Debris Flows in Călimani Mountains and Lotrului Valley

UAV and field survey investigation of a landslide triggered debris flow and dam formation in Eastern Carpathians

“…In the flysch belt of the Eastern Carpathians (Romania) (Belayouni et al, 2009;Miclauș et al, 2009), where the study site is located (Figure 1A) most landslides and landslide triggered debris flow occur in remote locations and usually do not pose a significant hazard (Mihu-Pintilie et al, 2014b;Mihu-Pintilie et al, 2016) (Figure 1B). However, some debris flow-slide events have impacted road infrastructure located at the base of slopes and caused extensive forest destruction, with a moderate impact on the local economy (Pop et al, 2017). In some cases, the debris fan deposits lead to the formation of temporary or, very rarely, longterm water accumulation behind the dams (Mihu-Pintilie, 2018a).…”
