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.

This timely book is about how to design alternatives to reduce coastal flood and wave damage, erosion, and loss of ecosystems facing an unknown future of sea level rise. The latest theories are interlaced with applied examples from the authors' 48 years of experience in teaching, research, and as a practicing, professional engineer in coastal engineering. The design process takes into consideration all the design constraints (scientific, engineering, economic, environmental, social/political/institutional, aesthetic, and media) to meet today's client needs, expectations, and budgets for an uncertain future.The book is organized as a textbook for graduate students. And, it is a self-contained reference for government and consulting engineers responsible for finding solutions to coastal hazards facing the world's coastal populations. New solutions are included in the book that help people of all socio-economic levels living at the coast. Both risk reduction metrics quantified in monetary terms, and increased resilience metrics quantified as vulnerability reduction must now be taken into consideration to make equitable design decisions on hazard mitigation alternatives.In the Anthropocene Era, under 'deep uncertainty' in global mean sea level predictions for the future, today's designs must mitigate today's storm damages, and be adaptable for the unpredictable water levels and storms of the future. This book includes a design 'philosophy' for water levels to year 2050 and for the long term from 2050 to 2100. Multiple spreadsheets are provided and organized to aid the design process.This is an exciting time to be 'thinkers' as Civil/Coastal engineers.Related Link(s)

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.

The First Southern African Geotechnical Conference was organised by the Geotechnical Division of the South African Institution of Civil Engineering (SAICE) under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) and took place at Sun City, South Africa on 5 and 6 May 2016. More than 60 papers were rec

This book comprises chapters on scour and erosion related issues. It is an outcome of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) Technical Committee 213 Workshop on Scour and Erosion that was held on December 16, 2020. The ISSMGE TC213 Workshop was attended by 368 participants from 12 different countries worldwide. The contents of this book reflect recent advances in the mechanics and countermeasures of scour and erosion, including coastal protection, erosion control, etc. Covering practical issues of geotechnical engineering with academic and research inputs, this volume will be a useful reference for academia and industry alike.

This book constitutes the refereed proceedings of the 4th Computational Methods in Systems and Software 2020 (CoMeSySo 2020) proceedings. Software engineering, computer science and artificial intelligence are crucial topics for the research within an intelligent systems problem domain. The CoMeSySo 2020 conference is breaking the barriers, being held online. CoMeSySo 2020 intends to provide an international forum for the discussion of the latest high-quality research results.

This volume contains the proceedings of the 12th International Conference on Geosynthetics (12 ICG), held in Roma, Italy, 17-21 September 2023. About 750 Authors - Academics, Researchers, Students, Practitioners, Contractors and Manufacturers – contributed to the peer-reviewed papers of this volume, which includes the Giroud lecture, the Bathurst lecture, the Rowe lecture, four keynote lectures and 296 technical papers. The content of these proceedings illustrates the sustainable use of geosynthetics in a variety of innovative as well as consolidated applications. After the sustainability implications in the correct use of geosynthetics, the ability to overcome the natural events effects, often related to the climate change, and to adequately afford the human activities (as the increase of pollution) forced to refer to a new keyword: Resiliency. The 12 ICG intends to become the base for the next step, hence the conference theme is 'Geosynthetics, Leading the Way to a Resilient Planet'. The conference topics, through general and parallel sessions, invited presentations and keynote lectures, address the most recent developments in geosynthetic engineering, and stimulate fruitful technical and scientific interaction among academicians, professionals, manufacturers, students. The 12 ICG proceedings contain a wealth of information that could be useful for researchers, practitioners and all those working in the broad, innovative and dynamic field of geosynthetics.
