The papers presented in this volume describe the latest developments from around the world on ground improvement by densification and reinforcement. They describe new research into improving the understanding of the problems facing geotechnical engineers working in the field of ground improvement and the advances in the techniques available to them. Numerous case studies show how new and improved methods have actually been applied over a wide variety of ground conditions.
Geotextile encapsulated sand elements are three-dimensional systems manufactured from textile materials, non-woven materials or combinations of textile and non-woven materials that are filled with sand on-site. These systems are relatively new and the number of applications is growing in river and coastal engineering. Quite often Geosystems are mentioned as a possible solution, but planners, designers and contractors feel rather hesitant about the application of geotextile encapsulated sand elements due to a lack of experience and adequate design rules. The use of geosystems has the advantage that local material can be applied and that no (expensive) quarry stone needs to be extracted and transported from the mountains to the site. Compared to traditional construction methods (with quarry stone) the application of geotextile sand filled elements may add considerable operational advantages to the execution of marine works and may offer attractive financial opportunities. In the application of geotextile encapsulated sand elements however, proper attention should be paid to the laying down of different responsibilities of the parties in the contract. In Geosystems. Design Rules and Applications four types of geotextile sand elements are distinguished, each with specific properties: geo-bags, geo-mattresses, geotextile tubes and geotextile containers. The focus is on the use of geosystems filled with sand as a construction in river and coastal engineering. Geosystems filled with sludge are not covered. The chapters “Introduction” and “General design aspects” are followed by four chapters of the same structure dealing with the various systems. Each of these four chapters starts with a general description and applications and ends with a calculation example. Design aspects are dealt with in the remaining paragraphs. Geosystems. Design Rules and Applications is based on research commissioned by the Dutch Rijkswaterstaat and Delft Cluster. The realisation of the Dutch version was coordinated by a CUR-committee. The English version is a translation of the Dutch version (CUR-publication 217). However, new developments have been added and the text was checked once again and improved. Geosystems. Design Rules and Applications is an essential reference for professionals and academics interested in River and Coastal Engineering, but aims also at those interested in Geotechnical Engineering.
Interfacial Science for Geosystems Engineers provides geoscientists the connections between the nano-scale physico-chemical interactions between fluids and minerals and the core/field-scale observations to manage energy extraction, water resources and subsurface storage, timely topics central to the energy transition. Packed with latest research and recent developments, chapter learning objectives, and illustrative diagrams, tables and charts throughout, this specialized volume will help geosystems engineers tackle the above challenges, by systematically going through the basics of surface and interfacial tension, capillarity, surfactants, surface free energy, adsorption, electrokinetics, colloidal stability, equilibrium and stability of thin liquid films, wettability, microemulsions, emulsions and foams, and polymers for subsurface applications. Useful as a teaching, training or reference text, Interfacial Science for Geosystems Engineers prepares today's subsurface scientists and engineers to tackle two pressing problems in the energy transition, by introducing recent developments on how to remove CO2 from our environment and how to wean ourselves off fossil energy while meeting growing energy demands. - Describes fundamentals and recent advances in interface and nanoparticle/colloid dispersion science - Offers critical analysis of the latest research and developments relevant to extracting low-carbon and other energy materials from, and store CO2 and H2 in, subsurface formations - Helps guide geosystems (especially energy) engineers on how to solve the problems they encounter in the rapidly evolving Energy Transition
This book is the proceedings of the 11th Kongsberg seminar, held at the Norwegian Mining Museum in the city of Kongsberg, about 70 km Southwest of Oslo. The Kongs berg district is known for numerous Permian vein deposits, rich in native silver. Mining activity in the area lasted for more than 300 years, finally ceasing in 1957. The first eight Kongsberg seminars, organized by professor Arne Bj0rlykke, now director of the Norwegian Geological Survey, were focused on ore-forming processes. These seminars have always been a meeting point for people with a variety of geological backgrounds. Since 1995, the Kongsberg seminars have focussed on geological processes, rather than on specific geological systems, and the selection of invited speakers has been strongly influenced by their interest in the dynamics of geological systems. In 1995 and 1996, various aspects of fluid flow and transport in rocks, were emphasized. The first "Kongsberg proceedings" (of the 1995 seminar) published by Chapman and Hall (Jamtveit and Yardley, 1997) contained 17 chapters dealing with a wide range of topics from field based studies of the effects of fluid flow in sedimentary and metamorphic rocks to computer simulations of flow in complex porous and fractured media. In 1997, the focus was changed to growth, and dissolution processes in geological systems.

This IMA Volume in Mathematics and its Applications STOCHASTIC MODELS IN GEOSYSTEMS is based on the proceedings of a workshop with the same title and was an integral part of the 1993-94 IMA program on "Emerging Applications of Probability." We would like to thank Stanislav A. Molchanov and Wojbor A. Woyczynski for their hard work in organizing this meeting and in edit ing the proceedings. We also take this opportunity to thank the National Science Foundation, the Office of N aval Research, the Army Research Of fice, and the National Security Agency, whose financial support made this workshop possible. A vner Friedman Willard Miller, Jr. v PREFACE A workshop on Stochastic Models in Geosystems was held during the week of May 16, 1994 at the Institute for Mathematics and Its Applica tions at the University of Minnesota. It was part of the Special Year on Emerging Applications of Prob ability program put together by an organiz ing committee chaired by J. Michael Steele. The invited speakers represented a broad interdisciplinary spectrum including mathematics, statistics, physics, geophysics, astrophysics, atmo spheric physics, fluid mechanics, seismology, and oceanography. The com mon underlying theme was stochastic modeling of geophysical phenomena and papers appearing in this volume reflect a number of research directions that are currently pursued in these areas.
Pearson Prentice Hall's Encounter Geosystems supplement gives students a new way to visualize key topics in physical geography using Google Earthtrade; and saves instructors time by providing well-organized, assignable exercises.
A review of the existing applications of geosynthetics and geosystems in hydraulic and coastal engineering, with an overview on material specifications, structural components, relevant tools during conceptual and detail design, possible applications, and execution aspects. A more detailed description is given of new or lesser-known systems and applications. Additional basic information on design methodology and geosynthetics is included to provide a basic framework of information for design purposes.
