Opis

Geotextile encapsulated sand elements are relatively new, and the number of applications is growing in river and coastal engineering. 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 Geosystems. Design Rules and Applications four types of geotextile sand elements are distinguished: geo-bags, geo-mattresses, geotextile tubes and geotextile containers. The book is an essential reference for professionals and academics interested in River and Coastal Engineering, but aims also at those interested in Geotechnical Engineering.
