Formation conditions of debris flow on 15.5. 2014 in Smutná valley (Western Tatra mts.)

The aim of this bachelor's thesis is to determinate conditions what trigger debris flow on 15. 5. 2014 in Smutna valley (Western Tatra Mts.). Statistical method 4σ and additional global and local event duration model and local event precipitation model were used. Derived values with thresholds based on these models were compared. Geomorphological mapping of debris flow using GPS was made. Another base characteristics of debris flow werefound out, e.g. areal debris accumulation or leeves, wide and depth of debris flow path. Derived rainfall values from 4σ model, event-duration model and event precipitation model was exceeded. Debris flow with it's lenght belongs to more extensive debris flows, but e.g. path widht is common in Western Tatra Mts. Keywords: landslide, debris flow, threshold, Western Tatra Mts
