This paper presents the study of the morphodynamics of dunes of Boca Sur neighborhood, located at the metropolitan region of Concepción, Chile. The purpose is to establish criteria to the use and occupation of the area for the construction of an urban park. A characterization of the dune’s field and surrounding area were made, including its environmental and social components. The method used was field’s observation, literature review, elaboration of dunes’ topographic profile and comparative analysis of satellite images from 1978 and 2011. The results show a loss of beach and dunes’ territory in the Boca Sur neighborhood caused for natural and human factors, as well as possible natural risks to which the park’s construction area is exposed due to its localization, relief and dynamics of natural elements. Through microzoning of the park’s area, we conclude establishing preferential uses and restrictions to the occupation of the dune field, that from the standpoint of sustainable use are considered relevant for a future intervention.
