Leva Reka Landslide

Moderate to large debris-flow, approximately 19000 square maters in area, developed after the May 2014 cyclone storm in Serbia, locally with 150-200 mm of rainfall per day during tree-day period 13-16.5.2014. Typical example of landslide damming (see images from the provided link in KMZ file). Landslide lake developed 150 m upstream, approximately 5 m deep. The dam is subsequently breached, and the water is normally running out from the lake, the usual hydrographic conditions on The Leva Reka stream are soon to be expected (within a year or so) as runout material is being gradually flushed away. The material is represented by debris of weathered flysh formations, predominantly shale and sandstone (clayey matrix). There is no evidence on previous activity. Pre-event morphometry of the slope was contributing to landslide development, as relatively deep and steep incisions and gullies have been identified on old topographic maps. Local road on the opposite side of the valley was completely destroyed. It was soon brought to function but not entirely reworked ever since. Provided KMZ has a link where one can find photographs of the site (also here: http://geoliss.mre.gov.rs/beware/form/detalji_klizista.php?id=1040). The report from this link (together with some 2000 other landslide reports) is the result of the landslide mapping campaign within the framework of BEWARE project in Serbia in 2015 (http://geoliss.mre.gov.rs/beware/). Unfortunately, this short report is only in Serbian but the photographs can be found at the bottom of the page. This is one of the landslides that are not common in our practice in Serbia, and further scientific investigations are expected.
