altProject: ТР 2010
Project Duration: 1 April 2008 to 31 March 2010
Project Manager: Prof. Dr. Duško Sunarić
Project Team: Dr. V. Anđelković; Dr. N. Stojnić; Prof. Dr. D. Jevremenović; Dr. B. Abolmasov; Doc. Ž. Lazarević; S. Djurić; B. Ljumović; R. Vasić; S. Nedeljković; and M. Lolin

Landslides, rockfalls, and mudflows are phenomena inherent in unstable soils and are widespread in Serbia. Landslides measuring millions of cubic meters are deemed to be natural disasters. They are especially dangerous if they obstruct streams and create large lakes. Erosion of these natural dams can result in treacherous flood waves. There are many examples of such events in Serbia, including Ovčar Banja (on the Zapadna Morava River), Zavoj (on the Visočica River), and Jovac (on the Jovac River). The infamous Joc Rockfall (in the Danube River Basin, near the entrance to the Iron Gate Gorge), dammed 1/3 of the river channel, obstructed the flow, backed-up river traffic on the Danube, and interrupted road traffic for nearly six months.

All these events belong to the past century but there is a likelihood of recurrence. The Serbian Ministry of Science and Technological Development supported this project with the goal of gaining insight into geological and other conditions which lead to such events. The project was implemented by the Jaroslav Černi Institute for the Development of Water Resources, and the School of Mining and Geology, University of Belgrade.

Project Activities

  • Data collection for the identification and assessment of riverside landslide risks and hazards  in Serbia;
  • Project-specific field surveys;
  • Assessment of seismic regimes and hazards (autochthonous and allochtonous earthquakes and related mega-landslides and rockfalls);
  • Development of a region-specific risk and hazard assessment methodology based on international guidelines (IUGS Working Group on Landslides, Committee on Risk Assessment, 2005; and Landslides Risk Management: Concepts and Guidelines, Australian Geomechanics, 2000).

Project Deliverables

  • Progress reports and final report;
  • Public presentation, presentations at national and international conferences, and articles in national journals; and
  • A monograph entitled: “Seismicity and Exogeodynamic Phenomena (Landslides and Rockfalls) in West Serbia "


In this regard, an earthquake vulnerability map was produced based on the results of comprehensive investigations conducted within the scope of this project.  (Figure 3)

Figure 3:  Map showing types of potential soil vulnerability to major earthquakes: 1. Mostly dynamic deformations (fractures, funnel-like depressions, etc.); 2. Dynamic deformations and landslides; 3. Frequent deep landslides containing dominant sediments; 4. Consequent landslides along slopes; 5. Consequent landslides along slopes with diluvial deposits (generally small-scale); 6. Rockfalls and taluses from carbonate cliffs, and subordinate landslides; 7. Rare small-scale landslides and taluses (grus); 8. Taluses and rockfalls, with rare landslides along slopes.
