Geosynthetic Technologies in Hydraulics

Abstract

Geosynthetics are well known for substituting mineral filter layers for revetments. Apart from this established and common application they offer more specific and technical solutions for coastal and inland water structures. Typical hydraulic constructions like breakwaters and dikes can be strengthened and optimised using geotextiles or geosystems (bags, tubes, etc.). Till today the potential of geosynthetics for civil works in the marine environment is underestimated. Furthermore, the awareness by designers, construction companies and project owners for geotextile alternatives, saving time, money and enhancing the carbon footprint, can be substantially increased. Main reasons for the ignorance are missing design guidelines and a not existing general overview of their applicability in coastal zones and inland waters. This paper is intended as a first step towards a holistic approach to geosynthetics in hydraulics.
