Application of geosynthetics as hydraulic barriers in flood protection embankments

Using geosynthetics as a substitution for natural low permeability materials such as clays and silts have come to fore in last few decades. Numerous advantages in their performance and installation procedure make them popular for use inside flood protection embankments. Geomembrane and geosynthetic clay liner (GCL) are commonly used as hydraulic barriers. However, some limitations of these materials need to be stressed both from hydraulic stability and shear strength point of view. An example of application of GCL for reconstruction of embankment Virje - Otok Brezje, Varaždin County is demonstrated in this paper. The installation of GCL with carefully chosen characteristics proved that man-made materials such as geosynthetics can be successfully applied for ensuring stability of flood protection embankments.
