Abstract

PENA-CORTES, Fernando et al. Dinámica geomorfológica de la costa de La Araucanía. Rev. geogr. Norte Gd. [online]. 2014, n.58, pp.241-260. ISSN 0718-3402.  http://dx.doi.org/10.4067/S0718-34022014000200013.

This paper describes the geomorphology of the coast of La Araucania, using methods proposed by Tricart (1985) Endlicher (1985) and the classification methods of Francke et al. (2004). Based on morphological, morphometric, morphogenetic and land use patterns, the most representative geomorphic units were the mountain range of metamorphic rock, cord metamorphic rock mountain with granite intrusions, both Paleozoic, the metamorphic rock platform and the fluvial-marine plain represented by wetlands of high ecological value. Water erosion was low to moderate in much of the study area and is mainly associated with human factors, such as the historic reduction and change in vegetation cover, poor agricultural practices and almost no application of soil conservation practices.

Keywords : Coastal geomorphology; hydric erosion; geomorphological units; mor-phometric; morphogenesis; cultural landscape.
