Sheet erosion rates determined by using dendrogeomorphological analysis of exposed tree roots : two examples from Central Spain

Abstract

Two sites on the northern slope of the Guadarrama Mountains were selected because they showed high denudation morphologies due to accelerated soil-erosion processes caused by human influence, resulting in exposed roots. The method applied is based on the morphological pattern of roots, defined by the growth-ring series of the sampled roots in order to confirm the validity of the criteria used and to make the estimations of erosion more accurate, several anatomical indicators of exposed and non-exposed Pinus sylvestris roots were characterized. The study entailed a statistical analysis of exposure time and erosion depth. The influence of environmental factors affecting the variation in velocity of the erosion processes was also examined
