Dendrogeomorphology

In wooded areas where there is no monitoring of geomorphological processes, the dendrogeomorphological methods represent efficient alternatives for spatio-temporal reconstruction of their activity. The dendrogeomorphological studies mainly concern reconstruction of geomorphological process activity in natural context (snow avalanches, debris flow, rock falls), but also in conditions of human disturbance (mining areas, hydroelectric areas, touristic areas).

Until present, dendrogeomorphological studies were elaborated in Southern Carpathians (Fagaras Massif, Piatra Craiului Mountains, Bucegi Mountains, Parang Mountains), Apuseni Mountains and Eastern Carpathians. These were elaborated by the specialists of the dendrogeomorphological laboratories of West University of Timisoara, Babes-Bolyai University of Cluj-Napoca, Stefan cel Mare University of Suceava in collaboration with forestry specialists (from ICAS). The research was focused on the reconstruction of the snow avalanches activity from some corridors and on debris flow activity and sediment transfer in mining areas.

Other dendrogeomorphological approaches were focused on the reconstruction of fluvial activity and processes for Late Holocene using the relations of the dendrochronology of subfossil trunks excavated from the analyzed fluvial deposits.

For the future, in parallel with continuing the initiated dendrogeomorphological studies, our team intend:

  • The extension of studies in other areas with high dendrogeomorphological interest in the mountain space, at local and regional scale, of specific geomorphological processes (snow avalanches, debris flow, rock fall);
  • Deciphering the way that we can use subfossil trunks in order to elaborate a long dendrochronological series with high replicability for an extended period from Medium and Superior Holocene and the use of the obtained series with the aim to date the channel changes and the behaviour of the river channels.
