Slope deposits in the Upper Nalón River Basin (NW Spain) : an approach to a quantitative comparison

Auteur :
JIMÉNEZ SÁNCHEZ, M.

Description :
The Upper Nalón River Basin (Cantabrian Mountains, NW Spain) exhibits a variety of slope processes and deposits including landslides, rockfall and soil creep. Geomorphic maps were used to quanitatively ascertain the relationships between these deposits and topographic characteristics of exposure, gradient and altitude at the nodes of a square grid with 250-m spacing (N=926). A correspondance analysis allows the analysis of qualitative and quantitative variables. The results suggest that lithology is the main conditioning factor of the differences and similarities between deposits.
