Differing responses to extreme rainfall events in headwater areas recorded by wood anatomy in roots (Gorce Mountains, Poland)

Auteur(s) et Affiliation(s)



Description :
Fieldwork was carried out in the Gorce Mountains, a range of flysch-type mountains in the Polish Carpathians. In order to date extreme geomorphic events precisely, a dendrogeomorphic approach was performed based on anatomical changes in exposed roots. The results showed that the headwater areas experienced a variety of geomorphic processes. The timing of processes was assessed for the years 1944 to 2001. The main difference between the roots can be observed between the upper and lower parts of the headwater area. In the upper part of the headwater area, anatomical changes within the roots were observed when heavy rainfall events occurred, i.e. in 1958, 1970, 1971, 1972, and 1985. Roots in the lower part of the headwater area had become exposed during continuous rainfalls in 1997 and 2001. This research provides a fundamental review of dendrogeomorphological methodology applied to the identification of extreme geomorphic events acting within headwater areas.
