage, monument conservation, civil engineering and architecture.

Site and Geomaterial Characterization addresses issues ranging from the micro-characterization of processes to the in situ evaluation of engineering properties of soils. This Geotechnical Special Publication contains over 40 technical papers that were presented at the GeoShanghai Conference held in Shanghai, China from June 6-8, 2006. This book is divided into four main sections, with all of the papers addressing one of the greatest challenges in geotechnical engineering research and practice: the evaluation of geomaterial properties with minimal to no disturbance states. The first section includes the general theme paper by James K. Mitchell, University Distinguished Professor, Emeritus, Virginia Polytechnic Institute and State University, who focuses on the study of physico-chemical behavior of soils, soil improvement and geomaterial characterization. The second section is completely devoted to recognizing the services of Dr. Mehmet T. Tumay, Georgia Gulf Distinguished Professor Emeritus in the Department of Civil and Environmental Engineering at Louisiana State University, for his immense contribution to research and practice in geotechnical engineering. The third section covers non-destructive evaluation and geophysical testing to address soil characterization problems relevant to foundation exploration, geoenvironmental evaluation and earthquake related topics. Finally, the fourth section contains other in situ testing methods that deal with the analysis of field data and interpretation of soil properties, as well as simulation of in situ testing using numerical methods.

Failure in Geomaterials offers a unified view of material failure as an instability of deformation modes framed within the theory of bifurcation. Using mathematical rigor, logic, physical reasoning and basic principles of mechanics, the authors develop the fundamentals of failure in geomaterials based on the second-order work criterion. Various forms of rupture modes and material instabilities in granular materials are explored both analytically and numerically with lab experimental observations on sand as a backdrop. The authors provide a clear picture of inelastic deformations and failure of geomaterials under various loading conditions. A unique feature of the book is the systematic application of the developed theory to the failure analysis of some selected engineering problems such as soil nailing, landslides, energy resource extraction, and internal erosion in soils. Provides the fundamentals of the mechanics of geomaterials for a detailed background on the subject Integrates a rigorous mathematical description of failure with mechanisms based on microstructure Helps users apply mathematical models of solid mechanics to engineering practice Contains a systematic development of the fundamentals of failure in heterogeneous multiphasic materials
