The landslide Slano Blato, is situated above the village Lokavec near Ajdovščina in the weat of Slovenia. It has a relatively long history and was first mentioned m a document in 1887 At that time it destroyed a part of a main road and reconstruction works took 17 years In the last decade, movement of the landslide was observed in November 2000, when it reached distances of 60-100 m/day. By means of geotechnical research work on the landslide in the year 2004, several rheological tests were also carried out, which is not usual tor geotechnical research work. A stability analysis was carried out numerically by applying the Burger elasto-plastic model. The model took into account geomechanical and rheological characteristics of the landslide.
