Slano Blato Landslide

Slano blato landslide is located at 45°54? N 13°51? E in the Eocene flysch region of western Slovenia. The landslide was first mentioned in 1887 with the occurrence of an earth flow destroying the main road in the valley about 2 km away. The landslide was thereafter remediated with a series of torrential check dams along the Grajš?ek stream. The landslide remained stable till November 2000, when during heavy rainfall, a large landslide of mud and debris was triggered, moved along the Grajš?ek stream at a speed of up to 100 m/day and threatened the village of Lokavec situated in the valley below. The landslide is about 1,600 m long, 60 to 250 m wide, with a total sliding mass of about 900,000 m3 located between 270 and 650 m asl. In 2001 and 2002, approximately 230,000 m3 of accumulated debris material were removed from the area of a rockfill dam that was built about 300 m above the village as a part of protection measures, followed by surface and subsurface drainage works and a construction of three RC shafts/wells in 2004, with gradual construction of additional eight RC shafts that were completed in 2007. The landslides is long and relatively shallow with variable slope inclination. Source: Pulko, B., Majes, B. & Mikoš, M.
