Contribution To Avalanche Modelling In The Velka Fatra National Park, An Example Of The Krizna-Massif

The paper analysis the facts about snow and avalanches assembled with the aid of a geographic information system. Based on a digital terrain model and landscape cover mapping, we have identified the major topographic features enabling us to locate the release points for the avalanches. These ones were consequently used as entry data for a dynamic avalanche model. For the modelling, we choose the area Krizna in the National Park Velka Fatra where the avalanche prevention is required very much. In the second part of this work we discuss eighteen avalanches with smaller release zones, with a release depth of one meter, simulated, by the ELBA+ model. The outcomes of these simulations are a map for potential release zones and evaluations of the potential avalanche paths for the chosen release parameters. These tools can serve as an appropriate basis for landscape planning with the aim to prevent catastrophes caused by avalanches in Krizna. With modified parameters, the same can be implemented for other mountains in Slovakia.
