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.

"New and promising developments in hydraulic engineering, such as geotextile- encapsulated sand elements, are sometimes hampered by the lack of design rules. That's probably the reason why planners, designers and contractors are therefore rather hesitant to apply geosystems. Most of the design rules are empirical in nature and this means that existing experience is therefore required to design new structures. For this reason it is a challenge to design a structure when only limited experience is available with that type of structure. This was the idea of the CUR-committee F42 (CUR Building & Infrastructure) and therefore existing experiences and research results where gathered and bundled in the CUR-publication 217 "Ontwerpen met geotextiele zandelementen". The original CUR-217 publication is in Dutch and this manual makes the contents of this publication available for an international audience. Most of the manual is a translation of CUR-217. However, additions have been made to give the manual more international relevance. In addition some improvements and corrections have been made"--Provided by publisher.

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 received from authors in South Africa, Botswana, Kenya, Tanzania, Uganda, Algeria, Austria, France, Germany, Switzerland and the United Kingdom. They represent consulting engineers and engineering geologists, contractors, academics and product specialists. The papers were grouped into the following themes: Foundations, Mining and Tailings, Modelling and Design, Site investigation, Soil Properties and Soil Reinforcement and Slopes. The wide range of topics is considered to be thoroughly representative of the current activities of the geotechnical industry in the Southern African Region.

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 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.

Mit großer Spannung wurde sie erwartet, auch von Nicht-Katholiken: Die Umwelt-Enzyklika von Papst Franziskus nimmt die heute entscheidenden Themen in den Blick; es geht um die geht um soziale, ökologische und politische Zusammenhänge. Wohl selten war ein päpstliches Schreiben so aktuell und brisant und vor allem relevant für alle Gesellschaftsschichten und Menschen weltweit. Mit "Laudato si" beweist Franziskus, dass die Kirche nach wie vor eine unverzichtbare Stimme im Diskurs zur Gestaltung der modernen Welt ist. Wer verstehen will, wie Papst und Kirche die großen Herausforderungen unserer Zeit bestehen wollen, kommt an diesem Werk nicht vorbei. Ein Muss für jeden, der an den drängenden Fragen unserer Zeit interessiert ist.
