Rezumat:

This study consisted in a precise mapping project (GPS field campaign, on-screen digitization
of the topographic maps at 1:5.000 scale and updated with ASTER mission) of the Ceahlãu mountain
area in Romanian Carpathians in order to address the snow avalanche risk management, surveying
and monitoring. Thus we considered the slope, aspect, altitude, landforms and roughness resulted
from a high resolute numerical terrain model (31 square km at 1: 5.000 scale resulted in a spatial
resolution of 3 m by the help of Topo to Raster tool). These parameters were calibrated after a model
applied into Tatra Mountains and used over Ceahlãu Massive. The results were adapted and
interpreted considering to the European Avalanche Hazard Scale. This work was made in the context
of the elaboration of Risk Map and is directly concerning both in the security of tourism activities but
also in the management of Natural Park Ceahlãu. The extension of this method to similar mountain
areas is ongoing and finally the work has also an educational purpose.
