Extreme precipitation events and landslides activation in Croatia and Bosnia and Herzegovina

This paper focuses on analysing the relationship between extreme precipitation conditions and rainfall-triggered landslides in Croatia and Bosnia and Herzegovina. During winter and spring of 2013, extreme weather conditions (re)activated more than 900 shallow landslides in the NW Croatia. In May 2014 the low-pressure cyclone Tamara (Yvette) affected a large area of southeastern and Central Europe, causing floods and landslides with the greatest damages in Bosnia and Herzegovina. The most affected area was central part of Bosnia and Herzegovina with more than 7100 (re)activated landslides. Analysis of extreme precipitation conditions showed that both the short- and long-duration rainfalls were responsible for the large number of landslide initiations in NW Croatia and central Bosnia and Herzegovina. Understanding the relationship between landslides, precipitation conditions and climate change are therefore crucially important in planning a proactive approach in landslide risk reduction.
